SynCOR Ammonia™ - New process for grassroots plants

By rewriting the book on ammonia plant capacities, SynCOR Ammonia™ enables greater economies of scale and paves the way for new benchmarks, new financials and new opportunities – all using proven technologies.

SynCOR Ammonia™ is a technology break-through in the ammonia industry. Where all ammonia plants today rely on conventional two-step reforming based on tubular steam methane reforming and an air-fired secondary reformer, SynCOR Ammonia™ utilizes the unique TOPSOE™ SynCOR™ solution, a process based on oxygen-fired autothermal reforming.

SynCOR Ammonia™ introduces a previously unseen scaling factor for single-train ammonia plants, thanks to a steam-to-carbon ratio of just 0.6 – reducing steam throughput by 80%. The result can be double-digit reductions in the cost per ton of producing ammonia – with greater savings achieved the further you scale up.

By introducing new economies of scale into ammonia production, SynCOR Ammonia™ gives plant owners breakthrough options for profitable expansion and provides new investors with an opportunity to enter the market with a sharp competitive edge.
