TECHNICAL AND OPERATIONAL CHARACTERISTICS OF VACUUM COLUMNS EQUIPPED WITH REGULAR NOZZLES OF DIFFERENT TYPES
This article discusses the results of a survey of seven industrial vacuum columns with different types of regular bits obtained at direct participation authors (three columns with a regular cross-flow nozzle design UNI, one column with a regular design VNIINEFTEMASH counter, two columns with a regular counterflow packing «Gempak «firm» Glitch «, one column with a regular counterflow «Melapak «firm» Sulzer «). According to the results of mathematical modeling of these columns in industrial surveys are technical and operational characteristics of the considered types of regular packing. The first attempt to compare the work of counter-and cross-flow vacuum packed columns reconstructed domestic and foreign firms.
