Embodiment 1
[0022] A crude oil pour point depressant, which is composed of "mixed methyl naphthalene" and ethylene glycol butyl ether.
[0023] The added ethylene glycol butyraldehyde should be able to ensure that the said pour point depressant is always liquid in an environment lower than the melting point of commercial "mixed methylnaphthalene" -5°C, without producing crystals, solids or solidification. In order to achieve the aforementioned As a goal, those of ordinary skill in the art can determine the minimum concentration of the added special organic solvent in the described pour point depressant through existing methods.
Embodiment 2
[0025] A crude oil pour point depressant, which is composed of "mixed methyl naphthalene" and diethylene glycol butyl ether.
[0026] The diethylene glycol butyl ether added should be able to ensure that the said pour point depressant is always liquid in an environment lower than the melting point of the commercial "mixed methylnaphthalene" -5°C, without producing crystals, solids or solidification. In order to achieve For the foregoing objectives, those skilled in the art can determine the minimum concentration of the added special organic solvent in the pour point depressant through existing methods.
Embodiment 3
[0028] The added diethylene glycol ether should be able to ensure that the pour point depressant is always liquid in an environment lower than the melting point of commercial "mixed methylnaphthalene" -5°C, without producing crystals, solids or solidification. In order to achieve the aforementioned goals, those of ordinary skill in the art can determine the minimum concentration of the added special organic solvent in the pour point depressant through existing methods.
