OREANDA-NEWS. Acron continues Urea-1800 project to improve capacity at four production units commissioned in 1969-1970.

The capacity of Acron’s four urea units in Veliky Novgorod is now 1,800 tpd following an overhaul of four production units that were originally put on stream in 1969-1970. Investments in the project exceed RUB 500 million.

The upgrade included commissioning two 90-m3 high-pressure liquid ammonia centrifugal pumps, and assembling and commissioning two Аtlas Copco 18,000-Nm3/h centrifugal eight-stage carbon dioxide compressors. After replacing rotating equipment, the Company upgraded the synthesis and distillation shop by installing a set of internal equipment in the synthesis columns, replacing the gas bubbler heat exchangers in three synthesis units and assembling gas ammonia separators.
