300Nm3/H PSA Hydrogen Production From Methanol Miniature Scale
Zhangjiagang City Oils And Fats (Jiangsu Zhongding) 300Nm³/H Hydrogen Production From Methanol
Technology Application:
Methanol and deionized water are mixed evenly. After vaporization and overheating, under certain conditions of temperature, pressure and catalyst, mixed raw material for reforming reaction to produce reforming gas containing H2, CO and CO2. After pressure swing adsorption(PSA) separation and purification, high purity hydrogen product is prepared.
Methanol reforming
Main process description:
Recover the unreacted methanol and water in the circular buffer tank, and mix with the methanol feedstock which is from methanol buffer tank, (within a certain proportion of methanol and water) pressurized by metering pump into the heat exchanger, firstly heat exchange with the converter gas; After the first heat exchange, the stream enters into the steam superheater, secondly heat exchange with the heat conducting oil and complete vaporization and overheating. The temperature of the raw material steam reaches a certain high temperature and go into the reformer, complete the catalytic decomposition and conversion reaction at the same time, high-temperature reformed gas is cooling down with the in raw material liquid and circulating cooling water by heat exchanger and condenser. It’s the third heat exchange. The temperature is cooling to below 40 ℃ in the washing tower by the desalted water washing. The reformed gas mixture goes to a gas-liquid separator for water separation, and then goes into PSA purification section. The unreacted methanol is adsorbed by the desalted water, and back to recycling system by recycle liquid pump.
Key figures
Hydrogen pressure: 1.6~3.0Mpa
Hydrogen purity: 99~99.999%
Scale: 100~20000Nm3/h
Methanol consumption: 0.5~0.56Nm3/Nm3 H2
Turndown: 30 to 110%
Features and advantages:
The methanol has a high conversion rate (≥95%) and low consumption. The Two-high THiPSATM technology is applied.
The raw material of start-up methanol is closed-loop recycled, being energy saving and environmentally friendly.
Special adsorbent/catalyst has a long service life and low operating cost.
Special programmable control valve is of high automatic degree.
