Abstract
A trans-critical thermodynamic system includes an expansion device and a separator. The expansion device receives a supercritical fluid containing solutes. The expansion device is operable to expand the supercritical fluid to produce a sub-critical gas by reducing a temperature and/or a pressure of the supercritical fluid. The separator removes the solutes from the sub-critical gas.
Claims13
A trans-critical thermodynamic system, comprising:
- an expansion device configured to receive a supercritical fluid containing solutes, the expansion device operable to expand the supercritical fluid to produce a sub-critical gas by reducing a temperature and/or a pressure of the supercritical fluid;
- a separator configured to remove the solutes from the sub-critical gas;
- a high pressure circuit configured for the supercritical fluid to flow therethrough;
- and
- a fluid extraction point operable to extract a portion of the supercritical fluid from the high pressure circuit, wherein the expansion device is operable to expand the portion of the supercritical fluid.

A method of removing solutes from a working fluid in a trans-critical circuit, the method comprising:
- identifying a position in the trans-critical circuit where the working fluid is a sub-critical gas;
- positioning a separator such that the separator receives at least a portion of the working fluid when the working fluid is the sub-critical gas, the separator operable to remove solutes from the sub-critical gas,
- identifying a fluid extraction point in the trans-critical circuit where the working fluid is a supercritical fluid;
- extracting a portion of the supercritical fluid from the fluid extraction point in the trans-critical circuit;
- and
- passing the portion of the supercritical fluid through an expansion device such that the portion of the supercritical fluid becomes the sub-critical gas.
