EOR oil carboxylate Preparation

Carboxylate by petroleum oil fractions by high temperature oxidation, and then by saponification? Extraction of the product obtained. It belongs to the oxidative cleavage product saturated hydrocarbon complex composition mainly containing an alkyl carboxylate salts and aryl carboxylate salts. Production of oil carboxylate main raw material for regular oil expeller and second-line fraction to vapor phase or liquid phase oxidation oxide production. Vapor phase oxidation process with oxygen in the air as oxidant at 325 ℃, oleic acid cadmium oxide as a catalyst, the oxygen / hydrocarbon ratio of 2.20, the water / hydrocarbon ratio of 25 to 50. After the reaction product was saponified with NaOH to remove the oil phase, to obtain petroleum products carboxylate, effective content was 10%. Liquid phase oxidation in the vapor phase oxidation process is a process based on a new method developed by liquid oxidizing agent to conduct the reaction at 180 ℃, the machine for pellets of carboxylate may be raised to 20%. Oil is an important carboxylate cosurfactant, together with synthetic alkylbenzene sulfonates, can increase the stability of the surfactant system? Dilution resistance and compatibility with a base.

How to improve the oil yield oil processing

Before using the press, first of all should be ready aids and containers , check and adjust the belt tightness . Then start the motor , the machine empty running around 15min, check the speed of the pressing screw shaft. Average speed should be around 33dmin. Do you want to pay attention to when idling gear box gear meshing and sound normal, whether nmb oil equipment and motor parts properly. When press idling , the motor current should be about 3A. If the current is too high , you should immediately stop checks, adjustments and then boot.

After the load is normal, around 50kg ready rapeseed or soy , ready to put into the hopper . Note: When you start squeezing feed not too fast, otherwise the sudden increase in pressure within the bore virgin , virgin not turn the screw shaft , causing blockage virgin bore , even to squeeze cage rupture, a major accident . So at the beginning of the compression , the seed oil press be evenly slowly into the hopper , so press be run together . So repeatedly , sustained more than 3 ~ 4h , so press the temperature gradually increased , and even take smoke ( this is normal ) . At the start of the press virgin bore low temperature, can be slowly twist the handle on the withered section stud , increase the thickness of the cake , while improving water into juice billet , to be squeezed bore temperature. Rose to about 90 ℃, the normal operation of the press , the cake thickness can be adjusted to 1.5 ~ 2.5mm, and tighten the nut tightened.

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.

crude oil processing qualification

Local refineries in Shandong largest refining capacity is higher, as in refining the strongest provinces. Although Shandong to refining qualified , but subject to import quotas simply could not get enough crude oil for processing, the high price of fuel oil purchases only alternative .  Oil machine  are currently more than 40 Shandong into the scale of local refineries , but the data show that in 2011 its first crude oil distillation capacity utilization average of only 35% , the reason is a serious lack of raw materials. The face of private enterprises to enter the oil market high threshold phenomenon , breaking the upstream crude oil is the primary bottleneck issue.
In recent years, a number of parts on the new line with national industrial policy to fine chemicals mainly petrochemical refinery processing enterprises. Through continuous development and growth of these enterprises in the enterprise scale, devices, and technology management , etc.,  oil processings  to the national level of the new era of advanced refining companies , have been with the fine chemical production and oil production capacity. However, crude oil processing qualifications, straighten the country no longer small oil refineries after approval, but some state-owned enterprises due to the petrochemical venture participation , but also enjoy the crude oil distribution plan . This has resulted in similar enterprises can not enjoy the same policy treatment , resulting in unfair competition , resulting in no oil distribution plan new enterprises in the " cracks " in the tough survive and costly operation .

whereabouts of imported crude oil

Adhere to quality audit and quota management on the grounds that an increase in the international oil market, China 's right to speak, does not cause the blind bidding competition among enterprises , avoiding crude oil into less demanding energy saving small refinery . But it also  pellet machine  phenomenon, namely crude oil imports through state trading and non- state trading of control , the three major oil firms firmly grasp the domestic oil market.
A private oil company sources said the relevant national policies on imported crude oil whereabouts are strictly limited, non-state trading of crude oil imports in principle, only in three refineries processing  oil processings  , which imported crude oil prices must first obtain three refinery row production orders. This series of provisions constituted blocking private capital into the oil field invisible threshold.
Zhuo record information on oil analyst Gao Jian , told reporters that local refineries have been through various channels to require the State to release crude oil imports qualification management , increase oil import quotas .
