Embodiment 1

[0018] Add 306mg of sodium stearate, add 18g of water, heat to 90°C, dissolve all the solutes, vortex or stir, slowly cool down, and when it reaches about 70°C, it will suddenly solidify, and the best and longest fibers will be formed at this time. Microscopic photographs of fibers (e.g. figure 1 shown).

Embodiment 2

[0020] Sodium stearate 306mg, sodium chloride 0.6g, water 18g, heated to 100°C, the solutes were all dissolved, vortexed or stirred, slowly cooled, when it reached about 70°C, suddenly solidified, at this time the best and longest fiber. This fiber appears thicker under the microscope than the product of Example 1. Microscopic photographs of fibers (e.g. figure 1 shown).

Embodiment 3

[0022] In the product of Example 1, benzene was gradually added while shaking, and the added benzene gradually formed a sphere that could be picked up, and the final added amount reached 2.59g, and the precipitated water was slightly turbid. In the product of embodiment 2, add benzene gradually, shake simultaneously, the benzene that adds gradually forms a sphere that can be picked up, and the final addition amount reaches 3.06g, and it is clear and transparent to separate out moisture (such as figure 2 shown).

Abstract

The invention discloses a treatment method for industrial oily waste water, sea spilled oil reclaiming, waste oil in home and food manufacturing with sodium stearate. Adds some water or weak salt water to sodium stearate, heats them and stirs them and cools them to 70 deg.C, then they are frozen, and produces the sodium stearate fiber; Then adds in oil material, stirs them and makes the water oil into solid. The invention has no secondary contamination to environment.

Description

technical field [0001] The invention belongs to the technical scope of oil treatment, and particularly relates to a solidification treatment of industrial oily waste water, sea oil spill recovery, and a large amount of waste oil caused by household and food manufacturing. Edible waste oil method. technical background [0002] The oil industry has a history of decades of development. The oil industry has enriched life, but it has also become the biggest cause of environmental pollution. Among them, the discharge of oil production wastewater and the recovery of oil spilled at sea have become hot topics in environmental protection. [0003] my country's oilfields are widely distributed, and all oilfields basically adopt the water injection development method. Although part of the effluent is reinjected, the amount of discharged sewage is still considerable. Some of them can no longer meet the needs of oilfield production (Wang Zhiqiang et al. Shengli Oilfield Oil Production W...
