The industry has always looked at methods to optimize production, reduce film or fiber This excess of water helps to reduce The glycol yield is 99–99.5%, with other glycols practically absent. This is done by coal gasification. PRODUCTION OF ETHYLENE GLYCOL Manufacturing process Discrimination The different processes followed for the production of ethylene glycol includes: Ethylene carbonate process: In this method, ethylene oxide is converted to an intermediate, ethylene carbonate, by reaction with carbon dioxide, which is then hydrolyzed by water to give ethylene glycol. Coal Gasification: The first step in the produ ction of ethylene glycol from coal, is the production of. The RfD is an estimate (with … In order to produce 203.58 kgmol/hr of Ethylene Glycol, the flow rate of the reactant that we need to obtain the desired product is shown below : Ethylene Glycol production rate = 203.58 43 CHAPTER 2 PROCESS MODELING AND FLOWSHEETING 2.1 Introduction The process overview 144 0 obj <> endobj �����F�С΁,G�� d�]�� �i�U�sZ4�sTM���������$��:h��������G��)�����0�~#�$u�@.�c,�pTw. •Since EO is very reactive and hazardous to … Ethylene glycol is a high-production-volume chemical; it breaks down in air in about 10 days and in water or soil in a few weeks. 168 0 obj <]/Info 143 0 R/Filter/FlateDecode/W[1 3 1]/Index[144 42]/DecodeParms<>/Size 186/Prev 1204301/Type/XRef>>stream %PDF-1.6 %���� endstream endobj 148 0 obj <>stream Ethylene glycol production The aqueous EO solution from the ethylene oxide production section is sent to the gylcol section.
