PLANT FOR FILLING BOTTLES AND VESSELS WITH LIQUEFIED GAS Russian patent published in 2003 - IPC

FIELD: gas technological equipment. SUBSTANCE: proposed plant includes reservoir for liquefied gas, system for displacement of liquefied gas from reservoir by natural gas made in form of bottle unit connected with reservoir by means of pipe line fitted with shut-off valve and pressure reducer. Reservoir for liquefied gas consists of inner and outer vessels of similar gas-tightness, fire resistance and strength. Interwall space is used for mounting the pressure gauge and is filled with fire-resistant material at low heat conductivity, for example swollen vermiculite or swollen perlite sand. Inner vessel of reservoir is provided with impact dampening device made in form of transversal baffles dividing it into sections. Ratio of volume of reservoir and volume of natural gas bottle unit is determined from the following inequality: where V_b - is total geometric volume of bottle unit; V_V is geometric volume of inner vessel of reservoir; K₁ = P_l.g.max/P_n.g.max; K₂ = V_f/V_V; P_l.g.max is maximum pressure of liquefied gas; P_n.g.max is maximum pressure of natural gas and V_f is volume of filling of inner vessel with liquefied gas. EFFECT: enhanced operational and ecological safety; maintainability; enhanced efficiency. 1 dwg
