METHOD OF MIXING GREENHOUSE GAS EMISSIONS FROM COASTAL THERMAL POWER STATIONS

Abstract: Exhaust gases from coastal thermal power plant boilers are increased in nitrous oxide content by catalytic converters and these modified stack gases are exhausted at a point just above the gloryhole spillway where they are sucked into the return high temperature seawater entering the spillway after the power plant cooling process. The greenhouse gas emissions are thus disposed in deep ocean sinks with the nitrous oxides in the seawater balancing the available phosphorous to promote marine growth.

Description: "METHOD OF MIXING GREENHOUSE GAS EMISSIONS FROM COASTAL THERMAL POWER STATIONS" Within the boilers, of coastal thermal power stations that produce Greenhouse Gas Emissions, catalytic converters are installed to prepare the Greenhouse Gas Emissions for disposal in the ocean. This disposal is both into the deep ocean sinks and by metabolism and photosynthesis of the dissolved gasses at the ocean surface. The catalytic converters modify the Greenhouse Gas Emissions by increasing the Nitrous Oxides in the exhaust gasses which when in solution are used to balance the available phosphorus in the ocean to promote maximum marine growth. The inlet flow of sea water used for cooling the thermal power station process is reduced so as to increase the outlet temperature in preparation for higher temperature mixing and dissolving the modified Greenhouse Gas Emissions. The modified Greenhouse Gas Emissions are made to flow from a low level on the exhaust stack to just above the glory hole spillway where they are sucked into the outlet flow of the higher temperature sea water entering the glory hole spillway used for cooling the coastal thermal power process. The glory hole spillway has a splitter wall to prevent vortex action at the intake and to ensure maximum discharge of the higher temperature sea water and modified Greenhouse Gas Emissions into the ocean. Downstream of the glory hole spillway vents are provided in the roof of the outlet tunnel. These vents allow excess Greenhouse Gas Emissions to be removed from the tunnel and be re-cycled into the intake of the glory hole spillway The mixing of gas and water is by the cascade action of the water entering the tunnel and by the stirring action of the flow within the tunnel due to the surface irregularities of the tunnel walls. Where cooling of the higher temperature sea water within the outlet tunnel is insufficient then the higher temperature sea water is reduced in temperature by mixing with sea water at ambient temperature at the discharge point to the outlet tunnel. The reduction in temperature is made to discharge sea water with dissolved Greenhouse Gas Emissions at the best temperature and location to promote marine growth. Undissolved Greenhouse Gas Emission are also discharged perpendicular to the prevailing ocean currents so that these undissolved Greenhouse Gas Emissions can be dissolved in the ocean as the Greenhouse Gas Emissions rise to the surface of the ocean.

Claims: The Claims defining the invention are as follows ;- 1. That this invention is defined by a reduction in the emission of greenhouse gases into the atmosphere by dissolving and including greenhouse gases in seawater for disposal in deep ocean sinks and by metabolism and photosynthesis of the dissolved gasses at the ocean surface. 2. That this invention is defined by using catalytic converters in the boilers to change of composition of the emission of greenhouse gas produced at coastal thermal power stations to match that required for disposal of greenhouse gases in deep ocean sinks and by disposal by metabolism and photosynthesis of the dissolved gasses at the ocean surface. 3. That this invention is defined by reducing the energy needed to generate power from coastal thermal power stations for the purpose of disposing greenhouse gas emissions.. The amount of inlet cooling water used is reduced to increase the temperature of the outlet water. This has three benefits. Firstly more gas is dissolved in the higher temperature water, secondly the size of the disposal tunnel is reduced and thirdly the warmer water rises to the surface for better metabolism and photosynthesis in the ocean 4. This invention is defined by using some or all of the methods of mixing that are available in the normal running of a power station (gloryhole spillway, tunnel and outlet works) but this invention uses those methods of mixing for the purpose of disposal of greenhouse gas emissions.
