A model was developed to identify the process modifications required to reduce the energy consumption of the cold box of an olefins plant, and maximize the efficiency of the integrated refrigeration system. The model was applied to a process producing 500,000 ton/yr of ethylene. The targeted energy savings were in the order of magnitude of 37%, with 24% resulting from the optimization of flow rates in the refrigeration system, and 13% resulting from the valorization of the off-streams of the process. This targeting tool was used to identify ways to improve the rational use of energy in the process, as well as technological solutions that reduce the mechanical power consumption of the refrigeration system.

Abstract
A model was developed to identify the process modifications required to reduce the energy consumption of the cold box of an olefins plant, and maximize the efficiency of the integrated refrigeration system. The model was applied to a process producing 500,000 ton/yr of ethylene. The targeted energy savings were in the order of magnitude of 37%, with 24% resulting from the optimization of flow rates in the refrigeration system, and 13% resulting from the valorization of the off-streams of the process. This targeting tool was used to identify ways to improve the rational use of energy in the process, as well as technological solutions that reduce the mechanical power consumption of the refrigeration system.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
