Pumped out of deep wells and when people are trying to find oil they dig up natural gas instead. They storage it and then they use tankers to bring them across the seas or oceans
How Is Natural Gas Recovered From The Ground?
hi
The raw gas is then pipelined to a gas processing plant where the initial purification is usually the removal of acid gases (hydrogen sulfide and carbon dioxide). There are many processes that are available for that purpose as shown in the flow diagram, but amine treating is the process that was historically used. However, due to a range of performance and environmental constraints of the amine process, a newer technology based on the use of polymeric membranes to separate the carbon dioxide and hydrogen sulfide from the natural gas stream has gained increasing acceptance.
