Sulphur recovery analysers

December 2008 Analytical Instrumentation & Environmental Monitoring

UV diode-array fibre-optics technology.

Abstract

Legislation enforcing emission control of toxic substances has now been passed worldwide. An important subgroup of such substances is comprised of the sulphur-based compounds; sulphur recovery units are a critical component of the processes of oil refining and liquefying natural gas. Fast, accurate, and continuous analytical techniques are necessary to comply with these regulations and to improve efficiency in sulphur recovery processes.

A variety of recovery processes are normally operated at a single plant; using a single type of analyser for a majority of applications guarantees better technical support and a higher level of expertise in plant operators.

This paper reviews the utilisation of spectroscopy in step with diode array technology, a time-tested, industry-accepted technology for sulphur recovery applications.

One analyser with different sampling systems can be used for a variety of applications. Common applications include: tail gas, natural gas and mercaptans.

Keeping an eye on invisible radiation
Omniflex Remote Monitoring Specialists Analytical Instrumentation & Environmental Monitoring
At its peak in 1994, the energy generation capacity of the UK’s nuclear power stations was 12,7 GW across 16 plants. In 2024, the capacity has fallen to around 5 GW, and the number of stations is down to nine. However, this is far from the end of the story as spent nuclear fuel remains radioactive for centuries, and requires rigorous safety processes to safeguard against leaks.
