PERACETIC ACID FOR INDUSTRIAL, OIL & GAS APPLICATIONS

Peracetic Acid for Industrial Wastewater Applications

Introduction

Peracetic Acid (PAA) is an organic peroxide compound with the formula CH₃CO₃H. It is environmentally friendly as it hydrolyzes to acetic acid and hydrogen peroxide in water. It is a broad-spectrum biocide with a fast reaction time in minutes and leaves no harmful by-products.

Peracetic acid is a strong oxidant and disinfectant with oxidation potential higher than that of chlorine or chlorine dioxide. PAA is available in the form of equilibrium mixture which also contains hydrogen peroxide, acetic acid (vinegar) and water as shown by the following equation…

Examples of Microbiological Control Applications

Sulfate Reducing Bacteria (SRB) Control
Broad spectrum control for sulfate-reducing and aerobic bacteria and does not interfere with other frac fluid chemistries. Environmentally safe alternative to chlorine and glutaraldehyde.

Frac Water Ponds
PAA has been shown to significantly reduce or eliminate Sulfate Reducing Bacteria and their byproduct hydrogen sulfide, eliminating sulfide odor, increasing worker safety, and protecting oilfield assets.

Wastewater Disinfection
Replaces chlorine, sodium hypochlorite, and is as a low-capital alternative to UV, chlorine dioxide and ozone. The PAA treatment decomposes into
biodegradable components and does not create chlorinated compounds or harmful disinfection by-products.

Biofouling Control in Paper Machine White Water Circuits
Prevents microbial contamination in the recirculation water and removes slime
