Ammonia Plants for sale

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 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.
