Natural gas pipelines often contain significant amounts of liquids that can interfere with the proper operation of the pipeline and related equipment such as compressors, regulators, filters, meters and valves. The liquids normally found include hydrocarbon condensations, lubrication oils, produced water, and chemicals used in production, treatment, compression or dehydration of the gas. The liquid to gas ratio in gas production pipelines can be as high as 100 Bbls/MMSCF of gas. When gas and liquid flows in hilly terrain, the liquids tend to accumulate in the low spots or valleys of the pipeline. A slug catcher is designed to allow expansion of gas stream to slow velocity and provide a settling area for and retention of liquids carried with the produced gas flow. They must have sufficient volume to contain the liquid and allow passage of gas flow without re-entrainment of the liquid in the out flowing stream. Surface Equipment Corporation has the design experience to adequately size and match the performance needs of slug removal equipment.
