Launched in 2016, Acron PJSC’s Ammonia-4 plant is now working with a capacity of over 2500 mtpd after a revamp and successfully passed guarantee test runs. The project was delivered by the team of Acron engineers and Topsoe specialists working hundreds of miles apart. This has become the first heat exchange reformer (HTER) reactor put into operation in the FSU region.

The Ammonia-4 plant operated by Acron is one of the largest ammonia units in Europe. It is a major investment project of Acron’s site in Novgorod city, Russia, and it was the first ammonia plant built by Russian specialists without support from foreign workforce. The plant was commissioned in 2016, and total investment reached US$500 million.

In late 2017, it was decided to revamp the plant and reach 2500 mtpd. Topsoe specialists developed a project that involved another heat exchange reformer (HTER), changes to the CO2 removal section, and other modifications.

Despite the obstacles and travel restrictions seen in place during the year 2020 due to the COVID-19 pandemic, the team of Acron engineers and Topsoe specialists working hundreds of miles apart enabled the revamp of Ammonia-4, and after a successful overhaul in November 2020, the plant reached the capacity of over 2500 mtpd.

“Haldor Topsoe and Acron have been in a successful partnership for quite a while and the revamp project, that delivered in November 2020, marked another milestone in our cooperation. We believe our companies’ partnership will develop further for the benefit of both companies,” said Peter Vang Christensen, Managing Director of Haldor Topsoe’s Moscow office.

Aleksandr Popov, Chairman of the board of Acron, said: “Boosting the Ammonia-4 plant is an important project of Acron Group’s investment programme. Increasing its capacity will allow [us] to sufficiently increase production of nitrogenous and compound fertilizers on our Novgorod site.”
