Kuwait’s state owned Kuwait Oil Company (KOC) has issued a tender for companies to bid on construction of the second phase of its gas sweetening facility at booster station BS 171 in West Kuwait. Thirty-two companies have been pre-qualified to bid for the $390 million engineering procurement and construction (EPC) contract for the project. Phase II will involve the construction of two processing trains, each with a capacity to produce 60 million scf/d of sales gas from sour gas with an H2S content of 4%. Sulphur recovery from the project will come from two separate 100 t/d trains with a total capacity of 65,000 t/a of molten sulphur.

Chevron says that its 50% owned affiliate Tengizchevroil LLP (TCO) has started oil production at its Future Growth Project (FGP) located at the Tengiz oil field in Kazakhstan. FGP is the third processing plant in operation at the Tengiz oil field, which expands sour gas injection capability and is expected to ramp up output to 1 million bbl/d. This milestone follows the completion of the Wellhead Pressure Management Project (WPMP) in 2024, which is designed to optimise the field and processing plants. The FGP expansion aims to increase crude oil production by 260,000 bbl/d at full capacity.

The Abu Dhabi National Oil Company (ADNOC) has launched a tender for the expansion of offshore gas production at its Satah Al Razboot (SARB) field, part of the Emirate’s huge Ghasha concession. The scope of work will include the engineering, procurement, and construction (EPC) of at least two wellhead platforms with multiple related facilities and the installation of a 24” subsea gas pipeline to new inlet facilities at Das Island. The project will also include brownfield tie-ins at Al Qatia, Bu Sikeen Islands, Das and Zirku and Arzanah Islands.

TotalEnergies and its partners Basra Oil Company and QatarEnergy have begun construction works at ArtawiGas25, a processing facility for the associated gas from the Ratawi field, located in the Basra region. The facility, part of the Gas Growth Integrated Project (GGIP), represents an investment of around $250 million and will process 50 million scf/d of gas which would previously have been flared. The gas will supply local power plants, covering the demand of approximately 200,000 households in the Basra region. The GGIP project is a $10 billion project designed to enhance the development of Iraq’s natural resources and improve the country’s electricity supply. It includes a large-scale gas processing plant, with a first phase of 300 million scf/d that will recover gas being flared on three oil fields and supply gas to 1.5 GW of power generation capacity.

Russian media reports suggest that a large scale Ukrainian drone strike on February 3rd attacked a number of oil and gas processing facilities, including Gazprom’s Astrakhan Gas Processing Plant. Video of the site showing fires burning were posted to social media. Astrakhan is one of the largest sulphur producing sites in Russia, with an output of around 3.5 million t/a in 2024. The Moscow Times reported that production had been shut down at the site, and would likely remain so for “several months”.

Building on the success of its previous conferences, SulGas Mumbai 2025 brought together 154 sulphur and gas treating stakeholders, representing 68 companies for its 7th technical forum in the Indian subcontinent. We report on some of the key topics on the agenda.

As the oil and gas industry focus on new requirements for CO2 recovery, cryogenic processes come under the spotlight. Mahin Rameshni and Stephen Santo of RATE USA discuss the importance of cryogenic processes in acid gas sweetening. Liquefied H2 S and CO2 reinjection is proposed as a cost effective alternative to large sulphur plants.

China’s acid production continues to grow as new smelters come on-stream. But high domestic demand from phosphate production as export restrictions are lifted and a shortage of copper concentrate may limit the potential for acid exports.

Refinery sour water strippers are an often overlooked resource of low GWP ammonia. Martin A. Taylor and Charles L. Kimtantas of Bechtel Energy Technologies and Solutions, Inc. (BETS) show the results of a study on reusing an existing SWS as one of the major systems in a SWSPlus unit for the recovery of ammonia for sale. Relative cost factors will compare a complete SWSPlus unit versus reusing an existing SWS.
