Embodiment 1
[0073] This embodiment provides a saponin plant extract, which is prepared through the following steps:
[0074] First select 100 g of saponin bark (the remaining skin after the saponin pod is removed from the fruit), and grind the saponin bark into powder by using a pulverizer to obtain saponin powder;
[0075] Inject the saponins powder into a Soxhlet extractor, add 600g of absolute ethanol to extract for 3 hours, and obtain a mixed solution;
[0076] The mixed solution was suction-filtered using a Buchner funnel, and the filtrate was distilled under reduced pressure using a rotary evaporator until solids were precipitated. The concentrated solution obtained at this time was a saturated solution (brown liquid), that is, a saponin plant extract.
[0077] It is determined that in the saponin plant extract extracted in this embodiment, the total saponin content is 21% of the saponin bark mass, and the saponin effective concentration in the saponin plant extract is 19%.
Embodiment 2
[0079] This embodiment provides a saponin plant extract, which is prepared through the following steps:
[0080] Select 100g of licorice and grind it into powder with a mortar to obtain licorice powder;
[0081] Pour the licorice powder into the flask, add 300g of water to leaching at 70°C for 4 hours, use a Buchner funnel to carry out suction filtration, and filter the residue again with 300g of water to leaching for 4 hours, suction filtration, repeated leaching and suction Filter four times to obtain the mixed solution, which is the sum of the liquid obtained by leaching for four times;
[0082] filtering the mixed solution, concentrating the filtrate and evaporating the water therein to dryness by vacuum distillation to obtain a solid saponin plant extract;
[0083] The above-mentioned solid is dissolved in absolute ethanol and then concentrated until solid is precipitated, and the concentrated solution at this time is the saponin plant extract.
[0084] It has been dete...
Embodiment 3
[0086] This embodiment provides a saponin-containing composite hydrate antipolymerization agent, which is prepared through the following steps:
[0087] The saponin plant extract extracted in Example 1 and the auxiliary antipolymerization agent Span20 were mixed according to a mass ratio of 3:1, and stirred evenly to obtain a composite hydrate antipolymerization agent containing saponin.
[0088] A visible transparent sapphire high-pressure reactor and supporting system were used to conduct a hydrate form test on the anti-polymerization effect of the above-mentioned saponin-containing composite hydrate anti-polymerization agent provided in this example. Among them, the oil-water emulsion of the oil-gas-water mixed transportation system is prepared from 0.5mL deionized water and 9.5mL diesel oil, that is, the volume content of water in the oil-gas-water mixed transportation system is 5% (based on water and The sum of the volumes of the oil is the basis for calculation), the tot...
