DELAYED COKER UNIT (DCU)

The trial operation of the Delayed Coker Unit (DCU) was completed at the Belarusian refinery "Naftan" on 21 October 2022. The unit was in the integrated testing phase since January 2022. During this time, work was carried out to eliminate the identified deviations in the operation of the process equipment and to adjust the operating parameters. During this time, the unit produced 617,000 tonnes of tar and asphalt and more than 360,000 tonnes of liquid petroleum products, including 219 tonnes of diesel.

The start-up of the coking complex at the Naftan refinery increased the depth of oil processing to 92% and the production of light oil products to 73%. A significant economic effect was thus achieved.

In addition to these activities on the main unit, UNIS, as the main designer and contractor, was involved in the construction of the liquefied gas cleaning unit of the Mercaptans Delayed Coking Unit (MEROX) and became the equipment supplier for the auxiliary plant (offsites) of the DCU. The coking complex would not have been without the MEROX unit and other related facilities. The MEROX unit was implemented under a UOP licence. All our work has been completed and successfully handed over in the autumn of 2021.
