Key benefits include faster dissolution, elimination of dry pockets, improved safety, reduced batch time, and consistent product quality. Multiple powder suction methods such as jumbo bags, silos, hoppers, and flexible hose connections are supported, along with robust
Caustic Lye Preparation
Caustic Lye Preparation (NaOH Flakes / Pearls)
Caustic lye preparation involves dissolving solid sodium hydroxide flakes or pearls into water while managing one of the most exothermic dilution reactions in chemical processing. Traditional tank dumping often leads to local overheating, crust formation, operator exposure, and inconsistent concentration.
The Wahal Liquid Powder Mixer (LPM) enables controlled, dust-free powder induction directly into a high-energy liquid zone. The CNC machined rotor–stator generates intense local turbulence, ensuring instant wetting of caustic flakes and uniform heat distribution across the batch.
Typical process parameters include solids addition rates of 2–6 TPH, liquid recirculation of 20–80 m³/hr, and final concentrations up to 50%. Automated powder dosing ensures that induction rate is matched with cooling capacity, preventing runaway temperature rise.
- 3. Addition of Chemical Additives:A wide variety of chemical additives are incorporated to achieve specific functions. These are typically added and mixed in stages:
- Viscosifiers (e.g., Polymers like Xanthan Gum, Guar Gum, CMC, PAC): These increase the fluid’s viscosity for cuttings transport and suspension. Wahal high shear mixers helps to properly dissolve and hydrate these polymers.
- Fluid Loss Control Agents (e.g., Cellulose derivatives, Starches, Resins): These minimize the loss of fluid into permeable formations.
- Shale Inhibitors (e.g., Salts like KCl, Glycols, Amines): These prevent swelling and disintegration of reactive shales.
- Emulsifiers and Wetting Agents: Essential for oil-based and synthetic-based muds to create stable emulsions of oil and water/brine and to ensure solids remain oil-wet.
- Thinners and Dispersants (e.g., Lignosulfonates, Tannins): Used to control viscosity and prevent flocculation of solids.
- Lubricants (e.g., Beads, Esters, Graphite): Reduce friction between the drill string and the borehole.
- Corrosion Inhibitors: Protect the drilling equipment from chemical attack.
- pH Control Agents (e.g., Lime, Caustic Soda, Soda Ash): Maintain the desired pH for optimal fluid performance and to activate certain additives.
- Defoamers: Prevent or reduce foaming of the drilling fluid.
- Biocides/Preservatives: Prevent microbial growth in water-based muds.
- This commitment to customer service underscores Wahal’s reputation for reliability and excellence.
