DEVICE TO RECOVER VAPORS IN COMBUSTIBLE MATERIAL RESERVOIR (VERSIONS) Russian patent published in 2009 - IPC F17C3/00 B65D90/30 

FIELD: mechanics.

SUBSTANCE: proposed device comprises a pipeline with its inlet arranged in the reservoir vapor cushion and its outlet connected to the compressor inlet, the compressor outlet being connected, via a pipeline, with the inlet of sprayer arranged at the reservoir near-bottom part to feed vapors to combustible fluid, and differs in that the heat exchanger is mounted behind the compressor. The former and the latter are mounted outside or inside the reservoir. In compliance with the other version one end of the pipeline can be arranged in stored combustible fluid while its other end is connected to the pump inlet, the pump outlet being connected, via heat exchanger, to the ejector fluid inlet. Note that the ejector gas inlet can entrap vapor phase from the reservoir volume above the combustible fluid surface, while the ejector outlet can pump over combustible fluid containing dissolve vapors into reservoir fluid. The pump and ejector are located outside the reservoir. Note that the ejector gas inlet is connected, by additional pipeline, to the portion of volume, preferably above the stored combustible fluid surface.

EFFECT: reduced losses.
