Komsomolsk refinery updating water treatment for coke cutting
MOSCOW. Dec 21 (Interfax) - Rosneft's Komsomolsk Oil Refinery plans to modernize the water collection and treatment unit for hydraulic coke cutting in its delayed coking plant.
The design and survey work on the facility is supposed to be done by November 2013.
There are plans to conduct a pre-project study to make a decision in regard to cleaning water of suspended matter and coke particles after coke cutting, as well as covering the labyrinth system of the delayed coking plant. The following options will be considered: hydroclones, sanitary pumps, suspended crane, vacuum tank and other alternatives at the designer's discretion.
Under the terms of the tender for this project, the designer will be responsible for improper work on the design and working documentation, including deficiencies found subsequently in the course of construction and operation of the facility on the condition that construction and operation comply with this documentation.
Pre-commissioning work at the delayed coking unit began in November 2011, but had to be postponed several times due to complaints from city residents about foul odors. The unit produced its first product in June 2012. The commercial launch of the unit will boost depth of refining from 60% to 72%, and increase production of light oil products, as well as enable the refinery to produce a new product - petroleum coke. The unit has capacity to annually process 1 million tonnes of feedstock, which is heavy petroleum residue. ABB Lummus Global Inc (United States) provided the licensed technology and base design.
State oil major Rosneft plans to complete a set of measures to minimize environmental impact at the Komsomolsk Oil Refinery (KNPZ) by the summer of 2013. The measures to minimize the impact resulting from the installation of the delayed coking unit at the refinery will cost an estimated 300 million rubles.
