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

[0046] Preparation of stripping cleaning agent composition Q1, wherein, the stripping cleaning agent composition contains 20% by weight of D-limonene, 5% by weight of nonylphenol polyoxyethylene ether (m=9), 5% by weight of dodecyl Sodium sulfate, 20% by weight of PEG-400 and 50% by weight of deionized water;

[0047] 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%;

[0048] 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

[0050] Preparation of stripping cleaning agent composition Q2, wherein, the stripping cleaning agent composition contains 10% by weight of D-limonene, 8% by weight of octylphenol polyoxyethylene ether (m=9), 7% by weight of dodecyl Sodium sulfate, 25% by weight of PEG-600 and 50% by weight of deionized water;

[0051] 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%;

[0052] 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

[0054] Preparation of stripping cleaning agent composition Q3, wherein, the stripping cleaning agent composition contains 30% by weight of D-limonene, 2% by weight of dodecylphenol ethoxylate (m=9), 3% by weight of dodecylphenol ethoxylate Potassium alkyl sulfate, 15% by weight of PEG-800 and 50% by weight of deionized water;

[0055] 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%;

[0056] 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 cleaning agent composition and a use method thereof, wherein, the composition contains D-limonene, polyethylene glycol and a nonionic / anionic surfactant mixture, and the D-limonene, the polyethylene glycol The weight ratio of diol to the nonionic / anionic surfactant mixture is 1:0.25~3:0.1~1.5, the nonionic surfactant is polyoxyethylene type nonionic surfactant, and the anionic surfactant It is an anionic surfactant of fatty alcohol sulfate ester salt and / or sodium 1‑octyl cetyl sulfate anionic surfactant. The peeling cleaning agent composition of the present invention not only has the performance of oil sludge cleaning, but also has the performance of slime peeling, and is applied to circulating water systems, especially circulating water systems with oil leakage, with good cleaning effect, low cost and low dosage. Less, excellent peeling and cleaning 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...
