Used Ammonia Converter from a 1000 STPD Ammonia Plant with Haldor Topsoe basket built in 1997. The ammonia converter had a complete Halder Topsoe retrofit in 1997 and only operated for about 5 years after this upgrade. Built by Struther Wells, 2600 PSI DESIGN @ 475 DEG. F., 84.125" INSIDE DIAMETER x 75'2.8125" OAL; 4.125" shell thickness; 3.125" head thickness; 19,135 gallon water capacity.

Used 1,000 TPD Ammonia Plant built in 1980. Has three process sections. (1) Syngas generation. In this section, natural gas goes through compression and desulphurization, and then enters medium pressure primary reformer and secondary catalytic reformer. Carbon monoxide catalytic conversion occurs in two temperature stages. (2) Syngas purification. Benfield system is used to remove carbon dioxide from raw syngas. CO2 is converted into methane. (3) Ammonia synthesis and refrigeration. A centrifugal compressor powered by steam turbine compresses purified syngas, which is then sent to ammonia synthesis reactor. Product ammonia is chilled by a refrigeration system and then delivered to storage tanks. This plant had several major upgrades after 1990, including: (a) synthesis column upgrade in 1996, (b) new technology for nitrogen recovery from purged gases in 1994, (c) new monitor system for the ammonia synthesis compressor and the refrigeration compressor in 1996, (d) replacement of tubes in the primary reformer in 2008, (e) new secondary reformer burner in 2014. (This plant is compatible with Urea Plant #434).

Used 635 TPD Ammonia Plant built in 1997, dismantled and stored for resale. The plant directly introduced hydrogen and nitrogen as feed-stocks into ammonia synthesis converter. There is no reforming section. This plant is ideal for a company which is short of natural gas supply but would like to set up ammonia production close to an air separation unit, a chlorine plant or other plants which generate hydrogen.

Used 100 TPD Ammonia Plant built in 1966. Skid-mounted, designed by N-Ren (Amopak process) immediately available for quick loading and shipment. All the equipment has been dismantled. The plant includes the process sections of (a) Natural gas desulfurization (b) Catalytic steam reforming (c) Carbon monoxide shift (d) Carbon dioxide removal (e) Methanation (f) Ammonia synthesis (g) Purification. The plant has (3) Worthington, multi-purpose and multi-stage electric motor driven reciprocating compressors (now only 2 such compressors available, A & B). Each compressor consists of (4) stages for syngas, (3) stages for process air and (1) stage for ammonia refrigeration. The plant also has (2) Worthington reciprocating electric motor driven compressors to recirculate the syngas back to the synthesis loop. The loop operates at 4,500 psig pressure. The primary reformer was rebuilt in 2011 and has not been used since then. There are 64 catalyst tubes in the reformer with tube material of HP modified, 25-35 with Niobium.

Used 1,140 TPD Ammonia Plant built in 1973. Gas enters the synthesis section at a ratio of approximately three parts hydrogen to one part nitrogen. This ratio is maintained with only small variances to enhance catalyst reaction during ammonia conversion. Compression raises the process gas stream to the higher pressure as coolers and chillers, utilized between compressor stages, maintain temperature. Following process gas to ammonia conversion over a high temperature catalyst bed, the process stream is cooled. Exchangers, coolers, and chillers are utilized to reduce the gas stream temperature with either water, ammonia or a cooler gas stream to drop out the liquid ammonia for storage. This plant is a part of an ammonia and urea production facility. Review Plant # 206 for the information of the 1,350 TPY urea plant.
