Problems solved by technology

[0003] In the prior art, before regular maintenance of oil storage tanks or oil refining equipment in oil refining and petrochemical plants, steam purge (STEAM PURGE) is used to discharge the harmful gas remaining in the oil storage tanks or oil refining equipment into the atmosphere, Operators personally enter the oil storage tanks or oil refining equipment to carry out cleaning operations to remove oil pollutants. However, this cleaning method needs to give priority to removing the oil storage tanks or oil refining equipment before the operators enter the interior of the oil storage tanks or oil refining equipment. Harmful gases or flammable substances that exist in the existing technology, in order to carry out the removal operation, will carry out the excessive STEAM PURGE operation for a long time, so there will be air pollution, excessive energy consumption and a large amount of sludge and waste water The problem
[0004] In addition, it often happens that the exhaust of harmful gases and the removal of flammable substances in petroleum storage tanks or petroleum refining equipment cannot be completely carried out, which may endanger the lives of operators or cause adverse effects on health.
[0005] In order to solve the above-mentioned problems, the method in the prior art is to circulate the cleaning agent mixed with surfactant and enzyme to clean the inside of the petroleum storage tank or petroleum refining equipment, but in the method of the prior art, when the cleaning water When the temperature is above 100°C, the cleaning agent is poured into the petroleum refining equipment and cleaned. Under this temperature condition, there is a problem that the activity of the enzyme contained in the cleaning agent decreases, and an excellent cleaning effect cannot be achieved.

experiment example 1

[0045] Experimental example 1. Use stinky sauce to carry out separation and cleaning experiments on oil sludge (OIL SLUDGE) that often occurs in oil refining and petrochemical engineering equipment, and as follows figure 2 shown.

[0046] {- experiment summary

[0047] 1) Put the sample enzyme in the cup (BEAKER), put a stone coated with heavy oil and pour water until it is full.

[0048] 2) After fermenting in a 40°C fermenter for a certain period of time, confirm the separation state.

[0049] - sample

[0050] 1) Heavy oil (HEAVY OIL): modern oil refining AR, API=16, crude oil (CRUDE): CHA 54, DUR 42, SLE 4

[0051] 2) Enzyme (ENZYME): A: Blank, B: Bacilus, C: Smelly sauce, D: Soybean paste}

[0052] Such as figure 2 As shown, in the case of stinky sauce, even if it is in a fixed state, after 10 hours, the heavy oil adhering to the top of the pebbles is cleanly separated from the pebbles and floats on water (floating).

[0053] According to the order of C>>D>B>>A, a...

experiment example 2

[0055] Experimental Example 2. Utilize the stinky sauce made in the family and the nattokinase (NATTOKINASE) of Japanese natto to carry out oil (OIL) decomposition and separation performance, and as image 3 shown.

[0056] {- experiment summary

[0057] 1) SET-UP: 1g of stinky sauce, 1 stone coated with heavy oil, 50g of water.

[0058] 2) After fermenting in a 40°C fermenter for a certain period of time, confirm the separation state.

[0059] - sample

[0060] 1) Heavy oil (HEAVY OIL): modern oil refining AR, API=16, crude oil (CRUDE): CHA 54, DUR 42, SLE 4

[0061] 2) Enzyme (ENZYME): A: raw stinky sauce, B: dried stinky sauce, C: raw natto, D: dried natto}

[0062] Such as image 3 As shown, according to the order of B>>A>D=C, the oil (OIL) decomposition and separation performance of dried stinky soy sauce is the best, and it is shown in the following order, after 8 hours: B>>D>A>C, after After 24 hours: B>>A>D>C, after 32 hours: B>A>D=C.

[0063] Therefore, it can ...

experiment example 3

[0064] Experimental Example 3. Use smelly sauce enzyme and AMINE OXIDE (A-O, Dimethyl Lauryl AmineOXide lauryl dimethyl amine oxide) together and implement the decomposition and separation performance of oil (OIL) to improve the feasibility experiment, and as Figure 4 shown.

[0065] {- experiment summary

[0066] 1) SET-UP: 2g of stinky sauce, 1.5ml of A-O (12%), 1 stone coated with heavy oil, 50g of water.

[0067] 2) After fermenting in a 40°C fermenter for a certain period of time, confirm the separation state.

[0068] - sample

[0069] a: dried stinky sauce only, b: A-O only, c: A-O+raw natto, d: A-O+dried natto, e: A-O with dried natto aged for 8 days, f: A-O+dried stinky sauce

[0070] Such as Figure 4 As shown, the A-O sample (sample) in which the dried natto was soaked and matured for 8 days showed the best oil (OIL) decomposition and separation performance, and in the case of A-O mixing, the dried natto and raw natto had almost no performance The difference, ...

Abstract

A cleansing method of a petroleum contaminant is provided to have excellent decomposing and cleansing effects for petroleum contaminants by activating an enzyme in cheonggukjang(fermented soybean) powder. A cleansing method of a petroleum contaminant comprises: a step of obtaining a cleansing composition by mixing pure water, a cheonggukjang powder, and a surfactant; a step of mixing the composition into cleansing circulation water at 35-45 DEG C, putting the mixture into an apparatus containing petroleum contaminants, and separating the petroleum contaminants by circulating the mixture; and a step of circulating the contaminants-containing cleansing water while increasing the temperature thereof to 100-110 DEG C to separate inflammable gas from the apparatus and oxidizing harmful gas and contaminants.
