Preparation method for nanoscale base material of crude oil pourpoint depressant

Abstract

The invention discloses a preparation method for a nanoscale base material of a crude oil pourpoint depressant and belongs to a crude oil pourpoint depressant and the technical field of the crude oil pourpoint depressant. In the method, a thermal weight loss test, a crystallization property test, an X-ray diffraction test, a powder particle size test, a water content test and a viscosity test in which a compounding agent formed by the nanoscale base material of the crude oil pourpoint depressant is added into the crude oil are adopted, wherein polar groups are grafted to the surfaces of inorganic nanoparticles; when results of the thermal weight loss test, the crystallization property test, the X-ray diffraction test, the powder particle size test and the water content test are considered to be qualified, the nanoscale base material of the crude oil pourpoint depressant is considered to be qualified. As the nanoscale base material of the crude oil pourpoint depressant is considered to be qualified by testing, the self-aggregation easily generated by the nanoscale base material of the crude oil pourpoint depressant is limited; the originally owned performance can be fully played.

Description

technical field [0001] The invention relates to the technical field of crude oil pour point depressant, in particular to a preparation method of nanoscale base material of crude oil pour point depressant. Background technique [0002] As the country pays more and more attention to energy saving, safety, environmental protection and strategic reserves, the energy saving and safe flow of oil and gas transmission medium in pipelines is more important than ever for pipeline operations. At present, most of the crude oil produced in my country has high wax content and poor fluidity at low temperatures. In order to solve this technical problem, my country’s crude oil is usually transported by heating. This method not only consumes a lot of fuel oil and power, but also After the pipeline is shut down, there is great insecurity in restarting the pipeline. In order to solve this problem, a crude oil pour point depressant nano-scale substrate for pour point and viscosity reduction of h...

Problems solved by technology

At present, most of the crude oil produced in my country has high wax content and poor fluidity at low temperatures. In order to solve this technical problem, my country’s crude oil is usually transported by heating. This method not only consumes a lot of fuel oil and power, but also After the pipeline stops, the restart of the pipeline is very unsafe

In order to solve this problem, a crude oil pour point depressant nano-scale substrate for pour point and viscosity reduction of highly waxy crude oil has been developed. The nano-effect of the nano-scale substrate is related to its high surface activity and large specific surface area. However, the nano-scale substrate of crude oil pour point depressant is prone to self-agglomeration, making it difficult to fully exert its original performance.
