The polyethylene process requires a high-quality product while maintaining high standards of process safety. The highly accurate, reliable measurements provided by Servomex gas analyzers, using cutting-edge sensing technologies, ensure the highest standards of product purity, highly responsive process control, and dependable safety across the production process.
An exceptionally flexible material, polyethylene is widely used in consumer and industrial applications around the world. It is produced by polymerizing the gas ethylene. The ethylene feedstock is treated to remove moisture and other residual gases, and combined with hydrogen and a co-monomer in a reaction system. The quality of these feedstock gases is essential to process efficiency and to protect the expensive catalyst from trace contamination.
The primary contaminants present in the polyethylene production process are oxygen (O2) and carbon dioxide (CO2). It is also important to monitor O2 for safety. Polymerization is a highly exothermic reaction, so it requires continuous cooling to prevent undesirable side-reactions, creating a challenging environment for gas analysis. Additionally, the product stream requires accurate gas analysis – including the measurement of total hydrocarbons – to ensure safety in the headspace by ensuring the concentration stays below its lower explosive limit.
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 for both purity and safety in polyethylene production. Fully certified for continuous measurement of flammable samples, the resilience and flexible measurement architecture of the SpectraExact 2500 helps ensure accurate monitoring of CO2 impurities and total hydrocarbons in the form of n-hexane. It also provides essential ethylene concentration measurements to assure feedstock purity.
For accurate measurements of oxygen contamination in the feedstock, Servomex supplies the SERVOTOUGH Oxy 1900. Designed to operate with accuracy in hazardous conditions, this gas analyzer offers the enhanced reliability of stable, non-depleting Paramagnetic sensor technology. A heated sample compartment provides unrivaled stability and simplified sampling. The Oxy 1900 can also be used to monitor oxygen for safety in the catalyst feed, and in the final product stream.
