Evaporators used in radiochemical production designed to evaporate highly active solutions and devices designed to create thin film in the heating chambers.

The film former contains a liner in the upper part of the heat exchange tube attached to the spindle of the bellows assembly of the evaporator lid. The liner is provided with a radiation-proof tip that is not wettable by liquid being evaporated. The tip is made of two conjugate cones: the upper back cone and lower right cone, with the lower cone having a cylindrical belt with protrusions on it designed to center the conical tip on the inner surface of the heat exchange tube. A cap is mounted movably on the liner, with grooves on the lower end of the cap along the entire perimeter.

The liner attached to the spindle is connected by fins with adjacent liners installed in heat exchange tubes.

A fluid vapor distillation apparatus. The apparatus includes a source fluid input, and an evaporator condenser apparatus. The evaporator condenser apparatus includes a substantially cylindrical housing and a plurality of tubes in the housing. The source fluid input is fluidly connected to the evaporator condenser and the evaporator condenser transforms source fluid into steam and transforms compressed steam into product fluid. Also included in the fluid vapor distillation apparatus is a heat exchanger fluidly connected to the source fluid input and a product fluid output. The heat exchanger includes an outer tube and at least one inner tube. Also included in the fluid vapor distillation apparatus is a regenerative blower fluidly connected to the evaporator condenser. The regenerative blower compresses steam, and the compressed steam flows to the evaporative condenser where compressed steam is transformed into product fluid. The fluid vapor distillation apparatus also includes a control system.

A distribution chamber suitable for distributing a liquid stream to a plurality of pipe openings distributed over a planar surface. The distribution chamber includes three perforated plates. A method to distribute a liquid stream to a plurality of pipe openings, a method to decompose ammonium carbamate from an aqueous solution comprising ammonium carbamate and a method to produce a concentrated aqueous urea solution from a diluted aqueous urea solution.

The present invention relates to a method of manufacturing spray-dried powders. During the process, a solvent is used. The process is done in multiple steps such that the emulsification mass ratio is low when removal of the solvent is started. Preferred solvents are isopropyl acetate and ethyl acetate. The invention also relates to a set-up to run the inventive process at industrial scale.

A method for cleaning a vaporizer that vaporizes, at normal temperature and pressure, a source material in a liquid state, and supplies the vaporized source material to a reactor through a supply pipe, includes a cleaning step of passing the source material to the vaporizer while maintaining the source material in a liquid state to clean the vaporizer.
