Detecting sulphides in fluids

Concentration of a sulphide in a fluid is obtained by adding a compound that changes its electronic properties on reaction with the sulphide then measuring the electronic properties of the fluid. Sulphide concentrations in refinery process streams are particularly measured to determine amounts of su...

description Concentration of a sulphide in a fluid is obtained by adding a compound that changes its electronic properties on reaction with the sulphide then measuring the electronic properties of the fluid. Sulphide concentrations in refinery process streams are particularly measured to determine amounts of sulphide scavenger which need to be added. Suitable compounds are exemplified. Claimed per se is a compound obtained be reacting a maleimide and a sulphide.
