Abstract

Natural gas containing an acid gas component is treated in a liquid absorption stage to remove the acid gas, and in a solid adsorption stage to separate unadsorbed light hydrocarbons (e.g. methane and ethane) from adsorbed heavy hydrocarbons (e.g. propane and butane). The hydrocarbon fractions may afterwards be recombined. In one embodiment, the heavier hydrocarbons are first separated from the acid natural gas by adsorption, the residual gas being then treated with liquid absorbent to remove the acid gas from the lighter hydrocarbons. In a second embodiment, the acid natural gas is first treated with liquid absorbent to absorb heavier hydrocarbons and acid gas and to leave the lighter hydrocarbons as the residual gas stream. The gas evolved during regeneration of the liquid absorbent is treated with the solid adsorbent to adsorb the heavier hydrocarbons from the acid gas for subsequent recovery. Specified adsorbents include activated alumina, silica gel and charcoal. Specified liquid adsorbents include polybasic aliphatic alcohols, their ethers, esters and ether esters. The solid adsorbent is desorbed and regenerated by hot light hydrocarbons from which acid gas has been removed while the liquid absorbent is regenerated by heating and flash pressure reduction. Detailed flow diagrams illustrating both embodiments, and employing twin adsorption columns, one being "on stream" and the other being regenerated, are provided.
