The first and simple step on your renewable diesel journey
Co-processing provides an easy way for refineries to start their renewable journey. By replacing even low amounts of fossil feedstock with renewable feedstock, your refinery can produce renewable fuel – and take the first step towards becoming a biorefinery.
How does it work?
Renewable feedstock can be introduced directly into your diesel hydrotreater with your fossil feed. The end-product will be a combination of renewable and fossil diesel. The renewable propane and methane will be released through the off-gases.
In most cases, up to 10% renewable feedstock can be added with limited or no equipment modifications. We do, however recommended installing a selective renewable grading and hydrodeoxygenation (HDO) catalyst for maximum yield and contaminant pick-up capacity.
For co-processing with more than 10% renewable feedstock, a revamp may be required, but this solution is still faster and with lower CAPEX than a grassroot unit.
Benefits of choosing renewable co-processing in your diesel hydrotreater for production of renewable fuel
Limited or no revamp of plant required
Renewable grading and HDO catalyst can be included fast, e.g., by next turn-around or even sooner by skimming
It’s a low CAPEX solution
Easy implementation – no need to wait for 100% renewable grassroot unit
You can choose your own co-processing starting point 
Renewable feed in, renewable product out. This illustration of a hydrotreating unit with a splitter visualizes how introducing renewable feedstock into your unit enables your production of a mix of fossil diesel and renewable diesel.
