RECONSTRUCTION AND UPGRADING OF EXISTING BY-PRODUCT COKE PLANTS

Comprehensive reconstruction and upgrading of existing enterprises.
     
 

Apart from the list of new facilities which were built and put into operation, CONCORD GROUP has extensive experience and engineering potential enabling the Company to implement complex projects in modernization and rebuilding of existing by-product coke plants.

Reconstruction of coke over batteries of operational facilities requires a higher level of competence from the EPC contractor, requires attention to be drawn to the existing limitations of the facility and the peculiarities associated with integration into the existing infrastructure.

Using its experience, scientific research and information about the actual operation of facilities, CONCORD GROUP offers optimum solutions of reconstruction and technical re-equipment of by-product coke plants. The short list of works carried out by the Company includes:
