Energy utility system mathematic modelling and optimization at the hydrocarbon processing plant

The methods of optimization and mathematic modeling of energy utility systems at hydrocarbon raw materials (natural gas, gas condensate and oil) processing plants have been developed. They are based on calculation modules of separate facilities and units; technological process mathematic models; creation of a rational energy-balance involving gaseous waste, using them in the processes of electricity, heat, cold production. Energy consumption management examples are presented in dependence on the process industry scheme parameters. Technical solutions for design of the energy efficiency fuel utility system are given. The results of the technical, economic and energy efficiency optimization for the structure and parameters of energy resources providing systems are described.
