Sulphur trioxide (SO3) is formed as a by-product during the combustion of fossil fuels for power generation and

is also used or produced in many industrial processes. At temperatures below about 200?C it combines with

water vapor to form sulphuric acid which has deleterious effects on plant surfaces and on the environment.

In power generation SO3 measurements provide data to allow the operator to burn fuel in the most efficient

way to minimize corrosion of the plant and limit acid discharges to the environment.

Monitoring of

SO3 is also important where it is formed as a by-product, e.g. in De- NOx systems.

The Pentol SO3 monitor has been designed to meet a wide range of measuring requirements. The instrument

is portable and suitable for longand shortterm measurements. The unit is auto calibrating in a user

defined cycle. An optional RS232 connector allows to record the measurements on a laptop.
