INTRODUCTION
Within the cold-box of ethylene plants, build-up of NOx (NO and NO2) is a significant safety concern, as it may lead to accumulation of unstable liquid or solid nitrogen oxide deposits. Such unstable deposits have led to several serious explosions and overpressure conditions during shutdowns and cold-section warm-ups.

NOx CHEMISTRY IN THE COLD-BOX
Though NO2 is removed from the gases during the scrubbing process, NO, NH3, and O2 remain in the system. As the temperature decreases and the gas stays in one place for a longer period, NO and O2 are more likely to react, creating NO2 and N2O4. As the temperature decreases further yet in the cold-box, NO and NO2 convert ot N2O3. If NH3 is present, NOx reacts to deposit salts.

Though these accumulations of liquid and solid NOx and salts may cause equipment plugging, frequently there is no external signal alerting operators to the presence of these deposits.

HAZARDOUS CONDITIONS
If the cold-box is allowed to warm (i.e., during system shutdown) while gas is flowing in the system, the deposits begin to decompose into NO and NO2, which will readily react with olefinic material, forming "gums". These gums are explosive at cryogenic temperatures. Thus, since NOx deposits indicate the presence of a strong oxidizing agent within a flammable gas flow, it is clear that any decomposition of these deposits may result in a dangerous, if not life-threatening, explosion.

HAZARD AVOIDANCE
It is clear that build-up of NOx within the cold-box is to be avoided, and detection of the presence of NOx in the process stream is the first-step in creating a safe process environment. C.I. Analytics is committed to being part of this safe workplace.

C.I. AND NOx DETECTION
The C.I. Model 2020PGC Analyzer, equipped with our state-of-the-art Nitrogen Chemiluminescence Detector detects PPT-LEVELS of NOx in the cold-box, creating the "first line of defense" against potentially hazardous conditions!
