Energy efficiency projects deployment for Ukraine is one of the challenging task today. Ukrainian in­dustry faces very complex environment for project development as well as its deployment within organization nowadays. UA Policy struggle to keep place on the European market to have possibility not only be a part of global policy but to go forward and to bring benefits for macro and micro economy. Fresh breath by integration energy systems within project management into business model of organization let to move closer to hold under control energy efficiency projects realization and avoid financial risks. Environmental policy and energy policy play crucial role for Ukrainian transformation into European pla­yer. Presented proactive plan provides possibilities to deliver the intended economic and environmental benefits of the Ukrainian energy labelling and ecological design directives. These directives are in use or are under development process by increasing the rates of compliance with their energy efficiency requirements. To start from the energy efficiency development process investigation in order to have possibilities to make corrections on the stage of modeling and design can bring benefits and reduce costs for end users. To evaluate the efficiency of heat exchangers, there are over 40 different private integral energy efficiency criteria. Such a number makes the estimation of heat exchangers not always objective and sufficiently definite, which does not allow to algorithmize the task of determining the efficiency of heat exchangers. On the foundation of the system element representation for the heat exchange network, the concepts of energy potential and energy efficiency of energy exchange are proposed. The obtained equations allow us to determine the efficiency of energy exchange not only for an element of the heat exchange network, but also for a complex system as a whole with a minimum of information about the system

Kinematic viscosities of acetone, vinyl acetate, crotonaldehyde, acetic acid, acetic anhydride, their binary mixtures and two ternary mixtures (acetone-vinyl acetate-acetic acid and vinyl acetate-acetic acid-acetic anhydride) were measured. The values of coefficients of the Linke, McAllister, and Chandramouli-Laddha equations were calculated. The temperature dependence of the coefficients of last two equations can be expressed in terms of a function in exponential form, coefficients of which are tabulated.

This paper takes the conversion system of sulphuric acid plant made with the sulphur as research object, utilizes Aspen Energy Analyzer software and pinch technology to improve and optimize for the current heat exchange network of conversion system. The heat exchange network optimized by Aspen software is under the premise of reaching the requirement of heat exchange, its heat transfer area, utilities and operating cost reaches the minimum, achieving energy saving, and it provides a new approach for the optimal design of heat exchange network.
