Co2 t s diagram. T s diagram of s co 2 recompressing cycle. The area under a process curve on a t s diagram is related to the amount of heat transferred to the gas. As a large amount of heat is recovered in recuperators to increase the thermal efficiency high effectiveness is required and therefore the capital cost increases when. An enthalpy entropy chart also known as the h s chart or mollier diagram plots the total heat against entropy describing the enthalpy of a thermodynamic system.

Experimental investigation of the s co2 condensing cycle united states. For reversible ideal processes the area under the t s. It is possible to perform a series of processes in which the state is changed during each process but the gas eventually returns to its original state. Fluor econamine sm technology using diglycolamine.

A typical chart covers a pressure range of 0 01 1000 bar and temperatures up to 800 degrees celsius.

Table a 20 ideal gas properties of carbon dioxide co 2 table a 21 ideal gas properties of carbon monoxide co table a 22 ideal gas properties of hydrogen h 2 table a 23 ideal gas properties of water vapor h 2 o. A temperature entropy diagram or t s diagram is a thermodynamic diagram used in thermodynamics to visualize changes to temperature and specific entropy during a thermodynamic process or cycle as the graph of a curve it is a useful and common tool particularly because it helps to visualize the heat transfer during a process.

S co 2 supercritical co 2. An isentropic process appears as a vertical line on a t s diagram. The current refrigerant r134a has a global warming potential gwp of 1300 with respect to co2. Figure a 9 t s diagram for water figure a 10 mollier diagram for water.

It shows enthalpy in terms of internal energy pressure and volume using the relationship or in terms of specific. Carbon capture or co 2 capture is the process of capturing carbon dioxide from flue gases produced by fossil fuel power plants refineries and chemical plants. There is currently serious consideration of replacing it with r744 carbon dioxide in refrigeration and heat pump applications as well as automotive air conditionong systems.
