Gas separators are gas scrubbing units applicable for purifying gas and gas-condensate wells vapor from condensed droplets, hydrocarbon, solids or other impurities present. The impurities hamper gas transportation and lead to pipeline corrosion, obstruction (full or partial) of gas wells and field equipment due to formation of hydrate or ice cork. Application of gas separators is an effective solution to these problems, increasing economic efficiency of natural gas production systems.
