Plant and process for performance of heterogeneously catalyzed gas phase reactions

摘要

The present invention relates to a plant for performance of heterogeneously catalyzed gas phase reactions. The plant entails a reactor, at least one line leading into the reactor for introduction of reactants into the reactor, at least one first feed for providing at least one first reactant A, which leads into the line, at least one second feed for providing at least one second reactant B, which leads into the line, at least one third feed for providing a cycle gas G, which leads into the line, a temperature control unit which is disposed in the line upstream of the reactor and is for controlling the temperature of the first reactant A and/or second reactant B and/or cycle gas G prior to entry into the reactor and at least one outlet for products, by-products and/or unreacted reactants from the gas phase reaction.

主权项

1. A plant comprising
a reactor, at least one line leading into the reactor, configured for introduction of reactants into the reactor, at least one first feed, configured for providing at least one first reactant A, which leads into the line, at least one second feed, configured for providing at least one second reactant B, which leads into the line, at least one third feed, configured for providing a cycle gas G, which leads into the line, a temperature control unit which is disposed in the line upstream of the reactor and is configured for controlling a temperature of the first reactant A or second reactant B or cycle gas G prior to entry into the reactor, wherein the temperature control unit is a heat exchanger operable as a preheater or as a cooler, at least one outlet, configured for products, by-products or unreacted reactants from a gas phase reaction, a fourth feed for feeding of process steam D to the temperature control unit, wherein the fourth feed comprises a valve V1, a fifth feed for feeding of cold condensate K to the temperature control unit, wherein the fifth feed comprises a valve V2, and a second outlet for condensate K or hot condensate HK leading out of the temperature control unit.
