Methanol-to-hydrogen desorption gas
Thread Content
I would like to ask: How is the desorption gas produced in the methanol-to-hydrogen process typically handled? Can it be used as fuel gas in a heat transfer oil furnace that normally uses natural gas, or should the desorption gas be vented directly or burned in a flare?
Our scale is not very large; it’s a hydrogen production unit with a capacity of 700. Can the CO and methane emitted during gas release meet the environmental regulations?
If it is vented directly, can the levels of CO and methane meet environmental regulations?
It depends on the scale of your installation~~ If it’s below 1000, and there is a heat transfer oil system available, then heat can be generated by burning heat transfer oil in a furnace； There is no heat-conduction system available; flaring is an option, but direct emission is likely not feasible given that the exhaust gas contains 35% hydrogen and comes from a facility with a capacity of over 1000. Considerating the production of by-products in the form of food products or chemical-grade carbon dioxide could help reduce the overall production costs~~
Analysis of pressure instability and furnace temperature fluctuations during combustion in the furnace
A buffer tank is needed. What level have you determined for the hydrogen content in the gas?
With a hydrogen content of around 30%, it has a low calorific value and a high CO2 content; will this affect the thermal efficiency in a heat transfer oil system?
It will increase the load on the furnace without much increase in heat; your hydrogen content is too high – aren’t you making any adjustments?
