Steam is a key energy vector for industrial sites, most commonly used for process heating and cooling, cogeneration of heat and mechanical power as a motive fluid or for stripping. Steam networks are used to carry steam from producers to consumers and between pressure levels through letdowns and steam turbines. The steam producers (boilers, heat and power cogeneration units, heat exchangers, ch...

Several decarbonised polygeneration systems exploiting carbon capture and storage (CCS) or CO2 reuse technologies for the conversion of primary resources into clean fuels, chemicals, electricity and heat are systematically analysed for techno-economic feasibility. A process simulation, energy integration and economic analysis based approach has been employed to arrive at a representative set of...

Abstract The district heating systems supply heat to a wide range of consumers. In the source such systems, highly efficient technologies are used for combined production electrical and thermal energy mainly based on steam turbine installations with backpressure turbines or adjustable extractions. Combined leads reduction in fuel consumption (fuel saving) compared separate two products. saving ...

Abstract Circular economy and industrial symbiosis represent a production consumption model involving sharing, lending, reusing, recycling existing materials products in the most efficient way to increase sustainability reduce or eliminate waste. Beef has high impact on environment different categories, especially those activities related livestock breeding feeding. In this study, life cycle as...

Increasing global demand for fresh water is driving the development and implementation of a wide variety of seawater desalination technologies driven by different combinations of heat, work, and chemical energy. This paper develops a consistent basis for comparing the energy consumption of such technologies using Second Law efficiency. The Second Law efficiency for a chemical separation process...

in this paper, the effects of input temperature and compression ratio on the net output work and efficiency of the air standard cycles, i.e. atkinson cycle, diesel cycle and otto cycle are analyzed. we assumed that the compression and power processes are adiabatic and reversible and any convective, conductive and radiative heat transfer to cylinder wall during the heat rejection process may be ...
