Biogas Membrane Purification System for 97% CH4 Recovery

Biogas to Renewable Natural Gas: Advanced Membrane Separation System for Efficient Purification
Product Overview

Lide's Biogas Membrane Separation System transforms raw biogas into high-purity renewable natural gas (RNG) through a cutting-edge two-stage process: pretreatment and membrane separation. Raw biogas, typically composed of 55% CH₄, 45% CO₂, and trace impurities like H₂S and H₂O, undergoes rigorous purification to meet national natural gas standards (GB17820-2012, Class II). This system is engineered for sustainability, efficiency, and long-term reliability, making it ideal for biogas plants, wastewater treatment facilities, and agricultural operations seeking to monetize biogas resources.

Key Features & Advantages
1. Highly Efficient Purification Process

The system integrates a multi-stage pretreatment unit (including fine filtration, refrigerated dryers, and heat exchangers) to remove solid impurities down to 0.01µm, eliminate moisture, and adjust gas temperature to 30°C--optimal for membrane performance. The core membrane separation technology leverages selective permeation: "fast gases" (CO₂, H₂S) diffuse through the polymer membrane, while "slow gas" (CH₄) is retained as product gas. A multi-stage membrane module design with high separation coefficients ensures CH₄ concentration ≥97% and recovery rates ≥97%, maximizing resource utilization.

2. Compact, Low-Maintenance Design

With minimal moving parts, the system boasts a small footprint and low maintenance requirements, reducing operational downtime and costs. Its quick startup time allows rapid achievement of design specifications, ensuring continuous productivity. The membrane system's 10+ year lifespan guarantees long-term return on investment, supported by Lide's industry-leading after-sales service team.

3. Sustainable & Reliable Operation

Designed for 24/7 stability, the system operates at atmospheric inlet pressure, eliminating the need for high-pressure feed systems. All product gas指标 comply with GB17820-2012 Class II standards, making it suitable for injection into natural gas pipelines, vehicle fuel, or industrial heating.

Frequently Asked Questions (FAQ)
Q1: What is the typical startup time for the system?

A: The system reaches design specifications within a short startup period (varies by flow rate, typically 30-60 minutes), ensuring minimal delays in gas production.

Q2: How does the system handle H₂S and moisture?

A: The pretreatment stage includes H₂S scrubbing and refrigerated drying to remove moisture, protecting membranes from degradation and ensuring long-term efficiency.

Q3: Can the system be scaled for larger biogas plants?

A: Yes, the modular design supports flow rates up to 40,000 Nm³/d, with customizable configurations for higher capacities.

Q4: What after-sales support is provided?

A: Lide offers comprehensive support, including installation guidance, operator training, and 24/7 technical assistance to ensure optimal performance.
