Refineries
Improving refinery industry margins with waste heat recovery
The extensive refinery processing infrastructure is rich in opportunities for energy efficiency improvement. QHT tech reduces your OpEx to the point of actual value generation, which supports your other abatement investments.

QHT integration in refinery operations
We have highlighted some examples that are relevant to refinery process activities.
It is clear that every plant has other essentials and priorities. We are keen to help you evaluate the potential of your particular infrastucture. Provide us with the specifics of your situation.

Diesel hydrotreater
In the diesel hydrotreater stripper, light fractions are separated from the desulfurized product. The overhead of this stripper and the diesel product are currently condensed or air-cooled. In this stage a QHT installation can recover waste heat and transform it to process heat.

Reformate splitter
A reformate splitter is a distillation column where the overhead is cooled to the environment. This represents a heat energy loss that can be recovered with a QHT installation and transformed into process heat.

Fluid catalytic cracking
Three waste heat streams are available for energy recovery in each FCC unit: main fractionator overhead condenser, light cycle oil cooler, slurry cooler. Any of these waste heats can be captured by a QHT installation and lifted to industry standard process heat.

Case Study: Fluid catalytic cracking
In this example, hot water is generated by recovering the latent heat from the main fractionator overhead stream and by cooling down a number of side streams such as the light cycle oil (LCO). Pay back times are calculated to be less than 4 years if the alternative is a natural gas boiler with natural gas priced at 50 €/MWh and CO2 at 80 €/ton

Why QHT technology is the best first step on the road to net-zero for your refinery plant.
