Rectification technological processes require the outside heat supply. One of the most safety and rational methods to provide with heat energy all the consumers in technological process is using of intermediate heat-transfer agent which, as a rule, is a special oil.

This equates to use one powerful boiler instead of a few small, that significantly increases the reliability and profitability of the systems, as well as safety, allows to bring out the source of bare flame from the borders of explosive zone, depresses opportunity of bare flame contact with gas or  liquid hydrocarbons contact.

There is a demand for effective ways to treat both associated petroleum gas, common at oil production sites as well as gas condensate produced alongside natural gas at gas condensate fields. This demand is boosted by several reasons: growth in oil and gas production, tightening of the ecological norms and emission standards, gradual decline in dry Cenoman gas deposits and a consequent shift to development of new gas condensate fields.


Let’s analyze potential gas-processing options for a small oil company. It is extracting up to 120 mln scm of associated petroleum gas per year. Currently the gas is flared.

A gas pipeline of intermediate pressure (3.5 Mpa) passes 10 km away from the oil treatment unit, where oil and gas are separated. Technical specs for adding the gas to the pipeline are as follows: -10°С dew point for water, -5°С dew point for hydrocarbons. Company’s oilfield can be reached by wheeled transport by road.
