Abstract: The valve is formed in a valve body housing a first path portion, a second path portion, and an coupling zone between the first and second path portions. A shutter is arranged in the coupling zone and has a shutting portion of ferromagnetic material that is deformable under the action of an external magnetic field between an undeformed position, wherein the shutter closes the coupling zone, and a deformed position, wherein the shutter at least partially frees the coupling zone. The shutting portion of the shutter is formed by a rubber membrane incorporating particles, for example of ferrite particles.

Abstract: A sample treatment and molecule analysis cartridge is configured to be mounted in a treatment machine vertically. The cartridge has a sample inlet opening, a fluidic inlet, and a fluidic outlet. The cartridge houses an extraction chamber extending vertically from the sample inlet opening and connected to the fluidic inlet; a waste chamber extending vertically, alongside the extraction chamber; and a collector extending along the extraction chamber and the waste chamber and having a smaller height than the extraction chamber and the waste chamber. A fluidic circuit connects together the extraction chamber, the waste chamber, the collector, the fluidic inlet, and the fluidic outlet, and is configured to connect the fluidic outlet to vent openings of the extraction chamber, the waste chamber, and the collector, and to connect the bottom end of the extraction chamber to the fluidic inlet, the waste chamber, and the collector.

Abstract: A plant for recovering metals and/or metal oxides from industrial process waste, in particular oil product refining waste, comprises a furnace; a feed line connected to a main inlet of the furnace and configured to feed the furnace with a solid waste containing metals, in particular in oxide form; an outlet line, connected to a solid phase outlet of the furnace and configured to draw a metal-enriched solid phase out of the furnace; the furnace is a belt conveyor furnace having a belt conveyor closed in a loop with a substantially horizontal configuration and having a top face, which receives the waste to treat and conveys it between two longitudinal opposite ends of the belt conveyor furnace respectively provided with the main inlet and the solid phase outlet.

Abstract: A counter-current cross-flow heat exchanger for heating a first gas and cooling a second gas, includes modules in fluid communication with one another, each module being positioned on a plane, the planes mutually overlapping. Conduits allow entry and exit of the first and second gases into and out of the exchanger. Each module has heat exchange plates, with heating and cooling faces. The plates are orthogonal to the module plane and parallel to define alternating heating and cooling spaces. The first gas crosses each heating space with a direction substantially parallel to the plane of each module and the second gas crosses each cooling space with a direction substantially orthogonal to the plane of each module. The cooling spaces between adjacent modules are in direct fluid communication. The heating spaces between adjacent modules are in fluid communication with one another by conduits/conveyors, creating a serpentine path.

Abstract: An integrated process for production of urea and urea-ammonium sulphate (“UAS”) comprises: a urea synthesis step carried out in a urea synthesis reactor; a recovery and concentration step, wherein a urea solution produced in the urea synthesis step is progressively concentrated in at least one recovery section and in a concentration section, recovering unreacted ammonia and carbon dioxide and water from said urea solution; a step of producing ammonium sulphate by reaction of sulphuric acid and ammonia in an ammonium sulphate production apparatus; a step of mixing said ammonium sulphate with concentrated urea coming from the concentration section to produce a UAS mixture; in the ammonium sulphate production step, at least a part of the ammonia is provided by at least one off-gas containing ammonia and recovered from the recovery and concentration step.
