Renewable natural gas (RNG) facilities, wastewater treatment plants, and dairy operations face growing pressure to meet tighter purity and compliance standards. PSB Industries has developed its Oxygen and Moisture Removal systems to address this challenge, offering tailored solutions that combine precision engineering, turnkey installation, and lasting system reliability.
Engineered for High-Purity Gas Performance
PSB Industries’ advanced Deoxo-Dryer packages serve as the cornerstone of its gas purification technology, designed to remove oxygen from methane through a precious metal catalyst operating at high temperatures. Each system achieves less than 1.0 parts per million by volume (ppmv) oxygen at the outlet, easily outperforming most pipeline tariff requirements that demand under 5 ppmv. This high efficiency ensures RNG producers can maintain access to product pipelines and protect downstream infrastructure from corrosive damage.
Dual-Function System for Optimal Drying
Beyond oxygen control, each package integrates a dual-tower TSA and desiccant dryer that lowers water vapor content to under 4 lb per million standard cubic feet (MMSCF). The result is a consistently dry methane stream that supports product quality and peak system performance. To simplify installation and maintenance, every system includes essential components such as an H₂S guard bed, economizer, air and water coolers, moisture knockout, and automatic drain, creating a comprehensive, ready-to-operate solution.
Flexible Design for Every Application
PSB Industries customizes each system based on gas composition, flow rate, temperature, and pressure. The optional H₂S guard bed enhances durability by shielding catalysts and reducing maintenance costs over the long term. Turnkey packages are built to serve natural gas, landfill, wastewater, and coal bed methane operations, ensuring compatibility across diverse raw gas sources.
For the dairy industry, standardized Deoxo-Dryer models help reduce initial design costs while shortening lead times, an advantage for facilities seeking quick integration and dependable results.
Cost-Effective and Compact Solutions
By combining oxygen and moisture removal in a single platform, PSB’s systems minimize redundancies, trim both CAPEX and OPEX, and reduce total system footprint. Designs can be configured for use at different points within the RNG process, whether before, in between or after the gas upgrading system, providing operators with adaptable equipment that sustains compliance and operational excellence.
A Commitment to Purity and Reliability
PSB Industries continues to refine its gas purification technologies for today’s renewable and industrial markets. Each Oxygen and Moisture Removal system is engineered to guarantee performance, streamline operations, and secure long-term reliability in even the most demanding environments..
