NOVELTY - Raw natural gas is purified by depositing raw natural gas to an aqueous amine-based contaminant absorption column for first stripping. The contaminants undergo second stripping through a stripper using a second quantum of the sweet gas as the stripping gas. The stripper waste gas is conveyed to a process heater.    USE - For the purification of acid gas streams with BTEX contaminants.    ADVANTAGE - The method is rapid, versatile, ecologically compatible, energy conserving, efficient, inexpensive, and does not require highly skilled personnel to install, operate and maintain.    DETAILED DESCRIPTION - Purification of raw natural gas comprises collecting a quantum of raw material into a raw natural gas intake conduit (10). The quantum of raw natural gas is deposited to an aqueous amine-based natural gas contaminant absorption column (12), for first stripping portions of hydrogen sulfide (H2S), carbon dioxide (CO2), benzene-ethylbenzene-toluene-xylene (BTEX), and volatile organic compounds (VOC) constituents from the raw natural gas. A first portion of sweet gas produced by the first stripping is delivered for conveyance to a purified gas manifold (16). The contaminated aqueous amine (18) which carries the constituents are collected in an amine flash vessel (22). The contaminants from the contaminated aqueous amine undergo second stripping through a BTEX stripper (28). The second stripping includes introduction of a second quantum of the sweet gas as the stripping gas, to the BTEX stripper. Lean amine is injected through a lean amine input (33), to the upper portion of the BTEX stripper. The lean amine interacts with the BTEX stripper waste gas as produced from the second measure of the sweet gas. Introduction of lean amine absorbs CO2 from the stripper waste gas, rendering the BTEX waste gas more suitable as a combustible fuel. The produced BTEX stripper waste gas is conveyed from the stripper to a process heater. The process heater (34) provides heat for heat-requiring processes occurring through operation of a natural gas processing facility. The stripper waste gas serves as the combustible fuel for the process heater. An INDEPENDENT CLAIM is also included for a natural gas processing facility comprising a raw natural gas intake conduit; an aqueous amine-based natural gas contaminant absorption column for receiving the raw natural gas from the conduit; a purified gas manifold for delivering a portion of sweet gas produced by the first stripping of the constituents from the raw natural gas, from the processing facility to storage and transportation facilities; a flash vessel attached to the aqueous amine-based natural gas contaminant absorption column, for collecting contaminated aqueous amine which carries the constituents as absorbed from the raw natural gas; a BTEX stripper for receiving the contaminated aqueous amine from the flash vessel, for second stripping of the contaminants from the contaminated aqueous amine; a stripping gas input (30) attached with the aqueous amine-based natural gas contaminant absorption column and with the BTEX stripper, for conveying a second portion of the sweet gas to the BTEX stripper; a lean amine input for injecting lean amine into the upper portion of the BTEX stripper; a stripper waste gas manifold (32) for collecting and conveying BTEX stripper waste gas from the BTEX stripper after exposure to the lean amine; and a process heater for providing heat for heat-requiring processes occurring through operation of the natural gas processing facility. The process heater operates through combustion of combustible fuel, and is connected with the stripper waste gas manifold for receiving all the BTEX stripper waste gas produced.
