Hydrotemp

Unbeatable experience in refining and petrochemical industries: Sulphur, present in all fuels, converts to sulphur oxides on combustion and on contact with water vapour to acid at lower dew point temperatures. Such acids and their combined chemicals (polythionic acid) migrate through the refractory linings to attack anchor weld points and steel casings, requiring large-scale, expensive repairs to process plant.
