A Chemical Engineer's daughter asks

When i browse on internet today I came across a web blog on climate change and found A Chemical Engineer's daughter questions community on "What if global warming is actually an early symptom of the earth returning to a natural planetary Ice Age?". She explain her question further as follows.

My dad is a chemical engineer, and is highly skeptical of global warming. He believes that the earth is actually undergoing a massive climate change, and that global warming is merely the early warning symptoms of a coming Ice Age, which we won't actually see for thousands of years, much like what killed the dinosaurs. I don't really know what to believe, since both arguments seem logical – what do you think?

I thought to  share this question on my blog and get answers and opinions from readers. Feel free to send your comments on dilantha[at]chempro[dot]org

Plants with GTL Technology in Oil & Gas Industry

What is GLT Technology?

"Gas to liquids (GTL) is a refinery process to convert natural gas or other gaseous hydrocarbons into longer-chain hydrocarbons such as gasoline or diesel fuel. Methane-rich gases are converted into liquid synthetic fuels either via direct conversion or via syngas as an intermediate, for example using the Fischer Tropsch or Mobil processes." - Wikipidea

How many GTL plants are there in this world? Is it a live technology used by industry?

Yes we can see many plants which are dedicated on GLT technology.

·        Pearl GTL in Qatar (the biggest in the world-140000 bpd) (

·        Bintulu, in Malaysia

·        Escravos in Nigeria

·        Oryx GTL in Qatar

·        Exxon Mobil GTL project (Still in planning phase and will take over the world biggest titile from Pearl in Qatar)

·        Two plants in planning stage in Australia

Chemical Engineering Thermodynamics

This book is written by Y.V.C. Rao

What is  Chemical Engineering Thermodynamics?

Chemical Engineering Thermodynamics deals with the basic concepts of thermodynamics and their applications. It not only introduces thermodynamic potentials as partial Legendre transforms of internal energy, but also deals with a number of advanced methods used for predicting thermodynamic properties, fugacity, fugacity coefficients and vapor-liquid equilibrium (VLE) data using generalized equations of state and the UNIFAC methods.

The book will serve as a core textbook for the course on chemical engineering thermodynamics for undergraduate students of chemical engineering and chemical technology, and also as a reference book for graduate students and practising engineers.

About Author

Prof. Y V C Rao obtained his B.Tech. degree in Chemical Engineering from Andhra University, Visakhapatnam, and his M.Tech. and Ph.D. degrees in Chemical Engineering from the Indian Institute of Technology, Kanpur. At IIT Kanpur, Prof. Rao has been teaching thermodynamics at all levels - core, undergraduate, professional and postgraduate - since 1973. He has published several research papers in national and international journals in the areas of thermodynamics, molecular energy transfer and shock waves, and presented several papers in national and international conferences.

High Speed Compressor design using computational fluid dynamics

computational fluid dynamics used to run multiple iterations of volute design on 15000 RPM high output air compressor using computational fluid design. Design comparison was key - showed better designs in a few days without prototypes.

This kind of simulation needs quite powerful computer. As example the person who created this simulation has used a 32bit XP workstation with a dual core 3.2 GHz processor and 3 GB (using unofficial 3 GB windows switch) of RAM.

According to the comments of the youtube video this model has two problems.

1. This radial turbine is backwards dumping the fluid in the counter-clockwise direction and then it want it to travel in a clock-wise direction - the air is being pushed in the wrong direction
2.The fluid is turning that huge corner and you have separation. The fast moving fluid is due to all the back-pressure rather than steady flow.
This  stator veins work because they redirect the air clockwise. Section-off this volute and flip this turbine.

Industrial Chemicals

Sulfuric Acid -- Probably the most common industrial acid. Used widely in mineral leaching and gas scrubbing (removing dangerous substances). Also used to neutralize alkaline substances.

Nitrogen – Most common inert substance used in industry. Used for everything from tank blanketing (so vapors don’t combine with oxygen to form explosive mixtures) to controlling reaction temperatures in exothermic reactions. Also widely used as a solid conveying gas carrier when air cannot be used due to explosion threats (ex/ fertilizers).

Oxygen – The ultimate oxidizer. Used in any application where the introduction of oxygen to the reaction mixture is necessary.

Ethylene – Probably the most popular industrial precursor to polymer manufacturing (ex/polyethylene).

Ammonia – Very popular scrubbing solvent to remove pollutants from fossil fuel combustion streams before they can be released to the atmosphere. Also a popular refrigerant.

Phosphoric Acid – Main use is in fertilizer production, other uses include soft drinks and other
food products.

Sodium Hydroxide – The most popular alkaline substance in industry. Widely used in dyes and
soap manufacturing. Also a good cleaning agent and can be used to neutralize acids. Also known
as lye.

Propylene – Another industrial polymer precursor (polypropylene).

Chlorine – Used in the manufacture of bleaching agents and titanium dioxide. Many of the bleaching agents based on chlorine are being replaced by hydrogen peroxide due to environmental restrictions placed on chlorine.

