Abstract
A method and a device for separating off an electrolyte from a first synthesis gas and a second synthesis gas, each containing an electrolyte. The two synthesis gases are each subjected in a scrubbing column to a water scrubbing, in which a substantially electrolyte-free synthesis gas and also a scrubbing water loaded with an electrolyte that has been separated off are obtained. At least a part of the scrubbing water that was loaded with an electrolyte that has been separated off in the scrubbing of the first synthesis gas is used as scrubbing medium in the scrubbing of the second synthesis gas.
Claims9
A method for separating off an electrolyte from a first synthesis gas and a second synthesis gas, each containing an electrolyte, said method comprising:
- subjecting each of the two synthesis gases to a water scrubbing in a first water scrubber column and a second water scrubber column, respectively, wherein a substantially electrolyte-free synthesis gas and a scrubbing water loaded with electrolyte are separated and obtained,
- wherein at least a part of the scrubbing water that is loaded with an electrolyte separated off in the scrubbing of the first synthesis gas is used as scrubbing medium for the scrubbing of the second synthesis gas, and
- wherein said electrolyte in said first and second synthesis gases is ammonia and/or hydrogen chloride.
A method for separating off an electrolyte from a first synthesis gas and a second synthesis gas, each containing an electrolyte, said method comprising:
- subjecting each of the two synthesis gases to a water scrubbing in a first water scrubber column and a second water scrubber column, respectively, wherein a substantially electrolyte-free synthesis gas and a scrubbing water loaded with electrolyte are separated and obtained,
- wherein at least a part of the scrubbing water that is loaded with an electrolyte separated off in the scrubbing of the first synthesis gas is used as scrubbing medium for the scrubbing of the second synthesis gas, and
- wherein said first water scrubber column and said second water scrubber column are each positioned upstream of a methanol scrubber.
