Custom-engineered systems help RNG operators bring biogas up to pipeline specification
PSB Industries, a specialist in the design and fabrication of systems for dehydrating and purifying gases and liquids, offers skid-mounted PSB Methane Deoxo systems and dryer skids for removing oxygen and moisture from renewable natural gas (RNG).
Biogas from landfill, digester and wastewater sources can contain oxygen and moisture that make it unsuitable for a product pipeline. PSB's skid-mounted and integrated deoxo and dryer systems are designed to remove these contaminants from biogas, helping operators meet pipeline specifications.
Each system is engineered around the customer's gas composition, flow rate, temperature and pressure. An optional H₂S guard bed can be included to protect the catalytic reactor from hydrogen sulphide exposure. For price-sensitive dairy digester applications, PSB Industries also offers standard models designed for straightforward integration with upstream and downstream equipment.
PSB Methane Deoxo systems are designed for typical inlet oxygen concentrations ranging from 0.1% to 2.5% by volume and can reduce oxygen to less than 0.1%, or, where required, to less than 5 ppmv O₂. Following oxygen removal, PSB's dual-tower desiccant dryers remove moisture to less than 7 lb/MMSCF and, more typically, to less than 4 lb/MMSCF. According to PSB Industries, these performance capabilities help operators meet stringent gas-quality targets while supporting reliable, continuous operation. Standalone oxygen or moisture removal systems are also available, depending on the application.
PSB Industries says its systems draw on decades of engineering experience to deliver skid-mounted gas dehydration and purification equipment tailored to customers' process requirements.
