Protection of process and pipeline equipment
Application
Scale inhibitor “PARA IS 2142” is designed to control scale in wells and to protect ground equipment in the field. Its typical application is oil treatment plants. In systems of this kind, as well as in waterflooding systems, the reagent is supplied continuously. It can be pumped periodically into the annulus of producing wells.
Dosage
The dosage of the scale inhibitor “PARA IS 2142” depends primarily on the content of calcium salts. The dosage range can be defined as 5-50 ppm based on the volume of water produced. The volume of periodic injections of the reagent into the wells is determined directly on site, however, in general, this method is less economical than continuous injection.
