Ultra-Low Pressure Continuous Reforming Technology

The unit constructed using this technology demonstrates excellent technical indicators, including C5+ liquid product yield, hydrogen yield, and energy consumption, reaching internationally advanced levels. It is characterized by simple operation, high safety and reliability, high product yield, low energy consumption, and low capital investment. Compared with units of the same scale, engineering costs are reduced by approximately 4% to 5%, offering significant economic benefits.

Key Features & Benefits

The reactors are arranged in overlapping pairs, and the internal components adopt a centripetal flow design, which reduces manufacturing and installation complexity, lowers equipment investment, and facilitates operation and maintenance.

Catalyst transport employs a "novel valveless conveying system," which reduces catalyst attrition and ensures strictly continuous catalyst flow within the regenerator.

The lock hopper control system incorporates neural network-based advanced intelligent control technology, allowing for more stable control performance. A surge tank and corresponding control measures are configured in the lock hopper medium flow path to further enhance system stability.

Excess flue gas from the regeneration section is vented at the outlet of the chlorination zone, making the process adaptable to low-carbon coke burning and increasing operational flexibility. The regeneration gas adopts a “dry and cold” circulation mode, effectively preserving the catalyst's specific surface area and long-term activity. Dechlorination of the regeneration gas is achieved through a combination of caustic scrubbing and adsorption processes, minimizing chlorine-induced corrosion in the system.

Countercurrent Continuous Reforming Technology

This technology introduces a novel concept of matching reaction severity with catalyst activity state. Compared with units of the same scale, units employing this technology achieve higher aromatics yield and pure hydrogen yield, while reducing catalyst attrition by more than 60%. The technology has reached an internationally advanced level.

Key Features & Benefits

Four reactors are arranged in parallel, facilitating reactor fabrication, installation, operation, and maintenance.

The top-in, top-out flow configuration ensures more uniform flow distribution within the reactors.The elimination of lock hoppers simplifies the catalyst circulation and transport system, significantly reducing catalyst wear.

Regeneration gas operates in a dry and cold circulation mode, which slows the decline in catalyst specific surface area and extends catalyst life.
