Natural Gas Industry


Introduction

In the natural gas industry, fluid filtration products are the core technology to ensure production safety, improve process efficiency and meet environmental standards, and run through the whole process of gas field development, processing, storage and transportation and terminal application.

Upstream production and treatment: In the development of unconventional gas reservoirs such as shale gas and tight gas, natural gas produced from high-pressure gas Wells often contains sand, cuttings and condensate. Multi-stage cyclones and efficient sand filters are used to trap solid impurities and prevent wear on downhole tools and surface pipelines. For sulfur-containing natural gas (such as H₂S and CO₂), the special filter material (such as iron oxide or molecular sieve) in the gas desulfurization tower can adsorb acidic gases to avoid equipment corrosion and environmental pollution.

Midstream purification and liquefaction: Once the natural gas enters the treatment plant, it is removed by deep dehydration filters (such as molecular sieve adsorbents) to prevent ice crystals from clogging pipelines during the cryogenic liquefaction (LNG) process. At the same time, mercury adsorption filters are used to remove trace mercury elements in natural gas and protect key equipment such as aluminum heat exchangers. Pre-liquefaction also requires the interception of residual particles through a particle filtration system (accuracy below 1 micron) to ensure LNG purity meets trade standards.

Downstream storage and terminal: In LNG carriers or tankers, low-temperature filters need to withstand extreme temperatures of -162 ° C to prevent impurities such as ice and wax from affecting the safety of storage tanks. Dust filtration and trace oil interception technologies ensure the combustion efficiency and safety of end-users (such as gas turbines and household gas) before natural gas is transferred and distributed to urban networks. In addition, the high-pressure filtration system of the compressed natural gas (CNG) filling station can effectively remove lubricating oil residues and particles in the gas to avoid engine damage.

Environmental protection and intelligent innovation: With the acceleration of low-carbon transition, the treatment of produced water in natural gas fields relies on ultrafiltration membrane and activated carbon adsorption technology to achieve oil-water separation and pollutant discharge standards. In terms of intelligence, the application of online monitoring sensors and self-cleaning filters can track the status of the filter element in real time and optimize the maintenance cycle, reducing operating costs.

At present, the natural gas industry is responding to the challenges of complex gas sources (such as high sulfur, high CO₂ gas fields) and extreme working conditions through high-precision filtration technology, while promoting the research and development of filtration materials in emerging scenarios such as hydrogen energy and natural gas mixed transportation, providing key support for the green and efficient development of the industry.
