Oil & Gas.

CleanOxide 75 is a practically pure solution of chlorine dioxide – one of the most powerful and safe disinfectants known as well as a highly effective oxidising agent for converting sulphide to sulphate. Chlorine dioxide is also very efficient at oxidising sulphides to sulphate; thus, providing a method of simultaneously controlling sulphur reducing bacteria and removing sulphides. Sulphides are formed by the action of sulphate-reducing​ bacteria found in oil well systems. The sulphides react with iron in the water to form insoluble iron sulphide that in conjunction with bacterial biofilm acts as a plugging agent.

The presence of sulphides also causes what is known as sour crude which is of lower quality and more expensive to refine. Controlling sulphide levels in oil and gas wells is not only necessary for ensuring a higher quality product and to minimise plugging, it is also necessary for the protection of personnel from exposure to extremely toxic hydrogen sulphide gas. CleanOxide 75 can also be used in place of or in addition to conventional biocides to control bacteria in drilling mud and hydraulic fracturing fluids, downhole cleaning of injection and disposal wells, and as an emulsion breaker.

Corrosion

The use of oxidising biocides such as hypochlorite and ozone is associated with increased rates of corrosion. Chlorine dioxide generated by traditional methods also suffers from this problem because of free chlorine and other corrosive by-products formed in the manufacture. Chlorine dioxide itself is not a corrosive substance. CleanOxide 75 is a solution of pure chlorine dioxide. CleanOxide 75 does not contain any corrosive by-products nor does it break down to form any corrosive compounds. Even at elevated levels, the use of CleanOxide 75 will not result in increased corrosion.

Control of Biofilm

CleanOxide 75 controls biofilm more effectively than chlorine or non-oxidising biocides even when dosed intermittently. The reason why CleanOxide 75 is so effective at controlling biofilm is because it is a solution of pure chlorine dioxide in water. Chlorine dioxide does not hydrolyse in water and does not react with the polysaccharides holding the biofilm together. Consequently, it is able to diffuse deep into the biofilm layers destroying the microorganisms that are present. Non-oxidising biocides are generally ineffective at controlling biofilm.

Environmental Impact

The environmental impact of chemical discharge is of major concern to the oil and gas industry. CleanOxide 75 has a much lower impact than alternative chemicals for a number of reasons:

  • CleanOxide can replace the use of persistent organic compounds such as biocides and hydrogen sulphide scavengers. Many non-oxidising biocides such as isothiazolinones are extremely toxic compounds and often of relatively low biodegradability.
  • CleanOxide is extremely efficient and thus reduces overall chemical demand.
  • CleanOxide does not form organochlorine compounds by reaction of organic compounds with chlorine. Organochlorine compounds are both
    suspect carcinogens and known persistent pollutants.
  • CleanOxide does not form chloramines by reaction with ammonia.
  • CleanOxide has no potential to bioaccumulate.
  • CleanOxide degrades rapidly at the recommended dose rates (typically <72hours) to harmless inorganic compounds.

CleanOxide 75 as a Biocide

CleanOxide 75 is effective as a biocide at concentrations of 0.1 to 0.3 mg/L for potable water. Higher dose rates (up to 3 mg/L or higher) may be used for other applications depending on the quality of the water, bacteria loading and degree of control required. If the water to be treated is high in sulphides then the dose rate is calculated according to the sulphide demand and a residual concentration of chlorine dioxide for control of biological contamination.

Benefits of CleanOxide Chlorine Dioxide

  • Non-corrosive with steel, metal, aluminium, plastic & fibreglass at the recommended dose rates.
  • Removes biofilm slime from water tanks and pipes at shock dosing rates.
  • Oxidises iron & manganese.
  • 100% bio-degradable.
  • Sustainable, environmentally friendly.
  • Safe for our oceans and natural water ways, leaves no harmful residues in water after 72 hours of treatment.
  • Broad spectrum disinfectant effective against bacteria, bacterial spores, fungi, protozoa, viruses, biofilm & algae.
  • Effective over a broad pH range of 4 to 10.
  • 10 times more powerful than chlorine.
  • Effective at lower dose rates than chlorine & hydrogen peroxide.
  • Does not contain free chlorine.
  • Does not react with ammonia & does not produce toxic compounds in contact with organic materials present in water.
  • Effective against biofilm because it exists in solution as a dissolved gas. The dissolved gas is able to diffuse into the biofilm where it can destroy the micro-organisms responsible for the biofilm.
  • Micro-organisms do not develop resistance to CleanOxide.
  • Safe for consumption and approved for use in Australia and around the world.
