This article presents a low-tonnage oil and gas processing plant (OGPP-20), its main process equipment and the operating principle. Three methods for producing a liquefied propane-butane fraction and designs of the equipment for its implementing are proposed: compression and condensation, compression and further throttling which allows the compressed gas cool to lower temperatures and rectification. The results of numerical studies of the methods of producing liquefied propane-butane in the Aspen HYSYS program for the thermodynamic model of Peng–Robinson substantiate the method of obtaining the liquefied propane-butane fraction and its design.
