Refinery - Saturated Gas Revamp

Bantrel provided detailed engineering and procurement services to debottleneck the existing saturated gas unit and install a new MEROX unit at the Regina refinery. Bantrel's scope included design review, detailed engineering and procurement services including:

• Debottleneck of the existing saturated gas unit to increase throughput
• New desulphurization facility (a UOP licensed extractive MEROX process)                                   

Description of Work Scope:  

The scope of work for this project included complete process design review of the basic Engineering Design package performed by others. Bantrel provided detailed engineering and procurement services to debottleneck the existing saturated gas unit to increase throughput.

Bantrel also provided complete detailed engineering and procurement services for a new desulphurization facility to reduce the sulphur concentration in the saturated gas butane stream. UOP licensed extractive MEROX process is used for this project.

Bantrel used its 3D technology and new software called Plant Space in executing the revamp and new process units. The key challenges on this project were defining the shutdown and pre-shutdown work and executing the complex shutdown work in an orderly fashion.

Project consisted of 48 new / replaced / modified and abandoned mechanical equipment, and 400 instruments.  It was a challenge to coordinate with vendors to ensure the towers, column, pumps and exchangers were modified to keep the shutdown time to minimum. It was equally challenging to execute the fast track project. The splitter column was 138 feet tall and its unique design had many technical challenges including the vortex shedding issue and column dressing prior to its erection.

The project was also unique from the contractual point of view - lump sum engineering and procurement services, with process design guarantee. The project finished on budget and on schedule. The project was completed and commissioned in the spring of 2002.

We have also provided some construction site assistance to CCRL.
