Abstract
A fluid dispensing system may include a first tank configured to contain a first fluid and a second tank configured to contain a second fluid. The system may also include a conditioning system fluidly connected to the second tank. The conditioning system may include at least one conduit fluidly coupled to a lower region of the second tank. The conditioning system may also include a heat exchanger. In addition, the conditioning system may include at least one conduit fluidly coupled to an upper region of the second tank.
Claims17
A fluid dispensing system, comprising:
- a first tank configured to contain a first fluid;
- a second tank configured to contain a second fluid;
- a plurality of conduits fluidly connecting the first and second tanks, wherein the first tank gravity-feeds or pressure-feeds the first fluid to the second tank;
- and
- a conditioning system fluidly connected to the second tank, wherein the conditioning system comprises:
- a heat exchanger;
- a first conduit fluidly coupled to a lower region of the second tank and extending from the lower region of the second tank to the heat exchanger;
- a second conduit fluidly coupled to an upper region of the second tank and extending from the heat exchanger to the upper region of the second tank;
- and a third conduit fluidly coupled to the lower region of the second tank and extending from the heat exchanger to the lower region of the second tank, wherein the conditioning system receives the second fluid from the second tank via the first conduit and switches between of a first configuration that returns the second fluid from the heat exchanger to the lower region of the second tank via the third conduit, and a second configuration that returns the second fluid from the heat exchanger to the upper region of the second tank via the second conduit.
6 more elements
An LNG dispensing system, comprising:
- a control system including a programmable logic controller;
- a first tank configured to contain LNG;
- a second tank configured to contain LNG, wherein the first tank is positioned so that a bottom region of the first tank is positioned above an upper region of the second tank;
- a plurality of conduits fluidly connecting the first and second tanks, wherein the first tank gravity-feeds or pressure-feeds the LNG in the first tank or pressure-fed to the second tank;
- at least one measuring device for measuring at least one property of the LNG, wherein the at least one measuring device is operatively coupled to the second tank;
- and
- a conditioning system fluidly connected to the second tank, wherein the conditioning system comprises:
- a heat exchanger, wherein the heat exchanger includes a vaporizer to at least partially vaporize the LNG passed through it;
- at least one conduit fluidly coupled to a lower region of the second tank and extending from the lower region of the second tank to the heat exchanger;
- at least one conduit fluidly coupled to an upper region of the second tank and extending from the heat exchanger to the upper region of the second tank;
- and at least one third conduit fluidly coupled to the lower region of the second tank and extending from the heat exchanger to the lower region of the second tank, wherein the conditioning system receives the LNG from the second tank via the at least one first conduit and switches between a first configuration for saturating the LNG in the second tank that removes a portion of the LNG from the second tank via the at least one first conduit and returns the at least partially vaporized LNG from the heat exchanger to the lower region of the second tank via the at least one third conduit, and a second configuration for pressurizing the LNG in the second tank that removes a portion of the LNG from the second tank via the at least one first conduit and returns the at least partially vaporized LNG from the heat exchanger to the upper region of the second tank via the at least one second conduit.
