NORM (Naturally Occurring Radioactive Material) contaminated equipment needs cleaning to reduce or remove radioactive residue to a safe level. CO2Blast Ltd. specializes in removing scale buildups and deposits from downhole and topside process equipment.
Naturally occurring radioactive materials (NORM) and technologically enhanced NORM (TENORM) are materials enriched with radioactive elements like uranium, thorium, and potassium, found in industrial wastes or by-products. These elements are brought to the surface through human activities like oil and gas exploration or mining. TENORM examples include coal ash from power plants. While individual exposure is usually minimal, high concentrations can require regulation and control.
Dry Ice Blasting for Norm Decontamination
Dry ice blasting effectively removes naturally occurring radioactive materials (NORM) such as uranium, thorium, radium, and their decay products from surfaces. CO2 blast cleaning uses solid carbon dioxide pellets propelled by compressed air to gently clean surfaces without the need for harsh chemicals or water. The process sublimates on contact, leaving no residue behind and minimizing the risk of spreading radioactive particles.
Using dry ice blasting for NORM decontamination ensures compliance with industry regulations and safety standards. This is crucial for industries such as oil and gas, mining, and other sectors where radioactive contamination is a concern. The effectiveness of dry ice blasting can be documented, providing clear records of decontamination processes for regulatory compliance and audits.
Norm decontamination in action
Benefits of Using Dry Ice Blasting for NORM Decontamination
- The dry ice blasting process can reach and clean difficult-to-access areas, ensuring a comprehensive decontamination.
- Unlike other abrasive cleaning methods, dry ice blasting does not wear down or damage surfaces. This is particularly important for delicate or sensitive equipment that needs to maintain its structural integrity.
- CO2 blast cleaning can be used on a variety of materials, including metals, plastics, and composites, without causing harm.
- Dry ice blasting is an environmentally responsible choice for decontamination processes.
- No secondary waste or need for additional cleanup.
- Using dry ice blasting for NORM decontamination is quick and efficient, reducing downtime and labour costs.
- Equipment and surfaces can often be cleaned in place without the need for disassembly.
- By eliminating the need for chemical cleaners, dry ice blasting reduces the risk of chemical exposure to workers, enhancing workplace safety.
- Dry ice is non-conductive, making it safe for use around electrical components and equipment without the risk of electrical hazards.
Applications of Dry Ice Blasting for NORM Decontamination
- Oil and Gas Industry: Decontaminating pipelines, storage tanks, drilling equipment, and production facilities.
- Mining Operations: Cleaning machinery, transport vehicles, and processing equipment.
- Industrial Facilities: Decontaminating manufacturing and processing equipment exposed to radioactive materials.
- Environmental Cleanup: Remediation of sites and equipment contaminated with NORM.
By incorporating dry ice blasting into NORM decontamination procedures, industries can benefit from a safe, effective, and environmentally responsible cleaning method that ensures compliance with safety regulations and enhances the longevity and performance of equipment.
