Problems solved by technology

[0008] The biosurfactants used in the field of tertiary oil recovery have so far been limited to the metabolites produced by microbial fermentation, but microbial flooding also has its own defects, such as oil layer temperature, organic carbon source, and reservoir fluid toxicity affect microbial growth, and oil recovery microorganisms Difficult to separate, and microbial metabolites corrode pipelines and oil production equipment, etc., to a considerable extent restrict the application of microbial oil recovery technology
In contrast, surfactants derived from plants have not received enough attention. Except for a few used in food and daily detergent industries, they have not yet been applied to the petroleum industry.

Embodiment 1

[0031] The acacia pods are crushed and dried for later use. Using 75% methanol as the extraction solvent, the total saponins were extracted by ultrasonic-assisted technology. Using oleanolic acid as a standard, the content of total saponins extracted was detected by UV spectrophotometry. The results show that when the extraction temperature is 60°C, the power is 180W, the extraction time is 30min, and the ratio of mass g to volume mL is 1:30, the highest extraction efficiency is 11.08%.

[0032] Concentrate the crude extract of total saponins and recover methanol, add water to dissolve, and use foam separation technology to preliminarily purify the total saponins of saponins. The recovery rate and purity ratio of total saponins are used as indicators to evaluate the foam separation technology. The results showed that when the feed concentration was 2g / L, the gas velocity was 1L / min, the feed height ratio was 0.8, and the pH was 6, the recovery rate of total saponins of Acacia...

Embodiment 2

[0034] Crush the acacia pods, use 75% methanol as the extracting solution to soak in a material-to-liquid ratio of 1:30, and then use microwave-assisted extraction technology to extract total saponins. In the test, oleanolic acid was used as a standard, and the content of total saponins extracted was detected by ultraviolet spectrophotometry. Under the conditions of extraction power 450W, extraction temperature 60°C, and extraction time 6min, the organic solvent extract was obtained, and the extraction rate was 5.23%. The crude extract was purified with PHD-100 macroporous adsorption resin, and the adsorption flow rate was 0.5mL / min. The volume ratio of the adsorption liquid to the resin is 1:1, and the eluent is 70% methanol solution. The eluate is concentrated and vacuum-dried to obtain light brown powdery crude saponin. Purification may increase the crude saponin content to 83.2%. The resulting extract contains saponins and other substances.

Embodiment 3

[0036] Grind the pods of acacia, pass through a 60-80 mesh sieve, and extract the total saponins of acacia in water. When the ratio of solid to liquid is 1:30, the temperature is 60℃, and the extraction time is 24h, the extraction rate of saponin is 2.31%. The obtained saponin crude extract was extracted by foam separation and purification technology and n-butanol to obtain refined saponin, and the specific experimental conditions were as described in Example 1.

Abstract

The invention relates to a total saponnis extraction technology of a honeylocust extract and an application field thereof. The total saponnis extraction technology is characterized in that the total saponnis is a plant source nonionic type surface active agent, and has the interfacial tension reduction property, emulsion activity, wetting property, temperature-resistant and salt-tolerant property, dispersant solubilizing and the like, so as to provide the applicability in the fields of recovery, storage and transportation of crude oil; the green surface active agent from the plant, namely the honeylocust, is applied to the bulk industrial purpose, so the resource utilization rate of the honeylocust is improved, the recovery rate of crude oil is improved, the storage and transportation cost of crude oil is reduced, and the pollution to the environment is reduced.

Description

technical field [0001] The invention belongs to the field of plant resource utilization, and in particular relates to a method for extracting a green nonionic surfactant and its application in the fields of crude oil recovery, crude oil storage, and crude oil transportation. Background technique [0002] Honey locust is a plant of the genus Gteditsia of the family Fabaceae. There are about 16 species in the world. They are widely distributed in central Asia, southeast Asia, and North and South America. They mainly grow on roadsides or sunny and warm places. In my country, there are 6 species and 2 varieties of acacia plants, which are excellent ecological and economical tree species, and are distributed in all provinces and regions in the north and south. Acacia pods and thorns are used in medicine, food and light industry. Acacia thorns mainly contain flavonoids, phenols, amino acids, saponins and other chemical components; acacia pods mainly contain terpenes, flavonoids, p...
