Description
Technical field
The present invention relates to crude oil or heavy crude intensifying distillation technology, be specifically related to a kind of method of crude oil or heavy crude intensifying distillation.
Background technology
At present, the crude oil heaviness increasingly of China's processing, in poor quality.The oil composition of China is compared with external oil composition, and its vacuum residuum content is higher, the vacuum residuum mass content in most oil field in crude oil up to 40%-50%.Particularly maturing field, not only output is being successively decreased, and the heaviness tendency aggravation of crude oil.In addition, crude oil in China dependence on external supply degree is higher, reaches 75%, and heaviness ratio also day by day adds sharp.Therefore, research and development crude oil, the particularly intensifying distillation techniques and methods of heavy crude, improve the deep processing of heavy oil or heavy crude, make full use of limited petroleum resources, increase the output of lightweight oil, increase economic efficiency, having become the problem that the industry of China's oil refinery is in the urgent need to address, is also the important directions of modern crude oil or the progress of heavy crude distillation technique and development.
In reinforcer strengthening crude distillation, as Russian Xin Wufa refinery to mix with heavy oil carry out underpressure distillation, its extracting rate increase by 4.3% with subtracting the refining oil of extracting out of three lines.When adding C12-C14 high fatty alcohol 4%-5% in West Siberia crude oil, the yield of light ends oil is best.China, in reinforcer, adopts as catalytically cracked oil, phenol, activator NO.3, and some composite additives etc., the extracting rate of VGO can be improved all to a certain extent.
Summary of the invention
It is gentle that the technical problem to be solved in the present invention is to provide a kind of air distillation reaction conditions, environmental protection, increase gas-liquid yield, as clear as crystal light yellow light constituent yield is remarkable, the temperature that the transition temperature of colour-change raises and pungent odour occurs can be made to delay, technique is simple, the method for crude oil easy to operate or heavy crude intensifying distillation.
Following technical scheme is adopted for solving the problems of the technologies described above the present invention:
A method for crude oil or heavy crude intensifying distillation, comprises the following steps:
<1> utilizes bio-oil to carry out pre-treatment to crude oil or heavy crude: the lower bio-oil of normal temperature and crude oil or heavy crude Homogeneous phase mixing, and the addition of bio-oil is the 0.5%-10% of crude oil or heavy crude volume;
<2> bis-pre-treatment: Cholic acids activator is added in the mixture of step <1> gained, addition is 0.01-0.05mg/ml, then thermostatically heating in water bath with thermostatic control environment;
<3> is pre-treatment again: interpolation potassium hydroxide or sodium hydroxide carry out pre-treatment again to crude oil or heavy crude, and addition is 0.01-0.05mg/g;
<4> air distillation: the mixture of the bio-oil of step <3> gained and crude oil or heavy crude, carry out air distillation.
Bio-oil in described step <1> is turps, Viscotrol C, tung oil, plam oil, soybean oil, sunflower seed oil, rapeseed oil, peanut oil or corn base bud oil.
In described step <2>, Cholic acids activator is cholic acid, Sodium cholic acid, Ursodeoxycholic Acid Tablets, ursodesoxycholic acid capsule, ursodesoxycholic acid soft capsule, Septochol, Hyodeoxycholic Acid or glycocholic acid;

Compared with prior art, the invention has the advantages that:
1, technique is simple, easy to operate;
2, the method is applied to the air distillation reaction conditions gentleness of crude oil or heavy crude, and environmental protection, gas-liquid yield increases obviously, and as clear as crystal light yellow light constituent yield is remarkable.
3, the transition temperature of colour-change increases 10 DEG C-25 DEG C, when distillation temperature rises to more than 300 DEG C, just there is minimal irritation smell out elegant, the temperature occurred than blank test pungent odour has delayed 15 DEG C-35 DEG C, simultaneously, the sound being attended by explosion occurs, illustrates that now, crude oil starts cracking;
4, in identical distillation reaction time and identical temperature of reaction interval, from collecting liquid yield, find significantly, gas-liquid yield is than only crude oil or heavy crude obviously being increased when air distillation.
