Natural Gas

The goal of processing is to separate petroleum into marketable commodities in the most cost effective way. As well, with concerns about sour gas and carbon dioxide from the natural gas, the environmental impact from processing gas is also a challenge. The method to produce the natural gas involves steaming out the undesirable elements in a multiple step system. The gas is sent to a separation unit that takes out the liquid hydrocarbons, water, and solids. The gas continues on to be treated with acid, removing the carbon dioxide. Two chemicals come out of this process: the sweet gas and the hydrogen sulphid. The hydrogen sulphid is recoverable, and can be used in the making of fertilizer, pulp and paper, steel, pharmaceuticals, and other products. The sweet gas is then dehydrated and becomes dry gas. The gas is then ready to be processed into marketable items: methane, liquid hydrocarbons (Propane and Butane), and hydrogen.
