Steam & Thermal Operations

Optimizing heat transfer, preventing oxygen corrosion, and executing chemical descaling programs for industrial fire-tube and water-tube boilers.

Standard Boiler Water Programs

Scale & Sludge Inhibition

Phosphate-based treatments and synthetic polymer dispersants that keep calcium and magnesium hardness salts in a fluid, non-adherent sludge form for easy removal via bottom blowdown. Prevents thermal transfer resistance.

Oxygen Scavenging

Controlled sulfite and hydrazine-alternative dosing to instantly neutralize dissolved oxygen in feed water, preventing localized pitting and costly oxygen corrosion on boiler tubes.

Condensate Line Protection

Neutralizing and filming amines designed to neutralize carbonic acid in steam return loops, preventing acid attack and iron oxide contamination in the boiler feed system.

Alkalinity & pH Adjustment

Maintaining boiler water pH strictly within 10.5–11.5 to promote the passivation of iron surfaces (magnetite film formation) and protect system integrity.

Chemical Descaling & Surface Restorations

When scale has already accumulated, Kemique engineers deploy custom-blended, inhibited acid solutions. Our descaling process removes CaCO3, calcium sulfate, and iron deposits without attacking the underlying base metal.

// KEMIQUE TECHNICAL DESCALING STANDARDS:

1. Pre-inspection: Ultrasonic tube-thickness telemetry & scale sample solubility testing.

2. Chemistry selection: Inhibited HCl, Sulfamic, or organic acids matching metallurgy (copper, carbon steel).

3. Circulation control: Continuously monitoring pH, iron levels, and temperature.

4. Passivation phase: Post-acid flushing with sodium carbonate/phosphate mixtures to neutralize and establish protective magnetite film.

Technical Standards

Feed Water Hardness: < 1.0 ppm

Dissolved Oxygen: < 0.007 mg/L

Boiler Water pH: 10.5 - 11.5

TDS Blowdown Target: 2,500 - 3,500 ppm

Field Report #102

Chilled Goods Processing Plant

Problem: Sulfite drop-out causing high dissolved oxygen (> 0.2 mg/L) and initial pitting corrosion on economizer tubes.

Action: Installed automated proportional dosing linked to feedwater flow and shifted to catalyzed sodium sulfite.

Result: Dissolved oxygen controlled strictly below 0.005 mg/L. Micro-corrosion halted.