Sodium Carbonate – Most commonly known as soda ash, sodium carbonate is used in many cleaning agents and in glass making. Most soda ash is mined from trona ore, but it can be manufactured by reacting salt and sulfuric acid.

Sodium Silicate – Perhaps the most widely used industrial insulation.

Cyclohexane – While cyclohexane is a common organic solvent, its crowning achievement is it’s use as a reactant in the production of a nylon precursor (later).

Adipic Acid – This is the chemical that is made from cyclohexane and in turn is polymerized to nylon.
Nitrobenzene – Primary use is in the manufacture of aniline, which is in turn used as a rubber additive to prevent oxidation (antioxidant).

Butyraldehyde – Used to manufacture 2-ethylhexanol which is then used to manufacture hydraulic oils or synthetic lubricants.

Aluminum Sulfate – Widely used in the paper and wastewater treatment industries as a pH buffer.

Methyl tert-butyl ether – Also known as MTBE, it is most famous for its role as a gasoline additive (oxygenate). Due to its toxic affect on mammals, the EPA has been ordering a decrease in its use and an increase in the use of ethanol as a replacement.

Ethylene Dichloride – Nearly all ethylene dichloride produced is used to produce vinyl chloride
which is then polymerized to polyvinyl chloride (PVC).

Nitric Acid – Most common application is its reaction with ammonia to form the solid fertilizer ammonium nitrate.

Ammonium Nitrate – Probably the most widely used solid fertilizer

Benzene – The two largest uses for benzene are as reactants to produce ethylbenzene (used to produce styrene) and cumene (used to produce phenols). Also a very common organic solvent as well as a precursor to cyclohexane.

Urea – The majority of urea is used in fertilizer production. Some is also used in the manufacture of livestock feed.

Vinyl Chloride – As previously mentioned, this is the monomer form of polyvinyl chloride (PVC) which finds uses as a building material and other durable plastics.

Ethylbenzene – Used almost exclusivley as a reactant for the production of styrene

Styrene – Monomer form of polystyrene. Polystyrene is used in pure form and expanded. Styrene can also be used in mixed forms or copolymers such as ABS (acrylonitrile-butadienestyrene).

Methanol – Used as a reactant to make methyl tertbutyl ether (MTBE), formaldeyde, and acetic acid. Typically produced from synthesis gases, namely carbon monoxide and hydrogen.

Xylene – o-xylene (ortho) is used primarily to manufacture phthalic anhydride which is in turn
used to make a variety of plasticizers and polymers. p-xylene is used to manufacture terephthalic
acid, a polyester feedstock.

Formaldehyde – Commonly used as part of a copolymer series (Urea-formaldehyde resins) or
as another polymer additive used to bring out desired characteristics.

Terephthalic Acid – Almost exclusively used in the manufacture of polyethylene terephthalate
(PET) or polyester.

Ethylene Oxide – Majority of ethylene oxide is used to manufacture ethylene glycol which is
described later.

Hydrochloric Acid – Two main uses include production of other chemicals (by acting as a reactant or a catalyst) and the pickling of steel. Also widely used in the pharmaceutical industry.

Toluene – Used primarily to manufacture benzoic acid. Benzoic acid is a precursor to phenol (later), various dyes, and rubber products.

Cumene – Nearly all cumene produced is oxidized to cumene hydroperoxide, then cleaved (splitting a molecule) to form phenol and acetone.

Ethylene Gylcol – Most common use is as a reactant to form polyethylene terephthalate (PET).
Also used a primary ingredient in antifreeze.

Acetic Acid – Used primarily to manufacture vinyl acetate monomer (later) and acetic anhydride
which is used to manufacture cellulose acetate.

Phenol – Used to manufacture Bispenol-A (later) as well as phenolic resins and caprolacturm.
Propylene Oxide – Two primary uses include urethane polyether polyols (both flexible and rigid
foams) an propylene glycol which is used as a polymer additive as well as a common refrigerate.

Butadiene – Uses include styrene-butadiene rubber, polybutadiene, and other copolymers.

Carbon Black – Most common use is a rubber additive

Isobutylene – Most production is used to make butyl rubbers.

Potash – Used in agriculture as a crop fertilizer.

Acrylonitrile – Used as a reactant to form various copolymers along with acrylic fibers.

Vinyl Acetate – Monomer form a polyvinyl acetate, a common emulsion polymer and resin. PVA is the "sticky" agent in ordinary white glue.

Titanium Dioxide – Used as a white pigment for many products ranging from paints and
polymers to pharmaceuticals and food items. In short, if it’s white, it probably has titanium
dioxide in it.
Acetone – Used primarily to manufacture methyl methacrylate and Bisphenol-A

Bisphenol-A – Used as the main feedstock for polycarbonate resins and epoxy resins.

Sri Lanka Nuclear Energy Project for power generation and peaceful use

Sri Lanka's Atomic Energy Authority (AEA) is in the process of exploring the possibility of using nuclear energy for future power generation. Cabinet approval would be sought shortly to initiate a program for Nuclear Energy for Peaceful Use!!!

