Ammonia synthesis

Optimal and stable performance for decades

More than 80 years of experience with ammonia synthesis enables us to provide the best solutions for the ammonia industry. Our well-known radial flow converters ( S-200, S-300 or S-50 ) and our KM catalyst family will ensure an optimal and stable performance of the ammonia synthesis section for decades.

Catalysts for ammonia synthesis

KM1 catalyst

KM1 is an iron-based ammonia synthesis catalyst. It is used in the majority of the world’s ammonia converters to convert synthesis gas containing hydrogen and nitrogen into ammonia.

KM 111 catalyst

KM 111 is a magnetite-based ammonia synthesis catalyst optimized for performance in the lower bed of the converter, where the concentration of ammonia is higher.

KM1R catalyst

KM1R is a pre-reduced iron-based ammonia synthesis catalyst containing a number of carefully selected promoters. Using KM1R significantly reduces the time required for catalyst activation.

KMR 111 catalyst

KMR 111 is a pre-reduced ammonia synthesis catalyst for optimized performance in lower bed of the converter. It delivers a fast activation time and only generates minor amounts of water.

RC-87 HEAT-X™ catalyst

The RC-87 HEAT-X™ is a nickel-based non-alkali pre-reduced catalyst for heat exchange steam reforming. It features unmatched mechanical stability across the temperature range.

Ammonia converter basket S-200

The S-200 ammonia synthesis converter is a two-bed radial flow converter with indirect cooling between the catalyst beds.

Ammonia converter basket S-300

Compared to the S-200 converter, the S-300 has three catalyst beds. This results in higher conversion into ammonia and thereby increased production efficiency.

Ammonia converter basket S-50

This is a single-bed radial flow converter, which is added downstream of the main converter in series to increase ammonia conversion. It is designed in a hot shell and a cold shell version.

Waste heat boiler (ammonia loop)

This loop boiler is based on a patented bayonet tube design which ensures that all low alloy metal parts are kept out of temperature zones where nitriding is a concern.

Ammonia electrical heater

Compared to conventional gas-fired heaters, this electrical heater offers compact, safe, remotely controlled and quick start-up of the ammonia plant.

ModuLite™

With ModuLite™, the dream of fast-deploying, small- or medium-scale production becomes a highly feasible reality by pairing our technology with modular design.

SynCOR Ammonia™

Ideal for grassroot plants. It introduces a previously unseen scaling factor of single-train ammonia plants, thanks to a steam-to-carbon ratio of just 0.6, reducing steam throughput by 80%.

Two-step reformer based ammonia process

Our Low Energy Ammonia Process uses steam and air reforming and is applicable for both small and large-scale capacities up to 3500 MTPD of ammonia.
