Contract expected on oil project

Contract expected on oil project

Spetco’s contract with the Kuwait Oil Company (KOC) to install depletion compression systems and sulphur recovery units (SRUs) is said to be awaiting final approval. The $460 million project will upgrade two key facilities in North Kuwait, and Spetco says that it expects project execution will start quickly after final approval. The project involves installing new units at the Early Production Facility 50 (EPF-50) and Jurassic Production Facility 3 (JPF-3) using uses a build-own-operate-transfer (BOOT) contract model. The contract was originally tendered in 2023, but scope changes meant that the deadline has been extended several times.

The aim of the work is to sustain production from the facilities by installing compression systems and SRUs. The first part focuses on installing a new medium-pressure (MP) compression system and SRU at EPF-50. The second part focused on installing a new MP compression system and SRU at JPF-3. The EPF-50 and JPF-3 facilities receive sour wet hydrocarbons reservoir fluids through flowline gathering networks and trunk lines. Crude, gas and water are separated in a separation section currently receiving well fluid at 1,100 psig, and the crude is stabilised to export after desalting. The separation section consists of HP, MP and low-pressure (LP) separators in series. MP and LP gases are compressed to HP and combined with gas from HP separators. The gas is then treated in gas sweetening and dehydration units before being exported via pipeline. As the well fluid pressure depletes to MP, the combined feed from the inlet production headers and test header will be routed through a crude pre-heater to the new MP separator, which operates at about 425-450 psig. The new compressors will compress the gas from MP to HP.

The EPF-50 facility can currently process 200 million scf/d of gas, 50,000 bbl/d of oil and 130 t/d of sulphur. Originally, the upgrade project was expected to increase the volume of sulphur it can process to 270-310 t/d, but after the proposed changes to the scope, the capacity is now expected to be larger. The JPF-3 facility can currently process 150 million scf/d of gas, 50,000 bbl/d of oil and 200 t/d of sulphur. Originally, the planned upgrade was expected to increase the volume of gas that the facility can process to 240 million scf/d and the volume of sulphur to 440 t/d, but due to the scope changes, the capacity of JPF-3 will now be increased by more than the volumes outlined.

Merdeka Battery to build new HPAL plant

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.

Liquid Wind to progress abandoned renewable methanol project

Liquid Wind has announced the development of a new 100,000 t/a green methanol project in Örnsköldsvik, Sweden, in collaboration with local energy company Övik Energi. Övik Energi’s combined heat and power plant in Örnsköldsvik was due to be the site of Ørsted’s FlagshipONE project, which was slated to produce 55,000 t/a of green methanol from 2025. A final investment decision (FID) was made in late 2022 when Ørsted bought out Liquid Wind’s 55% stake in the project, but the Danish offshore wind company chose to discontinue FlagshipONE in August 2024.

Samsung to build UAE’s first methanol plant

UAE-based chemicals and transition fuels hub TA’ZIZ has awarded an engineering, procurement, and construction (EPC) contract worth $1.7 billion to engineering company Samsung E&A to build the UAE’s first methanol plant. The facility will be located at the Al Ruwais Industrial City in the western part of the emirate of Abu Dhabi. It is projected to produce 1.8 million t/a green methanol, powered by clean energy from the grid, with the plant scheduled for completion in 2028.

ExxonMobil and Trammo sign low carbon ammonia offtake agreement

Trammo, Inc. and ExxonMobil signed a heads of agreement to advance discussions for Trammo’s long-term offtake of 300-500,000 t/a of low-carbon ammonia from ExxonMobil’s Baytown, Texas facility. The facility is expected to produce virtually carbon-free ‘blue’ hydrogen with approximately 98% of CO2 removed, and will use this low-carbon hydrogen to make low-carbon ammonia. Trammo, a leading international physical commodity trader, will leverage its market and logistical expertise to deliver and sell in Europe and worldwide this unique low-carbon ammonia for use as fertilizer feedstock and for other key industrial applications.

Casale to license renewable ammonia plant

Casale is partnering with Indian renewable energy company Avaada Group to develop a 1,500 t/d green ammonia plant in Gopalpur, Odisha. This represents India’s largest grassroots green ammonia facility to date, and will be powered entirely by renewable energy. Casale will provide the ammonia process license, basic engineering package, proprietary equipment, and detailed engineering review, ensuring the facility operates at the highest levels of efficiency and sustainability. The plant will use Casale’s FlexAMMONIA technology, part of the FLEXIGREEN® portfolio.
