Preheat Exchanger Trains

Typically, because of the lower temperatures, fouling is not as severe in Crude Stabilisation exchanger trains, as in Oil Refinery preheat trains. However, exchangers will inevitably foul to a degree, in most cases, on both tube-side and shell-side. Consequently, the impact on the process can be severe, as heat transfer performance drops, increasing the load on the Heater/Furnace. Throughput may be further reduced by an decrease pressure drop through the exchangers.

Traditionally, you extract and remove exchanger bundles to the wash bay for High-Pressure Water Jetting, to remove the fouling. This can take several days, requiring significant mechanical preparation for removal and re-insertion of the bundle. If the bundle is critical to the Heater Inlet Temperature, a reduction in throughput may be unavoidable while the exchanger is out of service.

CORE provides bespoke formulations that allow decontamination of entire Preheat Trains in-situ at Turnarounds, removing costly bundle extraction and jetting. It can wash the entire train in a single, large-close loop, using CORE formulations to remove asphaltenic or waxy deposits. Restoration of critical heat transfer can be in as little as 36 hours.
