Scale Inhibitor Para B9421

Scale inhibitor “B 9421” is a balanced composition of chemical components in a water-alcohol solution, which is based on organic phosphonates. The product is designed to prevent precipitation and deposition of salts on various technological pipelines and apparatuses used in the process of oil and gas production and processing, as well as in water vapor-condensate systems. The inhibitor can be used for corrosion protection of ferrous and non-ferrous metals, both as part of a complex treatment, and separately. 

In accordance with the current technical specifications TU 2482-031-17423242-2009 with amendments 1.2, the scale inhibitor “B 9421” is produced in three grades: A, B, C.

Used in services

Protection of equipment of water circulation systems

Application

In most cases, the B 9421 inhibitor is continuously dosed into the system using a dosing pump. The dosage can be carried out both directly from the drums with the product, and from the working reagent containers. For ease of dosing, “B 9421” can be pre-diluted with water. If the inhibitor is used in conjunction with a biocide, then it is applied after the biocide. 

Dosage

The dosage of inhibitor “B 9421” directly depends on the actual conditions of use and water hardness and can be in the range of 50 – 500 g / t.
