ISA Analysis Division Symposium 2019

Chemical plants rely on continuous and batch production processes, each posing different requirements for a control system. A continuous process calls for a robust and stable control system that will not fail and cause the shutdown of a production line, whereas the emphasis with a batch process is on having a control system that allows great flexibility in making adjustments to formulas, procedures, and the like. Both kinds of systems need to be managed in available quality history of product, and to be able to execute non-routine operations. With its extensive product portfolio, experienced systems engineers, and global sales and service network, Yokogawa has a solution for every plant process.

The PH450 pH and ORP analyzer is a multivariable analyzer that combines pH with temperature and ORP (Redox) measurement, which can be utilized through different output functions: two mA current outputs, four independent SPDT contact outputs and HART. 

Conductivity meters, analyzers and transmitters are used for continuous process measurement and monitoring of conductivity, resistivity, WIFI, demineralizer water, RO water, percent concentration, boiler blowdown and TDS.

Yokogawa’s new TDLS™8000 houses all of the industry’s leading features in one robust device. The platform design is for in situ measurements which negate the need for sample extraction and conditioning.

pH and ORP meters, analyzers and transmitters are used for continuous process monitoring of pH and ORP to ensure water/product quality, monitor effluent discharge, batch neutralization, pulp stock, scrubbers, cooling towers, chemical, water/wastewater treatment and many other applications.

The PH400G EXA PH intelligent pH analyzer is a highly reliable advanced function pH measurement system designed for wide application in all industries such as for medium-scale waste water treatment system, and general-purpose pH measurement and control systems.

The PH400G features highly effective built-in functions for electrode diagnosis that are similar to those of the EXA PH202 2-wire pH/ORP analyzers. These functions monitor sensor errors even while pH measurements are in progress, enabling more highly reliable pH measurement.

The PH400G also offers an interactive system for setting various parameters, facilitating effective use of its wealth of functions.

The GC8000 has a built-in 12-inch color touchscreen display that dramatically simplifies operations. At the touch of the screen, the technician can access all of the analytical parameters and measurement results; displayed in easy-to-understand graphical color screens.
 

Tunable Diode Laser Spectrometer (TDLS) is a laser-based gas analyzer with fast-update optical analysis.
