Propane Drives Turbine To Harness Waste Heat, Reduce Pollution ... A new patent pending technology is available which replaces the steam turbine system with a Cascading Closed Loop Cycle (CCLC) system producing an increase in MW output of 150% to 600% over a steam turbine system operating at the same heat source temperatures. Click here for comparison chart. The CCLC can also be installed to operate in conjunction with an existing steam turbine system to increase the output by 100% without using additional fuel, the Super CCLC system. If the CCLC turbine system had been installed in place of or with the steam turbines in use today, it is estimated that the U.S. economy could save $100 billion in fuel costs annually. ... The CCLC system is so efficient that during the process of converting waste heat to power, it reduces the flue gas temperature to near ambient where conditions are favorable for elimination of pollutants. At these temperatures, vaporized pollutants such as Mercury, Vanadium, Lead, Cadmium, as well as Vaporized Organic Compounds (VOC), can no longer exist in a vaporized state and are �forced� to condense out of the flue gas as a liquid or solid. The remaining SOx and NOx can be removed using a low temperature Final Flue Gas Cleanup (FFGC) system by circulating a dilute water solution of sodium hydroxide and hydrogen peroxide in a scrubber that reacts with any remaining SOx and NOx to form stable salt solutions. The dilute solution also serves to remove PM2.5 and PM10 particulates, returning the flue gas to the environment in a pristine state. ... Propane is not consumed in the process and serves only as the medium to convert thermal energy to mechanical energy; requiring only 130 Btu/lb to vaporize versus 1000 Btu/lb for water. More importantly, propane will vaporize and absorb superheat at low ambient temperatures � not possible with water.
