Abstract

The subject at hand is the technology of integrated use of secondary combustible and thermal energy resources of oil refining and petrochemicals for power supply and heat supply of industrial and residential urban areas. Currently, combustible secondary energy resources in petrochemicals in through hydrocarbon gases are burned in smokeless flares and technological candles without practical use in the electric and thermal energy industry. In the production of polyethylene, an average of 230 t/h of spent combustible gases is burned in a smokeless flare at an altitude of 105 m with useless dispersion of the resulting heat in the atmosphere. The heat of heated process water during cooling in cooling towers is uselessly dispersed in the atmosphere or leaves with contaminated spillways and non-return condensate into settling tanks without practical useful application. In the construction of new and the energy supply of existing industrial and residential facilities, there is a problem providing them with electric and thermal energy at low prices. The purpose of this study is to develop a technical solution on the technology of integrated use of secondary combustible and thermal energy resources of oil refining and petrochemicals for the electrical and thermal supply of industrial and residential urban areas.

Highlights

According to the published data for 2019 [1,2,3] in PAO Nizhnekamskneftekhim and PAO Kazanorgsintez, the target of burning waste gases on flares and candles was 5 % of the volume of all gaseous hydrocarbon raw materials used in the technology
In the inter-module cycle of the second embodiment, the primary heating of the water 24 in the absorber 11 is effected by supplying the return water 31 to the heat exchanger 12, from which, at closed gate valves on lines 28 and 29 and open line gate valve, water 31 is supplied by pump 27 for heating to condenser 7 and further in the form of heated water 30 with temperature 70 С at closed line gate valve is directed to consumers
After heating in the furnace heat exchanger 14, the heating water 23 having a temperature of 130 С is supplied to the boiler 3, in which by supplying heat from the combustion products 35, superheated heating water 22 having a temperature of 150 С is obtained

Summary

Introduction

According to the published data for 2019 [1,2,3] in PAO Nizhnekamskneftekhim and PAO Kazanorgsintez, the target of burning waste gases on flares and candles was 5 % of the volume of all gaseous hydrocarbon raw materials used in the technology. 40 ° С in the amount of 30000 m3/h to treatment facilities The absence of using exhaust gases as a fuel for generating heat and electricity is due to their inconstant heat of combustion and their inconstant volumes. In this regard, the study and development of a technology for the integrated sharing of thermal and combustible secondary low-potential resources for electricity and heat for the energy supply of industrial and residential areas are relevant areas in the field of energy [6]. A prerequisite for supplying industrial and residential urban consumers with electric and thermal energy through the use of combustible and thermal secondary resources was to solve the following problems: 1. Collection and analysis of the quantity of secondary combustible and thermal energy resources available at enterprises
