BACKGROUND Biomass and municipal solid waste offer sustainable sources of energy; for example to meet heat and electricity demand in the form of combined cooling, heat and power. Combustion of biomass has a lesser impact than solid fossil fuels (e.g. coal) upon gas pollutant emissions, whilst energy recovery from municipal solid waste is a beneficial component of an integrated, sustainable wast...

Now a days, In most of the thermal power plant, where low-pressure steam is being exhausted to the atmosphere as a waste steam. This waste heat could be use to operate many small preheating or cooling equipments or small scale plants. There are many refrigeration systems present for refrigeration and air condition purpose. Such as air refrigeration, vapour compression, vapour absorption etc. In...

Waste management has become a great social concern for modern societies. Landfill emissions have been identified among the major contributors of global warming and climate changes with significant impact in national economies. The energy industry constitutes an additional greenhouse gas emitter, while at the same time it is characterized by significant costs and uncertain fuel prices. The above...

We describe a computer algorithm designed to calculate the optimal energy extraction in the form of heat used for steam raising from chemical processes. The concepts are illustrated using chemical plant stream data in a process with multiple distillation columns. Pinch analysis is first applied to find the grand composite curve (GCC) of the problem, which is then used by the algorithm to determ...

Abstract— The effect of calcination temperature on the morphology of plating sludge generated from waste water treatment plant was studied. This waste was hazardous waste due to high toxic metal content [1]. It must be recovered, reuse or recycled before the process but its properties should determined in order to decide recovery method [2]. Previous researches were shown that this kind of wast...

A significant amount of heat is wasted in manufacturing process, electricity generation, chemical and industrial process. Recovery and reuse of this energy through storage can be useful in conservation of energy. In the present study, a double pipe type heat exchanger has been designed and fabricated for low temperature industrial waste heat recovery using phase change material (PCM) paraffin w...

The Cu-Cl thermochemical cycle for hydrogen production was selected on the basis of its high efficiency and moderate temperature requirements. The modeling and simulation of Cu-Cl thermochemical cycle for hydrogen production is investigated in Aspen Plus. Since this cycle is a high energy-consuming process, the heat integration technique is implemented to recover the waste heat such that the pr...
