Hydrogen Unit In Refinery
Refinery hydrogen production device
There are refineries today, and the method of hydrogen production is related to all things and cannot be ignored.
Selection of raw materials
Hydrogen production raw materials, there are many kinds. Common ones are naphtha, natural gas and the like. Natural gas is rich in methane, with a suitable carbon-hydrogen ratio, easy conversion to hydrogen production, and less impurities, simple pretreatment, and relatively low cost. Naphtha has a wide range of sources, but its composition is complex. It contains impurities such as sulfur and nitrogen, and needs to be carefully pretreated. After removing impurities, it can be used for hydrogen production. When selecting materials, when reviewing their cost, availability and quality, ensure that the raw materials are adapted to the device with the best efficiency.
Process
Steam reforming process is widely used. Under high temperature and catalyst conditions, the raw material reacts with water vapor to generate hydrogen and carbon monoxide. This process requires precise temperature control and pressure regulation to ensure efficient reaction. After the transformation reaction, carbon monoxide interacts with water vapor to increase the yield of hydrogen. There is also autothermal reforming, which integrates partial oxidation and steam reforming. It can provide self-heating and is suitable for specific working conditions. Membrane separation, pressure swing adsorption and other technologies are used to purify hydrogen, remove impurities, and improve purity to meet different hydrogen needs.
Plant operation and maintenance
The operation of the device depends on stability. Daily inspection requires checking whether the equipment has leakage, abnormal noise, and whether the meter reading is normal. The performance of the catalyst is related to the reaction effect, and it should be tested, maintained and replaced in a timely manner. And the refinery environment is complex, so fire prevention, explosion-proof and anti-virus safety measures are indispensable. Regular drills of emergency plans to prevent accidents.
The hydrogen production unit of the refinery is a key part of the production of the refinery. Only by taking good care of raw materials, processes and operation and maintenance can we produce hydrogen efficiently, help the refinery move forward steadily, and gain an advantage in the petrochemical field.
