Совершенствование процесса окончательной дистилляции хлопковой мисцеллы

Аннотация

Objects of research: The cottonseed oil miscelle and free fatty acids, separation process and equipment of free fatty acids during the distillation of cottonseed miscelle. The purpose of work: The improvement on scientific base of separation process of the free fatty acids from composition of the cottonseed miscelle in final step of distillation process and development the offer for the equipment which will be carried out the above mentioned process. Methods of research: The scientific research, system analysis, mathematical and computer modeling, determination parameters required for modeling, undertaking experiment and measurement physico-chemical parameters of the process. The received results and their novelty: Mathematical model of final distillation of the cotton-seed oil miscelle and separation process of free fatty acids from it on rotor disc sprayer and plate apparatus; the use of new methods for expressing the equilibrium conditions the flying components in the countercurrent liquid gas flow; design, calculation and optimized mathematical model of the distillation in opposing flow of the liquid and gas for count created hydrodynamics of the flow structure for count two types design (directing and centrifugal-spraying) of the plates; the achievement in the high mass transfer coefficient because of realization of the process on rotor disc sprayer equipment; the optimum design of the industrial installation of rotor-disc sprayer apparatus for separation easy flying components. The practical value: Creation new intensive resource and energy saving high efficient design device required for fats and oil industry instead of road, not giving expected result, requiring much resources and energy, having greater overall dimentions of device. Degree of embed and economic efficiency: Half industry test of the scientific work is organized in Fat s and Oil plant inTashkent. The Expected cost-performance from introduction offered industrial installation forms 112,7 mln. Sum per year. Field of application: Fats and oil industry.
