Call for a Research Fellow in Process Simulation


Available position

A research fellowship is offered to join the research program Advanced concepts and process schemes for CO2 free fluidised and entrained bed co-gasification of coals, financed by the Research Fund for Coal and Steel of the European Commission for the period 2010-2013. This international project aims at integrating gasification schemes for the co-gasification of coal, biomass and wastes with processes for CO2 separation and capture. The project will be carried out by nine research units of European universities, research centres and companies

The research fellow will be responsible for flowsheet model development of process schemes, including entrained flow gasification, water gas shift reaction, CO2 capture and power generation. The program will cover also heat integration and economic evaluation of the process.


Requirements

A Ph.D. in Chemical Engineering or Process Engineering with extensive experience (preferably two years) using process simulation software (Aspen Plus, Hysys, ProII, gProms etc.). Good level of knowledge and experience in programming language are highly appreciated

Duration and scholarship

One year (possible one year extension). 22000 EUR/year net salary. Considering the cost of living in Salerno, the scholarship is adequate for covering all the living expenses for one person.


Starting date

August 2011
