The invention relates to a method for determining the state of a heat exchanger device () that comprises means for transferring heat with the aid of at least one process stream. A thermohydraulic simulation of the at least one process stream through at least one passage () in the heat exchanger device () is carried out in order to determine temperature and/or heat transfer coefficient profiles of the means for transferring heat.

Method for determining a state of a heat exchanger device

A method for controlling a coupled heat exchanger system having a first heat exchanger block and a second heat exchanger block. A first fluid stream is divided into a first partial current and a second partial current both flowing through the heat exchanger system. A second fluid stream flows through the first heat exchanger block counter to the first partial current. A third fluid stream flows through the second heat exchanger block counter to the second partial current. An intermediate temperature is measured on one of the heat exchanger blocks. The amount of the first partial current and the second partial current is controlled based on the current value of the intermediate temperature. This control reduces the strain on the heat exchangers by changing loads while keeping fluctuations of the intermediate temperature low.

The invention relates to a distribution system () for distributing a fluid () into a container () from a fluid inlet () of the container (). Distribution system () comprises one or more guide plates that form a guide section () and a distribution section () that adjoins the guide section (). Distribution section () has regions () with openings () for allowing fluid () to pass through. The invention also relates to a heat exchanger device () that has a container () with a fluid inlet (), with at least one heat exchanger block () that is arranged in the container (). A distribution system () according to the invention is arranged in the container () above the heat exchanger block ().

Distribution system and heat exchanger apparatus

A reflux condenser and a method for conducting away liquid from the lower region of reflux passages, is disclosed. The reflux condenser has at least one heat exchanger block which has reflux passages and refrigerant passages, and a pressure container which encloses the heat exchanger block at the top and laterally. The reflux passages communicate at their lower end with a header which is arranged below the heat exchanger block and has a phase-separating device.

Reflux condenser apparatus and method

Implementing at least one endothermic and/or exothermic reaction in a compact reactor which has passages for conducting gaseous and/or liquid media, through which passages the reactants of the endothermic or exothermic reaction as well as a heating medium or coolant are sent, whereby The heat exchange between the media mentioned in a) to c) is carried out indirectly and via a third gaseous and/or liquid medium (moderation medium).

Process and reactor for implementing exothermic and endothermic reactions

A plate heat exchanger includes a heat exchanger block having a plurality of heat exchange passages. On the heat exchanger block, a header is mounted that extends over at least one part of one side of the heat exchanger block and establishes a flow connection between the heat exchange passages. The plate heat exchanger is provided with a fluid connection, which is formed by the header-side end of a pipeline. The fluid connection is essentially perpendicular to the side of the heat exchanger block over which the header extends. Within the pipeline directly in front of the header, there is a flow guide.
