摘要： The invention relates to a method for the measurement of the pressure in a gas phase from rectification and/or absorption columns comprising (meth)acrylic acid the esters and/or nitriles thereof by means of open drillings in the column wall and lines from the drillings to the measuring transducer, whereby the lines are flushed with an oxygen-containing gas in the direction of the open drilling.

摘要： Disclosed is a thermal rectification method between at least one gaseous and at least one liquid flow of substance, at least one of which contains (meth)acrylic monomers, in a rectifying column comprising mass transfer bottoms as effectively rectifying built-in units. According to the invention, the liquid flow of substance is polymerization-inhibited and is used for spraying the surface of the rectifying column. Areas of the built-in units, which are located in the shaded zone of the sprayed substance, are led out of the shaded zone by means of a lining process.

摘要： The invention relates to a method for filling a vertical tube having an inner diameter of 50 mm or less with catalyst particles. According to said method, a filling aid comprising a flexible longitudinal body is introduced into the vertical tube, the ratio of the cross-section of the flexible longitudinal body to the cross-section of the tube being between 0.003 and 0.08, and the tube is filled with the catalyst particles.
