Process & Mechanical Assistance for Asset Improvement
Process & Mechanical Assistance for Asset Improvement Cat Feed Hydrotreater Reactor Replacement Study and Design
SITUATION
Customer
- APAC Refiner
- Needed redesign for a new reactors
- Reactors required replacement due to high temperature hydrogen attack (HTHA)
Objectives
- Provide study of two locations for new reactors and provide process estimates of unit performance with new reactors
- Later provide design for new reactors
APPROACH
- Client provided the Licensor’s Mechanical Design Specification for replacement of three reactors.
- Multi-disciplined team studied replacing with only two reactors at two potential locations in the refinery.
- Worked closely with the Client and their catalyst supplier to update a new process basis for the project.
- A Design Basis Specification was issued to the Client, and later new abbreviated process design information and a new Mechanical Specification was produced.
RESULTS
Outcome
- Location study identified replacement at location of existing reactors
Value
- Timely delivery of reactor replacement design in absence of resources from the Licensor
