Engineering excellence in everything we do
APS is a dedicated, self-contained team, but one that’s closely integrated into all our work across the petrochemical and refining sector. Wherever we need process expertise, we have it.
How Aggreko's Process Services expert support works
The process optimization service from APS has executed thousands of successful projects, overcoming technical challenges and debottlenecking solutions with engineering expertise. Our work crosses four main stages:
- On-site assessment: We’ll attend your site to familiarize ourselves with the problem, your plant, and the most feasible solutions – whether you need energy solutions, temperature control support, or a solution that combines all our expertise.
- Process Design Package (PDP): Once the project scope is agreed, we’ll create the information needed to meet MOC requirements, conduct process and safety reviews, and facilitate operator training.
- Project management: APS provides project management throughout the entire process, helping to accelerate schedules and safeguard quality every step of the way.
- After-action report: We’ll provide a formal report that summarizes project benefits, best practices, lessons learned, and potential future improvements.
Applications across your petrochemical and refining plant
When you need a partner with expertise across every aspect of a functioning facility, you can trust APS for petrochemical support.
Crude tower
Enable winter-level production rates in high heat through effective overhead and rundown cooling, using heat exchangers.
Fluid catalytic cracker
Address common bottlenecks including wet gas compressor issues and low oxygen content in air blowers.
Alkylation unit
When temperatures increase, Aggreko chillers can help maintain distillation tower, rundown, and reactor operations.
