Reaction zone monitoring system for the STRATCO® CONTACTOR™ reactor

The RZMS for the DuPont™ STRATCO® Contactor™ reactor allows operators to measure sulfuric acid to hydrocarbon ratio and sulfuric acid strength in the Contactor™ reactor more effectively than a typical ratio glass and acid sampling system assembly. The DuPont RZMS combines the features of an easy-to-read ratio glass, robust acid sampling system, refractometer, Coriolis meter, specially engineered piping, along with the DuPont expert knowledge of Contactor™ reactor operation to provide the customer with an effective tool to monitor the Contactor™ reactor performance. Too often, ratio glass assemblies function poorly, are difficult to use, are poorly maintained, or are removed from service.

Without this important information, alkylation unit operators must rely on secondary or delayed data (sometimes up to 4+ hours) to verify conditions in the reaction zone. Acid sample data is often available in other parts of the unit, but may not represent current operating conditions. Many times when problems develop, the lack of real-time information (acid strength in the reactor, accurate acid/hydrocarbon ratios, etc.) can lead to decisions that exacerbate the problem rather than correct it. The consequences of these decisions will not only impact the unit economics, but may also create an unsafe work environment.

The RZMS unit will give you more confidence in operating the alkylation unit especially at lower acid strengths and will help to avoid acid run-away.
