This paper proposes switching tank sets to combined regasification so as to reduce the energy consumption in artificial regasification systems. To that end, a tank set must be equipped with a special valve to sustain a pressure of 0.135 MPa in vapor blankets. This valve will trigger alternating draft of liquid and vapor phases of liquefied petroleum gases so as to maximize the utilization of the natural evaporating capacity of feed tanks. To make the proposed solution scientifically sound, the research team has developed a mathematical model of combined regasification of liquefied petroleum gases, which integrates the two basic periods of tank-set operation: natural regasification in the feed tank, and artificial gasification in the evaporator. In order to validate the proposed model, a pilot set was used for experimentation. The obtained experimental data correlate well with the numerical output of the proposed model, making it recommendable for engineering practice. Studies show that implementing combined regasification in liquefied gas tanks will considerably reduce the energy costs of evaporating gas, making the liquefied gas supply systems much more energy-efficient and cost-effective.
