CHEMICAL PRODUCTION PROCESSES, CHEMICAL PRODUCTION SYSTEMS, AND METHODS FOR MONITORING AND ALTERING REACTOR CONDITIONS.

摘要

The present invention includes chemical production processes and systems as well as methods for monitoring and altering reactor conditions. A method for monitoring reactor conditions includes monitoring reactant recovery stream density and altering the condition when the density reaches a predetermined amount. A chemical production system is provided that includes a reactor unit receiving a reactant recovery stream from a separation unit where the stream can be monitored by a density monitor. A chemical process is also provided that includes reacting a reactant and a starting material in a reactor unit having reactor parameters and producing a product stream that includes the reactant, a product, and a by-product. A recycle stream comprising the reactant and the by-product can be separated from the product stream and returned to the reactor unit. The recycle stream density can be monitored at least periodically and the reactor parameters altered as the density indicates an increased concentration of the by-product in the recycle stream.
