Abstract
The invention relates to a process for recovering hydrogen (b) from crude gas (a) from a coke oven (110) in which the crude gas (a) produced in the coke oven (110) is initially compressed and in which impurities are subsequently removed from the crude gas (a) by pressure swing adsorption, wherein oxygen is depleted from the crude gas (a) using nonthermal plasma prior to the pressure swing adsorption, and to a plant for recovering hydrogen from crude gas.
Claims20
A process for recovering hydrogen from crude gas from a coke oven, said process comprising:
- initially compressing a crude gas produced in the coke oven,
- removing impurities from the crude gas by pressure swing adsorption, and
- depleting oxygen from the crude gas using nonthermal plasma prior to the pressure swing adsorption.
A plant for recovering hydrogen from crude gas comprising:
- a coke oven in which the crude gas is producible,
- a compression means to which the crude gas from the coke oven is suppliable and which is adapted for compressing the crude gas,
- a pressure swing adsorber to which the crude gas is suppliable after exiting the compression means and which is adapted for removing impurities from the crude gas and providing hydrogen, and
- a plasma generator arranged upstream of the pressure swing adsorber and adapted for producing nonthermal plasma in the crude gas.
A plant for recovering hydrogen from crude gas comprising:
- a coke oven in which the crude gas is producible,
- a compressor to which the crude gas from the coke oven is suppliable and which is adapted for compressing the crude gas,
- a pressure swing adsorber to which the crude gas is suppliable after exiting the compressor and which is adapted for removing impurities from the crude gas and providing hydrogen, and
- a plasma generator arranged upstream of the pressure swing adsorber and adapted for producing nonthermal plasma in the crude gas.
