PROBLEMS OF SECONDARY ENERGY RESOURCES SALVAGING AT PETROCHEMICAL INDUSTRY ENTERPRISES

Plotnikov V.V., Petrova O.G.

For petrochemical industry enterprises the main energy resources use efficiency upgrading directions for the moment are: a) the energy resources and secondary energy resources use accounting and control system creation; b) the performance analysis and technology updating; c) the exchange of earlier technologies and equipment for advanced ones; d) the energy saving organization on the basis of energy-engineering combination principles.

At the petrochemical industry enterprises the waste energy use is provided, but the degree of their utilization and directions of use are imperfect for the most part imperfect and require a further elaboration.

From the main waste energy use trends adduced in scientific literature only the following ones can be recommended to the industrial isopropyl benzene production: a) the process stream warming-up in the primary and secondary processes; b) the production area and dwelling heating; c) the source and chemically purified water warming-up; d) the ventilation systems´ air heating; e) the waste vapor compression heat pump system use within the product and semiproduct dispenser and recovery systems; f) the various parameter cold production; g) the water vapor production.

The exergy method of thermodynamic analysis has a good, constantly developed methodical base and is widely used for the analysis and evaluation of the heat and power systems´ thermodynamic perfection.

When developing new energy saving technologies they usually confine themselves to the modernization of separate elements of heat and technology schemes, pay insufficient attention to the creation of integrated systems of heat and refrigeration supply enterprises inclusive of those using low-potential secondary energy resources.

The share of waste energy consumption from the waste treatment facilities is very low nowadays and makes at the average 8-10%. At the high-temperature technology enterprises the share of internal waste sources heat production achieves 50% of the total heat consumption. At the low-temperature processing the utilized heat consumption share makes total only 4-8%.

The work is carried out within the framework of the RF President Fellowship МК-4325.2007.8.
