QHT integration in petrochemi-cal 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.
Steam cracking
Steam crackers are designed to be highly energy efficient because they are large energy consumers. QHT tech can raise their efficiency even further. One of the largest European ethylene producers is investigating how Qpinch can help to recover waste heat from the oil quench. In addition, pyrolyisis gasoline aromatic extraction presents another attractive case.
Para xylene extraction
It is common knowledge that para xylene extraction from reformate splitter bottoms is an extremely heat consuming technology. Despite the intense heat integration, there still is significant waste heat production. Recovering this waste heat and transforming it into valuable process heat, is calculated to have an IRR of >20 %
Distillation
In chemical productions, distillation is frequently used to recover the latent heat from the overhead stream. An Antwerp based partner, is operating a Qpinch chemical heat transformer to recover the waste heat from the overhead condensors and convert it to valuable process steam.
Case Study: Distillation columns
The QHT installation can improve the energy efficiency of your distillation columns by 50%. The bottom of distillation column is heated to process temperature for their operation. We are using the waste heat from the column overheads to reinfuse it in the heating process of the column bottom.
