A complex and challenging process

The synthesis of TDI is both complicated and hazardous. It starts with the nitration of toluene to dinitrotoluene, then the reaction of diaminotoluene and phosgene, proceeding to the distillation of the toluene diamine mixture, and finally the differentiation of the TDI product to produce the required useful isomers. The process combines a range of toxic, flammable, and corrosive components, including hydrogen, chlorine, and carbon monoxide.

An array of impurities to be monitored

The TDI process requires high levels of gas analysis for both process control and product purity throughout all three processes. A wide range of impurities and emissions must be accurately measured, including methane (CH4), oxygen (O2), water (H2O), carbon monoxide (CO), chlorine (Cl2), phosgene, and hydrogen chloride (HCl). This requires a highly flexible analytical solution that delivers safe and reliable measurements throughout the complex production process.

A rugged solution for multiple measurements

A highly flexible, high-performance analytical solution for a wide range of gases, the SERVOTOUGH SpectraExact 2500 uses Infrared and Gas Filter Correlation sensing technologies to deliver the real-time online monitoring needed in the harsh process conditions of TDI production. Fully certified for continuous measurement of flammable samples, the resilience and flexible measurement architecture of the SpectraExact 2500 meets a range of challenges, including overcoming gas cross-sensitivity, and successful detection of chlorine levels in the toxic environment.
