New video shows solutions for PTA production process

Our latest application video explains how our accurate, reliable gas analysis solutions help overcome the challenges faced by manufacturers of purified terephthalic acid (PTA).

Together with ethylene, PTA is used to produce the high-demand plastic polyethylene terephthalate, which is also known as PET. PET is widely used as a polyester fiber, and for food and drink containers such as plastic bottles.

The production process for PTA needs gas analysis measurements to ensure process control, efficiency, safety, quality monitoring, and environmental compliance.

Our key solutions include the SERVOTOUGH Oxy 1900 and SERVOTOUGH OxyExact 2200 Paramagnetic oxygen (O2) analyzers, which provide measurements for process control and safety.

These may be used in a three-analyzer voting system to ensure reactor safety, and can also be used to measure residual O2 at the crystallizer stage, and to check for O2 impurities in the nitrogen inert blanket in the PTA product driers and storage bins.

Our SERVOTOUGH SpectraExact 2500 Infrared analyzer provides carbon dioxide (CO2) and carbon monoxide measurements in the off-gas, and monitors CO2 to check for any post-oxidation reaction. It can also be used to measure water in liquid acetic acid, helping to control the recovery and purification of the solvent before it is recycled back into the process.

PTA plants may also use auxiliary boilers for heating parts of the process. The SERVOTOUGH FluegasExact 2700 analyzer is used to monitor the combustion reaction in these boilers.
