ZTW Iron Ion Stabilizer
description1
Product Description
In acidizing, fracturing, and water-injection operations in oilfields, instability of metal ions—especially ferric ions—is a common problem. The iron ion stabilizer (iron chelating agent) has excellent capability to stabilize Fe³⁺ ions and effectively prevents the formation of iron-gel precipitates.
Application Characteristics
ZTW-1 is suitable for environments with temperatures below 90°C.
ZTW-2 is suitable for environments with temperatures above 90°C.
ZTW-3 is suitable for surface crosslinked-acid applications.
Depending on the Fe³⁺ concentration in the medium, the recommended dosage is 0.3%–1.0%
