UOP/Albemarle Reactor Internals Provide Proven Performance

Reactor internals are a critical part of UOP’s hydroprocessing technology package. Maximum catalytic performance can only be achieved through good vapor/liquid mixing and distribution across the catalyst bed. Good distribution results in maximum catalyst utilization from start to end-of-run, maximizing product selectivity and catalyst run length.

In 2006, Albemarle and UOP created the Hydroprocessing Alliance, offering industry-leading hydrocracking and hydrotreating technology. Included in this alliance are proprietary reactor internals based on the complimentary strengths of both Albemarle’s and UOP’s designs. The Alliance Reactor Internals package includes the following:

  • Inlet Diffuser
  • Rough liquid distribution tray
  • D-Plex vapor/liquid distribution tray
  • Catalyst support grid
  • Quench zone
  • Outlet collector

The D-Plex™ vapor/liquid distribution tray is the latest improvement in this technology, and is a key technology enabler for superior hydrocracking and hydrotreating unit performance. With wide commercial acceptance, the D-Plex tray has shown superior performance as measured by even radial temperature profiles and excellent diesel and/or gasoline selectivity.

Benefits of our alliance Reactors Internals include:

  • Improved product selectivity
  • Increased catalyst activity and cycle length
  • Ease of installation and maintenance
  • Good distribution over a broad range of liquid and gas flow rates

UOP’s hydroprocessing reactor internals are custom designed and fabricated for each application to ensure maximum performance over the desired range of operating conditions. UOP equipment specialists oversee the design, fabrication, and installation providing a single-source responsibility for this critical hydroprocessing technology feature. Our close working relationship with a small set of worldwide fabricators insures maximum quality, short delivery times and low cost.

Over 450 Albemarle and UOP distribution trays have been installed and operated worldwide since 1991.
