Decontamination of tanks and ships and reservoirs
Lipak’s strong fat solvent for oil and non-oil industries
Tanks are a major contributor to grease trap demand due to safety and long storage time. A biofilm is formed from the organic substances that have not been removed from the water. These deposited deposits and biofilms themselves lead to the formation of byproducts that degreasers and disinfectants regulated under the EPA’s Stage 2 rules contribute to refuse sub-deposit corrosion, concrete spalling, and other costly infrastructure issues. On the other hand, cleaning equipment and pipes is necessary to ensure the correct operation of industrial processes and increase the useful life of the equipment. Therefore, proper cleaning and descaling of tanks should be done annually.
Chemical tank cleaning is a process in which we use chemicals to dissolve and break down pollutants that have accumulated on the inner surface of the tanks, thereby removing deposits and residues inside the storage tanks.
In general, there are many tanks for storing chemical products that must be emptied, neutralized and cleaned. This usually occurs due to the following:
- Product change
- Safety and legal inspections
- Internal repairs
- Dirt inside the equipment
- Quality of the final product
- Tank cleaning methods
It is necessary to explain that in order to do the work correctly, the following items are analyzed before cleaning and degreasing the equipment so that we can determine the necessary practical parameters.
- Equipment size
- Internal components and geometry
- Location of equipment
- Type of stored product (chemical, corrosive, explosive, etc.)
- The need to neutralize the equipment in order to remove the contaminants
- Chemical washing process
- Final cleaning of the equipment
Tank cleaning methods
There are several available methods for cleaning tanks, here is an overview of the most common:
Pressure washing:
It is the common method used by many companies to clean and inspect tanks.
Pressure washing can be effective in cleaning surface contaminants and biofilms, but cannot remove deposits or attachment points of new biofilms. The cost of pressure washing is comparable to the cost of cleaning chemical tanks. However, pressure washing provides much lower quality results. Biofilm growth and fouling reappear and chlorine demand increases shortly after cleaning.
Diving:
Diving is a popular inspection technique that allows a company to inspect without taking the tank out of service. Services that specialize in this inspection method require significant training and certification in addition to specialized equipment. Inspection fees range from $2,500 to $5,000 depending on tank size. Cleaning is based on the amount of excess fluid in the tank. Divers attempt to remove biofilms from tank walls, but usually cannot remove sediment or calcium.
Remotely operated vehicles (ROVs):
Remotely operated vehicles (ROVs) are similar to divers and produce the same low-quality results. In this method, costs can range from $22,000 to $26,000 for each tank.
Sandblasting and re-exfoliation of the tank:
In cases where surface corrosion forces the tank to be repaired, sandblasting and resurfacing the tank is a last resort. Not only does this process cost about $250 to $290 per square foot, it also requires top-level certified tank contractors. At the same time, this process is time-consuming and intensive.
Chemical cleaning:
Chemical cleaning is a cost-effective option that provides long-lasting results and complete removal of biofilm, scale and attachment points for new biofilm growth. Using a simple spray/rinse process, dry cleaning is as easy as pressure washing, while providing excellent results. Cleaning can usually be completed in one business day and the chemicals are safe for most tank surfaces. Depending on the size and location of the tank, a cleanup can be ranged for $5,000 to $20,000. Less demand for surface chlorine, better tank inspection and delayed sediment re-formation are all other benefits of chemical tank cleaning. Ammonia-based degreasers, liquid degreasers, foam degreasers, powder degreasers, and petroleum-based degreasers are different types of industrial degreasers available in the market.
Due to the ease of use and low cost, the demand for water-based liquid industrial degreaser is increasing. Liquid-based industrial degreasers have fewer chemical additives, are environmentally friendly, and are cheaper than ammonia and oil-based degreasers.
Petroleum-based degreasers are made from petroleum products and are more effective than liquid or foam degreasers. However, they are dangerous to the environment and can cause cancer.
Demand for bio-based industrial degreasers is increasing as it replaces harmful chemicals with biodegradable ones. Bio-based industrial degreasers are safe for humans and the environment.
The possible combination of cleaners and degreasers for tanks and heavy engines available in the traditional market
Organic co-solvents: Co-solvents such as esters, ethers, ketones or alcohols
Halogenated organic solvents: Solvents such as kerosene, white alcohol and halogenated hydrocarbons
Aliphatic solvent: Solvents such as n-hexane, n-heptane, pentane, cyclohexane, cyclohexane and petroleum ether
Aromatic solvents: Aromatic hydrocarbons such as naphtha, toluene and xylene as a diluent
Halogenated solvents
These solvents have been used for a wide variety of industrial surface cleaning throughout history. Also, these solvents are easy to use in different sectors of the industry, relatively cheap, and are very effective in removing a wide range of pollutants. However, as a class of chemicals, these solvents pose concerns for the environment as well as human health and safety.
The dangers that listed for some of these halogenated chemicals include:
- Damage to the central nervous system
- Negative reproductive and developmental toxicity
- Carcinogenicity
- Respiratory effects (most halogenated solvents are stable in air and/or sediment)
- Chemicals that destroy the ozone layer
- Contribute to the production of greenhouse gases
Examples of the effects of hazardous chemicals (VOC) are:
- Skin irritation, dermatitis or skin cancer due to frequent contact with oils
- Damage to hands and eyes due to contact with corrosive liquids such a oxalic acid, sulfuric acid, hydrochloric acid, sodium and sodium triphosphate
- Asthma caused by sensitivity to hydrofluoric acid, ammonia and ammonium in traditional grease removers
- Lung diseases following exposure to dusty environments such as respirable dust
- Death or injury from exposure to toxic gases, e.g. Chlorine, ammonia, carbon monoxide
- Some chemicals also have physical hazards such as the potential to ignite or support the combustion of other chemicals (an oxidizer).
Industrial cleaners are essential in many areas of business, but because of the chemicals used in these products, they can be harmful to humans, wildlife, and the environment. While companies need these items to clean certain parts, equipment, floors, and manufacturing processes, products designed without consideration for environmental compatibility pose numerous safety concerns. Cleaning products used in industrial environments not only contain solvents with a strong and unpleasant smell, but also contain several dangerous substances. Agents designed for industrial use contain an increased amount of toxins, and as a result, the risks of improper handling are increasingly important. Eco-friendly alternatives eliminate many of the side effects of traditional chemicals used in industrial cleaning and decontamination processes. Deciding to switch to greener options will reduce health costs, meet EPA requirements, and limit the impact on the atmosphere when these essential industrial processes are carried out.
