Description
Technical field
The present invention relates to coal dust gasification methanol-fueled CLC fields, and in particular to a kind of powdered coal pressuring gasified Methanol Device CO 2 is returned
Receive automatic adjustment purified gas system.
Background technique
Purification process in powdered coal pressuring gasified methanol synthesizer generallys use low-temp methanol at present and washes technology, low temperature first
It is that a kind of typical physical absorption process is inhaled under low temperature, high pressure using the different solubility of various gases in methyl alcohol that alcohol, which is washed,
Most H2S and CO2 in unstripped gas is received, achievees the purpose that purification gas.And methanol synthesizing process requires low-temp methanol to wash
Need to retain certain CO2(3-4% while thoroughly absorbing H2S), once-through operation condition is harsher, and fine coal pressurization gas
Chemical industry skill 2.0MPa lower than coal-water slurry gasification operating pressure or so, operation requires low-methoxyl higher at 3.0MPa, special
It is not thoroughly to purify H2S after methanol loop liquid quality is declined to increase internal circulating load, therefore not can guarantee CO2 and contain
Amount, causes CO2 content in methanol-fueled CLC virgin gas relatively low, not only influences methanol-fueled CLC rate, while will also result in crude carbinol quality
Decline.From it is currently understood that the case where, low-methoxyl operation all suffers from this problem in most powdered coal pressuring gasified methyl alcohol product installations,
For guarantee technological operation it is up to standard, need periodically to replace methanol solution, and monthly several hundred tons methanol waste liquid take-away cause compared with
Huge economic loss, there is also biggish security risks.
Coal dust conveying needs a large amount of CO2, a part emptying in powdered coal pressuring gasified technique, and a part enters system, when
When system oepration at full load, low-methoxyl flash distillation CO2 product gas and gasification powdered coal conveying dosage it is in a basic balance, but work as system be reduced to
When 90% or less load, since usage amount is basically unchanged, quantum of output is reduced, it is therefore necessary to be supplemented part nitrogen and be met fine coal conveying
It uses, but the nitrogen filled into will cause the raising of methanol-fueled CLC inertia Gas content into rear system, the emptying of increase system is bound to cause
Effective blast takes loss, and system loading is lower, and nitrogen magnitude of recruitment is bigger, and emptying waste is more obvious.Low-methoxyl system H2S concentration
The CO2 gas concentration of top of tower flash distillation is high (concentration is higher than existing product gas), but pressure low (0.05MPa) can not be directly using only
It can emptying.It is the invalid discharge waste of CO2 gas on one side, is that CO2 dosage is uneven on one side, contradiction is than more prominent.
Summary of the invention
To overcome the above deficiencies, the invention provides a kind of high concentration low-pressure CO 2s for discharging low-methoxyl system
Gas recovery, it is ensured that while fine coal conveying Compressed CO_2 product gas dosage, automatically adjust in methanol-fueled CLC virgin gas
CO2 content, liberation low-temp methanol wash operation, reduce the powdered coal pressuring gasified methanol of the waste of effective gas and the loss of methanol replacement
