Abstract

PROBLEM TO BE SOLVED: To produce a processing agent highly miscible with waste oil and excellent in reactivity of quick lime at a reduced cost. SOLUTION: This water-rich waste oil processing agent is obtained by surface-reforming the quick lime fine powder with a higher fatty acid and silicone. A highly reactive quick lime having >=650ml activity is preferably used as the quick lime. A 16-18C higher fatty acid such as stearic acid is preferably used as the fatty acid. This water-rich waste oil processing agent is produced by adding the higher fatty acid to quick lime, then adding silicone and water and violently agitating the admixture.

Embodiments of the present invention will be described below in detail. The quicklime used as a raw material is finely powdered soft-burned quicklime, and preferably has an average particle diameter of 0.5 mm or less, more preferably 0.1 mm or less. The lower limit of the average particle size is about 0.01 mm. Also,
It is desirable that the quicklime has a high reactivity of 650 ml or more. The upper limit for soft-baked quicklime is 800
It is about ml. This activity level is based on the following reference test method of the Japan Lime Association. (1) OH in water coverage quicklime - the dissolution rate was titrated with hydrochloric acid 4N, is intended to know the reactivity. (2) Sample After crushing lump quick lime roughly, it sifts with a 1000-micrometer sieve. Then, 100 g of quicklime that has passed through the sieve is sampled. (3) Operation (a) Put 4 liters of pure water in a beaker and keep the temperature at 40 ° C.
To keep. (B) Set the center of the beaker so that the distance between the bottom of the three blades of the stirrer and the bottom of the beaker is 20 mm. (C) Start stirring and add 2-3 drops of phenolphthalein indicator. (D) Put the measurement sample at once and press the stopwatch at the same time. (E) After 1 minute, 4N hydrochloric acid was added dropwise so that the solution remained slightly red, and the amount of the added solution was recorded every 1 minute.

This operation is continued for 10 minutes, and the activity is defined as the total amount (ml) of 4N hydrochloric acid. Next, higher fatty acids are quick lime surface modifiers, and higher fatty acids having 16 to 18 carbon atoms such as stearic acid, palmitic acid, and oleic acid, or a mixture thereof are used. Further, beef tallow, tempura oil, cottonseed oil, olive oil and the like containing this higher fatty acid can also be used. This higher fatty acid is preferably added in the range of 0.1 to 5% by weight with respect to quicklime. If it is less than 0.1% by weight, the miscibility with the oil content when the treating agent is added to the high water content waste oil becomes low, or the separability of water decreases. When it exceeds 5% by weight, reactivity in quick lime hydration reaction decreases.

Silicone is also a surface modifier for quicklime, which suppresses the reaction of quicklime with water and smoothes the contact with oil. Polydimethylsiloxane is usually used as the silicone. As the silicone, for example, an aqueous solution such as an aqueous solution, emulsion or suspension containing 10% of silicone is used. The amount of silicone added is preferably in the range of 0.015 to 0.3% by weight with respect to quicklime. If it is less than 0.015% by weight, the miscibility with the oil content when the treating agent is added to the high water content waste oil is low and the separability of water is lowered. When it exceeds 0.3% by weight, the reactivity in the hydration reaction of quicklime decreases.

Next, a method for producing a high water content waste oil treatment agent will be described. The high water content waste oil treatment agent is produced by adding a higher fatty acid to quicklime, then adding silicone and water and stirring the mixture. More specifically, first, higher fatty acid is added to quicklime and mixed. As a result, the surface of the quicklime is partially covered with a part of the higher fatty acid. Then
By adding silicone and water and stirring vigorously, quicklime and water react to generate heat. Due to the heat of reaction, the remaining higher fatty acid and silicone are coated on the surface of the quicklime, and a powder of the waste oil treatment agent is obtained.

Next, a method of using the high water content waste oil treatment agent will be described. When a waste oil treatment agent as described above is added to a high water content waste oil, the treatment agent is sufficiently mixed with the oil component in the waste oil due to the higher fatty acid and silicone coated on the surface of the treatment agent, and quick lime and water are mixed. The reaction is suppressed. In addition, these miscibility and reactivity are determined by the contents of higher fatty acid and silicone in the treating agent.

After the treatment agent is mixed, oil and water are separated, so that this water is separated as necessary. And, if the oil content after water separation is maintained as it is,
After 5 to 10 minutes, due to the high reactivity of quick lime, quick lime reacts with water instantly, the heat of reaction evaporates water to reduce water content, and highly water-containing waste oil is pulverized. As a result, a powder containing only oil is obtained.

When waste oil having a high content of chlorine (Cl) or sulfur (S) is treated with the powdery waste oil treating agent, chlorine gas generated when the fine powder obtained after the treatment is directly sprayed and burned. A harmful gas such as (Cl 2 ) or sulfurous acid gas (SO 2 ) is generated. However, the calcium content of quicklime in the waste oil treatment agent can react with these harmful gases to absorb and remove the harmful components, so that the burning treatment can be easily performed.

That is, when 50 parts by weight of a waste oil treating agent was mixed with 100 parts by weight of waste oil and left standing, quick lime reacted violently with water after 5 minutes. Due to the heat of the hydration reaction, water was evaporated and the waste oil became fine powder. (Example 2) As quicklime, the average particle size is 0.05 mm
Then, the one having an activity of 300 ml was used. In addition, stearic acid and a silicone antifoaming agent (containing 15% of silicone) were used.
