摘要： The invention relates to a method for exchanging heat contained at a fluid. A gas which is heated indirectly and emits infrared radiation is used as the fluid, said fluid being guided to the heat exchanger via an inlet and through art absorber chamber in the heat exchanger, and at least one surface, which absorbs the infrared radiation of the gas in order to use the heat of the gas, is provided in the absorber chamber. The mass flow and the temperature of she gas are additionally adjusted and the at least one surface which is absorbent for the heat exchange is designed such that the ratio dr of the heat flowing through the surface as a result of absorption to the total heat flowing through the surface is ≥0.6 during operation. Thus, a simpler and less expensive heat exchanger can be implemented.

摘要： A safety valve for extraction wells, configured to be installed on a well head and to enclose a tubular material portion inserted inside the well. The tubular material is internally hollow to contain and transport substances extracted from the well. The safety valve includes: a central hole through which the tubular material passes; a blocking system configured to keep the tubular material to be cut fixed with respect to the safety valve; a cutting and closing group configured to cut and close the well under certain operative conditions; and a sealing mechanism configured to effect watertight closing of the well, after the cutting. The cutting and closing group includes a hole saw housed in a respective chamber of the cutting and closing group, rotated by a motorized actuator, and configured to move in a controlled mode along a substantially orthogonal direction with respect to a development direction of the well.

摘要： Process for producing lipids and other organic compounds from biomass comprising the following steps: (a) subjecting said biomass to extraction, at room temperature, in the presence of at least one low-boiling point solvent, thereby obtaining a first organic phase comprising lipids and solvent, and a first slurry phase comprising carbohydrates and proteins; (b) subjecting the first organic phase obtained in said step (a) to evaporation of the solvent, obtaining a second organic phase comprising lipids and a third organic phase comprising solvent, which is recycled to said step (a); (c) subjecting the first slurry phase obtained in said step (a) to liquefaction operating at a temperature ranging from 100° C. to 200° C., preferably ranging from 110° C. to 180° C., at a pressure greater than the water vapor pressure at the temperature at which said liquefaction is carried out, for a time ranging from 30 minutes to 300 minutes, preferably ranging from 50 minutes to 270 minutes, thereby obtaining a second slurry phase comprising sugars, proteins and unconverted carbohydrates; (d) subjecting the second slurry phase obtained in said step (c) to separation, obtaining an aqueous phase comprising sugars and a wet solid phase comprising proteins and unconverted carbohydrates. The lipids thus obtained may be advantageously used in the production of biodiesel or green diesel that may be used, in turn, as such, or in mixtures with other fuels, for automotive transport. The aqueous phase comprising sugars and the wet solid phase comprising proteins and unconverted carbohydrates thus obtained may in turn be exploited.

摘要： Non-aqueous redox flow battery (RFB) comprising: a positive compartment in which a positive electrode is positioned and in which a positive non-aqueous liquid electrolyte is caused to flow; a negative compartment in which a negative electrode is positioned and in which a negative non-aqueous liquid electrolyte is caused to flow; an ion-exchange membrane positioned between the positive compartment and the negative compartment in which: said positive non-aqueous liquid electrolyte comprises a solution of copper triflate or tetrafluoroborate complexes [Cu(I) or Cu(II)] in at least one organic solvent; said negative non-aqueous liquid electrolyte comprises a solution of at least one benzothiadiazole or a derivative thereof in at least one organic solvent. Said non-aqueous redox flow battery (RFB) may advantageously be used in devices which require a moderate to large power output (e.g., about 100 kW-100 MW) for a number of hours (i.e. >1 hour) such as, for example, devices for storing energy derived from industrial plants or from alternative energy sources (such as, solar or wind energy) for subsequent use (for example, for domestic use) or for sale.

摘要： It is described a method for detecting and identifying obstructions in a pipeline network for transporting fluids, wherein the network is composed of a plurality of pipeline sections (P) and a plurality of junctions (N). The method comprising the following phases: acquiring the geometrical data of a predefined number of pipeline sections (P) for which the presence of obstructions has to be evaluated; measuring the actual flow-rate values (Q1) of the fluid in one or more pipeline sections (P) and of the actual pressure values (h1) of the fluid at one or more junctions (N) of the network; comparison between the values of the nominal diameters (D1) of said pipeline sections (P) and the corresponding equivalent diameters (Dieq) of said pipeline sections (P); calculating, by means of a specific numerical model, the theoretic flow-rate values (QiT) and pressure values (hiT) of the fluid for said equivalent diameters (Dieq). With =(Dieq)α×Di method provides a calculation phase of the value of the variables vector αi which minimize a function based on the discrepancy between the actual flow-rate (Qi) and pressure (hi) values effectively measured and the corresponding theoretical flow-rate (QiT) and pressure (hiT) values, wherein said calculation phase is performed by applying a certain own fitness function J(α) of the genetic algorithms (GAs).
