The description of technological process of production of cans of low pressure polyethylene. The results of studies on the estimation of the input technological parameters on the output parameters and characteristics of the product. The mathematical model of the technological process of obtaining products of high density polyethylene. The solution of problems of chemical-technological processes using the method of mathematical modeling, based on the strategy of system analysis. When conducting chemical-technological processes often important to know degree ᅟ completeness their completion , which in its turn, depends on distribution on time stay particle flow in ᅜ apparatus as some share flow can linger in machine and while others slip that directly associated withᅜ time contact and diffusion.
