researched on non-catalytic pyrolysis of ethane to ethylene in the presence of CO 2 with or without limited CO 2. A large amount of polyethylene is used for producing plastics which contains polymer chains of ethylene units in its numerous chain lengths. having a high market demand with production rate of 150,000,000 tons/year and this production rate has been predicted to rise by 3.5 percent in the next five years. Polyethylene is used as starting material for the production products such as: cosmetics, plastics, solvents etc. Polyethylene has been extensively applied in industries chemicals and other related products are been manufactured all round the world. Olefins manufacturing is the third largest petrochemical industry after others like ammonia manufacturing and petroleum refining.
#Aspen plant simulation series
The effect of reactor size and number showed that At 90% conversion the multiple CSTRS in series gave a lower volume than the single CSTR for the same conversion, and more Economical than the single CSTR for the same conversion. The sizing results for each of the five compressors were also compared in terms of the following parameters: Adiabatic Head, Polytropic Head, Adiabatic fluid Head, polytropic Fluid Head, Adiabatic Efficiency, power consumed, polytropic head factor, polytropic exponent and isentropic exponent. The design results of the sizing parameters for the Multiple and single CSTRs were compared in terms of Volume, Diameter, Height, Spacetime, Space Velocity, and Volumetric flowrate respectively. The results of the material and energy balance of the various components of the plant were performed manually and with Hysys which showed a maximum deviation of 0.8%. The effect of reactor size and number on polyethylene output was studied by simulating the plant with five continuous stirred tank reactors (CSTRs) in series and a single reactor. The polyethylene reactor was simulated to study the effect of process functional parameters such as reactor dimensions, temperature and pressure.
The design of the various components of the Hysys model was performed. A material and energy balance for the various components of the plant was performed manually and with Hysys for comparison. A Hysys model of the polyethylene was developed using the polyethylene plant layout of Indorama Eleme Petrochemical Company. The simulation of a 270 KTA capacity polyethylene plant was performed using Aspen Hysys version 8.8.
