# A major European refinery reduces crude preheat fouling, energy consumption and CO₂ emissions

## Download the case study

Processing a wider range of crude oils creates greater commercial opportunities - but it also increases the risk of fouling, higher energy consumption and unexpected operational challenges.

This case study shows how one of Europe's leading refineries used CrudePLUS\* to move from reactive fouling management to a predictive, data-driven approach.

## Download the CASE STUDY to discover:

- How the refinery addressed the growing challenge of crude preheat fouling after changing its crude slate.
- Why traditional laboratory testing and historical operating data failed to predict fouling risks associated with new crude blends.
- How predictive crude monitoring and the CrudePLUS solution enabled a proactive fouling management strategy.
- How the refinery achieved measurable improvements in operational performance, energy efficiency, and CO₂ emissions reduction.

 

 

## **Measurable results:**

- More than 50% reduction in crude preheat fouling
- Up to 2,000 tonnes of CO₂ emissions avoided during a single evaluation period.
- 754 tonnes of fuel gas saved
- Improved furnace efficiency and longer operating campaigns
- 456 crude samples analysed across 74 different crude oils.
