Small pressure difference big temperature drop craft in gas plant application studying

Yulin gas plant uses the propane compression circulation refrigeration,th e low temperature separation method,the propane compressor design shaping is big,the energy consumption is high.The discussion replaces the propane refrigeration system with the throttle valve,the small differential pressure has the small temperature drop,has the big temperature drop through the big area cold box,achieved the low temperature separation condition,in the gas conditioning craft system movement process,at the right moment suspends shipment the propane refrigeration system,enhances the craft movement economic efficiency.
