BREATHING SYSTEM OF RESERVOIR FOR HIGHLY VOLATILE LIQUIDS Russian patent published in 2002 - IPC

FIELD: petrochemical industry. SUBSTANCE: proposed breathing system has condenser with fitted-on gas-collector. Condenser communicates with reservoir. Adsorber with sorbent grains is installed on condenser. Heat exchanger in form of flat bank of thermocells is located between condenser and adsorber. Its cold junctions are pointed to condenser, and hot ones, to adsorber. Branch pipe for communicating condenser with adsorber and with atmosphere is installed on adsorber. Gas collector is made of high-porosity permeable cellular material. Cellular material used in system has porosity of 85 - 97%, with diameter of pores 0.5 - 4.5 mm. Adsorber from side of hot junction of thermocell is provided with plate made of high-porosity permeable cellular material. Vertical holes of diameter exceeding diameter of pores of high-porosity permeable cellular material can be made in gas collector and plate. EFFECT: increased efficiency of condensing of highly volatile liquid vapors, reduced ejection of vapors into atmosphere. 3 cl, 2 dwg
