Epcon is proud to share its case study for the Tank Truck Loading Terminal.
Loading and Unloading Tank Trucks:
When the Tank Trucks are unloaded, it causes a lot of vapor to be released to atmosphere. These emissions have to be controlled and can not be released to atmosphere.
Generally speaking, with the loading and unloading of truck terminals there are multiple loading and unloading stations. At a given time, one, two or three, or as many as eight tank cars can be loaded or unloaded. In the past, archaic Open Flare technology was used.
Flares are extremely inefficient and there is no guarantee of Destruction Removal Efficiency (DRE). Additionally, there was a good portion of unburned fuel in this major Tank Truck operation. This particular application was located in a residential area where there were also a lot of chlorinated hydrocarbons.
These operations have been prone to a large number of explosions and accidents because of the high exothermic heat release and sudden heating of the system. The fire will travel to and destroy the terminal.
This particular customer came to Epcon and discussed various technologies and we offered a large capacity RTO which automatically detected and increased in capacity when the high-concentration vapor was introduced. Until then, Regenerative Thermal Oxidizer (RTO) technology had never been used at Tank Terminals.
Because of the high Heat Exchanger efficiency, the fuel consumption always stayed the same.
For upset conditions, Epcon provided a High-Solvent Bypass as a Heat Release.
