Ethylene dichloride (EDC) is a key intermediate for the production of PVC – we deliver the industry-leading gas analysis solutions you need to overcome process problems including condensation and corrosion.
If you need extra information about our products and application solutions for EDC production and related processes, you can find out more with this selection of downloadable resources.
The ethylene-based route to PVC production, using 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.
The rugged and 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.
With extensive experience in supplying analytical systems for the EDC production process, we provide solutions that are proven to deliver the results you need.
Our experts have deep applications knowledge and can advise on the optimum solution for your plant conditions, supplying gas analysis that exactly matches your requirements.
With a wide range of accurate and reliable gas technologies available, we can deliver the best measurements at every point of the EDC production process.
Our high-performance analyzers are supported by a worldwide network of service staff, ensuring reliable peak performance from day one.
