Abstract

Water emulsifying agent, nonflammable and nontoxic form human and sea resources, was prepd. Thus, 30l alkylbenzenesulfonic acid was added in 200ml pure water at 20-30≰C, stirred, mixed for 30-40 min, followed by adding 20l triethanolamine, and stirred completely to give pH 7-8 alkylbenzene sulfonic acid triethanol salts.

Description

Process for preparing aqueous spilled oil treatment agent

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing an aqueous effluent oil treatment agent capable of emulsifying and removing various industrial waste oils such as banca oil, diesel oil, kerosene, etc. suspended in the sea.

The area near the cash is severely contaminated by waste oil discharged from various ships or industrial factories, which is a major obstacle to environmental hygiene, and is a major obstacle to the growth of seaweeds, fish, and various microorganisms on the coast. The seriousness of the pollution is increasing day by day, the present invention is to provide a spilled oil treatment agent that can remove and purify marine waste oil by chemical for the purpose of preventing the contamination of sea water by such industrial waste oil.

The conventional oil spill oil treatment agent has a high flammability, has a risk of fire, has a toxicity and smell, and may cause problems in the growth of seafood. Almost no harm to the human body and flammable water effluent treatment agent was formed.

The effluent oil treatment agent of the present invention is characterized by the composition of the sulphate salt which emulsifies various marine effluent oils of paraffin series using the sulphate salt of hydrocarbon.

Generally, sadrates of hydrocarbons are important as excellent detergents, but in the present invention, sadrates produced by neutralizing alkylbenzine sad acid and triethanolamine have been found to be superior to other surfactants in effluent treatment. The following describes an embodiment thereof.

EXAMPLE

Prepare 200ℓ of pure clean water, add 30ℓ of alkylbenzenesulfic acid at low temperature of 20-30 ℃, and stir and mix it uniformly with stirring mixer for 30-40 minutes, then mix 20ℓ of triethanolamine and completely stir as follows. The alkylbenzenesulfonic acid triethanolamine salt of -8) is produced.

The sad salt obtained in the above reaction formula becomes the aqueous oil spill treating agent of the present invention.

When the treatment agent of the present invention is dispersed on the oil floating on the sea surface, the above-described sad acid salt can emulsify the oil on the sea and remove the oil out in a short time. The treatment effect thereof is as follows.

1. Effect of Aqueous Oil Spill Treatment Agent

Toxicity test results (measurement of TLM values) by marine organisms were excellent because barley shrimp had no mortality in 48 hours up to 3,000 ppm and 20% mortality occurred at 10,000 ppm. The test results were excellent because there was no mortality within 48 hours until the semi-lethal concentration for the toxicity test reached 50, 000 ppm.

2. Effect on Treatment Area

It is possible to treat about 1.5 pyeong of spilled oil as 1L, but there are some differences in the viscosity and quantity and thickness of spilled oil.

EXAMPLE

1. When gasoline 10D / m was spilled on the sea, this oil was completely dispersed in 5 cans (1 can = 18 liters) of the effluent treatment agent.

2. When oil spilled 10D / m was spilled on the sea, the total oil dispersion door was removed as 15Can of this oil spill application amount.

3. When banca A 10D / m was spilled on the sea, it was completely removed with 1D / m.

However, when the banca A spilled on the sea for more than 24 hours, the oil spill was contaminated by the combination of atmospheric pressure and water, resulting in 50% more oil spill.

4. Even if the oil spilled on the ship or on the deck due to carelessness, the waste oil was completely emulsified by spraying this spill oil treatment agent. Afterwards, the oil was washed with fresh water or seawater and dumped into the sea, but no pollution was caused.

As described above, the treatment agent of the present invention is very suitable as an emulsifier for industrial waste oil because it has little harm to the human body or marine resources, has no toxicity and volatility, and has good safety in handling.