Nuclear fission energy (generating energy by splitting atoms) is usually generated with Uranium or Plutonium, but Thorium could be enriched to a fissile Uranium isotope by bombarding with neutrons. Thorium is also believed to be more abundant than Uranium. Australia and India are believed to have the largest Thorium deposits in the World. In Sri Lanka it is believed that there are enough Thorium deposits.

Tesoro Anacortes refinery fire

An explosion and fire at a Washington state oil refinery shook homes and shot flames into the night sky early Friday, killing three people and critically injuring four others.

The fire struck the Tesoro Corp. refinery in Anacortes, about 70 miles north of Seattle on Puget Sound, at about 12:30 a.m., the company said. The blaze occurred while maintenance work was being performed and was extinguished in about 90 minutes.

Four employees are hospitalized with major burns over the majority of their bodies. Susan Gregg-Hanson, a spokeswoman for Harborview Medical Center in Seattle, said they are two women, 29 and 36, and two men 34 and 41.

The Tesoro Anacortes refinery fire is the deadliest accident involving production at a U.S. refinery since the BP (BP.L) Texas City explosion on March 23, 2005 in which 15 workers were killed and 180 others injured.

4shared sharing network search – better than rapidshare and megaupload

We have to read many books and tutorial when we study subjects. I have seen many people try to find ebooks on internet but many of them not find what they are looking for. But personally when I need an ebook I just go to and conduct a file search. Many time result is positive and I can get good result. 4shared search engine is not very optimized one so people must be tactful when perform search. Do not use full title of the ebook at once. Most of the time try to use author name or part of book name. Use correct spellings because 4shared search engine is not like Google. It does not correct spellings

Day by day our solid waste is accumulated in uncontrolled dumping lands and create very unpleasant and potentially dangerous environment. These dumps are frequently allowed to burn - either deliberately, as a means of volume reduction, or accidentally. However it create more hazardous environment for workers and neighbors. Although there are many solutions to solid waste management due to lack of land in our small island I firmly believe that we need a rapid volume reductive solution as one of major option to our problem.

Incineration is one of ideal volume reductive solution on solid waste and we can see many developed countries including Luxembourg, the Netherlands, Germany and France use this technology for handling their waste. In Sri Lanka the only place where we can see a thermal treatment on solid waste is Holcim cement kiln which can be consider as a rotary incinerator. When I was an undergraduate student I had chance to visit Holcim cement manufacturing plant. In several days of spend at that manufacturing facility I observed that the kiln of Holcim is used as clinker production unit as well as a waste burning unit. Due to limited capacity of kiln large queues of medical waste, pharmaceutical waste and security printing waste are held at Holcim kiln every day. This implies the existing potential for properly controlled incineration facility for waste management in Sri Lanka. When we consider the number of open garbage dumps there are more potentials to explore for incineration facilities in Sri Lanka.

Incineration is very effective as it brings fast solution to waste management and it also can be used as Waste-To-Energy (WTE) or Energy-From-Waste (EFW) technology. A 250-tonne per day incinerator can generate about 6.5 megawatts of electricity daily. This amount is enough to power up approximately 2000 average houses.

In order to implement incineration as a solution we need in-depth analysis of fuel types, various designs such as moving grate, fixed grate, rotary-kiln, fluidised bed or specialized incinerators. Gaseous emissions such as dioxin, furan and green house gases and material separation is also very critical factors to consider as health concerns are the major drawbacks in implementing this technology. Above mentioned areas are critical to study for the efficiency and safety of the plant in order to manage the plant to meet triple bottom line sustainability.

Why Not ChemEng Success story

Whynotchemeng website which was implemented to inspire student and professionals on chemical engineering studies has achieved remarkable success. According to ICHEME analysis the website has been played a major role on conversion student on chemical engineering studies. I found that fact on TCETDAY magazine (2010 January). It launched promotional campaigns using social networks, google ads, youtube and many innovative ways to market their inspirational campaign.

Today young people spend considerable amount of their active time on internet and interactive web solutions such as blogs, social networks, social bookmarking … etc are wonderful way to give them a message.

IChemE had identified the potential and grab it. Congratulations ………

I am looking for more innovative campaigns in future.

Biodiesel from Used vegetable oil - via transesterification

Used vegetable oil can be turned into bio diesel via chemical reaction. This chemical conversion is called transesterification. [definition from wikipedia - In organic chemistry, transesterification is the process of exchanging the organic group R" of an ester with the organic group R' of an alcohol. These reactions are often catalyzed by the addition of an acid or base.]

We can produce biodiesel from used vegetable oil by a process involves reacting vegetable oils or animal fats catalytically with a short-chain aliphatic alcohols (typically methanol or ethanol).

This process can simplified then it will boost in small and medium scale business and even as home made biodiesel projects.

Following readings will helpful for more understanding.
