Natural Gas Sweetening Natural gas may contain high quantities of hydrogen sulfide H2S and/or carbon dioxide CO2. The presence of these compounds renders the gas a sour gas. This is specially because sulfur has such negative effects on the quality of the produced gas, that the concentration of both components have to be reduced from […]
Introduction to LNG Processes The refrigeration and liquefaction sections of any LNG project are very costly items of equipment. A number of cycles have been developed to achieve the low temperatures required. Brief descriptions of a small number of process routes will be give. Some twelve countries were operating by 2003. The cycles employed are the […]
A natural gas is called sweet gas if it has no sour components such as H2S, CO2, mercaptans, but is almost exclusively composed of methane, low amounts of ethane, propane, inert gases (N2) and traces of heavier hydrocarbons. It is generally saturated in water at reservoir temperature and pressure. A natural gas is usually defined as […]
