DPF filters cleaning
The project is being implemented on the basis of MB Cargo Inc. Prerequisites: Freight transportation in the United States is a strategic direction of the economy. More than 70% of all trucking and nearly 6% of jobs in the trucking business . Almost 13 million trucks! And the number of trucks and people involved in this business is increasing every year.
PROBLEMS
The main problem of any motor transport around the world is the pollution of the environment by waste from the internal combustion engine. Up to 70% of harmful emissions into the atmosphere come from vehicles. Carbon monoxide and dioxide , nitrogen oxides , hydrocarbons , lead compounds , sulfur , aldehydes , particulate matter and carcinogens. Environmental standards for vehicle emissions in the United States require the mandatory use of DEF (DPF) filters to clean exhaust gases from harmful substances.
CURRENT CLEANING METHODS
However, the resource of these filters is limited , and the cost of replacement is significantly high , which often leads to irregular replacement or attempts to clean the complex filtration system , which results in temporary , poor quality and, at the same time, polluting the environment with cleaning waste. With water purification , all pollutants enter the sewer system and eventually pollute the soil and groundwater. High consumption of water and electricity. During heat treatment , all pollutants enter the air and soil. High consumption of electricity , gas , additional pollution from combustion products.
Our solution
First of all, it is an absolutely ecological way of cleaning! There are no emissions into the environment, cleaning waste is accumulated in a special sealed unit and can be reused, for example, in cartridges for printing on printers , etc. Secondly, this method does not destroy or damage the coating. platinum triggers a chemical reaction with the decomposition of solid elements without the formation of new elements, which ensures cleaning efficiency and repeated use. Thirdly, in exhaust gases contain particles composed of complex carbon compounds with various components. The sizes of these fragments are from 10 nm to 1 µm. The emission of these substances causes significant harm to the environment. The DPF system is a cylindrical configuration unit with a ceramic, fine-pored honeycomb structure inside and practically inaccessible for washing with water, due to the physically larger size of the molecule, but possible for our system and solvent. And finally, the cost of cleaning is lower than the current prices on the market, which will allow drivers to save significantly, and therefore to clean more regularly, especially since a dirty filter, in addition to emissions into the atmosphere, increases fuel consumption and reduces engine power, and can also lead to the operator being punished with significant fines and a ban on using this vehicle.
Environmental Benefits of the Method
Liquid carbon dioxide (CO₂) is one of the most environmentally friendly solvents. Unlike chemical reagents, CO₂ is non-toxic, non-flammable, and leaves no harmful residues. When used in a closed extraction system, cleaning byproducts can be collected and disposed of without entering the environment. This eliminates air, water, and soil pollution, which is particularly important given increasingly stringent environmental regulations. Scientific research shows that subcritical CO₂ has high solvency, enabling it to effectively remove contaminants without generating secondary waste. According to a study published on ScienceDirect, using CO₂ for cleaning industrial equipment can reduce carbon dioxide emissions by 30-50% compared to traditional methods. This makes the method especially attractive for countries with strict environmental standards. For example, the U.S. Environmental Protection Agency (EPA) notes that the adoption of environmentally friendly technologies in the transportation sector could reduce particulate emissions by 90% by 2030. The use of CO₂ cleaning aligns with the strategy of reducing carbon emissions and improving energy efficiency in transportation.
Conclusion
Cleaning DPF filters using liquid carbon dioxide represents a modern, environmentally safe, and economically efficient solution. The method significantly reduces operating costs, extends filter lifespan, and minimizes environmental impact. Given the tightening of environmental standards in North America and Europe, the adoption of this technology could be a crucial step toward sustainable development in the transportation industry.
