Petrochemical industry catalyst recovery and product dehydration project

1. Project Background:
The catalytic cracking (FCC) unit of a large petrochemical enterprise needs to efficiently recover valuable catalyst powder from slurry oil.. At the same time, in its downstream fine chemical sector, the final dehydration process of high value-added chemical products (such as PTA, PIA, etc.) has extreme requirements for the purity and humidity of the filter cake.

II. Challenges and Needs:

Catalyst recovery: The processing medium is a complex slurry containing high temperature and solvents, which requires extremely high equipment sealing and explosion resistance..

Product dehydration: It is required that the filter cake has extremely high purity, no cross contamination, and the moisture content should be controlled at an extremely low level (such as<5%).

Continuous automation: Must meet the requirements of petrochemical equipment“ Safe, stable, long-lasting, full, and excellent; Continuous operation requirements.

Safety Compliance: The entire system must comply with strict explosion-proof standards such as ATEX..

III. Nuclear Xu Solution:
For different sections, we provide customized solutions:

1.Catalyst recovery section: Adopting  XUClosed vacuum filter. Its fully enclosed structure perfectly solves the problems of volatile organic compound (VOC) emission and explosion prevention, and the special selection of filter cloth ensures efficient retention and recovery of the catalyst.

2.Product Dehydration Section: Selection  PBFHorizontal belt vacuum filter. Equipped with a multi-stage countercurrent washing device to ensure product purity; By using techniques such as hot air piercing through cakes or steam hood to enhance drying, the moisture content of the product is reduced to its limit.

Fourth, Application Effect and Customer Value:

1.Economic benefits: Catalyst recovery rate exceeds98%, significantly reducing procurement costs;; High value products have improved their market competitiveness due to meeting purity and humidity standards.

2.Safety and Environmental Protection: The entire production process is enclosed, with VOC emissions meeting standards, achieving green and safe production.
