Physical method extraction technology

 Physical methods include a variety of methods extraction technology. Former Soviet Union first proposed artificial earthquakes, oil refinery gas fracturing and ultrasonic methods. United States, Canada for some heavy heating method using electromagnetic waves. China since the 1980s, since the basis oil equipment from abroad, has launched a variety of physical methods of oil recovery methods and field trials, and some development of technology has begun to take shape.

Microbial enhanced oil recovery technology

Microbial enhanced Oil processing is abroad in the 1980s developed a stimulation, has more than 100 oil fields in the world were tested, but not yet formed a large-scale application. Microbial enhanced oil recovery in two ways, one in oil injected microorganisms, for single-well stimulation; two injection wells is injected directly into the micro-organisms, with the injection of water reservoir for flooding. China has in Jilin, Food dehydrator, Xinjiang, Daqing oilfields for industrial application of microbial enhanced oil recovery site, have achieved good initial results.

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 Food dehydrator, 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 machine for pellets. 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 crude oil 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.

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.

oil processing principle structure

 When press operation , after a good deal of oil squeezed from the hopper into the breech . Pressed by the screw to keep the embryo transfer so that the material in advance , be pressed . As the material of the embryo in the press virgin bore in the state of motion oil extraction out under conditions of high pressure pressing chamber , producing a great deal of friction between the embryo and the virgin material snails, embryos and virgin material breech , so friction can cause relative movement between the micro- parison material . On the other hand , due to the pressing screw root diameter is gradually thickening Park pitch is gradually reduced , so when pressing screw rotation , screw hard material embryos that can move forward , but also outward and upward while pressing screw thread close as the surface of the material layer is also pressed axis. Such virgin bore in each embryo particulate material , such as the speed is not the same direction, but also exist between the relative motion of particles . The heat generated by friction and the oilfield equipment process operation to meet the necessary heat helps to promote the parison thermal denaturation of proteins , destruction of the gel, to increase the ductility , while also reducing some of the oil to the viscosity tends to be precipitated , thus improved oil yield oil press , so there is oil squeezed out feed and discharge gap and the gap outflow of exhaust from the park.

Hydraulic press Steps

Hydraulic press Step one : First of all aids should be ready and containers , check and adjust the belt tightness . Then start the motor , the machine empty running around 15min, oil extraction  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 the seed oil extraction 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.
