Natural gas to LNG
Raw gas whose main component is CO can be converted to CO2 and H2 mainly through the conversion reactor, which can be used as one of the main raw gase…
The reformed gas hydrogen production system is designed to convert CO-rich raw gas into a hydrogen-rich stream through a catalytic shift reaction, followed by purification using pressure swing adsorption (PSA). In this process, carbon monoxide in the feed gas is first converted into carbon dioxide and hydrogen, resulting in a reformed gas mixture that serves as a key upstream feedstock for hydrogen production in coal chemical applications.
After purification, the system enables the production of high-purity hydrogen. When combined with CO₂ capture and recovery technologies, the desorbed gas can be further processed to recover carbon dioxide, which can be utilized for applications such as food-grade CO₂ production, improving overall resource utilization and economic efficiency.
This hydrogen production route is widely used in coal chemical processes due to its relatively simple configuration, stable operation, and favorable investment cost structure.
Process Flow Overview
The typical reformed gas hydrogen production system includes the following stages:
-
Raw gas preheating
-
Saturated hot water tower humidification
-
Gas-liquid separation
-
Catalytic shift reaction unit
-
Heat exchange system
-
PSA (Pressure Swing Adsorption) hydrogen purification
To further enhance carbon utilization efficiency, an optional MDEA-based decarbonization unit can be integrated before the PSA section to reduce CO₂ content in the feed gas.
