Abstract
A method of and apparatus for transferring gas. The method comprising expanding a process gas 101 having a first temperature to produce a first volume of the process gas that has a second temperature that is greater than the first temperature, and a second volume of the process gas that has a third temperature that is less than the first temperature. The method further comprises displacing at least some of the second volume of the process gas 102 into the receiving vessel using a piston gas, wherein the piston gas is of the same type as the process gas.

A method of transferring gas, comprising:
- expanding a process gas having a first temperature to produce a first volume of the process gas that has a second temperature that is greater than the first temperature, and a second volume of the process gas that has a third temperature that is less than the first temperature;
- and
- displacing at least some of the second volume of the process gas into a receiving vessel using a piston gas, wherein the piston gas is of the same type as the process gas.
An apparatus for transferring gas to a receiving vessel, the apparatus comprising:
- an auxiliary vessel for containing an auxiliary gas;
- a first vessel;
- and
- a second vessel selectively fluidly connectable to the first vessel;
- and;
- wherein the first vessel comprises an opening selectively fluidly connectable to a receiving vessel;
- wherein the first vessel is selectively fluidly connectable to the auxiliary vessel such that the auxiliary gas may flow from the auxiliary vessel into the first vessel without passing through the second vessel.
