Energy saving technology of allocation of protein-bearing fractions from oilseeds with use of the paroezhektorny thermal pump

Abstract

The production cycle of complex processing of oilseeds with receiving vegetable oil, soluble and insoluble fraction from mix of the crushed pressing with heated water is offered; a squirrel from soluble fraction, the dried-up insoluble fraction. The main basic decision on decrease in energy consumption was the optimum choice of temperature differences in the evaporator and sections of the two-section condenser when receiving drying agents, the cooling air and warm water. The deviation from these values inevitably leads to increase in the consumed energy: fall of temperature of boiling of coolant in the evaporator on 1 °C results in need of increase in a consumption of working steam in the ejector of the paroezhektorny thermal pump, and therefore to an energy overexpenditure for 5–7 %, and temperature increase of condensation on 1° C leads to increase in power consumption by 2.0–2.5 %. The offered technology expands borders of energy efficient interface of objects of various temperature potentials on the basis of utilization and recovery of secondary energy resources. Universal approach in creation of the competitive technology providing heat generation and cold weather for in common proceeding heattechnological processes is fully realized. Ecologically safe conditions in implementation of technology due to use of water as coolant, excepting use toxic, vzryvo – and fire-dangerous working environments and also at the expense of the organization of the closed recirculation schemes for material and power streams with considerable decrease in removal of secondary energy resources from the scheme warm and cold supply are created.

Exergetic analysis of the production technology of biodiesel from rapeseed oil

“…Эксергетический анализ показал, что эксергетический КПД для технологии получения биодизельного топлива в сверхкритических условиях с применением ПЭХМ составляет 14,39 %, что на 4…5 % выше, чем у известных технологий [1,2]. При переходе технологической системы в состояние равновесия с окружающей средой эта часть энергии (14,39 %) полезным образом использована в термодинамических процессах предлагаемой технологию, что характеризует ее как теплотехнологичскую систему с более высокой степенью термодинамического совершенства, достигнутой за счет организации замкнутых термодинамических циклов и использования отработанных теплоносителей.…”

Reduction in resources consumption when producing agar from the Far-Eastern ahnfeltia

“…Under present-day conditions of reduction in the stocks of primary natural resources, rising consumption and deficiency of energy, the questions of rational use of energy, raw materials and development of the energy-efficient processes and apparates are increasingly more put [1,2,3]. It is particularly true for the energy-intensive technologic processes based on processing the slowly renewable natural plant raw material.…”
