Abstract:

The project aims to design a carbon dioxide methanizer for low carbon energy systems sustainable development. The experimental model shall be validated through particular testing and validation procedures. Furthermore, innovative integration perspectives will be investigated in order to ensure depolluting of traditional fuel fed plants. Thus, the current proposal falls within the scope of Eco-nano-technologies and advanced materials domain, Decontaminating technologies subdomain. Enabling the power sector transition towards reduced emissions generation is a highly complex matter. In a greater environmentally restricted and increasingly uncertain power generation context, the project addresses the design and validation of methanation tank possibly coupled to a diesel generator, considering a further innovative and integrative approach within hybrid energy systems. Sustainable development is tackled worldwide, regulatory and decision factors leading towards higher levels of energy security and climate change mitigation, mostly through measures comprising RES integration, decarbonization facilities implementation and technology efficiency improvement. Low CO2 emissions power generation scenarios are thoroughly investigated, most of the time comprising decarbonization installations. CO2 utilization, not widely employed currently, reduces the need of its storage (from CCS approach). Therefore, CO2 methanation represents a better alternative to reduce harmful emissions and tackle with multiple safety and economic issues related to the storage section of a CCS installations. Moreover, the project aims an innovative approach in the field of decarbonization technologies, both nationally and worldwide, further research and demonstration being required. The scope of the project follows a multi-perspective sustainable development pathway, its outcomes contributing to improve the actual energy framework.

Abstract:

The proposed research topic is considering the environmental aspects resulting from the leather and fur processing industry. Thus, the project focus is on the treatment and recovery of the resulting products from the processing of hides and pelts, such as: crude fats derived from skin to be extracted, modified, and recovered from its use as biofuel used in the training of an auto engine, either by digestion with sludge from wastewater treatment in a tank for the production of biogas, used as a heat source. The protein also results will be treated and recovered from its use as a fertilizer in agriculture.

Chemical processing of hides and fur is an important source of environmental pollution through wastewater due to the great diversity of chemical products used in fabrication (salts, acids, caustics, dyes, grease products, degreasing, etc.), but due to the removal of the skin, during processing of the organic compounds in an appreciable proportion (from gross skin lies only 60% in the final product). The amount of wastewater from tannery is great, if it is proposed that for getting a ton of finished leather is consumed an average of 70m3 of water. The concentration of production in high-yield tannery involves special problems of environment protection, given that virtually all of the technologies of processing of hides and pelts are sources of pollution. Waste waters have a complex chemical load, made up of proteins and fats from the skin, and the gross excess chemicals used in various phases of processing.

Through multidisciplinary implications of the project, the implementation of the project consortium consists of academic institutions and private companies from different domain activities. In concordance, the project coordinator is University Politehnica of Bucharest, the project implementation team includes teachers, doctoral students and young researchers from Power Engineer Faculty and Mechanical Faculty who will investigate the methods to exploit the useful components of the waste from tanneries in the energy field that make up the project research novelty, also a team with rich experience in the tanneries processes and technologies from the National R&D Institute for Leather will work to find new methods to separate grease and proteins from the crude hide, the economic and social impact of the project results will be analysed by a research team within The Bucharest University of Economic Studies, a research team from the Police Academy "A.I. Cuza", Fire Officers Faculty will identify the risk situations at explosion that may occur in biogas reactor.

The beneficiary of the project results is SC TARO COMIMPEX SRL BUCURESTI, a company with tradition in leather processing. The separation of fats and protein from the waste of skin will be performed using an installation made by SC BERIMEX SRL BUCURESTI. For pipeline networks, the biogas reactor and automation installations the SC ICPE Bistrita will be involve, a company with tradition in the design and implementation of treatment plants and wastewater treatment plants gained through work carried out under the programmes of the national R&D and applications deployed in more than 20 years of activities.

The general objective of the proposed project is the design and implementation of modern waste treatment facilities and the recovery of waste from leather and fur processing industry with the use of components useful novelty in the energetic field. Research results will be through the publications and patents, so it will make a significant contribution to increasing the visibility and impact of the Romanian research to international level.

Abstract:

The project proposes an innovative energy vector and develops theoretical and experimental researches allowing the implementation of feasible and reliable technologies for economical and social use. For the development of the project there is a strong material base, which covers all activities envisaged. Proposed innovative technology for efficient combustion of biomass includes breath of hydrogen produced by hydrolysis of biomass over water particles. This technology aims to increase combustion performance with a very low amount of hydrogen, based on the easy absorption of hydrogen into the existing pore structure of solid biomass. The technology will also highlight the dynamics of sulfur oxides emission reduction that will be further tested in pilot plants. Mathematical modeling of combustion equations will allow for the degree of adsorption to highlight the general effects of combustion, expressed by the speed of ignition, burning rate, emissions. The transition to making experimental combustion will be consistent with data from modeling and numerical simulation. There will be separate tests of the hydrogen adsorption by the biomass, including testing the speed and amount of hydrogen abstraction.

For the innovative point of the research, the study is a new approach of revaluing the renewable energy as biomass potential enhancing with an energy carrier: hydrogen. There are many researches on the combustion of hydrogen with coal, fuel oil,bio fuel, but none with reed.
