Abstract
A method and a system for supplying pressurized gas from a liquefied-gas (LG) storage tank, the method including the steps of: (a) providing a system including: (i) a storage tank for storing liquefied gas, the tank having a lower liquid region and a vapor region thereover; (ii) a heat exchanger external to the storage tank; (iii) pumping means driven by a liquid; (iv) a line for directly transferring the vaporized gas from the heat exchanger to the consumer; (b) pumping at least a portion of the liquefied gas from the lower region to the heat exchanger using the pumping means; (c) heating the liquefied gas in the heat exchanger to produce the vaporized gas; and (d) supplying the vaporized gas directly to the consumer, according to consumer demand.
Claims28
A method for supplying vaporized gas to a consumer, the method comprising the steps of:
- (a) providing a system including:
- (i) a storage tank for storing liquefied gas, said tank having a lower liquid region and a vapor region thereover;
- (ii) a heat exchanger external to said storage tank;
- (iii) pumping means driven by a liquid;
- (iv) a line for directly transferring the vaporized gas from said heat exchanger to the consumer;
- (b) pumping at least a portion of said liquefied gas from said lower region to said heat exchanger using said pumping means;
- (c) heating said liquefied gas in said heat exchanger to produce the vaporized gas;
- and
- (d) supplying the vaporized gas directly to the consumer, according to consumer demand.
A system for supplying vaporized gas to a consumer, the system comprising:
- (a) a storage tank for storing liquefied gas, said tank having a lower liquid region and a vapor region thereover;
- (b) a heat exchanger external to and fluidly communicating with said storage tank, within which heat exchanger, a heat exchange liquid and said liquefied gas come into indirect heat-exchange relation;
- (c) pumping means, driven by a liquid, for pumping at least a portion of said liquefied gas from said storage tank through said heat exchanger;
- (d) a gas supply line, operatively connected to said heat exchanger, for directly transferring the vaporized gas from said heat exchanger to the consumer upon demand;
- and
- (e) a control system associated with said heat exchanger and configured to control a rate of heat supply to said liquefied gas so as to vaporize the liquefied gas.
