Abstract:
The article deals with the determining value of the steady heating of the air line under load. The authors proposed to determine the value of the steady-heating based on real experimental data. To obtain the equation of the heating process were built and analyzed according to steady heating of each environment parameter. Besides that, an algorithm which described steps to creation characteristic curve the steady heating by external factors. The reliability analyze of obtained results, which made by the Fisher test, showed that the proposed model is adequate (F less Fkr more than 4 times). The introduced approach can be used to develop steady state heat conductors models with a sufficiently high accuracy by a low cost of time to collect the necessary data.

Abstract:
Energy conservation in the design of a chemical plant is one of the most important considerations. In addition, to determine the minimum amount of hot and cold energy needed for a process is one of the main computations of determining the amount of stored energy. The heat integration (energy integrating) is an important factor in economic designs. In this paper, phases 9 and 10 of the gas condensate stabilization process of the South Pars gas are optimized using the integration design method. The results obtained showed the modified heat exchanger network, removal of existing both air fans, recovery of 2.5 MW of electricity and reduced operating costs.
