Patent ES-8201501-A1 (ES)
Title: Process for producing hydrogen fluoride and phosphoric acid
IPC: C01B7/19
Filed: 1981-01-22
Abstract: An improved method for producing hydrogen fluoride from fluoride bearing ores, such as fluorospar and fluorapatite, by reaction of the ore as a slurry in fluorosulfonic acid. The slurry is heated by the exothermic heat of the reaction to vaporize volatile phosphorous compounds and substantial quantities of hydrogen fluoride. The calcium fluoride is substantially reacted to form hydrogen fluoride. High silica fluorospar ores can be used since silicon tetrafluoride is not formed with fluorosulfonic acid. Another feature provides for addition of calcium fluoride to the slurry to react with the by-product sulfuric acid in the residual solids to eliminate the sulfuric acid recovery step in the process. Hydrogen fluoride produced is recovered, together with the hydrogen fluoride produced from the hydrolysis or pyrolysis of the intermediate fluorophosphorous compounds. Additionally, at least a portion of the hydrogen fluoride can be reacted with sulfur trioxide to form fluorosulfonic acid for makeup in the process.

Patent ES-8300954-A1 (ES)
Title: Rotary compressors.
IPC: F04C29/02
Filed: 1981-04-29
Abstract: A rotary oil mist compressor has a rotor stator unit (10, 12) in which, in use, air is compressed and oil is injected into the air. A primary separation means comprising an impingement shield (24) around the stator separates the majority of the entrained oil droplets from the compressed air. Secondary separation means comprising one or more tubular filters (40) separate substantially the remainder of the entrained oil. The pathway between the primary and secondary separation means includes four substantially right angle bends, two of which are at the entry and exit of a secondary separation manifold (38) in which oil is coalesced by the acceleration and turbulence which occurs at each bend and then returned by the compressor pressure for re-use. The oil separation load on the tubular filters is thus reduced and the oil separation efficiency increased.

Title: Device for picking up a polluting layer from the water surface.
IPC: B63B35/32
Filed: 1984-08-30
Abstract: The device can be used for removing pollution from stretches of the sea. It consists of a hull (12) fitted with means for propulsion and having a central part (10) which bows out towards the front with respect to two lateral sections (11). These lateral sections, together with the central part, define channels leading to the separators. The central part has deflecting elements, such as vanes (17), to create eddies whose orientation tends to reduce the separation of the surface flow around the hull. Each lateral section defines, in a portion located in front of a first capture threshold (18), an open channel letting communication at depth persist. This allows water to flow from one side of the side hull to the other. The front end of each side hull is connected to a blade (14) for connection to the submerged part of the central hull in front of the stem (13) of the side hull. This blade is designed to deflect the flow of the deep layers towards the bottom and towards the outside.
