Angola LNG Plant
Angola LNG is a liquid natural gas (LNG) facility in Soyo, Angola. Technical features The Angola LNG plant is a single train facility with production capacity of 5.2 million tonnes per year. The plant uses ConocoPhillips' proprietary natural gas liquefaction technology (Optimized CascadeSM Process). In addition to LNG, it also produces propane, butane and condensate. The plant is supplied from offshore gas fields on blocks 14, 15, 17 and 18, and from non-associated gas fields Quiluma, Atum, Polvo and Enguia. The LNG project is presented as environmentally friendly by its designers, because most of its feedstock will consist of associated gas produced in association with crude oil in offshore field, that is currently flared. However, while LNG production is more environmentally friendly than flaring, liquefaction is also a highly energy-intensive process and a significant percentage of the gas must be burned to generate the energy to cool the rest. The plant was constructe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Liquid Natural Gas
Liquefied natural gas (LNG) is natural gas (predominantly methane, CH4, with some mixture of ethane, C2H6) that has been cooled down to liquid form for ease and safety of non-pressurized storage or transport. It takes up about 1/600th the volume of natural gas in the gaseous state (at standard conditions for temperature and pressure). LNG is odorless, colorless, non-toxic and non-corrosive. Hazards include flammability after vaporization into a gaseous state, freezing and asphyxia. The liquefaction process involves removal of certain components, such as dust, acid gases, helium, water, and heavy hydrocarbons, which could cause difficulty downstream. The natural gas is then condensed into a liquid at close to atmospheric pressure by cooling it to approximately ; maximum transport pressure is set at around (gauge pressure), which is about one-fourth times atmospheric pressure at sea level. The gas extracted from underground hydrocarbon deposits contains a varying mix of hy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
