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...
I need some guidelines to make specification for a distillation column.
The vessel shall be designed according to ASME VIII div. 2.
Design pressure is 8 bar and design temperature is 250 deg.C, , material is CS.
As a consequence of a up set condition, the vessel could be filled up with liquid...
Hi all,
I design a temperature controller for a heat exchanger. A by-pass line around one side is used to control the outlet temperature. The size of the main line and bypass line is large (14"), such as a three-way valve is not desired. A layout with two butterfly valves is suggested. But...
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...
I 'm interesting to know what is the maximal temperature a high head pump can work ?
The pumping fluid is gas oil at few bars on suction side. Discharge pressure is 50 to 100 bar. The question is raised when I want to recover as much as possible heat from the low pressure section of the plant...
