Petrochemical Industries

In petrochemicals refinery plants or Gas processing plants, Sulphur is recovered from plants by thermal reactor process and this process is well known as Sulphur Recovery Unit (SRU) or Clause Process. Sulphur is naturally present as an impurity in fossil fuels, Fossil fuels include coal, petroleum, natural gas, oil shale and heavy oils.

Sulphur is extracted at a very high temperature from the SRU reactor; thus, it is very critical to control the temperature to protect the refractory lining & reactor’s viability.

AST has a special solution for Sulphur recovery unit application with a two-channel model for measurement of refractory temperature, gas temperature and smart hybrid temperature. It is a highly accurate digital Fibre Optic industrial IR Pyrometer, for non-contact temperature measurement in demanding applications. Infrared Thermometry Fibre Optic Pyrometers are widely used in high ambient temperature and explosion-proof applications without cooling and in processes involving digital interferences.

Recommended Pyrometer: AST SRU FO PL


Temperature range
350°C to 2000°C
