Description

Technical Field

[0001] The utility model relates to the technical field of isobutane dehydration devices, in particular to a deep dehydration device for isobutane production. Background Art

[0002] High-purity isobutane is a key chemical product in the petrochemical industry. It is produced by cracking liquefied petroleum gas and purified through multiple physical separation steps. It is primarily used to produce isooctane through alkylation with isobutylene. It is used as a gasoline octane improver and can also be used as a refrigerant.

[0003] In the existing high-purity isobutane production process, dehydration of the isobutane gas is typically required to ensure the quality of the finished product. This conventional dehydration method involves installing multiple large-volume dehydration tanks in series, then sequentially introducing the isobutane feedstock gas into each tank for a multi-step dehydration operation. This dehydration method not only suffers from technical drawbacks such as the large equipment footprint, complex operational procedures, and high subsequent overhaul and maintenance costs due to the multiple dehydration devices, but also poses a significant challenge.

[0004] At the same time, the dehydrating agent has a certain service life. After a period of use, the dehydrating agent in the dehydrating tank needs to be replaced accordingly. However, the replacement of the dehydrating agent in the existing dehydrating tank is cumbersome and requires downtime for maintenance, which is time-consuming and labor-intensive and seriously affects production efficiency.

[0005] Therefore, in view of the above problems, a deep dehydration device for isobutane production is proposed. Utility Model Content
