Product features
ZX-D3-03 Anionic Flocculant is a high molecular weight, slightly crosslinked, acrylic polymer emulsion containing acid functional groups. Neutralization with bases converts ZX-D3-03 Anionic Flocculant to viscous solutions of highly swollen polyelectrolytes useful for flocculating suspended oil particles in oilfield treatment aqueous media. Salts of ZX-D3-03 Anionic Flocculant increase the settling rate of suspended solids and condition the particle for separation by filtration, centrifugation, sedimentation or flotation.
ZX-D3-03 Anionic Flocculant is used conveniently, because its low viscosity eliminates the handling difficulties often accociated with solutions of high molecular weight polyelectrolyte. To prepare ZX-D3-03 Anionic Flocculant for use, a solution (10% solids content) of a base is added to the diluted emulsion (2% solids content) immediately before treating the suspension.
Applications
ZX-D3-03 Anionic Flocculant is a very effective flocculating agent and can further increase the floc size of previously flocculated suspensions. A greater floc promotes faster settling and improves the filtration rate.
Suspended materials may carry a positive electric charge and, therefore, will not interact with inorganic flocculant such as alum, ferric chloride, or with catonic polyelectrolytes. These agents, therefore, cannot produce flocculation of the systems. Examples of such difficult substances are certain suspended organic or inorganic materials from industrial processes, produced and injected waters in oilfilelds, and commercial or industrial waste streams. Such systems can often be treated successfully with ZX-D3-01 Anionic Flocculant anionic polyelectrolyte.
Other suspensions are best handled by adding ZX-D3-03 Anionic Flocculant and a cationic flocculant. In all cases, jar test should be run to establish the most suitable agents and the optimum dosage levels.
Method of use
The exact method of use is dependant on the unique challenges presented by the specific application. ZX-D3-01 Anionic Flocculant can be diluted as the emulsion and then added directly to alkaline systems to begin flocculation. For lower pH systems, this product may provide optimal performance if first prepared as 1% water soluble salt solutions.

Solubility
Freeze Thaw
Samples of the emulsion product were stored at -3℃ and -18℃ for 16 hours (samples froze solid). After four freeze-thaw cycles, ZX-D3-01 Anionic Flocculant flocculant exhibited very good stability. No coagulum or gelling occurred.
Thermal Stability
Samples of the emulsion product were stored at 50℃ and 60℃. After one week at 50℃, ZX-D3-01 Anionic Flocculant exhibited good stability. However, the product totally gelled between 1-2 days at 60℃.
Formulation and Thermal Stability
ZX-D3-03 Anionic Flocculant was added to different concentrations of ethylene glycol or methanol and placed in 50℃ oven for one week.
- Ethylene glycol
- As the level of ethylene glycol increases from 30-50%, the amount of polymer that can be used
- in the formulation decreases. Limits are:
- In 30% ethylene glycol: 30% ZX-D3-01 Anionic Flocculant max
- In 40% ethylene glycol: 25% ZX-D3-01 Anionic Flocculant max
- In 45% ethylene glycol: 20% ZX-D3-01 Anionic Flocculant max
- In 50% ethylene glycol: 20% ZX-D3-01 Anionic Flocculant max
-
Methanol
As the level of methanol increases from 30-50%, the amount of flocculant that can be added decreases only slightly compared to the much larger decrease observed in the ethylene glycol formulation. However, the level of polymer that can be added is lower in methanol than in ethylene glycol. Limits are:
- In 30% methanoll: 15% ZX-D3-03 Anionic Flocculant max
- In 40% methanoll: 15% ZX-D3-03 Anionic Flocculant max
- In 50% methanoll: 12% ZX-D3-03 Anionic Flocculant max
