LO-CAT Sweetens 76,800 Scfm Of Gas At County Cork, Ireland, Refinery
Under new directives to reduce sulfur in diesel and gasoline, European refineries are revising both their fuel production processes and their downstream desulfurization strategies. At the Irish Refining plc refinery near Whitegate Middleton, County Cork, Ireland, a LO-CAT II H2S Oxidation System was selected for sulfur recovery based on the following criteria: 3 to 1 gas flowrate turndown, 3 to 1 H2S concentration turndown, H2S outlet concentration less than or equal to 10 ppmv, minimal operator attention, sulfur production suitable for agricultural use, and a reliable, proven process.
The LO-CAT II unit was custom designed to sweeten 6,800 scfm of gas at 70 psig, containing 1.8 vol% H2S and 80 vol% H2. The treated gas contains less than 10 ppmv H2S, allowing this offgas to be burned as fuel.
