Waste heat recovery has been commonly accepted as an efficient, clean, reliable, and promising approach to increase the utilization efficiency of primary energy and reduce the pollutant emissions. A RNGCS (retrofitted natural gas-based cogeneration system), in which domestic hot water is heated...

A multiperiod mixed-integer linear programming (MILP) model for the operational planning of steam power system (SPS) is presented. The objective of the model is to simultaneously minimize the total economic cost and environmental impact. The environmental impact in the present approach is...

Complex turbines with multiple controlled and/or uncontrolled extractions are popularly used in the processing industry and cogeneration plants to provide steam of different levels, electric power, and driving power. To characterize thermodynamic behavior under varying conditions, nonlinear...

Heat Integration, an effective energy-saving technology, has been popularized in many fields. In the current paper, Pinch-based Heat Integration technology is applied in the Heat Integration of process surplus heat (PSH) and regenerative Rankine cycle (RRC)-based steam power plant. PSH is...

One or more interconnected steam power plants (SPPs) are constructed in a petrochemical complex to supply utility energy to the process. To avoid large economic penalties or process shutdowns, these SPPs should be flexible and reliable enough to meet the process energy requirement under varying...

The sustainable design configuration of utility systems incorporating pollutant emission abatement technologies has an important influence on economic cost, pollutant emission, and energy consumption of the process industry. In this paper, four typical cogeneration systems that address different...
