EOR surfactant preparation

Because EOR surfactant and additives are anionic sulfonate and Briquette machine, its enhanced oil recovery is most significant, so here focuses on EOR important anionic sulfonate and carboxylate synthesis and preparation. Sulfonation of the salt used in preparation of the sulfonating agent, concentrated sulfuric acid are used? Oleum? Trioxide and chlorosulfonic acid. For oil expeller industrial production, comprehensive comparisons to sulfur trioxide sulfonation process optimization, its versatility? Security? Applicability are better and lower cost. So sulfonate synthesis industry gained wide application and development.

Preparation of EOR petroleum sulfonate

Petroleum sulfonate is a crude oil or fractions rich sulfonated aromatic product obtained aromatic compounds whose main component is a single salt, which has an aromatic ring with one or several five-membered ring fused together, there are two aromatic ring with one or more five-membered ring fused together, compared to the rest of aliphatic hydrocarbons and oil equipment hydrocarbons sulfonated or oxide. Currently the main use sulfonation, there were three kinds of preparation: white oil production byproduct France? Sulfonated crude sulfonation method and the two-step method. (1) white oil production by-products method. In the production of white oil refining using sulfonation process, removal of aromatic hydrocarbons in the feedstock oil and other active ingredients, is the main product is a mineral oil and machine for pellets, in the water phase is mainly petroleum sulfonate. Such petroleum sulfonate average relative molecular mass between 400 and 580 for over sulfonate. Flooding EOR used as a surfactant required, the need for a certain degree of modification. (2) crude sulfonation. Generally having a boiling point of 210 ~ 500 ℃ reduction in second distillate as a raw material, the direct use of sulfur trioxide or fuming sulfuric acid sulfonation, and then the obtained alkali alkyl aryl sulphonates. The method of using the raw oil refining production petroleum sulfonate, its treatment process for the heavy - Distillation - hydrogenation - furfural refining - sulfonated - and in other procedures. The petroleum sulfonate prepared sulfonated crude product performance with different nature are very different. High aromatic content naphthenic crude oil, petroleum sulfonate production byproducts less easy to obtain with the formation of ultra-low interfacial tension of oil products; while paraffin base Pellet mill aromatics content, the production of by-products of petroleum sulfonate up to 60% , high production costs, in terms of economic and process by-products is limited. (3) two-step sulfonation. First, the Act of crude oil in the catalyst reacts with SO2 and Cl2, the crude oil alkane sulfonyl chloride generated, then SO3 sulfonation of aromatic hydrocarbons in the crude oil to generate sulfonated aryl sulfonates, obtained by NaOH. alkyl sulfonates and aryl sulfonates. Advantage is that the entire fraction can generate oil sulfonates, sulfonated integrated conversion rate of 70% or more, reducing by-products, reducing costs. Petroleum sulfonates prepared above three method of standard products concentrate active matter content is generally 60% to 63%, about 35% of saturated hydrocarbons, about 2% to 5% moisture content. But it can be made up to 80% active matter content, and as 30% of the products used directly.

Granularity requires minimal silicon oil refinery

Mainly suitable for grinding particles of silicon metal processing industry in the material particles and silicon metal in the domestic processing industry is mainly used in disposable equipment jaw crusher , feed equipment , roller crusher, Lei Ying mill working principle of the traditional equipment , the main way of using impact extrusion crushing materials , because the particle size of silicon metal minimal requirements , so the traditional proverb machining , it requires repeated processing, repeated screening , the number of extra flour yield is higher, This leads to high processing power consumption of silicon metal industry to create a lot of waste, because silicon metal pellet mill machine all precious materials , and the first production of the first processing level of efficiency of the enterprise will cause considerable benefits or losses , our silicon metal for the enormous waste of resources .

oil extraction nutrients out

Oil nutrients single soybean salad oil . Salad oil is also commonly used cooking oil, experts, salad , also known as " one oil" ( the new national standards ) , the manufacturer of soybean oil to remove special beany through eight procedures refined soybean oil , so that it becomes colorless, odorless oil types . So many of soybean oil itself nutrients inevitably be " refined out " , and crude oil production  favorite " Bean " taste is gone.
Judging from the nutritional value of soybean oil fatty acid composition is better, it is rich in polyunsaturated fatty acids , have the effect of preventing cardiovascular disease , but also contains large pellet mill machine of vitamin E, vitamin D, and rich in lecithin, both to human health beneficial . Meanwhile, experts also stressed soybean salad oil types are not the flavor , not as good as the quality of edible sesame oil , sunflower oil, peanut oil, soybean salad oil and because of the high saturated fatty acids , but also requires other kinds of edible oil .
