Pachem-DR3719
Crude Oil Demulsifier
General Information:
Pachem-DR3719 is a unique composition of ionic and nonionic surface active agents. Demulsifier Pachem-DR3719 is used for the breaking up of water-in-oil emulsions. It induces excellent separation in two phases: crude oil and good quality water. It is characterized by good solubility in crude oil and is stable in an applied range of temperatures from -30°C to + 55°C. Pachem-DR3719 does not contain toxic phenolic groups. Additionally, demulsifier contains some components which protect against corrosion.

Application:
Pachem-DR3719 is dosed to wellheads. Pachem-DR3719 :
• it lowers salinity of crude oil
• it separates of emulsion water / crude oil in two phases: hydrocarbons and water
• it lowers viscosity of heavy crude oil. Pachem-DR3719 can be used also in oil demulsification processes in refineries.
Treat rate:
Pachem-DR3719 is dosed into wellbores in the amount of 10 ppm (by weight) and then is directed with crude oil to separation system. In refineries, demulsifier can be injected in the pipelines and by batch in storage tanks.
Packaging:
Pachem-DR3719 is available in 200-litre barrels or 1000-litre tanks. Other types of packaging are available on request.
