Crude Unit Corrosion Control

Condensing corrosive gaseous species like HCl, H2S and H2CO3 create a highly corrosive low pH environment in the crude unit overhead system. TDC‘s dual chemical program consisting of neutralizer and filming corrosion inhibitor, injected into the overhead system and reflux line ensure superior corrosion control and reliability of the equipment.

Crude Unit Preheat & Furnace Fouling

Crude preheat exchanger train and furnace fouling can significantly reduce unit throughput and increase processing costs. Foulant precursors range from scale solids to asphaltene deposition and oxidative polymerization. TDC‘s effective fouling control programs injected into desalted crude provide longer unit run lengths. Improved levels of heat transfer lead to increased profits through higher feed rates and lower fuel costs.

Vacuum Unit Corrosion Control

Low pH due to acid gas condensation in vacuum overhead system results in severe corrosion. An effective neutralizing amine provides good pH control, thus effectively reducing corrosion rates, resulting in less downtime, maintenance, and operational problems.
