Engineers with PJSC “Naftogazvydobuvannya” (DTEK Oil&Gas) received patent No. 111960 for a utility model of the vapor–liquid separator. By improving the design of one of the most important devices used for the normalization of natural gas, the company’s engineers enhanced its performance by 7%.

The design was developed by Oleksii Raptanov, Bogdan Kukura, Sergii Gapon, Rusnal Synelnyk, Maksym Myshko, Mykhailo Melnychuk, and also subcontractors’ personnel. They suggested making changes in the design of the internal configuration of the separator by fitting two special separation stages inside the container. The first one is made of inertial separating elements and a set of bumper plates. The second stage comprises of section partitions with a louver pack. This way, a gas flow easily envelopes the resulting “pockets”. At the same time, drops of liquid moving together with a gas flow collide with the “pockets” by inertia, settle on the bumper plates and flow down towards the bottom section of the frame, without damaging the structure of the liquid film and secondary drop entrainment.

This separator configuration design has already been installed and tested at the Semyrenky gas treatment plant operated by Naftogazvydobuvannya. As a result, the performance of the separator improved by 7%: gas condensate extraction increase by two tons per day, and the dew point temperature (by moisture and hydrocarbons) of gas supplied to a gas transportation pipeline reduced by 4 °C.

“Similar separation equipment is used by quite a few Ukrainian operators. This is why we think that our idea will be useful for other gas extracting companies as well as companies engaged in the transportation of gas. We are constantly striving to improve the efficiency of production processes, and employ both science and proprietary innovations in this pursuit,” said Oleksii Raptanov, director for hydrocarbon extraction and processing at DTEK Oil&Gas.
