The customer approached Aggreko to enquire about our capabilities and how we could help them adapt to their pressing cooling concerns. We had helped supported with their Turnaround activities and contingency projects, so we were ideally placed to partner with them to find the right answer.
Every project is unique in its requirement, calling for a customised approach to project design to formulate the eventual engineered solution.
While the refinery’s engineering team had a good idea on the type of solution required to resolve their cooling limitations, the joint efforts of Aggreko’s cross regional teams and experts from local engineering, global engineering division and Aggreko Process Services (APS) offered valuable advice and alternative perspectives for varying operational components during the planning phase, including:
- Supplementary services for hose management for cost optimisation
- Resolution of site plot space constraints
- Risk mitigation of tainted water flowing into chillers due to corroded heat exchangers, by implementing detectors on buffer tanks to monitor potential leakage.
- Guidance on water flow rate optimisation to maintain constant gasoline rundown temperature during project tenure.
Our thorough approach led to an integrated turnkey Process Enhancement solution, comprising of air-cooled chillers which were deployed around a shell-and-tube heat exchanger provided by the customer, supplying 875 kW of cooling capacity to reduce the temperature of gasoline rundown from the reactor section to 22 ℃.
