THERMODYNAMIC PLANT OPTIMIZATION FOR THE PRODUCTION OF CARBON ACID AS AN ELEMENT OF TRIGENERATING TURBO UNIT ON THE ORGANIC RENKIN CYCLE
The exergy analysis of the installation for the production of liquid and gaseous carbon dioxide has been done with the possibility of obtaining a cold in the trigeneration scheme. The cycle in P-h-coordinates of the given setup is presented. The Grassmann-Shargut diagram of the installation for the production of carbon dioxide was constructed. It was revealed that with the help of an additional element in the form of an external cooling source (a circulating water supply system with a cooling tower, or cold water supplied to the object from surface or underground sources), it is possible to significantly reduce the consumption of the working fluid in the installation and, as a consequence, losses in the cycle. The designed Grassmann-Shargut diagrams of the initial and modified plant diagrams showed that this measure allows reducing the exergy costs for the compressor drive to 2.97%.
