Casale acquires CO2 removal process

Casale has announced that it has acquired the license and know-how of the CO2 removal process developed and owned by Karpov Institute of Physical Chemistry (Russia).

Recently, Casale has been seeking to establish itself as a global provider of the complete production chain of nitrogen fertilizers, from the feedstocks to the end products.

The newly acquired technology has been widely and successfully applied in a number of ammonia plants designed by GIAP (Russia), such as the AM-70, AM-76 and AM-80 types. Several such plants in Russia and other countries are still in operation, and have proved capable of operating at capacities of 2000 metric tpd or more, after suitable revamping.

The Karpov CO2 removal process features a unique design of the internal parts of both the absorber and stripper columns. Access to Karpov’s technology enables Casale to revamp a GIAP ammonia plant up to 2100 metric tpd and more, substantially keeping the CO2 removal section, except for a few modifications to the internals of the columns.

This feature simplifies the entire revamp and helps to greatly reduce the overall cost, as proven in the revamp carried out by Casale of the GIAP-designed plant at Nevinnomysk Azot.

A similar revamp by Casale is reportedly due to follow suit at Novomoscosk Azot’s GIAP ammonia plant.
