Problems solved by technology

[0006] The purpose of the present invention is to overcome the weakness of large waste of water resources and incomplete cleaning effect in the prior art to solve the oil leakage of the circulating water system, and because most of the methods for solving the oil leakage of the circulating water system in the prior art are low concentration multiples Operation, the first is to waste a lot of fresh water, and the second is the residual oily substance and biological slime on the surface of the heat exchanger, which will cause defects such as corrosion, poor heat transfer and microbial growth.

Embodiment 1

[0036] Preparation of stripping cleanser composition Q1, wherein the stripping cleanser composition contains 20% by weight of D-limonene, 10% by weight of sodium lauryl carboxylate, 20% by weight of PEG-400 and 50% by weight of Ionized water;

[0037] Add 30 mg / L of the stripping cleaning agent composition prepared above into the circulating water system, circulate to discharge after 24 hours, and replenish with fresh water until the turbidity value of the circulating water system is the same as the turbidity value before adding the stripping cleaning composition. The degree difference is between ±10%;

[0038] The turbidity and heterotrophic bacteria values ​​before and after stripping in the cleaning circulating water system of the stripping cleaning agent composition Q1 were tested, and the results are shown in Table 3.

Embodiment 2

[0040] Preparation of stripping cleanser composition Q2, wherein the stripping cleanser composition contains 10% by weight of D-limonene, 15% by weight of sodium tetradecyl carboxylate, 25% by weight of PEG-600 and 50% by weight of Ionized water;

[0041] Add 30 mg / L of the stripping cleaning agent composition prepared above into the circulating water system, circulate to discharge after 24 hours, and replenish with fresh water until the turbidity value of the circulating water system is the same as the turbidity value before adding the stripping cleaning composition. The degree difference is between ±10%;

[0042] The turbidity and heterotrophic bacteria values ​​before and after stripping in the cleaning circulating water system of the stripping cleaning agent composition Q2 were tested, and the results are shown in Table 3.

Embodiment 3

[0044] Preparation of stripping cleanser composition Q3, wherein the stripping cleanser composition contains 30% by weight of D-limonene, 5% by weight of sodium cetyl carboxylate, 15% by weight of PEG-800 and 50% by weight of Ionized water;

[0045]Add 30 mg / L of the stripping cleaning agent composition prepared above into the circulating water system, circulate to discharge after 24 hours, and replenish with fresh water until the turbidity value of the circulating water system is the same as the turbidity value before adding the stripping cleaning composition. The degree difference is between ±10%;

[0046] The turbidity and heterotrophic bacteria values ​​before and after stripping in the cleaning circulating water system of the stripping cleaning agent composition Q3 were tested, and the results are shown in Table 3.

Abstract

The invention discloses a stripping and cleaning agent composite and a use method thereof. The composite is prepared from D-limonene, polyethyleneglycol and long-chain alkyl carboxylate anionic surfactant according to the weight ratio of 1 to 0.25-3 to 0.1-1.5. The stripping and cleaning agent composite has the efficacy of oil sludge washing and the efficacy of adhesive sludge stripping, is applied to circulation water systems particularly circulation water systems where oil product leakage exists, and is good in washing effect, low in cost, small in dosage and excellent in stripping and washing performance.

Description

technical field [0001] The invention relates to a stripping cleaning agent composition for circulating water and a using method thereof. Background technique [0002] Water resources have become an important factor restricting the development of petrochemical enterprises, and water saving work is urgent. The circulating water system is a large water user. At present, increasing the concentration ratio is the most direct and effective water-saving method for circulating water. However, if the circulating water system leaks material, it needs to be replaced with a large amount of fresh water, which not only wastes a large amount of fresh water, but also greatly increases the consumption of water treatment chemicals, and greatly increases the cost. [0003] Oil leakage is a common occurrence in the circulating water system of petrochemical enterprises. The manifestations of oil leakage in circulating water are: first, the oil content of the system increases, and second, the n...
