Problems solved by technology

Even if the polycyclic aromatic hydrocarbons developed by these two processes can meet the requirements of the European Union, due to the low content of aromatics and poor compatibility with rubber, they cannot be used as substitutes for rubber filler oils

Embodiment 1

[0021] A production method of an environment-friendly rubber filler oil, the specific steps are: using the difference in specific gravity between the raw material oil and the solvent to carry out extraction in countercurrent full contact in the extraction tower, dissolving the polycyclic aromatic hydrocarbons in the raw material oil into the solvent, and It automatically settles to the bottom area of ​​the tower, and the extracted raw material oil automatically rises to the top of the tower, and the solvent is recovered through the stripping process, and the entrained solvent is removed, which is the environmentally friendly rubber filler oil; the detailed process flow of the present invention is as follows:

[0022] See attached figure 1 , the raw oil enters the raw oil degassing tower (T2101) through heat exchange for vacuum stripping and degassing. The degassed raw material oil at the bottom of the degassing tower is pumped out by the pump P2102 at the bottom of the degassi...

Abstract

The invention relates to a method for producing environment-friendly rubber filling oil, which comprises the following steps: performing extraction through back flow and sufficient contact in an extraction tower by using the specific gravity difference of raw oil and a solvent; dissolving polycyclic aromatic hydrocarbon in the raw oil into the solvent, and depositing the polycyclic aromatic hydrocarbon to the bottom area of the tower automatically; raising the raw oil after the extraction to the top of the tower automatically; performing solvent recovery through a steam stripping process; and removing the carried solvent to obtain the environment-friendly rubber filling oil. The method has the advantages that the environmental protection of an oil product meets European Union requirements, the oil product has good compatibility with rubber, and the adopted solvent recovery process has the advantages of high solvent recovery rate, easily achieved conditions and the like.

Description

【Technical field】 [0001] The invention relates to the technical field of petroleum, in particular to a production method of environment-friendly rubber filler oil. 【Background technique】 [0002] In the rubber production process, in order to improve the elasticity, flexibility and processing performance of rubber materials, it is usually necessary to add specific rubber filler oil. However, polycyclic aromatic hydrocarbons (PCA) such as anthracene and phenanthrene contained in rubber filler oil have been classified as carcinogenic CMR substances by the European Union. The annex to REACH regulations has made clear and strict regulations on the content of PCA in products, and PCA in extender oil is less than 3%. [0003] The research and development of many alternative rubber filler oils has been carried out successively, such as related patents CN1637054 and CN1397417. Chinese Patent Publication No. CN1637054 discloses an oil-extended rubber and a composition containing low...
