Solvay – Environmental Monitoring System

Solvay Logo

Irish Power and Process Ltd successfully installed and commissioned an environmental monitoring system (EMS), together with associated field and analytical instrumentation at Solvay in Carrigtwohill Cork.

Utilising Yokogawa’s DxAdvanced paperless and Network based recording system, the system logs data, saves it daily to a secure server, publishes the data on web based reports, and can email periodic data from the field instrumentation or view on demand.
The system also has email on Alarm capability which alerts engineers if the system is moving outside allowable limits, set through its EPA licence arrangements.

DAQSTATION Models display measurement data in real-time on a high resolution TFT color liquid crystal display. Data can be saved to Internal Large ( up to 200MB ) capacity non volatile memory, external CompactFlash memory card, or USB drives , offering an incredible level of security to data storage.. DXadvanced include a standard Ethernet port with built-in Web Server and E-mail functions and TCP I/P and FTP protocol support.

The associated Yokogawa field instruments include Yokogawa Advanced pH analysers pH450, and Yokogawa Magnetic flowmeters Admag AXF.

The PH450 is a touch screen pH transmitter with powerful self diagnostic features that ensure, the pH system is intact, the sensors are immersed in liquid, the system is not contaminated and the glass is not broken. The Model PH450 provides the best pH measurement accuracy in the industry resulting from advanced temperature compensation functionality, preloaded calibration standards, stability checks and online sensor and analyzer diagnostics to provide verifiable results.

The AXF magnetic flowmeter is a product with outstanding reliability and ease of operation, developed on the basis of decades of fieldproven experience.
The AXF magnetic flowmeter is significantly easier to maintain thanks to the combination of replaceable electrodes and a diagnostic function that detects the adhesion level on the electrodes. The AXF also employs a dual frequency excitation method that eliminates fluid noise.

The AXF Flowmeter offers mA output for Flow rate, takes advantage of the flow totaliser functions of the DXadvnaced recorder so separate Flow Totaliser is not required, and offers a pulse output to a refrigerated water sampling system so that samples are taken for lab analysis automatically.

Solvay , who were already familiar with Yokogawa recorder systems on 21cfrPart11 GMP applications are delighted with the ease at which they can view the data from the system and compile it in a way which suits internal and external regulatory personnel .
