H2S Removal From Natural Gas: SourSep™


Sour gas is an inconvenience right from the wellhead. Membranes can be used for bulk removal of H2S upstream and combined with downstream facilities to polish the treated gas to meet pipeline specs. Upstream bulk removal can be combined with re-injection of the H2S to unload downstream sweetening and sulfur production facilities.

Membrane Solution

MTR’s SourSep™ systems bulk remove H2S from pressurized sour gas in a simple single stage process. Bulk removal (>75%) will generate a very sour low pressure permeate gas which can be re-injected. The unit is simple, has no moving parts, no absorbents or adsorbents and processes only gas. No liquids or solids are used or produced. The incoming high pressure sour stream is split into a moderately sweetened high pressure product stream and a low pressure H2S rich reject stream.

SourSep™ bulk H2S removal can be combined with reinjection or (ii) other direct H2S to S conversion processes H2S disposal. Moderately sweetened product gas can be polished using (iii) lightly loaded conventional amine units with existing Claus facilities.
