Heating operations are frequently used in process industry on various installations (such as reactors, vessel, etc.). The following photo presents a high temperature reactor.
VOC emissions during heating phase can be determined with this heating model, which gives good results when the temperature increase is significant and approaches the boiling point.
A 7.5 m3 reactor contains 5 m3 of a solvent mixture with the following composition (in mass fraction):
The solvent mixture is heated from 20 to 70°C and the reactor is vented to atmosphere during the heat up operation.
Total emissions calculated during this heating operation are: 2.137 kg of VOC.
For each product emission is:
