Key Considerations for Equipment Selection
When choosing acetone recovery equipment, the following points need to be given particular attention:
What is the target for treatment: Is it waste liquid or waste gas? What are the components and concentrations? What are the main impurities? (For example: acetone-water mixture, acetone cleaning solution containing resin, etc.)
Processing capacity: How much waste solvent/waste gas needs to be processed per hour or per day?
Recovery requirements: The purity requirements for recovered acetone (such as 99%, 99.5% or higher) and the recovery rate requirements (such as over 95%).
Safety and explosion prevention: Acetone is a highly flammable and explosive substance (flash point -20℃). All electrical components, motors and instruments must be explosion-proof types that meet the standards. The equipment should be equipped with good static elimination, nitrogen protection, explosion relief devices and other safety measures.
Material: The parts that come into contact with acetone are usually made of stainless steel (such as 304, 316L) to ensure corrosion resistance and product cleanliness.
Energy consumption: Examine the heating method of the equipment (electricity, steam), cooling method, and whether it has a heat energy recovery design (such as preheating the feedstock).
Environmental compliance: The equipment should ensure that exhaust emissions meet standards and must not cause secondary pollution.
Degree of automation: Manual, semi-automatic or fully automatic control can be selected based on labor costs and management requirements.
Operation and Safety Precautions
Strict explosion prevention: No smoking or open flames are allowed in the operation area. The equipment must be reliably grounded.
Closed operation: The entire system should maintain good airtightness to prevent the leakage of acetone vapor.
Control the temperature: The distillation temperature should not be too high to prevent the decomposition of acetone or potential safety hazards. Vacuum operation can effectively reduce the operating temperature.
Nitrogen protection: Use nitrogen for displacement protection during startup, shutdown, or when there is a possibility of contact with air.
Personal protection: Operators must wear chemical-resistant gloves, goggles and gas masks.
Regular maintenance: Inspect valves, seals, and instruments, clean up residues, and ensure the equipment is in the best condition.
Main application industries
Chemical and pharmaceutical: Recovery of reaction solvents and cleaning solvents.
Paints, inks and adhesives: Recovery of waste solvents from production equipment and container cleaning.
Electronic industry: Recovery of acetone after cleaning of precision parts (such as LCD, semiconductors).
Laboratory: Recovery of waste acetone generated by universities, research institutes and testing institutions.
Film coating, printing and coating: Recovery and treatment of acetone waste gas generated during the production process.
