Energy & Waste posted this:Biolimp-MPdry. Technology for biogas cleaningBiogas is a dirty gas. Therefore, it requires a previous cleaning to be used as biofuel. There are many components to be removing, among them, water vapor, siloxane, halogenated hydrocarbons and H2S, all of them, affects the good performance of the CHP system. The Biolimp-MPdry technology is a multipropose technology that allows the biogas cleaning with a very lower costs and high performace yield.
Energy & Waste posted this:Biogas dryer. For biogas water vapor removingBiolimp-Dry technology combines the cooling and condensation techniques, allowing to achieve elimination efficiency of over 95% depending on the working temperature with low operating costs. This can include a washer-recuperator, which in addition to minimizing the energy needs of the operation, allows to wash the biogas with its own condensates, which produces a partial reduction of the H2S and NH3, that accompany the biogas, reason why it can be considered a multipurpose technology.

University of Huelva posted this:New method for manufacturing magnetic cores by powder metallurgyMagnetic cores in amorphous state are usually produced by placing together very thin amorphous ribbons from a material obtained by the melt-spinning technique. The new patented method produces the amorphous material by mechanical alloying, a traditional process in the powder metallurgy field. This technique allows a higher control on the amorphisation process and the properties of the amorphous obtained powders. These powders are then consolidated by the very quick process known as Electrical Resistance Sintering (also Electrical Discharge Consolidation/Sintering can be used). A final amorphous material, without the typical frontier between ribbons of melt spinned materials, which clearly affect properties, is obtained.

Furthermore, old buildings frequently suffer from damp and condensation problems. FRIDS is an indoor insulation system that guarantees heat insulation and moist removal sustainable solution for ground-contact wall fragments, fire walls, reveals, etc. and offers a permanent solution to this problems.
University of Huelva posted this:Measurement system for the identification and accurate determination of distorting loads in electrical networks and microgridsThe only measurement of distortion level in a network can highlight the need for action to control it. Among those actions is, for example, the use of power filters. However, the determination of the most suitable point where the filter must be connected and its most appropriate configuration requires further analysis of the micro-network (a subset of nodes in the network with different loads connected to each). Therefore, an additional study becomes necessary to establish the responsibility of each load in global distortion levels. In addition, the establishment of the model of the most responsible loads is also necessary in order to decide the filter configuration. In this sense, the load may be voltage distorting or current distorting. All this information is provided by the device of the invention. Indeed, the device, besides distributing the responsibility for overall levels of distortion between each agent, reports whether loads are voltage harmonics or current harmonic sources. This information is the most relevant to determining the power filter settings that best mitigate the distortion in each network node.
