A turbine outlet frozen gas capture apparatus, comprising: an enclosure divided into first and second chambers, the first chamber being receptive of turbine outlet exhaust including frozen gas; a wheel disposed and configured to be rotable such that each circumferential portion of the wheel sequentially moves into the first chamber and out of the second chamber and out of the first chamber and into the second chamber such that the frozen gas received in the first chamber is captured by the circumferential portions of the wheel in the first chamber and transported by the circumferential portions of the wheel into the second chamber; a wheel disposed and configured to be rotatable such that frozen gas received in the first chamber is captured and transported into the second chamber; a heater disposed within the second chamber and configured to vaporize the frozen gas transported therein to thereby produce vaporized gas; and a system configured to draw the vaporized gas from the second chamber and to prevent flow of the turbine outlet exhaust from the first chamber into the second chamber in accordance with a pressure differential between the first and second chambers, the system comprising: a compressor fluidly interposed between the second chamber and a vaporized gas outlet, the compressor being configured to draw the vaporized gas from the second chamber toward the vaporized gas outlet; and a controller configured to measure a differential pressure between the first and second chambers, the controller being coupled to the compressor and configured to control an operation of the compressor in accordance with the differential pressure. an enclosure divided into first and second chambers, the first chamber being receptive of turbine outlet exhaust including frozen gas; a wheel disposed and configured to be rotable such that each circumferential portion of the wheel sequentially moves into the first chamber and out of the second chamber and out of the first chamber and into the second chamber such that the frozen gas received in the first chamber is captured by the circumferential portions of the wheel in the first chamber and transported by the circumferential portions of the wheel into the second chamber; a wheel disposed and configured to be rotatable such that frozen gas received in the first chamber is captured and transported into the second chamber; a heater disposed within the second chamber and configured to vaporize the frozen gas transported therein to thereby produce vaporized gas; and a system configured to draw the vaporized gas from the second chamber and to prevent flow of the turbine outlet exhaust from the first chamber into the second chamber in accordance with a pressure differential between the first and second chambers, the system comprising: a compressor fluidly interposed between the second chamber and a vaporized gas outlet, the compressor being configured to draw the vaporized gas from the second chamber toward the vaporized gas outlet; and a controller configured to measure a differential pressure between the first and second chambers, the controller being coupled to the compressor and configured to control an operation of the compressor in accordance with the differential pressure. a compressor fluidly interposed between the second chamber and a vaporized gas outlet, the compressor being configured to draw the vaporized gas from the second chamber toward the vaporized gas outlet; and a controller configured to measure a differential pressure between the first and second chambers, the controller being coupled to the compressor and configured to control an operation of the compressor in accordance with the differential pressure.
