How to utilize flue gases in polymerization process

In polymerization process there are many possible options for energy conservation efficiency improvement. In this article the opportunity for energy savings using flue gas heat recovery is presented. Based on process data for each operation in low density polyethylene (LDPE) production the fuel saving as well as thermal environmental protection are curried out. From first established baseline energy requirement the option for reduce energy consumption is shown as follow. The applying of flue gasses for combustion air preheating natural gas saving is 7.95%. At the same time the environment thermal load is lowering from 2300C to 68.110C. The best results show the flue gas recovery in combination for air and feed water preheating. The natural gas saving becomes 11.7%, while outlet temperature of flue gasses is reduced from 2300C to 26.20C.
