CB&I unit Lummus Technology has won a contract from Kazakhstan Petrochemical Industries (KPI) for the license and basic engineering of a propane dehydrogenation unit and a polypropylene plant.

The two units, each with a design capacity of 500,000 metric tons per annum, are planned as part of KPI’s gas processing complex to be built in the western Atyrau region.

The company said that the propane dehydrogenation unit will make use of the CATOFIN technology for conversion of propane to propylene.

The polypropylene plant will use the Novolen advanced gas-phase polypropylene technology, which will enable KPI to produce a broad range of polypropylene products to meet the needs of both local and export markets.

Propylene is a building block used to produce a variety of products including polypropylene, a plastic used for household goods, according to the company.
