Water chemistry for petrochemical heat-transfer reliability.
Product selection depends on water analysis, metallurgy, heat-transfer duty, process criticality, discharge expectations and site operating conditions.
Analysis First
Water analysis before product recommendation.
TDS, SDS and certificates are shared upon request.
Liberta supports petrochemical water systems with PureGuard® boiler, cooling and RO programs, BlancoWT® oily wastewater treatment, emulsion breaking and jar-test field translation.
Typical water-related problems
| Problem | Why It Matters | Response |
|---|---|---|
| Oxygen corrosion and condensate corrosion | Steam and condensate systems can expose carbon steel and alloys to oxygen and carbon dioxide-related corrosion. | PureGuard® oxygen scavengers, pH control and condensate treatment. |
| Cooling scale and heat-exchanger fouling | High heat duty and concentration cycles can reduce heat-transfer efficiency and increase cleaning frequency. | PureGuard® scale inhibitors, dispersants, P-Free options and cooling programs. |
| Microbiological growth / biofilm tendency | Cooling towers, stagnant zones and process water circuits may experience biofilm and deposition risks. | Site-specific biocide / biodispersant programs where registration and local requirements allow. |
| Membrane scaling and fouling | RO/NF and demineralization pretreatment failures can increase scaling, fouling and cleaning demand. | PureGuard® 7-series antiscalants, PureGuard® 3-series cleaners, BlancoWT® pretreatment routes and RO-Watel. |
| Oily wastewater and emulsion load | Oil, dispersed/emulsified hydrocarbons and process contaminants can raise COD, TSS, turbidity and downstream load. | BlancoWT® Emulsion Breaking, Coagulants, Flocculants and Jar Test Services. |
| Foam and DAF/aeration instability | Foaming can reduce separation efficiency and cause overflow or operating instability. | BlancoWT® AntiFoam selected by process behavior and bench review. |
| Sludge dewatering difficulty | Variable wastewater solids and oily residues can reduce cake dryness and increase handling cost. | BlancoWT® flocculant screening and dewatering trial support. |
System mapping
| System | Risk | Solution |
|---|---|---|
| High / medium pressure boiler | Oxygen corrosion, scale, sludge, silica sensitivity, steam quality and condensate corrosion. | PureGuard® boiler program: oxygen scavenging, alkalinity/pH, internal treatment, condensate line protection. |
| Cooling tower / condenser water | Scale, corrosion, microbiological risk, deposits and heat-transfer efficiency loss. | PureGuard® cooling program including scale/corrosion control, dispersants, biocides, P-Free options where suitable. |
| RO / NF / demineralization | Wrong product or dosage, scaling, fouling, cleaning frequency and pretreatment carryover risk. | PureGuard® antiscalants and cleaners, BlancoWT® pretreatment coagulants where carryover is controlled, RO-Watel selection. |
| Closed loop / chiller / auxiliary circuits | Corrosion, pH drift, deposits, glycol sensitivity and low-water-loss retention risks. | PureGuard® closed loop inhibitors, passivation, pH buffers, cleaning/flushing support. |
| Process / service water | Variable water quality, suspended solids, hardness, corrosion and process-specific constraints. | Site review, water analysis and custom PureGuard® / BlancoWT® product matching. |
| Oily and chemical wastewater | Oil, emulsion, color, foam, TSS, COD fractions and sludge dewatering burden. | BlancoWT® coagulation, flocculation, emulsion breaking, antifoam, color removal and Jar Test Services. |
