IP & E APPLICATION
ETHYLENE DICHLORIDE PRODUCTION
The ethylene-based route to PVC production , using ethylene dichloride ( EDC ) as an intermediate , is the predominant method globally . Gas analysis is required at several points throughout EDC production , for process control and quality monitoring . A variety of technologies are required to measure the range of gas components within the process .
Analyzer systems must contend with challenging process conditions , including condensation and corrosion . Large amounts of hydrogen chloride , EDC and residual water can increase the corrosion damage , so a resilient analyzer that can make accurate moisture measurements in the EDC stream is required .
KEY SOLUTIONS
SERVOTOUGH SpectraExact 2500
Our rugged , highly flexible SERVOTOUGH SpectraExact 2500 photometric gas analyzer delivers many of the key measurements required in the EDC process , including residual water levels in the EDC stream . Capable of single and multi-component analysis , it can also be used to monitor ethylene , sodium hydroxide , and hydrogen chloride in the EDC production process .
