Title:
CARBON DIOXIDE RECOVERY SYSTEM FOR SUPERCRITICAL CARBON DIOXIDE DYEING EQUIPMENT
Document Type and Number:
WIPO Patent Application WO/2018/094762
Kind Code:
A1
Abstract:
A carbon dioxide recovery system for supercritical carbon dioxide dyeing equipment, comprising a raw gas separator, a compressor system, a hydrolysis and desulfurization tower, a desulfurization water cooler, an alcohol adsorber, a fine desulfurization tower, a second-stage waste cold recovery device, a precooler, a dryer, an adsorber, a first-stage waste cold recovery device, a liquefier, a liquefaction tower, a purification tower, and a subcooler that are connected in sequence. A compressor system is also connected between the fine desulfurization tower and the second-stage waste cold recovery device. The first-stage waste cold recovery device is connected to the second-stage waste cold recovery device. The liquefaction tower and the purification tower are separately connected to the first-stage waste cold recovery device. The carbon dioxide recovery system has a reasonably designed overall structure, and can effectively remove organic impurities in carbon dioxide by means of hydrolysis and desulfurization, adsorption, and drying, thereby ensuring the quality of recovered carbon dioxide.
