Abstract:
This assembly is an apparatus for recovering vapors during the dispensing of fluids from a storage tank to a receiving tank. More specifically, the assembly reduces odors from storage tanks and loading facilities at asphalt terminals. A dual carbon system was installed for the tanks and the loading rack. The system was operated continuously at a low flow rate to handle stray vapors from the tanks when they are not being filled. The system would be turned to a high flow rate whenever the tanks are receiving product. The blowers on this system are run at a speed proportional to the number of loading arms being used, based on vacuum transmission.
