Hydrocarbon cleaning agent waste liquid treatment
1. Combustion treatment
The cleaning plant becomes its fuel when it has a boiler, and some are specially introduced into waste oil boilers and waste oil furnaces. When the amount of waste liquid is small, soak it with a rag and burn it with an incinerator. When burning in your own company, you must consider the gas emitted by combustion. The combustion of the cleaning agent fraction does not produce a large amount of harmful substances. Since the additives in the processing oil are also burned at the same time, the processing oil that does not generate harmful gases during combustion should be selected.
2. Entrust a professional waste disposal company for disposal
When using chlorine- or fluorine-containing cleaning agents, you must entrust a special industrial waste disposal company to deal with them. Depending on the national conditions, there may be different treatment methods, but all should be handled in strict accordance with legal standards.
3. Use a hydrocarbon recovery machine for recycling
Hydrocarbon recovery machine is a more widely used, more economical and practical waste hydrocarbon recovery method, which uses the principle of heating distillation, the waste hydrocarbon is indirectly heated to reach the boiling point, and then flows out through cooling liquefaction, which is clean after recovery Non-polluting solvent. The recovered hydrocarbons can still meet the requirements of cleaning products and can be used as cleaning agents to clean products.
Questions and answers about hydrocarbon cleaning agents
What is hydrocarbon
Organic compounds composed of only two elements, carbon and hydrogen, are called hydrocarbons, or hydrocarbons. It contains alkanes, alkenes, alkynes, cyclic hydrocarbons and aromatic hydrocarbons, and is the matrix of many other organic compounds.
Hydrocarbons can be divided into: open-chain hydrocarbons, alicyclic hydrocarbons, aromatic hydrocarbons.
a. Open-chain hydrocarbons (carbon atoms in hydrocarbon molecules are combined in an open chain) {saturated hydrocarbons (alkanes), unsaturated hydrocarbons [olefins and polyolefins (containing carbon-carbon double bonds, unstable), alkyne and polyalkynes (containing Carbon-carbon triple bond, more unstable)]
b. Alicyclic hydrocarbons [cycloalkanes (cyclopropane), cycloalkenes, cycloalkynes]
c. Aromatic hydrocarbons [monocyclic aromatic hydrocarbons (benzene and its homologues), fused ring aromatic hydrocarbons (naphthalene, anthracene and other fused ring aromatic hydrocarbons and their homologues), polycyclic aromatic hydrocarbons (polycyclic aromatic hydrocarbons and their homologues)]
What is a hydrocarbon cleaning agent
The main component of the hydrocarbon cleaning agent is alkane, which is a narrow fraction with a volatility of 150-190°C that is specially cut out by petroleum after rectification in a refinery, and then undergoes a process such as hydrogenation, desulfurization, dearomatic hydrocarbon removal Impurities, decolorization and other refining treatments to obtain saturated alkane, and then compounded with stabilizers, antioxidants, washing aids, prepared into a hydrocarbon cleaning agent. The main components of the hydrocarbon cleaning agents that are widely used in the industry today are C9-C11 saturated straight-chain alkanes or few-chain saturated alkanes. Therefore, the hydrocarbon cleaning agent has stable performance, odor water, complete volatilization, suitable for high-precision precision cleaning, and high distillation recovery rate.
Hydrocarbon cleaning agent has gradually become an important industrial cleaning agent due to its good environmental protection characteristics and cleaning ability. There are many problems with ordinary hydrocarbon cleaning agents. The distillation range is wide, the composition is complex, the molecular structure is irregular, and aromatic hydrocarbons are highly toxic. Among them, the light weight reduces the flash point of the cleaning agent, while the heavy weight makes the cleaning power and dryness worse. Choosing narrow-distillation solvents with a distillation range of 150 to 190°C, combined with the four major factors (air, metal, water, impurities) that cause the acidification of solvents in industrial cleaning, a special stabilizer for metal cleaning agents is added, which can prevent solvent decomposition and cause decomposition The acid is neutralized in the initial stage, and has super acid resistance, ensuring that the cleaning material is not corroded. It has been widely used in hardware, jewelry, clocks, electronics, electrical, liquid crystal, semiconductor and other industries, can effectively remove all kinds of oil, grease and soldering resin, polishing wax, etc.
