US engineering contractor CB&I has signed an agreement for a long-term alliance on syngas with Danish catalysis and process technology company Haldor Topsoe. Under the deal, CB&I will promote Haldor Topsoe’s syngas-based technologies, which the US-firm said complements its existing portfolio. The alliance adds eight Haldor Topsoe process technologies to CB&I’s current offering of more than 90 technologies and 3,500 patents, while also allowing the US firm to capitalize on the Lyngby-headquartered company’s expertise in engineering, procurement and construction (EPC).

CB&I will also work with Haldor Topsoe on providing EPC services to plants in North America. Patrick Mullen, CB&I’s chief operating officer, said the alliance gives it additional competitive offerings to the industry, adding that the two companies have a long history of technology collaboration. Both companies are working together on a refinery upgrade for Pertamina in Indonesia. The project at Pertamina’s Unit V refinery in Balikpapan, East Kalimantan, will use CB&I’s CDAlky advanced sulfuric acid alkylation process and Haldor Topsoe’s wet gas sulfuric acid technology.

CDAlky is an environmentally friendly alternative route to obtain high-octane premium gasoline that eliminates the need for human contact with sulfuric acid.
