That large equipment has the main role in the production process. In the columns the raw materials are divided into components. The result is the deasphalted oil. The facility’s capacities before reconstruction let to process over 850 thousand tons of goudron per year. During the same time almost 200 thousand tons of deasphalted oi was produced. After the reconstruction they will be able to get more volume of high quality products. In short, the productivity of the entire unit will increase.

Reconstruction and maintenance of deasphaltization unit this year is a very important step in its history and also a chance to set the aims and perspectives. Forthcoming two stages of reconstruction, modernization of fire-extinguisher system and of propane compression system.
