7、 To meet therequirements better,it is necessary tothoroughly understand and master the difference between thegas storageconstruction and the reservoir development construcnulltion becauseof theworking conditions, inside characteristics andoutsiderequirements of thegas storage. With the experience of

The results show with the

13、ects inthe operation process and the autonullcontrol system. Aiming tothe realsituation of the plant,thefollowingmeasures for techninullcalrehabilitation are taken. The flow process of light oil fromliquid gas tower to the crude oil stable device is extended. Thelight components are recovered second
14、ary. The recovering ratioof the plant is improved. The foresidestructure of the propaneevaporator is rehabilitated. Somecopper tubes to guide the feedmaterial are added. The problems of jelly and stoppage in thepropane evaporator are solved. The working parameters of thepropane compressor are analyz
15、ed, and its autonullcontrol project ofthe replenish pressure is renulldesigned. The temperature autonullcontrol loopof thedenullpropanetower is added. After therehabilnullitation,the recovering ratio of the plant increases from 71.4%to 85.2%. Also,the output of the liquefied gas increases. Thedenull
16、freezing cycle of thepropaneevaporator increases from 8 d to24 d. The refrigeration temperature of thesystem is quite stanullble. The safety of thesystem is improved. And obvious benefitsare achieved.null null SUBJECT HEADINGS: Light hydrocarbon recoveringplant, Technical rehabilitation, Workmanship
