World GTL Trinidad Limited (In Receivership)2008.09-2010.05(2 years)Performed simulation of the amine carbon dioxide removal system using E-NRTL Improved plant Aspen HYSYS simulation by changing Gibbs reactors to equilibrium reactors to better represent the APR-SMR setup where the ATEs were changed to better reflect the expected methane conversion and WGS reactions Supervised pilot plant reactor testing activities to ensure testing objectives were completed at Pittsburgh Applied Research Centre in an oil cooled reactor. This also included participating in the loading and unloading of catalyst and troubleshooting of reactor problems. Testing then conducted at Emerging fuels technology in a steam cooled reactor Simulated the fuel gas system for the plant to determine demand and evaluated the effect of using fuel gas with high hydrogen content on the heaters (hydrogen from the membrane unit) Participated in process equipment inspection towards mechanical completion and turnover this included amine regenerator column and contactor, diesel and naphtha columns and Fischer-Tropsch reactor. Additionally assisted in the loading of column packing
