Prisen membrane recovery and high-purity H2 extraction


 

Our company utilizes high-performance Prisma membranes imported from the United States, combined with a self-designed and optimized process flow, to recover hydrogen from purge gas in the ammonia synthesis process, vent gas from ammonia storage tanks, and tail gas from methanol production, and then reinject it back into the production system. This approach achieves the dual objectives of increased output and reduced consumption, with both hydrogen purity and recovery rate meeting 92% Furthermore, the by-products obtained—ammonia or methanol—can meet commercial quality standards.

 

Technical Features:
1 1. The core component, the membrane element, boasts a long service life, averaging over ten years.

2 The membrane core components exhibit excellent physical and chemical properties, with exceptional resistance to performance degradation, ensuring that the entire system maintains its performance over the long term.

High-performance metrics;
3 • Excellent separation efficiency, with high recovery rates and purity, coupled with energy savings and reduced consumption, enabling users to achieve maximum returns with minimal investment;
4 1. Adoption of a foreign patented design system ensures that the design solution closely matches actual operating conditions.

5 The entire system features low capital investment, low energy consumption, easy disassembly and assembly, no wear-prone components, simple control, strong modularity, and ease of expansion.

Applicable field: Synthetic ammonia ( Methanol ) Vent gas, ammonia tank vent gas, flash steam, decarbonization gas
