Supporting Equipment: Piping and Pressure-Regulating Blowers Installed

Site photographs show two rounded, milky-white spherical gas holders standing firmly on a concrete platform, resembling a pair of white “pearls” within the factory grounds. Around the gas holders, stainless steel piping is neatly arranged, while pressure-regulating blowers, valves, and other supporting equipment have been installed. Workers in blue uniforms and red safety helmets carry out their tasks in an orderly manner, creating a scene of active construction.

Double Membrane Advantages: Reliable Sealing and Constant-Pressure Storage

Double membrane gas holders have become widely used as key biogas storage equipment in the paper, food processing, and livestock industries. Their multilayer membrane structure consists of an outer membrane, an inner membrane, and a bottom membrane. By regulating the air pressure between the outer and inner membranes, the system maintains biogas storage at a constant pressure.

These gas holders offer excellent gas tightness, resistance to wind, sunlight, and corrosion, low maintenance requirements, and a long service life. Compared with conventional wet-type gas holders, they are quicker to install and more economical, making them particularly suitable for small and medium-sized biogas projects.

Turning Wastewater into Energy: Biogas Recovery for Energy Savings

In the paper industry, anaerobic treatment of wastewater from pulp and paper production can generate substantial quantities of biogas. Releasing this gas directly into the atmosphere wastes a valuable energy resource and contributes to greenhouse gas emissions.

The newly installed gas holders will effectively collect and store biogas produced during anaerobic treatment. Following desulfurization and purification, the biogas will be used as supplementary fuel for boilers or for power generation, turning waste into a valuable resource and supporting the company’s efforts to reduce energy consumption and advance its green transition.necting wastewater treatment with energy recovery.

Advancing Green Production: Environmental and Economic Benefits

The installation of these two gas holders reflects the Xiaogan paper company’s commitment to green development and cleaner production. As its integrated biogas utilization system continues to improve, the company will achieve a better balance between cost savings, operational efficiency, and emissions reduction, contributing to the sustainable development of the paper industry.
