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.
