Product Description

As an important modern energy source, natural gas is widely used in various fields. For different gas sources, the application methods adopted are also different.

Casing gas recovery compressor
Casing gas means that when oil wells are producing oil, there will be natural gas in the casing. If the pressure is high, it will affect the oil production. In the past, it was vented directly. First, it polluted the environment, and second, it was a waste of energy. Therefore, Nowadays, the use of compressor pressure recovery is not only beneficial to oil production and environmental protection, but also a good measure to maximize economic benefits. The main components of the gas are methane, ethane, carbon 3, carbon 4 and other gases. Hydrogen sulfide and water are also mixed in it, and the ingredients are relatively complex. Before entering the compressor, it generally needs to be purified to remove acetone and liquid free water. Then it can be increased to different pressure levels according to the different needs of users.
1. For direct recovery through the oil pipeline, the pressure needs to be increased to about 15~20 kg, depending on the pressure of the oil pipeline.
2. Press to about 45 kg and transport by medium-pressure tanker.
3. Press to 250 kg and transport by high-pressure tanker.

The latter 2 methods are suitable for use in gathering and transportation stations. Most single wells have small gas volumes and are relatively scattered, which is not conducive to rapid loading and transportation of tank trucks.
Casing gas recovery compressors are also suitable for oilfield associated gas, wellhead gas and other similar working conditions.

Pipeline natural gas boosting
During the use of pipeline natural gas, due to factors such as the distance of the pipeline, pipe diameter, elbows and other factors, a certain amount of pipe damage is caused, which can easily lead to insufficient pressure when using gas. At this time, it is necessary to use boosting equipment to increase the pressure of natural gas to meet the usage requirements.
