Indonesian nickel miner Merdeka Battery Materials (MBMA) and partners have signed definitive agreements to construct a high-pressure acid leach (HPAL) plant on the Morowali industrial park, Sulawesi. The unit will have a nameplate capacity of 90,000 t/a of contained nickel in mixed hydroxide precipitate (MHP). PT Sulawesi Nickel Cobalt (SLNC) will construct and operate the plant adjacent to the existing HPAL plant operated by PT Huayue Nickel Cobalt (HNC). SLNC will source and process laterite nickel ore through a 20 year commercial agreement with MBMA's SCM mine, starting from the commissioning date. An ore preparation plant will be built at the SCM mine to enable ore transportation via pipeline to the SLNC processing plant at IMIP. The total combined investment for constructing SLNC (including interest incurred during construction) is expected to be approximately $1.8 billion according to Merdeka. Construction of the project commenced in January 2025 and is expected to reach commissioning stage within 18 months.

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.

• Sulphur prices have been revised higher in the latest forecast after supply from the Middle East was lower than expected in February, and buyers with uncovered demand were forced to chase prices upwards. UAE sulphur exports normally fall at the start of the year due to scheduled maintenance, but sales in February this year were 200,000 tonnes short of what is typical. Prices may climb more than expected as buyers scramble to cover their shorts. If supply is slower to return than currently anticipated, momentum may push prices even higher in the short term.
