Aniline is one of the basic organic chemicals used as an intermediate in the production of other chemicals (dyes, antioxidants, rubber and plastic additives and special chemicals). More recently, it has been especially in demand as raw material for the manufacture of polyurethane-MDI foam components (accounting for the consumption of roughly 75% of aniline).

ANILINE

TECHNOLOGYThe technology to produce aniline by means of catalytic hydrogenation of nitrobenzene has been jointly developed by BorsodChem MCHZ Ostrava, s.r.o. (formerly Moravské chemické závody) and the Institute of Chemical Technology Prague, now based on reputed licensor.

This process has distinctive technical and economic features, which allows to rank it among the best worlwide. The aniline production unit comprises three basic technological units: the hydrogenation train(s), the aniline rectification and the aniline water treatment.

HISTORYChemoproject Nitrogen a.s. is working on aniline in cooperation with Chemoprojekt, a.s.

Chemoprojekt, a.s. started its activity in aniline in 1979 when collaborating with the company Moravské chemické závody (MCHZ) for the supply of their first aniline plant. The cooperation with MCHZ continued for the revamping the same plant in 1998 to increase the capacity from 75’000 to 110’000 MTPY per year.

A 150’000 MTPY plant was licensed to the Japanese company TOSOH, which was erected and put in operation in 2005. On basis of the positive operating experience gained, TOSOH decided to duplicated the plant.

Other two hydrogenation units, each of 40’000 MTPY capacity of aniline, were implemented by Chemoprojekt, a.s. as turn-key project and put in operation in BorsodChem MCHZ Ostrava plant during the years 2005 and 2006.

In 2007 Chemoprojekt, a.s. designed a project for revamping of aniline distillation unit for BorsodChem MCHZ Ostrava.

Chemoprojekt, a.s. has concluded a Licence agreement for both engineering and turn-key projects. In cooperation with BorsodChem MCHZ, Chemoprojekt takes part in international competitions for the provision of turn-key aniline production units.

Construction of other potential hydrogenation units is expected in the Asian region and in the countries of the former Soviet Union.
