Hanzhikang: Efficient Filtration For Natural Gas Plants

Dec 15, 2025 Leave a message

As a key clean energy source for global energy transition, natural gas faces complex impurity challenges throughout the entire chain of extraction, gathering, transportation, and processing.

 

During gas field extraction, natural gas is accompanied by solid particles such as formation sand and cuttings; in the compression and transportation process, compressor lubricating oil is prone to forming oil mist aerosols; and the saturated moisture in natural gas combines with acidic components like hydrogen sulfide and carbon dioxide to form corrosive droplets. Without effective treatment, these impurities not only reduce the calorific value and quality of natural gas but also trigger serious safety hazards: solid particles cause wear and leakage of precision components such as compressor cylinders and valves; oil mist contaminates catalysts in subsequent processing units; corrosive droplets accelerate corrosion and perforation of pipelines and equipment, and may even lead to explosion accidents.

According to industry data, equipment failures caused by impurities account for 35% of total failures in natural gas processing plants, increasing operation and maintenance (O&M) costs by approximately 20%-40%. Therefore, efficient and stable filtration and separation technology has become a core requirement for natural gas plants to ensure production safety, improve product quality, and control operational costs.​
