Chemicals are often required to ensure the satisfactory operation of crude oil or gas processing plant.

EPD is independent of any chemical supply company and can therefore offer impartial advice on chemical treatment programmes and their selection. EPD can offer a full range of laboratory screening trials and can assist in the field testing of selected chemicals. Furthermore, EPD also offers assistance to clients in the compilation of a toxicological database or risk assessment for all the chemicals used within a production system or at a production plant. The main factors requiring chemical optimisation are:

Process Performance

• Demulsification
• Foaming
• Pour point depression
• Wax inhibition
• Flocculation
• Reverse Demulsification (deoiling)

System Health

• Corrosion Inhibition: Maintenance of surface films to protect vulnerable surfaces
• Bacterial Control: Continuous control of aerobic or anaerobic bacteria combined with regular shock dosing where appropriate
• Scaling Inhibition: Reducing damage caused by uncontrolled scaling of internal surfaces
• Wax inhibition: Preventing the formation of waxes at low operating temperatures
