Yan'an Petrochemical Sulphur Dioxide Adsorption Device Obtained Patent

Recently, the technical quality department of Yan'an Petrochemical Plant summarized and refined the utility model patent "An adsorption device for sulfur dioxide in dehydrogenation raw materials" according to the actual production and operation, which was authorized by the State Intellectual Property Office
.

The adsorption device can effectively remove sulfur dioxide in the dehydrogenation raw material, and realize the cyclic regeneration of the adsorbent while meeting the raw material requirements of the dehydrogenation process
.

It is understood that the mixed dehydrogenation unit of Yan'an Petrochemical Co.
, Ltd.
deep-processes propane, saturated liquefied gas, alkylated carbon tetra from the alkylation unit and the ether post-carbon tetra from the methyl tertiary butyl ether (MTBE) unit to generate the target product rich in Isobutylene and polymerization grade propylene further improve the added value of energy and comprehensive utilization rate
.

Compared with the existing adsorbent regeneration technology at home and abroad, the device not only realizes the effective removal of sulfur dioxide, but also can efficiently and reliably realize the regeneration of liquid-phase hydrocarbon sulfur dioxide adsorbent, which can save energy and reduce consumption while meeting production requirements.
