System and method for recovery of liquid or free-flowing chemicals

摘要

The present invention describes a system (1) for recovering liquid or free-flowing chemicals in a chemical plant (3), comprising
at least two plant sections (3a, 3b),for each plant section (3a, 3b) at least one connecting device (5a, 5b) arranged at the lowest point,at least one common collecting line (7) which runs beneath the connecting devices (5a, 5b) and connects them to one another,at least one collecting vessel (9) arranged at the same height as or higher than the at least two plant sections (3a, 3b) and above the collecting line (7),at least one pump (11) provided in the collecting line (7) between the connecting devices (5a, 5b) and the collecting vessel (9) for drawing off the at least one liquid or free-flowing chemical combined in the collecting line (7) and introducing it into the collecting vessel (9).

主权项

1. A system for recovering liquid or free-flowing chemicals in a chemical plant, the system comprising:
at least two plant sections of the plant, wherein the at least two plant sections are at least two reactors run in parallel or constitute different stages of a chemical preparation process; for each plant section at least one connecting device arranged at a lowest point in each plant section; at least one common collecting line which runs beneath the connecting devices and connects them together; at least one collecting vessel arranged at the same height as or higher than the at least two plant sections and above the collecting line; and at least one pump provided in the collecting line between the connecting devices and the collecting vessel for drawing off at least one liquid or free-flowing chemical combined in the collecting line and introducing the at least one liquid or free-flowing chemical into the collecting vessel.
