Midstream Oil and Gas


When the energy production environment presents complex challenges, filtration and separation systems from Parker present the solution. In today’s demanding energy market, keeping the pipelines full is not just an objective – it’s an absolute necessity. Parker offers innovative and site-specific filtration and separation solutions that help ensure integrity and purity along the entire production continuum.


The midstream phase involves the shipping and storage of crude or refined petroleum products. This important phase is the link between both the upstream and downstream phase. The midstream phase involves the moving of raw oil and natural gas extracted at the upstream phase and the transportation of the oil to the downstream phase of the process, where the oil is refined for use as a fuel product. Oil and gas is transported via all modes of transportation including pipelines. Pipelines may also be used to deliver the refined fuel products to downstream distributors.


Pipelines are one of the most efficient ways to transport and distribute oil and gas. However, large networks of pipes exist and must be maintained in order to make this a viable option. There are several obstacles involved in the piping of raw oil and gas as it typically needs to travel long distances. Moving raw oil and gas over long distances to the downstream processing plants requires extremely high pressure. In order to accomplish this, compressor/ pump stations are constructed at regular intervals along the pipeline network in order to maintain the pressure needed to keep the flow moving smoothly.


Additionally, oil and natural gas traveling through the length of a pipelines can collect harmful contaminants such as: compressor lube oil, water, and anti-corrosion chemicals used to reduce pipe corrosion. These harmful contaminants can result in compressor damage, chiller coil damage, increased pipeline maintenance, and restricted flow from pipe scale buildup.


Pipes carrying petrochemicals are often cleaned out by pushing a plug, or pig, through the pipes to remove built-up residue that restricts the smooth flow of fluid through the pipe. Pigging got its name from the sound that the plug makes as it travels down the pipe. To prevent fire or explosion nitrogen is the preferred compressed gas to push the pig. An oxygen free atmosphere cannot support fire and thus the hazard is eliminated.


Parker's Nitrogen Generators create pure nitrogen from your compressed air supply, usually 95% Nitrogen is sufficient for this use. After locating the generator at your site, compressed air is connected to the inlet of the generator and nitrogen is produced, at pressure and on demand.


MECHANICAL GAS SEALS APPLICATION: To reduce the volume of gases containing volatile organic compounds leaking to atmosphere, environmental agencies have instituted regulations limiting VOC emissions. Many large pumps or compressors contain mechanical gas seals that operate as non- contacting, dry running seals. These seals isolate compressed gases containing VOC’s from leaking to atmosphere. Mechanical gas seals are designed to perform with a wide variety of gases that can be harmful to workers and the environment. For example, the lubricating gas that is normally used to pressurize the seal is natural gas. A safer alternative to natural gas is dry, inert nitrogen gas which can be generated on site from standard compressed air at a very low cost, using the Parker Nitrogen generator.

    Compressor Booster Station

    As natural gas flows through a pipeline, it can lose pressure. Compressor booster stations located along the length of the pipelines keep the pressure at the proper level. Natural gas traveling the length of a pipeline can pick up contaminants such as compressor lube oil, water, and anti-corrosion chemicals. Without proper filtration the contaminants can cause serious damage.
