    Crew compressor as make-up compressor

    In hydrotreating process, the make-up hydrogen is supplied by a make-up compressor with discharge pressure in the range 50 to 90 bar. Suction pressure is around 20 bar. Gas purity is 90% H2 or higher. All make-up compressors, I have seen are of reciprocating type with a stand-by machine. The...

    Replace DEA with MDEA to increase capacity

    I'm working in a project to find a way to increase the capacity of an amine absorber. The amine absorber is installed in a diesel HDS unit to remove H2S from the recycle gas. In the future, sulphur in the feed will increase by 50% and the H2S amount to be removed is expected 50% higher. The...
