A stripper is one of the standard columns that is available in Hysys. If you have problems setting it up, consult their manuals or call tech services. They are very helpful and will work directly with you to set up your problem.
One thing to consider with the temperature transmitter down stream of the control valve is that once the valve closes, the transmitter is isolated from the source of high temperature. You need upstream temperature indication also to ensure that it is ok to reopen the valve and a manual reset on...
This problem is similar to the melting of permafrost in the Arctic. During the summer, the permafrost thaws only a couple of feet. Of course, the air temperature is not 100F, but I think 17 feet is a long distance to thaw and it should take quite a whil-- months perhaps.
From my expenience working with engineering contractors, usually the client (particularly if it is a major oil and gas company) will specify the process simulation package to use. They want you to use the one that they use. This way it is easy for them to check/verify the work that you are...
This respoonse is kind of late, but I will answer dtai's questions as they stand in a general sense:
1. The amount of heavy hydrocarbon separated in the knockout vessel depends on the amount of liquid in the incoming stream and the design (size and type in internals) of the vessel. If there is...
I second TrevorP's comment:
DO NOT design a safety system that requires human intervention for it to operate properly, i.e. switching rupture discs depending on mode of operation. Design the pressure relief system for the worst case scenario. Then use pressure controls or dump valves to limit...
I don't see any particular problem with this design. It will work although you might want to add another tray or two to the column. The simulation assumes a theoretical tray for the reboiler that is not accounted for. Also, the actual reboiler duty may be slightly higher (but not much) than...