What are the hazards of hydrocarbon cleaning agents to the human body
Probably now people commonly use washing powder, metal cleaning agents, etc. should be included in the category of hydrocarbon cleaning agents. If these cleaning agents are harmful to the human body, there may be harmful impurities in the raw materials. After cleaning, the cleaning agent residues on the items, The stimulation of hydrocarbon cleaning agent on human skin and nasal mucosa, the pollution of the environment with the cleaning agent, and the pollution of the environment during the manufacturing, transportation and storage of hydrocarbon cleaning agent. These will directly, indirectly, be heavy or light, or endanger human health immediately or in the long run.
What does the flash point of hydrocarbon cleaner mean?
The flash point of the solvent is a safety indicator, and it can also express the volatilization rate of the solvent, which means that when the solvent rises to this temperature, a flash explosion can occur when there is an open flame near the solvent, so the general environmental requirements are lower than the flash point of the solvent , Or strictly control open flames and static electricity on site. Regarding the flash point of the hydrocarbon cleaning agent, it should be higher than the ambient temperature of your use, 35 in the north and 40 in the south. This is generally safer.
General manufacturers say hydrocarbons: they are derived from petroleum, carbon and hydrogen compounds. This cleaning agent is not suitable for heating cleaning. It has a flash point like gasoline products. The so-called flash point refers to: the cleaning agent is heated in a container of a specified structure to evaporate combustible gas and the air near the liquid surface to mix, The fuel temperature at which a certain concentration can be ignited by Mars. Therefore, be sure to use fire safety when using this product.
The difference between hydrocarbon cleaning agent and water-based cleaning agent
Hydrocarbon-based cleaning agent: The distillate solvent obtained by distilling crude oil is called petroleum-based, petroleum-based hydrocarbon, hydrocarbon-based, hydrocarbon (hydrocarbon), industrial gasoline, etc. The definition is still unclear. Hydrocarbons, as the name suggests, are just compounds composed of two elements. In the past, the kerosene refined from crude oil was used directly as a cleaning agent. Due to its odor, ignitability, and dryness, it was gradually not used.
Water-based cleaning agent is the wetting, emulsifying, penetrating, dispersing, solubilizing, etc. of surfactants, emulsifiers, penetrants, etc. to achieve the cleaning of oil stains and grease; the meaning of water-based cleaning agent can also be simply said It is a water-miscible water, which can be diluted with water to be used as a cleaning agent. For example, a civilian detergent can also be said to be a water-based cleaning agent. But the water-based cleaning agent mentioned here is mainly used for industrial cleaning.
What hydrocarbon cleaning agent is mainly used for cleaning
In the industries of hardware, jewelry, watches, automobiles and motorcycles, aerospace, electronics, electrical, liquid crystal, semiconductor, etc., REMA can effectively remove all kinds of oil stains, grease and soldering resin, polishing wax, etc.
Hydrocarbon cleaning agent is a highly efficient and environmentally friendly hydrocarbon cleaning agent with excellent safety, environmental protection and cleaning ability. It is non-corrosive to metals and can meet the needs of parts cleaning in many fields. This product also has a certain anti-rust effect.
Use range of hydrocarbon cleaning agent
1. Cleaning copper, aluminum and its alloys, glass and other stains and all kinds of resin, ink, aluminum, stainless steel, industrial grease, etc.
2. Clean oil and dust pollution of laptop and mobile phone accessories, terminals, micro motors, bearings, CNC workpieces, die casting and other products.
3. Cleaning stainless steel precision machined parts and other products with strict surface requirements, such as oil stains and stains.
Is white oil a hydrocarbon cleaning agent?
White oil is not a hydrocarbon cleaning agent. The main component of the hydrocarbon cleaning agent is alkane, which is composed of two elements of carbon and hydrogen. The main component of white electric oil is n-hexane, and it is very toxic to the human nervous system and has a long incubation period, which can cause paralysis of the lower limbs.
Can hydrocarbon cleaning agent be used with water?
Hydrocarbon cleaning agents are insoluble in water, so they cannot be mixed with water.
How many kilograms is 1 liter of hydrocarbon cleaning agent
1 liter = 0.75KG. The calculation process is as follows: 1 liter = 0.001 cubic meter, the density is: 0.75*10^3 kg/cubic meter, mass = 0.001M^3*750KG/M^3=0.75KG;
Does the hydrocarbon cleaner have anti-oxidation function?
Hydrocarbon cleaners have no antioxidant function. Hydrocarbon cleaning agent will remove the water on the surface of the metal and reduce the possibility of corrosion. But after it volatilizes, the metal is equivalent to being exposed in the air, and it can be oxidized. Therefore, the hydrocarbon cleaning agent has no anti-oxidation function. But if there is a targeted addition of antioxidants.
