From an environmental protection perspective, how should acid sludge from lubricant plants be handled?

1. The method of adding a neutralizing solution is used to treat waste acid residues, producing fuel heavy oil and industrial mirabilite; this process separates sulfur from the fuel heavy oil, thereby addressing environmental pollution issues. It is a simple process that is easy to operate and energy-efficient. 2. Acid slag is used as an oxidizing agent to carry out chemical reactions with organic substances, thereby converting it into boiler fuel oil or asphalt and enabling the comprehensive utilization of acid slag. Compared with existing processes for oxidizing asphalt, this method reduces exhaust gases by 90%, increases the yield of asphalt by 5–20%, shortens the oxidation time by two-thirds, and improves the quality of the asphalt.

Gas pollution is also generated during the neutralization reaction!

To address the issue of environmentally friendly treatment of chemical waste residues generated in lubricant factories, specialty oil plants, and benzene refining processes – commonly known as \"acid sludge oil\" – this residue is a harmful mixture containing benzene compounds, colloids, and asphaltenes; it is an acidic substance with an acid content of around 20%–30%. Proper treatment of this residue can be beneficial for society, but improper handling brings only harm. Chemical waste residues are referred to abroad as \"resources in the wrong place.\" Through several years of effort, I conducted experimental analyses on \"acid sludge oil\" for up to five years, carrying out tens of thousands of tests, and obtained invention patents approved by the Intellectual Property Office. The comprehensive treatment process for \"acid sludge oil\" (patent number: 2006100440007) has been recognized, eliminating pollution associated with its treatment and ensuring no wastewater, waste residues, or waste gases are produced during production. It does not cause secondary pollution. This processing technique involves the pollution-free comprehensive treatment of acid residue oil, resulting in low-grade products, asphalt, and other derived products. The wastewater generated during production is filtered and reused, with no polluted gases emitted. This comprehensive treatment method falls outside the category of hazardous chemical processing; it operates under low pressure, ensuring safe and reliable production. It enables the reuse of acid residue oil, thus protecting the environment and maintaining ecological balance. It brings substantial economic benefits to manufacturers, eliminates pollution, and is a practice that is beneficial to both the country and its people. It is an excellent project for environmental protection and energy conservation. Zhongxinhua Jiehui Environmental Protection Technology Institute is now promoting this technology to organizations in various provinces and cities, supplying acid-resistant and durable anti-corrosion equipment. The annual production capacity is 10,000 tons to 200,000 tons of such equipment, with a large amount of acid slag being recycled as well.

There is a method; our company is focusing on this issue, as there are still some problems with decolorization

Our company faces the same problem as well; after a while, there are dozens of tons of waste that have to be handed over to others for disposal. Could you recommend some better methods?
