Alkaline Water Electrolysis Hydrogen Generator

Short Description:

The Alkaline Water Electrolysis Hydrogen Generator consists of an electrolyser, a gas-liquid treatment unit, a hydrogen purification system, a variable pressure rectifier, a low voltage distribution cabinet, an automatic control cabinet and water and alkali distribution equipment.

The unit operates on the following principle: using a 30% potassium hydroxide solution as the electrolyte, direct current causes the cathode and anode in the alkaline electrolyzer to decompose water into hydrogen and oxygen. The resulting gases and electrolyte flow out of the electrolyzer. The electrolyte is first removed by gravity separation in the gas-liquid separator. The gases then undergo deoxidation and drying processes in the purification system to produce hydrogen with a purity of at least 99.999%.

Application

• High-purity hydrogen for semiconductors, polysilicon production and hydrogen refuelling stations.
• Large scale green hydrogen projects for the coal chemical industry and synthesis of green ammonia and alcohols.
• Energy storage: Converting excess renewable electricity (e.g. wind and solar) into hydrogen or ammonia, which can later be used to generate electricity or heat by direct combustion or for fuel cells. This integration increases the flexibility, stability and sustainability of the electricity grid.

Technical Advantages:

• Low power consumption, high purity: DC power consumption≤4.6 kWh/Nm³H₂, hydrogen purity≥99.999%, dew point -70℃, residual oxygen≤1 ppm.
• Sophisticated process and simple operation: Fully automated control, one-touch nitrogen purge, one-touch cold start. Operators can master the system after a short training.
• Advanced technology, safe and reliable: Design standards exceed industry standards, prioritising safety with multiple interlocks and HAZOP analysis.
• Flexible design: Available in skid-mounted or containerised configurations to suit different user requirements and environments. Choice of DCS or PLC control systems.

Other Advantages:

• Reliable equipment: Key components such as instruments and valves are sourced from leading international brands. Other equipment and materials are sourced from leading domestic manufacturers, ensuring quality and longevity.
• Comprehensive after-sales service: Regular technical follow-up to monitor equipment performance. Dedicated after-sales team provides prompt, high quality support.
