Due to increased pressure on existing SRU`s capacity resulting from sourer crudes processed in Slovnaft refinery, various options for increasing acid gases processing capacity were investigated.
Basically, there are three conventional ways to increase SRU capacity via building a new SRU, revamping existing SRU or oxygen enrichment. However, Slovnaft went for unconventional option via partnering with fertilizer company which will invest into new SWAATS unit developed to process sour water stripper gas by converting the ammonia and hydrogen sulphide to ammonium thiosulphate (ATS) and thus debottlenecking existing SRU for more amine acid gases.
The presentation will review SRU capacity debottlenecking options and present economic, operational and HSE benefits of producing liquid fertilizer ATS at the refinery site with a partner company.
