DELAYED COKER UNIT (DCU)

2022-11-23
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.

This large-scale project brought together some 700 contractors. UNIS contributed by handling the design work, localizing the entire project documentation to Belarusian standards and the client's internal rules, including telecommunication processing, evaluating the bids for HVAC and field instrumentation and completing all drawings related to the electrical part.

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.

HEAT RECOVERY STEAM GENERATOR, UPM NORDLAND PAPIER, GERMANY

2022-10-10
UNIS, in cooperation with its subsidiary UNIS Power, has successfully delivered a Heat Recovery Steam Generator (HRSG) to the German paper mill UPM Nordland Papier in Dörpen. Nordland Papier belongs to the Finnish UPM Group. The HRSG is part of a highly efficient new combined cycle, which is built to secure electrical power supply independently to public grid and to replace old boilers supplying technological steam for paper machines.

The steam generator works in horizontal design, with a support structure integrated into freestanding boiler modules filled with rows of tubes, called 'harps', forming the heating surface of the boiler. It is a single-pressure system with a pipe burner installed between the superheater bundles. The special burner arrangement allows the steam output parameters to be maintained in all operating cases required by paper machines. The paper mill has gained a more modern and much more efficient source of electricity, which will also significantly reduce the amount of CO2 emitted into the air.

During August 2022, the HRSG underwent a 30-day test run including verification tests of the guaranteed parameters. On 1st September according the Contract, the boiler was handed over to the customer for commercial operation.
