Abstract: A method for transporting a viscous fluid through a heat exchanger line that includes transporting a viscous fluid through a connecting piece with an excess pressure release component, where the excess pressure relief component separates an interior of the connecting piece from a discharge line in the connecting piece, and is fixed to an edge of the discharge line, mixing a fluid flow in a region of the excess pressure relief component using a mixing element disposed in the interior of the connecting piece and causing the excess pressure release component to release at least a portion of the fluid through the discharge line when the pressure of the fluid is equal to or greater than a preset excess pressure.

Abstract: A method for producing an amine oxide by oxidation of a tertiary amine in a reactor under continuous introduction of tertiary amine in a reaction fluid and export of amine oxide, wherein a suitable surface-to-volume ratio and/or a suitable flow speed with corresponding surface/volume loads are selected in the continuous process. The reaction fluid is usually reacted in the reactor with a laminar flow.

Abstract: A pipe is provided for transporting a viscous fluid, including a pressure relief valve provided with a sealing element which separates the inside of the pipe from a discharge line and is designed to release the discharge line in the event of predetermined excess pressure. A surface of the sealing element, facing a Miler chamber of the pipe, is associated with the pipe in such a manner that the surface is flown around by a flow of the viscous fluid circulating through the pipe when in operation, and the sealing element is fixed in the closed position by a rod, the rod being displaced by the predetermined excess pressure such that the thus connected sealing element releases the discharge pipe.
