Abstract

The invention primarily concerns a facility for storing and cooling a liquefied gas, for example a liquefied natural gas, the facility comprising at least one tank configured to contain the liquefied gas, a closed cooling circuit configured to be supplied with liquefied gas in the liquid state coming from the tank, at least one injection member configured for reinjecting cooled liquefied gas into the tank, the facility being characterized in that it comprises at least one connection line configured to recover a cooled gas from at least one remote container that is separate and independent from the facility.

First claim

What is claimed is:

1. A method of using a facility for storing and cooling a liquefied gas, comprising the steps of:
providing a facility comprising:
at least one tank configured to contain liquefied gas, said tank comprising at least one lower region adapted and configured to contain the liquefied gas in the liquid state, and at least one upper region adapted and configured to contain the vapors of the liquefied gas;
at least one closed cooling circuit adapted and configured to be supplied with liquefied gas in the liquid state coming from the tank, the cooling circuit comprising at least one compressor adapted and configured to compress a cycle gas, at least one engine, at least one turbine, and at least one first heat exchanger adapted and configured to generate a heat exchange between the liquefied gas in a liquid state coming from the tank and the cycle gas so as to cool the liquefied gas coming from the tank when the facility is in operation;
at least one injection component fluidly connected to the cooling circuit via an injection pipe, the injection component being adapted and configured to reinject the cooled liquefied gas into the tank; and
at least one connection line adapted and configured to recover a gas to be cooled from at least one remote container, which is separate and independent from said facility, said at least one connection line being fluidly connected to the tank of the facility, wherein the engine is mechanically connected to the compressor in order to drive the compressor and also to the turbine so that the turbine drives the engine;

at least partially receiving liquefied gas coming from a first remote container, which is separate and independent from the facility, via the connection line that fluidly connects the at least one tank to the remote container, the first remote container being separate and independent from the facility;
supplying the cooling circuit with liquefied gas coming from the tank;
cooling the liquefied gas coming from the tank with the cooling circuit; and
injecting the cooled liquefied gas into the tank with the injection component;
transferring at least some of the cooled liquefied gas to the remote container with the injection pipe; and
transferring cooled liquefied gas remaining in the at least one tank to one or more empty remote containers which are separate and independent from the facility.

2. A method of using a facility for storing and cooling a liquefied gas, comprising the steps of:
providing a first facility comprising:
at least one tank configured to contain liquefied gas, said tank comprising at least one lower region adapted and configured to contain the liquefied gas in the liquid state, and at least one upper region adapted and configured to contain the vapors of the liquefied gas;
at least one closed cooling circuit adapted and configured to be supplied with liquefied gas in the liquid state coming from the tank, the cooling circuit comprising at least one compressor adapted and configured to compress a cycle gas, at least one engine, at least one turbine, and at least one first heat exchanger adapted and configured to generate a heat exchange between the liquefied gas in a liquid state coming from the tank and the cycle gas so as to cool the liquefied gas coming from the tank when the facility is in operation;
at least one injection component fluidly connected to the cooling circuit via an injection pipe, the injection component being adapted and configured to reinject the cooled liquefied gas into the tank; and
at least one connection line adapted and configured to recover a gas to be cooled from at least one remote container, which is separate and independent from said facility, said at least one connection line being fluidly connected to the tank of the facility, wherein the engine is mechanically connected to the compressor in order to drive the compressor and also to the turbine so that the turbine drives the engine;

providing a second facility comprising:
at least one tank configured to contain liquefied gas, said tank comprising at least one lower region adapted and configured to contain the liquefied gas in the liquid state, and at least one upper region adapted and configured to contain the vapors of the liquefied gas;
at least one closed cooling circuit adapted and configured to be supplied with liquefied gas in the liquid state coming from the tank, the cooling circuit comprising at least one compressor adapted and configured to compress a cycle gas, at least one engine, at least one turbine, and at least one first heat exchanger adapted and configured to generate a heat exchange between the liquefied gas in a liquid state coming from the tank and the cycle gas so as to cool the liquefied gas coming from the tank when the facility is in operation;
at least one injection component fluidly connected to the cooling circuit via an injection pipe, the injection component being adapted and configured to reinject the cooled liquefied gas into the tank; and
at least one connection line adapted and configured to recover a gas to be cooled from at least one remote container, which is separate and independent from said facility, said at least one connection line being fluidly connected to the tank of the facility, wherein the engine is mechanically connected to the compressor in order to drive the compressor and also to the turbine so that the turbine drives the engine, at least one of the at least one tank of the second facility being empty;

at least partially receiving liquefied gas coming from a first remote container, which is separate and independent from the first and second facilities, via the connection line that fluidly connects the at least one tank of the first facility to the first remote container, the first remote container being separate and independent from the facility;
supplying the cooling circuit of the first facility with liquefied gas coming from the tank of the first facility;
cooling the liquefied gas coming from the tank of the first facility with the cooling circuit of the first facility, thereby producing cooled liquefied gas; and
injecting the cooled liquefied gas into the tank of the first facility with the injection component of the first facility;
transferring at least some of the cooled liquefied gas to the first remote container with the injection pipe of the first facility; and
transferring cooled liquefied gas remaining in the first remote container to the at least one empty tank of the second facility.

3. A method of using a facility for storing and cooling a liquefied gas, comprising the steps of:
providing a facility comprising
at least one tank configured to contain liquefied gas, said tank comprising at least one lower region adapted and configured to contain the liquefied gas in the liquid state, and at least one upper region adapted and configured to contain the vapors of the liquefied gas;
at least one closed cooling circuit adapted and configured to be supplied with liquefied gas in the liquid state coming from the tank, the cooling circuit comprising at least one compressor adapted and configured to compress a cycle gas, at least one engine, at least one turbine, and at least one first heat exchanger adapted and configured to generate a heat exchange between the liquefied gas in a liquid state coming from the tank and the cycle gas so as to cool the liquefied gas coming from the tank when the facility is in operation;
at least one injection component fluidly connected to the cooling circuit via an injection pipe, the injection component being adapted and configured to reinject the cooled liquefied gas into the tank; and
at least one connection line adapted and configured to recover a gas to be cooled from at least one remote container, which is separate and independent from said facility, said at least one connection
