Survey energy efficiency of an industrial system was done. On the base energy audit, the consumption of energy and water was made analyse. On the following audit, there were made choices of energy saving measures, which would lead to proving and economy of energy in the industrial system and condition to work. The ultimate and primary energy savings for the industrial system, as well as CO2 emissions, were determined.
Abstract:The contemporary industry places requirements to them for achieving temperatures lower than -100°C, for example in the liquefaction of gases; liquefaction of air, followed by separation of its components (nitrogen, oxygen, argon, neon, helium, xenon)
The need to provide new sources of energy intensifies research into the use of renewable sources. A good solution is to optimize fermentation methods for bio-waste, which will have a double effect - obtaining green energy and recycling bio-waste that pollutes the environment. This is one of the priorities of the European Union - the new initiative for the circular economy, where recycling of the biomass and receiving pure organic fertilizer is one of the main aims. The report presents a study to determine the working capacity of an available laboratory facility for the production of biogas from biomass through methanogenesis. Experiments carried out have identified some of the design bugs that have been removed. Multiple factors influence this process, and laboratory experiments need to be conducted to determine their impact on the process and on the amount of biogas released to obtain the best result. As a result of four series of experiments, proposals for optimization of the structure and elements of the laboratory establishment and for future research directions were formulated.
Today, more than ever, the fight against climate change requires a collective effort. Addressing the problems arising from the rapid depletion of resources and the changing environment requires Europe to radically change its approach from rapid resource depletion, climate change, and changing environment requires Europe radically change their approach to production, consumption, processing, storage, recycling and disposal of biological resources. The promotion of bioeconomy as a key EU policy will lead to a sustainable solution to these problems and improve the economic and environmental situation in Europe. One of the directions in which the bio-economy has to go at a fast pace is energetics. Using the potential of biomass as a resource for the development of bioenergy will have a positive impact on carbon emissions and climate as a whole. The European Union is pursuing a coherent policy in the field of renewable energy and in particular biomass, stimulating international dialogue to reduce environmental pressures, climate change and reduce the environmental impact of human activity. EU legislation on the promotion of renewable energies (RES) has evolved significantly in recent years, with the agreement reached last year for a 32% share of renewable energy in the overall energy mix at European Union level by 2030. The purpose of this report is to analyze potential opportunities for the implementation of European directives to increase the use of bioenergy resources in the field of energy production. An analysis was made of the state of the Bulgarian energy sector and the current regulatory framework for stimulating the use of renewable energy, in particular biomass for energy production. Conclusions have been formulated for the necessary measures for the future development of the sector.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
