A distillation column with external circulation evaporator and a sedimentation zone in the bottom of the column, from which the evaporator circulation is fed, and use of the distillation column for the distillation of acrylic acid.

Distillation column and method for distilling acrylic acid

A gas scrubber, equipped with heat exchanger surfaces constructed of thermoplates, suitable for cooling and cleaning a hot gas by avoiding an excessive thermal load of the washing liquid.

Gas scrubber having an integrated heat exchanger

A process for the continuous production of melamine from urea by means of a fluidized-bed reactor, wherein process gas guided in the process circuit is used as fluidizing gas and wherein the temperature of the process gas at the inlet of the conveying means for the fluidizing gas is adjusted by adjusting the mixing ratio of a process gas stream guided over a scrubber and of a process gas stream guided past the scrubber.
