Nanomaterials in the chemical industry

Concepts of nanoscience, nanotechnology, and nanomaterials are discussed. Problems that arise during study of the properties of nanostructures are noted. A list of methods is presented for the production of nanomaterials. Basic phases of cryochemical technology in the production of nanodimensional salt powders are indicated. Results are presented for theoretical and experimental investigations of the cryochemical nanotechnology employed for the production of highly disperse KNO₃ powders. __________ Translated from Khimicheskoe i Neftegazovoe Mashinostroenie, No. 7, pp. 14–19, July, 2007.     

Hydrocyclones for the chemical industry and cleaning devices for circulating and waste water

It is pointed out that the operating indicators of a hydrocyclone will depend on its structural and regime operating parameters, while its standard size will be determined by the diameter of its cylindrical section. Both the separation and also the economic indicators will depend on correct selection of the standard size of the hydrocyclone for the specific suspension (emulsion) to be separated. Designs of hydrocyclones are presented in metallic and plastic versions intended for use over a broad range of flow rates and physicochemical properties of the suspensions being separated. __________ Translated from Khimicheskoe i Neftegazovoe Mashinostroenie, No. 7, pp. 20–22, July, 2007.
