Sour Gas Degasification

The Term Sour Gas

refers to any natural gas or other gas that contains high levels of hydrogen sulfide (H2S). The H2S is typically naturally occurring and found in deposits of natural gas and when there are concentrations above 5.7 milligrams per cubic meter or 4 milligrams per cubic meter when tested under standard temperature and pressure. At these levels the industry classifies the gas as “Sour.” Of course there are variations to this classification dependent upon agency an organization.

A Sour gas is not to be confused with an acidic gas 

although one could be both a sour gas is strictly defined by having large quantities of hydrogen sulfide and is usually accompanied by having mercaptans which adds to the foul smell and odor. The term is often used in the oil refinery business and when gases contain sour gas the process to remove the hydrogen sulfide and mercaptans is referred to as “Sweetening”. The most common method to “sweeten” and remove the sour gas is by processing the gas through an “amine process” which removes the harmful gas.

Decreasing Amine Consumption

Many times, process systems will fail to recognize when the Degasification or Decarbonation system is failing or under performing. One critical signal that can be used as a verification is when a process also utilizes Amine in the downstream treatment the consumption rate will increase which can drastically increase operational cost. When a packed column tower begins to fail it can be associated with fouled media, a failed distribution system, plugged intake vents, or a failed or failing blower. Often in high noise environments it is difficult to notice if a belt has broken or slipped on a Decarbonation blower and the control room may still be showing that the blower motor is operational.
