Turbine outlet frozen gas capture apparatus and method

A turbine outlet frozen gas capture apparatus, comprising:

• an enclosure;
• a divider disposed to define in the enclosure first and second chambers, the first chamber being receptive of turbine outlet exhaust including frozen gas;
• a wheel disposed to straddle the divider and configured to be rotatable such that frozen gas received in the first chamber is captured by the wheel and transported by wheel rotation 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 maintain a pressure differential between the first and second chambers sufficient to prevent flow of the turbine outlet exhaust across the divider.

A turbine outlet frozen gas capture method, comprising:

• receiving turbine outlet exhaust including frozen gas within a first chamber of an enclosure divided into the first chamber and a second chamber;
• capturing the frozen gas in the first chamber and transporting the captured frozen gas into the second chamber;
• heating the frozen gas in the second chamber to produce vaporized gas;
• and
• drawing the vaporized gas from the second chamber and maintaining a pressure differential between the first and second chambers sufficient to prevent flow of the turbine outlet exhaust from the first chamber to the second chamber.
