Challenges
Engineering to produce biomethane (720 Nm3/h) from biogas sourced from a wastewater treatment plant (1200 Nm3/h), aiming for profitability and urban benefits.
Solutions and Results:
- Implement a specialized Pressure Swing Adsorption (PSA) system for CO2 removal and adapt it to handle H2S reduction.
- Detailed Front-End Engineering (FEL3) for electrical, control, piping, mechanical, and process aspects of the biomethane system.
- Size, select, and provide a skid-mounted desulfurization and dehydration system capable of removing up to 70 l/h of water and up to 200PPM of H2S from the biogas.
- Design gas, cooling water, and compressed air pipelines, along with drainage solutions.
- Ensure proper selection and sizing of safety venting systems and supports.
- Prepare specifications, work quantities, and Process & Instrumentation Diagrams (P&IDs).
- Provide comprehensive electrical and control documentation, including connection diagrams, single-line diagrams, control loops, cable tray layouts, equipotential bonding, grounding grids, load studies, and area classifications.
- By implementing these solutions, our aim is to address challenges and create opportunities, resulting in economic viability and city-wide advantages through advanced biogas utilization.
