Dry ice blasting – Overview

Dry ice blasting

Dry ice blasting is a relatively new cleaning process using solid CO2 pellets (known as dry ice). It is primarily used for industrial use in a variety of applications. The pellets sublimate (convert directly from a solid blast pellet to a vapour (CO2) leaving no residue. The process is superior to sand blasting, glass bead blasting and other types of cleaning methods for numerous reasons.

Today, the dry ice method of cleaning is quickly becoming favoured for environmental as well as production reasons. Because of tremendous environmental regulations, industry has needed to minimize wastes. Also, there is a growing consciousness that many are placing now on the global environmental impact of their production practices. However, these benefits are accentuated due to the tremendous performance gains through dry ice blasting -- little or no production downtime, quality of clean and minimized damaged to equipment.

What is dry ice

Dry ice pellets are made by taking liquid carbon dioxide (CO2) from a pressurized storage tank and expanding it at ambient pressure to produce snow. The snow is then compressed through a die to make hard pellets.

What is dry ice blasting

It is a process in which dry ice particles are propelled to supersonic speed, to impact and clean a surface. The particles are accelerated by compressed air, just as with other blasting systems.The micro-thermal shock (caused by the dry ice temperature of -79º C), the kinetic energy of dry ice pellets and the air pressure break the bond between the coating and the substrate. It pops off the coating from inside out and the air stream removes it from the surface. Industries can utilize the dry ice blasting cleaning method through equipment that fires the pellets through a blasting gun. Upon impact the dry ice sublimates (vaporizes). There are many major benefits to this cleaning process.

Dry ice blasting – Application

The use of solvents, sand blasting and a few other cleaning methods have been found inferior to dry ice blasting for a variety of reasons.Dry ice blasting applications are available to a multitude of industries offering tremendous value. In addition to the general benefits mentioned, CO2 blasting has specific benefits to some of the following industries

Dry ice Blasting – Process

With the dry ice blasting process, dry ice (CO2) particles are propelled to supersonic speed impacting and cleaning a surface. The particles are accelerated by compressed air, just as with other blasting methods. Overall, there are three steps involved in dry ice blasting. It can be viewed in diagram form.

Dry ice blasting Step #1 - Energy Transfer

Dry ice pellets are propelled out of the blasting gun at supersonic speed and impact the surface. The energy transfer knocks off the contaminant without abrasion. The force of this impact is the primary means of cleaning.

Dry ice blasting Step #2 - Micro-Thermal Shock

The cold temperature of the dry ice pellets hitting the contaminant creates a micro-thermal shock (caused by the dry ice temperature of -79º C) between the surface contaminant and the substrate. Cracking and delaminating of the contaminant occurs furthering the elimination process.

Dry ice blasting Step #3 - Gas Pressure

The final phase has the dry ice pellet explode on impact, and as the pellet warms it converts to a harmless CO2 gas which expands rapidly underneath the contaminant surface. This forces off the contaminant from behind. The contaminant is then relocated, typically falling to the ground. Since the dry ice evaporates, only the contaminant is left for disposal.

Dry ice Blasting - Benefits

Dry ice blasting benefits can be broken down into six general areas. Following each benefit is discussed:

Benefit #1 - Decreased Downtime through Cleaning In-Place

Typical cleaning procedures require that equipment be disassembled and moved to an assigned area for proper cleaning. That is not the case with dry ice blast cleaning. Equipment can be cleaned in-place and hot in most situations. Because of that, many time-consuming, labour-intensive steps which were required with other methods such as sand blasting can be eliminated including:

I. Cool down
II. Disassembly
III. Transport of the equipment to and from a dedicated cleaning area
IV. Reassembly
V. Reheating time
Dry ice blasting can shorten the downtime for cleaning from days down to hours.

Benefit #2 - Faster and More Thorough Cleaning

With dry ice blast cleaning, a superior clean can be achieved while reducing hours when compared to scrubbing with abrasive pads or wire brushes. A tremendous labour savings is accomplished. In addition, the CO2 blast method cleans in crevices that can't be reached by hand. As a result, equipment runs more efficiently and potential leaks are revealed possibly preventing major system failures

Benefit #3 - Elimination of Equipment Damage

Cleaning methods such as sandblasting leave an aggressive and abrasive effect on the surface. They can actually remove part of the surface, changing the surface structure considerably. Dry ice is non-abrasive to surfaces and does not change a surface's structure. It lifts the contaminants away. Secondly, because equipment can now be cleaned in place, potential damage from moving equipment to and from a dedicated cleaning area is eliminated.

Benefit #4 - Reduction or Elimination of Solvents

No solvents are used when using CO2 pellets. This can be a critical need for certain companies in order to comply with environmental regulations or to improve worker safety. There are no issues pertaining to toxicity.

Benefit #5 - Reductions in Waste Disposal

With other cleaning methods, whether it be with solvents, sand blasting or some other means, the cleaning agent becomes a secondary contaminant and must be disposed of as toxic waste along with the primary contaminant. However, with dry ice blast cleaning because the CO2 pellet vaporizes upon contact, the only waste created is the contaminant itself. This alone can result in significant waste reduction.

Benefit #6 - Increased Safety

CO2 blasting pellets are non-toxic, non-hazardous creating advantages to the environment, your employees, and production facility:

  • No secondary waste
  • Safe for the environment
  • Safe for employees
  • Safe for end products
  • Safe for equipment

DRY ICE BLASTING – FOUNTRY

Typical manual cleaning methods require cool down, disassembly, unproductive hours of messy hand cleaning or bead blast cleaning, and then reassembly. In addition, most traditional cleaning methods are not fully effective and often result in damage to the part of equipment.

Online Cleaning reduce production downtime

Dry ice blasting often allows the company’s production equipment to be cleaned while in operation without the need for dismantling and costly downtime a significant economic benefit

No Waste Disposal

Costs connected with the disposal of hazardous chemicals or solvents are saved because dry ice vaporizes on contact with the surface being treated . Only the dislodged coating material must be removed from beneath treated object.

Return on Investment

Dry Ice Blasting is extremely efficient, less time – consuming and very gentle to be cleaned, and therefore, the investment is paid back within short time of use.
