Concentrated Photovoltaic Systems: The Solution To Making PV Solar Competitive

I got this email invitation from one of my subscription. I thought to share it with you. 

They invite you to attend IHS The Energy Daily's newest webinar Concentrated Photovoltaic Systems: The Solution To Making PV Solar Competitive on February 15, 2011 at 1:30 p.m. ET.

The topics of discussion for this 90-minute interactive webinar include:
  • What is the optimum concentration level for solar cells?
  • Are terrestrial cells the same as space solar cells?
  • Are there standard cell sizes or standard configurations?
  • What types of CPV solar cells are commercially available?
  • What is the maximum temperature a concentrator solar cell can handle?
  • Is active cooling of solar cells required?
  • What kinds of optics are best for concentrating light on your cells?
  • Does uniformity of light make a difference in terms of cell performance?
  • What is the highest-efficiency cell that has been produced?
  • And your questions!

Must Additional Qualifications for better Chemical Engineering Carrier

We all know for any field of carrier there is too much competition for entering as a professional. Entrance exams, workshops and series of interviews; these are not new things to job seekers these days. When we are in selection process for a vacancy it is common we are fighting with people with same qualification most of time. Therefore, additional qualifications will play vital role in every selection process; especially to be come out of bunch of same qualified personal. What are to most seek additional qualifications of chemical engineering carrier these days?

Occupational Safety and Health 

This does not mean that you have to follow up a diploma or degree program on this area. However, workshops, seminars or even short-term program will be more than enough with your basic qualification.

Certification in First Aid 

We know as chemical engineers frequently deal with hazardous processes, it will be a value addition if you equipped with first aid skills. Do not think this as a huge burden of your study program. I think Red Cross Society provides nice short-term program on first aid and they even issue certificate, which is valid for couple of years.

Experience in CAD applications 

If you are familiar with 2D – 3D computer aided design tools, it will be more advantage for you. Do not ever think that you need certificates to prove these skills. If you have used them in your study program especially in design project; add it up with your CV. Highlight your skill with computer aided programs.

Bio-methane as a transport fuel

"Bio-methane as a transport fuel” project has been started since 2007 by Department of Chemical & Process Engineering at University of Moratuwa, Sri Lanka. This project was funded by Ministry of Science and Technology, Sri Lanka. The main objective of this research project is to demonstrate the feasibility of using biogas as a transport fuel.

Project was initiated in the year of 2007 and construction of the pilot plant was completed in the middle of 2009 and thereafter development activities were started. In this research project, anaerobic co-digestion process technology is used for biogas production and canteen food waste was the main substrate with co-substrates of water hyacinth and Gliricidia. Produced biogas was upgraded to Synthetic Natural Gas (SNG) by scrubbing and absorption processes implemented by the biogas research team in Department of Chemical & Process Engineering at University of Moratuwa.

In the process, firstly, separate the organic fraction of canteen food waste from canteen waste and crushed in a crusher mixed with co-substrate in the presence of high concentration of water. Then it pumps to continuous system tank reactor (CSTR) which is operating in anaerobic conditions. Biogas is producing in this reactor and effluent is used as an organic fertilizer. Produced biogas was upgraded to Synthetic Natural Gas (SNG) by removing CO2 in scrubbing process and removing moisture in absorption process. The upgraded Synthetic Natural Gas (SNG) was compressed into cylinders and used as a transport fuel.

The Biogas research team in department of Chemical & Process Engineering has been proved that Synthetic Natural Gas (SNG) can used for ignite the engine as well as transport by conducting several test runs using a three wheeler. Demonstration nursery in the University of Moratuwa were resulted in remarkable fruits and vegetables from the pilot plant effluent used as a liquid organic fertilizer.
