Removal of non-condensable gases from a closed loop process
A method which allows the ejection of non-condensable gases, notably air, from a closed loop power generation process or heat pump system, is disclosed. A vessel in which a working fluid is absorbed or condensed can be separated from the power generation processes by valves. Residual gas comprising C02, non-condensable gas such as air, water and alkaline materials including amines may be compressed by raising the liquid level in said vessel. The concurrent pressure increase leads to the selective absorption of C02 by alkaline materials. In simpler embodiments, mainly air is removed from one- or two-component processes. Following the compression, non-condensable gas may be vented, optionally through a filter. The method is simple and economic as vacuum pumps may be omitted. The method is useful for any power generation and Rankine cycle, and particularly useful for the power generation process known as C3 or Carbon Carrier Cycle.

This is preferably done at times of high electricity demand and high electricity prices. Further, the method may be used for quick power grid regulation, i.e. on the scale of less than one minute. The method is simple and economic as storage of hot water or hot liquid is inexpensive. Preferred heat sources are industrial plants for paper, aluminium or steel production, geothermal heat sources, district heating networks or solar heat. The method is particularly useful for the power generation process known as Carbon Carrier Cycle.
Expansion machines in thermodynamic cycles operate at low pressures, i.e. below 10 bar. The interplay among components including gas generator, expansion machine, heat exchangers and pressure reduction device (absorber or condenser) is optimized, resulting in configurations operating at the lowest achievable cost level. A single stage radial turbine characterized by a pressure ratio of 5-10, a dimensionless speed of about 0.7 and a loading coefficient of 0.7 is a preferred expansion machine for certain thermodynamic cycles involving CO2 gas to permit such radial turbines to operate close to their optimum design specification and highest efficiency level. Methods to handle liquids which may condense within or inside the turbine are also disclosed, as well as methods to handle axial pressure on bearings and methods to protect lubricant in bearings.

REMOVAL OF NON-CONDENSBLE GASES FROM A CLOSED LOOP PROCESS
A method which allows the ejection of non-condensable gases, notably air, from a closed loop power generation process or heat pump system, is disclosed. A vessel in which a working fluid is absorbed or condensed can be separated from the power generation processes by valves. Residual gas comprising C02, non-condensable gas such as air, water and alkaline materials including amines may be compressed by raising the liquid level in said vessel. The concurrent pressure increase leads to the selective absorption of C02 by alkaline materials. In simpler embodiments, mainly air is removed from one- or two- component processes. Following the compression, non-condensable gas may be vented, optionally through a filter. The method is simple and economic as vacuum pumps may be omitted. The method is useful for any power generation and Rankine cycle, and particularly useful for the power generation process known as C3 or Carbon Carrier Cycle.

AN IMPROVED THERMODYNAMIC CYCLE OPERATING AT LOW PRESSURE USING A RADIAL TURBINE
This invention concerns useful expansion machines in thermodynamic cycles operating at low pressures, i.e. below 10 bar maximum pressure. In order to be commercially competitive, any component of a thermodynamic cycle needs to operate as close as possible to maximum performance level. In an iterative process, the interplay between components including gas generator, expansion machine, heat exchangers and pressure reduction device (absorber or condenser) is optimized, resulting in configurations operating at the lowest achievable cost level. Surprisingly, it was found that a single stage radial turbine characterized by a pressure ratio of 5-10, a dimensionless speed of about 0.7 and a loading coefficient of 0.7 is the highly preferred expansion machine for the C3 thermodynamic Climeon cycle and its variations, e.g. involving CO2 gas as working fluid and amines as reversible, temporary CO2 absorbents as disclosed earlier, or other working fluids. In other words, surprisingly, the disclosed processes for energy generation allow such radial turbines to operate close to their optimum design specification and highest efficiency level. Methods to handle liquids which may condense within or inside the turbine are also disclosed, as well as methods to handle axial pressure on bearings and methods to protect lubricant in bearings.
