In an alkylation unit the acid settler is fed from the reactor vessel which is used to remove acid for recycling back into the reactor. The layers created in the separation process form interfaces that must be tracked to manage the output of the material from the unit. Reporting density on a horizontal plane enables accurate control of the process and maximizes throughput, therefore controlling the acid levels for optimal processing.

Your benefit

Measurement across the span of the vessel with multiple sensors increases the availability
Cost effective
Air/water calibration reduces commissioning time
User friendly
Non-invasive measurement ensures easy and safe maintenance
