RECOVERY OF NATURAL GAS LIQUIDS AND PRODUCE LIQUIFIED PETROLEUM GAS FROM ASSOSIATED NATRAL GAS

Abstract

The major source of producing LPG in Sudan is from oil refining. The objective of this work is to Recover natural gas liquids and produce LPG from associated gas produced . The unit will consist of two parts: refrigeration unit, fractionation unit. The study is carried out following standard scientific approach of theoretical study and computer simulations. Associated gas flow rate, composition.. Material and energy balance are made for the process to determine the total energy and flow. A simulation for the process will be created in HYSYS V8.0, and studies are made to determined optimum operating pressures and temperatures. The optimum temperature and pressure is -110c and 1atm respectively.
