Abstract

Natural gas liquid is one of the products from petroleum reservoir. Natural gas liquid or NGL is one of the components of natural gas that are liquid at surface in field facilities or in gas-processing plants (Schlumberger Oilfield Glossary website, 2012). The compositions of this substance are propane, butane, pentane, hexane and heptanes, but not methane and ethane, since these hydrocarbons need refrigeration to be liquefied. NGL can be separated to several classes such as low (condensate), intermediate (natural gasoline) and high (liquefied petroleum gas) vapor pressure based on their vapor pressure The best operating condition (temperature and pressure) need to be study and analyze in order to produce highest composition of liquid in natural gas liquid. Phase diagram of natural gas component give us the hint and reference how to manipulated and vary the operating conditions. From the phase diagram, the composition of liquid at certain temperature and pressure can be calculated even though there contain more than two components in the mixture. Information such as Cricondenbar, Cricondentherm, Critical Point, bubble point curve and dew point curve of natural gas give us a lot of information to manipulate the operating condition. A simulation of model process of natural gas liquid must be done to get the best operating conditions of production natural gas liquid (NGL). This simulation can be done using HYSYS. From the simulation, we compare from different operating condition with the composition of liquid and CO2 in the substance.
