Chemical Engineering forum plus social network

I created a social network (long time ago) for chemical engineers to join and discuss current topics such as professional problems, jobs information, scholarship data ... etc. This is a professional social network which allow to share what we know with other chemical engineers. You can join with this forum and invite your friends to join with it.

The chemical engineering forum can be used to discuss many topics. Chat room can be used to discuss professional topics. Blogs can be used to publish your research work and professional works.

Drum Dryer

It is a dryer which uses a surface of internally heated revolving drum to dry substances which are undergone drying. This is the basic introduction to the drum dryer. But drum dryers can be classified into various sub categories according to number of drums, feeding method, internal pressure … etc.

Types of drum dryers [According to the drum design and pressure]

· Double drum dryers

· Twin drum dryers

· Vacuum double drum dryers

· Single drum dryers

There are several feed methods and we can classified drum dryers according to them also.

Pan feed

Dip feed

Splash feed

Design Temperature for drum dryer

This value is also very important in selecting fabrication material for dryer. The drum, knife, spreader are the vulnerable component to high temperature. So design temperature is very much valuable data when those components are being designed. The strength of metals decreases when increasing temperature. Design stress is evaluated should be taken as the maximum temperature of the material with due allowances for any uncertainty. That is why design temperature value is very much critical in design stage. Normally the design temperature for pressure vessel is taken as more than 25% of operating range.
Therefore
Design temperature = Maximum operating temperature + 25% operating temperature

Chemical Engineering Rules of thumbs – Conveyers [Screw, Belt , Bucket , Drag Type, Pneumatic]


Screw Conveyers

Screw Conveyers are suitable for sticky and abrasive solids with up inclined angle up to 200. Screw Conveyers. The conveying distance is normally up to 150 ft. A 12 in. diameter screw conveyer can transport solids at a rate of 1000-3000 cuft/hr with 40-60 rpm speed.

Belt Conveyers

Belt Conveyers are suitable for high capacity and long distance such as one or more miles with up inclined angle up to 300 . As example a 24 in. wide belt can use to convey material at 3000 cuft/hr with speed of 100 ft/min. Belt conveyers use low power when comparing to others.

Bucket Conveyers (Elevators)

Bucket Conveyers are suitable for vertical transport of sticky and abrasive materials. As example with 20 X 20 in. bucket, 1000 cuft/hr rate can be achieved at a rate of 100 ft/min.

Drag Type Conveyers (Redler)

Drag Type Conveyers are suitable for short distance transport in any direction and it is completely enclosed conveying method. Unit sizes are change from 3 in. square to 19 in. square and speed can be vary from 30 ft/min to 250 ft/min. Power requirements are comparatively high.

Pneumatic Conveyers

Pneumatic Conveyers are suitable for high capacity and short distance. Vacuum or low pressure is employed (6-12 psig) with 35 – 120 ft/sec range of air velocities depending on material and pressure.

Site Selection for Chemical Process plant using Google Earth Pro [+ factors considered when site selection ]


Site selection for chemical process plant is one of the major steps in plant design process. Major steps in plant design process are Process Design and Safety, Layout, process control and instrumentation, energy and utility balance, manpower requirement, cost estimation … etc.

Many factors must be considered when site selection process carried out

Available transportation methods [if rail roads, channels, harbor facilities or air port are accessible, great potentials is there to invest]*

Sources of raw material #

Cost of raw material

Prospective markets for products #

Corporation loan term planning [chemical leasing, other plant’s waste as raw material or utility …. etc]

Water source-quality and quantity #

Climatic conditions [long term weather patterns, new pattern in weather due to climate change]

Pollution requirements (Waste disposal regulations; regulations change from countries to countries as well as in local government wise)

Utilities-cost, quantity and reliability; fuel-costs, reliability and availability

Amount of site preparation necessary [geological survey] #

Construction costs [cost of construction material, technology, labour force, availability of third party contractors]

Operating labor

Taxes

Living conditions

Expansion possibilities [land, regulations… etc]

Google Earth is wonderful internet based software tool which brings basically satellite images of earth onto your desktop. * mark represent factors which can be totally found using Google earth pro. # mark represent factors which can be found using Google earth pro but you must also refer other resources. Google earth pro can be used as a screening tool for available sites. You can filter out best locations based on this tool and next plan actual visits to sites. Do you have any doubts on Google earth pro images, see following sample image.

Small is beautiful

When we assign to do things we think about very big things, but do you think that you can do big change with small innovation. Emily Cummins, a management student of University of Leeds had been coming up with a solution which will help to enhance underdeveloped countries quality of life. She had come up with Solar Powered Refrigerator.


Emily Cummins with her Solar Powered Fridge


Two Namibia children feel happy about her innovation

Technology behind this innovation; it contains two aluminum cylinders. One has installed in other and the gap between two cylinder has filled with sheep's wool. Water will be added in to the layer of wool and with warm temperature water will evaporate while absorbing heat from inside. She had come up with good design, that is the importance.

University of Leeds featured this on their Alumni Magazine 2007.

Free Electric Cars from Project Better Place


A project called project better place suggest to popularize electric cars with new and attractive strategy. You will be wonder about it. They are going to give people a electric car free of charge and only charge of batteries and other related service. Better to read about it.

We Can Solve It



Al Gore's latest 300 billion USDs ad campaign, with a patriotic angle "by solving the climate crisis, we are honoring an American tradition". The initial step has taken now, www.wecansolveit.org

But I do not think America itself can fight with Climate crisis alone, because it is global issues and there are several nations who have great responsibilities on climate crisis; China, India, .... etc. We need to think as a global citizens not with narrow nationalities. If we want to fight with global issues such as climate crisis, poverty, war, terrorism, gender issues, drug trafficking, .... etc we have to join our hands.

However Al Gore you are great! Something is better than nothing. Good initiative! You have nothing to win, because the best prize, you have already won. I think your next achievement will be solving climate crisis forever.

Solar Powered Student Centre







As an practical approch to renwable energy engineering subject we started a solar powered Student Centre in our department. We already have a student centre and we hope to power it with solar power.

India's present strength in Chemical Industry

India's chemical industry which began in 1930 has tremendously developed and now they contribute to national economy with 150 billion $ per annum. Now they are 3rd in Asia and 13th of world.

I forgot the source now but I think it should be TCETODAY or CPE.

Anyhow they have becoming a leader. What about us?
