At the Drohobych Refinery, the thermal cracking unit has been shut down for scheduled repairs. All work is expected to be completed by June 27, followed by startup and bringing the unit to normal technological mode, the Western Information Corporation was told on June 16 by the press service of OJSC "NPK-Galychyna." \n \nAs explained by Mykola Bilyk, technical director of OJSC "NPK-Galychyna," "to burn off coke from the technological equipment, it becomes necessary every 60-70 days to shut down the unit and carry out scheduled repairs. In addition, constant monitoring is required of the condition of equipment operating under harsh technological conditions, at high pressures and temperatures." \n \nThe estimated cost of the repair will be 400 thousand hryvnias. The main scope of work is planned on the furnace and column equipment of the unit; in particular, replacement of 30-40 furnace tubes and return bends, pumping equipment, etc. is planned. \n \nThe thermal cracking unit processes medium and heavy vacuum gas oils in order to increase the yield of light petroleum products by 5-7%. Thermal cracking is carried out at a temperature of 450-550 degrees Celsius and a pressure of 2-7 MPa. \n
