Abstract: In a method and apparatus for cleaning pipe-shaped filter elements arranged in a housing including a separation wall dividing the housing into a clean gas space and a raw gas space into which the filter elements extend from the clean gas space through the separation wall and the raw gas is directed from the raw gas space through the filter elements into the clean gas space while dust is removed from the raw gas and collected on the filter elements, the filter elements are cleaned from time to time by supplying momentarily pressurized flushing gas to the clean air space which, at the same time, is closed to generate a flushing gas pulse providing for a backflow of clean gas from the clean gas space to the raw gas space, which dislodges dust collected on the filter elements.

Abstract: FIELD: industrial organic synthesis. SUBSTANCE: caprolactam is prepared by liquid-phase interaction of 6- aminocapronitrile with water at elevated temperature. Catalyst-free reaction mixture is heated in reactor A to form mixture I consisting largely of water, caprolactam, and high-boiling fraction. Mixture I is converted into mixture II by removing water to leave largely caprolactam and high-boiling fraction. Mixture II is then separated by distillation into indicated constituents. Separated high-boiling fraction is processed according to three versions: fraction is returned into reactor A; fraction is treated in reactor B; or fraction is processed in reactor C under reduced pressure in presence of base. Reaction mixtures from reactors B and C are distilled to give additional amount of caprolactam according to the same scheme, which is used to treat reaction mixture from reactor A. Process in reactor A is carried out at 200-370 C and pressure 0.1 to 50 MPa with excess water 10 to 150 mol per 1 mol of nitrile. EFFECT: simplified technology due to lack of catalyst separation and regeneration stage, and minimized formation of by-products. 6 cl, 4 ex
