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 CO2e. 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.

Henrik Rasmussen, Managing Director of Topsoe Americas, said: “Our collaboration with CountryMark goes back many years. With demand for renewable diesel continuing to grow, we’re excited to partner with CountryMark on their journey to produce cleaner fuels and contribute to America’s low-carbon energy future.”

Matt Smorch, CountryMark President and CEO, added: “We saw this as an opportunity to deliver increased value to CountryMark diesel fuel buyers, increase the demand for Indiana agricultural products, and add value to our refining assets.”

Coromandel starts trial operations at new acid plants

Coromandel International says that it has started trial production at its new sulphuric acid and phosphoric acid plants in Kakinada, Andhra Pradesh. The company says that this marks a crucial step towards transforming the unit into a fully integrated facility, significantly enhancing production capacity and diminishing reliance on imported raw materials for fertiliser manufacturing. The company is now focusing on a phased ramp-up. The new plants have of 2,000 t/d of sulphuric acid and 650 t/d of phosphoric acid, respectively. The integration of these acid plants is strategic, aligning with Coromandel's objective to strengthen backward integration in its fertiliser manufacturing value chain. By producing key intermediates in-house, the company aims to secure stable supplies, enhance cost efficiencies, and achieve greater self-sufficiency, thereby reducing dependence on imported raw materials. The project aims to replace over 50% of the Kakinada plant's imported acid requirements and mirror the integration levels seen at its Vizag and Ennore facilities.

Duqm Refinery looking at further expansion

Following an increase in its processing capacity, Duqm Refinery is now looking at further expansion projects at the $9 billion refinery project located, in the Special Economic Zone at Duqm (SEZAD) on Oman’s southeast coast. The refinery, which now has an expanded capacity of 255,000 bbl/d, is run by OQ8, a joint venture between Kuwait Petroleum International (KPI) and Oman’s OQ Group. Speaking to local media, CEO Abdulla Al Ajmi said that OQ8 has now begun front end engineering design on a reformer unit to upgrade naphtha into high-octane gasoline components such as reformate, a critical step in producing finished, specification-grade fuels. In addition to the proposed reformer unit, Duqm Refinery is also exploring opportunities to enhance value creation from its refining by-products, notably sulphur and coke.
