Topsoe technology selected for Indiana refinery

Topsoe has been selected as the renewable diesel technology partner for CountryMark’s Mount Vernon, Indiana refinery. Located in southwestern Indiana, the refinery processes 35,000 bbl/d of crude oil. With the addition of Topsoe’s HydroFlex technology, CountryMark aims to produce up to 250,000 barrels of renewable diesel annually. The new unit is expected to enable an emission avoidance of approximately 84,500 t/a of CO2 e. CountryMark, a farmer-owned cooperative, will use local soybean oil as the primary feedstock to produce renewable diesel, helping create a locally sourced renewable fuel economy in Indiana.

Marimaca to acquire acid plant

Marimaca Copper Corp. says that it has recently executed a binding asset purchase option agreement to acquire a used sulphuric acid plant in Chile from CEMIN Holding Minero. Sulphuric acid is one of the key input costs for the Marimaca Oxide Deposit, and the ability to produce a significant amount of its own supply will reduce exposure to a volatile acid market. The agreement has an exclusivity period of three months to allow further detailed technical and engineering reviews including capital and operating cost estimates for the installation and operation of the 150,000 t/a sulphuric acid plant, whose output would represent approximately 30-40% of total acid consumption at the Marimaca Oxide Deposit, depending on the phase of development. Marimaca says that, based on market research and quotations received, the estimated equipment cost of a new sulphuric acid plant of similar capacity is approximately $35-40 million, with a total installation cost of $50-60 million. The cost of breaking down and relocating the plant to the site at Mejillones and the start-up costs of the used plant are expected to be materially lower than cost of new equipment. Indicative operating costs show the potential for an approximately 30% reduction in acid cost relative to current long-term forecast and normal historical spot and contract acid prices delivered to Mejillones.

Upcycle launches potassium sulphate project

Upcycle Minerals Inc. has launched a brine to potassium sulphate fertilizer with carbon capture project in south-central Saskatchewan. The company says that it plans to use its mineral assets, including the Tuxford potash mineral permit and the Whiteshore and Lydden Lake Alkali Leases as feedstock for its patented process. Along with the production of potassium sulphate (SoP), the process also generates two co-products with established markets; ammonium sulphate fertilizer and precipitated calcium carbonate. Upcycle says that it intends to become an ecologically conscious, low-cost producer of SoP with low net CO2 emissions.

Copper output begins at Rio Tinto-backed project

Gunnison has started producing pure copper cathodes at its Johnson Camp Mine (JCM) in southeast Arizona, United States, from a solvent extraction-electrowinning (SX-EW) circuit and using leaching technology from Rio Tinto-owned Nuton. As well as giving Gunnison exclusive rights to deploy the proprietary process on run-of-mine ore, Nuton is a financial partner of the Phoenix-headquartered mine developer which has restarted copper production at past-producing JCM. The company’s next goal is to ramp-up to nameplate plant capacity of 25 million lbs/year (11,300 t/a) of finished copper.

Agreement for ancillary works on blue methanol plant

Transition Industries LLC has signed a heads of agreement with Italian contractor Bonatti SpA to deliver key infrastructure for the Pacifico Mexinol green methanol project in Sinaloa. Under the agreement, which includes a fixed lump-sum price, Bonatti will handle detailed engineering, procurement, construction, pre-commissioning, commissioning and startup for upgrades to the Terminal Transoceánica de Topolobampo port facilities. The work will cover methanol loading operations for export, underground transfer pipelines, vapor recovery systems, and dual fiber optic cables linking the main plant to the port. Bonatti may also build a closed-loop water pipeline to recycle municipal wastewater for plant operations, avoiding freshwater use and reducing environmental impact.
