On-Line Analyser for Caustic Scrubbers

Caustic scrubbers are key to achieving tight specifications in ethylene and propylene end-products, and necessitate close attention for optimal operation. AppliTek’s field-tested EZ-Caustic on-line analyser system is capable of significantly lowering the process set-point of the scrubber, down to a typical level of 0.5%wt in weak caustic. On-line measurement of sodium hydroxide and other critical alkali parameters is assured, allowing operators to take faster and more decisive actions in the process.

EZ-Caustic automatically samples the outlet and continuously monitors levels of sodium hydroxide (NaOH), sodium carbonate (Na2CO3) and sodium sulphide (Na2S). An ex-proof sampling and preconditioning system specifically built for this application enables automatic outlet sampling, compensating for extreme sample conditions and the presence of polymeric constituents. Furthermore, the simultaneous measurement of all critical parameters allows a superior control of the scrubber’s operation and specific absorption rates, resulting in considerable savings and a fast return on investment.
