摘要: A method for concentrating, in order to favour the subsequent extraction process of intracellular lipids, a cell suspension containing a biomass of oleaginous yeasts fermented in fermentation broth under conditions that allow the intracellular accumulation of lipids, where the biomass contains significant quantities of mucilaginous material. The method includes:a) cultivating the oleaginous yeasts in a fermentation broth to obtain a cell suspension containing the mucilaginous biomass;b) subjecting the cell suspension obtained from a) to heat treatment, at a temperature between 95° C. and 120° C. and to acid treatment, to obtain a treated cell suspension containing the mucilaginous biomass containing intact oleaginous yeast cells; andc) concentrating the treated cell suspension obtained from b), by removing at least part of the fermentation broth to obtain a concentrated cell suspension.

摘要: A method and system are described, for the continuous remote monitoring of deformations in a pipeline (10) suitable for the transportation of a pressurized fluids, such as, for example, pipelines designed for the transportation of low- and high-pressure fluids (natural gas, crude oil, water, oil products) that cannot be controlled by using Intelligent Pipeline Inspection Gauge (PIG) systems, or sections of pipeline exposed to the risk of landslides and/or earthquakes in which catastrophic breakages can be generated, with a consequent interruption in the transportation service. The method and system envisage the application of the guided wave technique for the remote-controlled monitoring of the tensional state of the pipeline (10) also on extensive sections, having a length equal to hundreds of meters, using a relatively reduced number of sensors (12) installed on the outer surface of the pipeline (10).

摘要: Process for the production of lipids from biomass including at least one polysaccharide, which comprises fermentation of a biomass hydrolysate using an oleaginous microorganism and separation of oleaginous cellular biomass comprising lipids. An aqueous fraction obtained by reverse osmosis of a spent fermentation broth is recycled as a feed for growth of the oleaginous microorganism. The lipids thus obtained can be advantageously used in the production of biodiesel or green diesel which can be used as such, or in a mixture with other automotive fuels.

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.
