Compact Mature Process SMR Hydrogen Plant From 3000Nm3 To 4500Nm3

Jiangsu Improvement And Upgrading Of Hydrogen Production Unit By Natural Gas From 3000Nm3 To 4500Nm3

Technology Application:

Crude hydrogen (mainly CH4, Co, CO2, H2 and H2O) is produced from natural gas (low carbon chain hydrocarbons) by steam reforming process, and then purified by pressure swing adsorption technology to obtain hydrogen with purity meeting the requirements of users.
The natural gas is compressed to the appropriate pressure (according to the user's gas consumption and the optimal operating pressure) by the compressor, and then it is preheated for fine desulfurization. Then it enters the reformer with a certain proportion of steam for reaction. Then it passes through the waste heat boiler of the reformer gas, recovers the heat of the reformer gas, and enters the intermediate reformer for conversion reaction to obtain the crude hydrogen. After a series of heat exchange and cooling, the natural gas is cooled, Enter the pressure swing adsorption device, and finally purify.

Steam Methane Reforming - Hydrogen Production

TECHAIRS provides Steam Methane Reforming (SMR) technology for hydrogen production on both a small and large scale. SMR is a cost-effective and energy efficient way of producing hydrogen. High levels of purity can be reached by using Pressure Swing Adsorption purification technology.

In the SMR process a desulfurized feedstock (natural gas, refinery offgas, liquefied petroleum gas or naphtha) is compressed and pre-heated(gas pressure for raw material is lower than 1.6Mpa), mixed with water vapor after refining desulfurization, under the action of 800℃high temperature, a certain pressure and catalysts, alkane and water vapor contained in natural gas set off a chemical reaction to produce a reforming gas containing H2, CO, CO2, N2 and CH4. The reforming gas enters into the shift converter through the waste heat transfer, and CO is converted into H2 and CO2. CO2 is recycled through heat transfer, condensation, steam-water separation, automatic progr am control, and the gas passes adsorbent loaded with a plurality of specific adsorbents in turn, and the product of hydrogen is extracted after PSA adsorbing N2, CO, CH4 and CO2 through raising pressure. Impurities are released through depressurization and adsorbents are reactivated.
