Removing organic sulfur compounds from higher hydrocarbons and gases, such as natural gas, containing water vapor involves adjusting content of gaseous organic sulfur

摘要

The content of gaseous organic sulfur compounds in the pure gas is adjusted to a residual concentration value of 5-20 mg/Nm3 by controlling the residence time in the adsorber bed by changing the charge height by a factor of 1.5-4. The remaining amount of sulfur compounds with the condensate produced in the regeneration step before or during condensation. Process for removing organic sulfur compounds from higher hydrocarbons and gases, such as natural gas, containing water vapor using solid adsorbents such as activated charcoal, molecular sieve, carbon molecular sieve, silica gel and KC pearls comprises feeding the crude gas mixture through a first adsorber bed filled with adsorbent to simultaneously adsorb the hydrocarbons and water vapor; driving off the hydrocarbons and water vapor using a partial stream of crude gas heated to regeneration temperature from a second previously charged adsorber bed; condensing from the desorption gas by cooling; and removing in a separator. The remaining regeneration gas is recycled to the crude gas stream.
