Qatar Liquefied Gas Company Limited (Qatargas) has executed a major debottlenecking of its existing facilities at Qatargas 1 in order to maintain the LNG production, while coping with increased levels of H2S and CO2 in the inlet feed gas streams.

As part of this plateau maintenance project (PMP), a new pretreatment acid gas removal unit (AGRU), upstream of the existing gas sweetening facilities, an additional sulphur recovery unit (SRU) and a tail gas treatment unit (TGTU) have been added to existing facilities.
