Modelling and Simulation of Dissolution/Reprecipitation Technique for Low-Density Polyethene Using Solvent/Non-Solvent System
نویسندگان
چکیده
The global production and consumption of plastics have continued to increase. Plastics degrade slowly, causing persistent environmental pollution Developed waste plastic recycling methods are discussed in this report, with a focus on the dissolution/reprecipitation technique restore low-density polyethene (LDPE) wastes. Aspen HYSYS is used simulate LDPE. Turpentine/petroleum ether (TURP/PetE) chosen as solvent/non-solvent fractions proved efficient through laboratory experiments. PetE selected be non-solvent for precipitation pure feedstock assumed LDPE products containing additives such dye. simulation model developed estimated precipitate recovery composition 99% flowrate 1024 tonnes per year. In addition, could approximate rough cost estimate that includes utility cost, installation other factors. Technical challenges were eliminated, several assumptions taken into consideration able process.

The hydro turbine dynamics have a considerable influence on the dynamic stability of power system. In the study of dynamic stability, the system is modeled by the linear differential equations (small signal analysis). Small signal stability of power systems is needed in all conditions and only is dependent on the conditions of power system performance before commotion occurrence. This paper pr...

a simple, rapid and low-cost scanner spectroscopy method for the glucose determination by utilizing glucose oxidase and cdte/tga quantum dots as chromoionophore has been described. the detection was based on the combination of the glucose enzymatic reaction and the quenching effect of h2o2 on the cdte quantum dots (qds) photoluminescence.in this study glucose was determined by utilizing glucose...
Simulation of climate change in Iran during 2071-2100 using PRECIS regional climate modelling system
Parameters such as future precipitation, temperature, snowfall, and runoff were modeled using PRECIS regionalclimate modeling system in Iran with the horizontal resolutions of 0.44×0.44°C in latitude and longitude under SRESA2 and B2 scenarios. The dataset was based on HadAM3p during the periods of 1961-1990 and 2071-2100. Theoverall precipitation error of the model in the period of 1961-1990 w...
