Problems solved by technology

[0002] At present, the methods commonly used for oily sludge both internationally and domestically include incineration, biological method, hot water washing method, coking method, etc. In the actual oil sludge treatment process, thermal analysis is a relatively advanced method, which can recover the oily sludge containing Sludge heat and other available components, but the biggest disadvantage of thermal analysis technology is that it will generate hazardous waste during construction, which will increase the economic cost of treatment
At present, there is still a big gap between the treatment and utilization of oily sludge in my country compared with the advanced level in foreign countries: the technology of treatment equipment is backward, the technology is not matched, and the investment in treatment is insufficient, which will cause environmental pollution and huge waste of resources.

Embodiment 1

[0016] A: 20% citric acid, 10% emulsifier, 35% penetrant, 15% tetrasodium edetate, 5% inorganic salt, 8% sodium silicate, 5% alkali, and the rest is water, the weight percentage of each component The sum is one hundred percent.

[0017] The preparation method of the medicament is as follows: first dissolve tetrasodium edetate and water in a reaction kettle equipped with a stirrer according to the mass percentage, and then weigh citric acid, emulsifier, penetrant, inorganic salt, and sodium silicate according to the mass percentage. , alkali and other six chemical agents are mixed, and finally put them into the reactor to react together. The controlled reaction temperature is 40±5°C, and the constant temperature reaction is 30min~1h. Then take out a little of the prepared agent and put it into the sandy soil of Kuwait In the experiment, the pollution degree of the sandy soil in Kuwait before the cleaning experiment was 6.66213%, while the pollution degree after cleaning was 0.6...

Embodiment 2

[0019] A Citric acid 11%, emulsifier 3.5%, penetrant 25%, tetrasodium edetate 6.5%, inorganic salt 1.5%, sodium silicate 5%, alkali 0.5%, the rest is water, the weight percentage of each component The sum is one hundred percent.

[0020] The preparation method of the medicament is as follows: first dissolve tetrasodium edetate and water in a reaction kettle equipped with a stirrer according to the mass percentage, and then weigh citric acid, emulsifier, penetrant, inorganic salt, and sodium silicate according to the mass percentage. , alkali and other six chemical agents are mixed, and finally put them into the reactor for common reaction. The controlled reaction temperature is 40±5°C, and the constant temperature reaction is 30min~1h. The experiment was carried out in the soil. The pollution degree in the Shengli Senuo sandy soil before the cleaning experiment was 30.4404%, while the pollution degree after cleaning was 1.24232%.

Embodiment 3

[0022] A 15% citric acid, 7% emulsifier, 30% penetrant, 10% tetrasodium edetate, 3.5% inorganic salt, 6% sodium silicate, 2.5% alkali, the rest is water, the weight percentage of each component The sum is one hundred percent.

[0023] The preparation method of the medicament is as follows: first dissolve tetrasodium ethylenediaminetetraacetic acid and water in a reaction kettle equipped with a stirrer according to the mass percentage, and then weigh citric acid, emulsifier, penetrant, inorganic salt, and sodium silicate according to the mass percentage , alkali and other six chemical agents are mixed, and finally put them into the reactor to react together. The controlled reaction temperature is 40±5°C, and the constant temperature reaction is 30min~1h. Then take out a little of the prepared agent and put it into the Shanghai clay soil The experiment shows that the pollution degree of Shanghai clay soil before cleaning experiment is 7.46588%, while the pollution degree after c...

Abstract

The invention discloses a formula and a preparation method of an oily sludge demulsifier. The oily sludge demulsifier is prepared from mixing the following components in percent by weight: 11 percent to 20 percent of citric acid A, 3.5 percent to 10 percent of emulsifier, 25 percent to 35 percent of penetrating agent, 6.5 percent to 15 percent of ethylenediamine tetraacetic acid, 1.5 percent and 5 percent of inorganic salt, 5 percent to 8 percent of sodium silicate, 0.5 percent to 5 percent of alkali, and the balance of water, wherein the sum of the weight percentage of the components is 100 percent. Compared with the prior art, the formula provided by the invention is scientific in matching, simple in process and low in manufacturing cost. The oily sludge demulsifier provided by the invention is used for oily sludge treatment, and capable of reducing oily sludge pollution and improving the effective availability of petroleum hydrocarbon, and can provide technical reserve for soil remediation in the future.
