Abstract
The invention discloses a kind of production methods of petroleum sulfonate, and this approach includes the following steps:After sulfonation, using the solvent insoluble in petroleum component as extractant, stratification after being extracted to sulfonation acid-soluble oil, upper layer is that raffinate oil returns to continuation sulfonation, is repeated the above process, until the arene content in raw material is dropped to 5% or less, lower layer is the extractant containing sulfonic acid, extractant is steamed by distillation, sulfonate can further be prepared by obtaining sulfonic acid, and the extractant steamed is recycled.This method is using the solvent insoluble in petroleum component as extractant, sulfonation acid-soluble oil is extracted, sulfonic acid after extraction and separation is directly neutralized into sulfonate, raffinate oil, which returns, continues sulfonation, because being free of sulfonic acid in raffinate oil, when being contacted again with sulfonating agent, would not acid sludge be become by sulfonation again, to achieve the purpose that improve sulfonate yield.
Description
Technical field
The present invention relates to sulfonate production fields, more specifically to a kind of production method of petroleum sulfonate.
Background technology
Petroleum sulfonate is a kind of widely used anion surfactant, is played in agent for improving oilfield recovery etc.
Important role.
Petroleum component is complicated mixture, is had a very wide distribution, containing a large amount of gum asphalt and polycyclic aromatic hydrocarbon etc.,
Contained aromatic hydrocarbons is because of structure difference sulfonation process and asynchronous, and with the progress of sulfonating reaction, the aromatic hydrocarbons of sulfonation at first is particularly easy to
Further sulfonation is more sulfonic acid, to influence the product quality of sulfonate, reduces the yield of petroleum sulfonate and generates to environment
The acid sludge of pollution.
To avoid the sulfonation excessively of sample, existing processing method from being roughly divided into two classes:The first kind passes through the improvement to equipment
Reduce the generation of acid sludge, as CN00240550, CN85109591, CN96107060, CN200510093638,
CN200520118134, CN200610028680, CN200610102153, CN201210262133, CN201320359754 etc.,
These methods are only capable of reducing the production quantity of acid sludge on a small quantity, are influenced on the raising of petroleum sulfonate yield limited.Second class is added molten
The method that dilution agent feedstock oil reduces acid sludge, CN201210384390 disclose a kind of by residual oil progress sulfonation preparation oil field sulphur
The method of Barbiturates surfactant proposes to avoid crossing sulfonation problem in residual oil sulfonation process first by residual oil and solvent
In mass ratio 1: 2~5 dilutions, then cool down, and after sulfonating agent is diluted with solvent in mass ratio 1: 1~3, take opposite residual oil addition
1/2~1/20 complexing agent be added residual oil in, 0.5~2h of aging, after being then gradually added into the dilution of 1~3 times of residual oil quality
Sulfonating agent is added alkali and is neutralized, and sedimentation removing bottom aqueous solution is distilled off solvent, petroleum sulfonate production finally can be obtained
Product.CN201210235703 is disclosed with SO3It is solvent, at a lower temperature sulfonation as sulfonating agent, aprotic alkyl halide
The method for preparing sulfonated humic acid.CN201010271259 and CN201310660630 discloses a kind of petroleum sulfonate surface
The preparation method of activating agent, this method are the crude oil fractions oil using 350~500 DEG C as raw material, with 60~120 DEG C of solvent naphthas, chlorine
It is diluent for aromatic hydrocarbons or chloralkane, using the sulfur trioxide of gas phase as sulfonating agent, and uses falling film reactor, pass through control
Purpose product is made in reaction temperature, aging temperature.CN 201210094872 discloses a kind of tapped oil alkylate sulfonation legal system
The method of standby surfactant, using catalytic cracked oil pulp or the alkylate of recycle oil tapped oil as raw material, with the concentrated sulfuric acid, hair
Cigarette sulfuric acid or SO3It carries out sulfonating reaction using petroleum ether, dichloroethanes, nitrobenzene as solvent for sulfonating agent and prepares sulfonate type table
Face activating agent.Although these above-mentioned methods make sulfonating conditions mitigate, but the acid sludge generated is present in dissolved state in acid-soluble oil,
The quality of sulfonate is affected, in addition, solvent such as halogenated hydrocarbons being added etc. not only damages greatly human body, atmospheric environment is destroyed tight
Weight will also cause the chloride ion corrosion during oil refining working process of downstream after being remained in oil.
Therefore, acid sludge yield is greatly lowered in exploitation one kind, and the method for sulfonating for improving aromatic hydrocarbons utilization rate in oil very must
It wants.
