high temperature and high pressure on-line sampling device





          technical personnel and the East China Normal University Professor returned for cooperation, micro reactor design and production, high temperature and high pressure sampling device, the device and the micro reactor is connected, to realize the sampling and analysis of reactor safety in high temperature and high pressure in the reaction process, fill the blank of domestic manufacturers in the reactor analysis autoclave on-line sampling, to replace the original reactor on pressure valve to many unsafe operation sampling.

Non gaseous on-line sampling device of high voltage

high temperature on-line sampling device relates to a high temperature and high pressure gas liquid solid three-phase reaction system, the sampler is composed of sampling base, like limit rod, gasket, metal ring, gasket, cover and switching device which is arranged in a base of sampling the sampling rod, and a groove is formed, gasket, were placed in the a metal ring, gasket, outside the gland, in front of the sampling rod within the L limit sample channel, the middle part is provided with a transverse cleaning hole at the two sides of the base wall is provided with inert purge and over sampling samples leads to take over, and the inert purge gas pipe is connected with the solvent tank, the imported sample leads to take over with the end of the sample collection chamber is connected to the connecting rod and the rear end of the switching device with sampling. To understand the high pressure reaction kettle on line sampling device, please call the product engineer, welcomed the purchase of micro reactor, customized high-pressure reaction kettle, hydrogenation reactor, laboratory reactor.

Characteristics of the major compounds of sodium|Characteristics of the major compounds of sodium

of sodium peroxide

chemical formula Na2O2, light yellow powder, density 2.805g/cm3. It has strong oxidation, in the molten state encountered cotton, carbon powder, aluminum powder and other reducing substances will explode. Therefore, should pay attention to the safety of storage, can not contact with flammable materials. It is easy to absorb moisture, in case of water or CO2 will react to generate oxygen. It is insoluble in ethanol, and carbon dioxide in the air and release oxygen, commonly used in the absence of air situation, such as mines, tunnels, diving, spacecraft and so on, will further change people exhaled carbon dioxide to oxygen, for people to breathe in. Sodium peroxide is commonly used in industry as a bleaching agent, disinfectant, disinfectant, deodorant, oxidant etc.. Usually in dry air free of carbon dioxide in the flow of sodium metal is heated to 300 DEG C to produce sodium peroxide. Because it is easy to deliquescence, easy and carbon dioxide reaction, must be stored in sealed containers.

sodium chloride

commonly known as salt, is a colorless cubic crystal or white crystal. Density 2.165g/cm3. Melting point 801. Boiling point 1413. Soluble in water, glycerin, slightly soluble in ethanol, ammonia. Insoluble in hydrochloric acid. The slight deliquescence in the air. By the sea water (containing an average of 2.4% sodium chloride) introduced by sun drying, salt, concentration and crystallization, prepared crude. It will be water, steam heating, sand filter, concentrated by ion exchange membrane electrodialysis, get salt (sodium chloride containing 160 ~ 180g/L) by evaporation precipitation of bittern gypsum, centrifugal separation, preparation of sodium chloride 95% (2% moisture) after drying can be made of salt (table  salt). Can also be used as raw materials, salt Saline Lake brine, after sun drying, preparation of crude salt. Underground brine and salt as raw material, through three or four effect evaporation, crystallization, centrifugal separation system. Used in the manufacture of soda and caustic soda and other chemical products, ore smelting. Food industry and fisheries for salt, but also can be used as raw materials and refined salt seasoning salt.

sodium hydroxide

commonly known as caustic soda, caustic soda, caustic soda, caustic soda. Pure anhydrous sodium hydroxide is white, translucent, crystalline solid. Sodium hydroxide is very soluble in water, the solubility increases with the increase of temperature, the dissolution can release a lot of heat, 288K its saturated solution concentration of up to 26.4mol/L (1:1). Its water solution is astringent and soapy, in alkaline solution, with all the characteristics of alkali. Commercially available caustic soda has two kinds: solid and liquid: pure solid caustic soda is white, there are massive, flake, stick, granular, brittle; pure liquid caustic soda is colorless transparent liquid. Sodium hydroxide is easily soluble in ethanol and glycerol; but insoluble in ether, acetone, ammonia. To the fiber, the skin, the glass, the ceramics and so on has the corrosion function, the solution or the concentrated solution dilution can release the heat

Characteristics of hydrogenation reactor|Characteristics of hydrogenation reactor

micro type high pressure hydrogenation reactor, hydrogenation high pressure reactor , catalytic reactor, magnetic stirring autoclave, autoclave

parallel reaction

hydrogenation reactor is mainly used for the hydrogenation reaction, the major difference is the reaction of hydrogen is flammable and explosive gas, to prevent the leakage of hydrogen producing reactor explosion and fire, so the electrical parts are used in hydrogenation reactor explosion, such as motor selection of explosion-proof motor, heater with explosion-proof heating, temperature sensor and pressure sensor are selected explosion proof, to prevent sparks.

hydrogenation is a chemical unit process, is an organic matter and hydrogen from the reaction process, due to the hydrogen is not active, usually must have the presence of the catalyst to react. But the reaction between inorganic and hydrogen, such as nitrogen and hydrogen to produce ammonia, carbon monoxide and hydrogen to react to produce methanol in the chemical process is not called hydrogenation, and called "synthesis"".


hydrogenation in chemical production is generally divided into two kinds:  

Hydrogenation of

  –  simply increase the number of hydrogen atoms in organic compounds, organic matter into unsaturated organic saturated, such as hydrogenation of benzene to cyclohexane used in the manufacture of nylon; fish oil hydrogenation produced oil for hardening solid and storage and transportation; manufacturing process, is also a glycerin soap a hydrogenation process.


hydrogen solution –    simultaneously the organic molecule is broken and the hydrogen atom is added. If the coal or heavy oil through the hydrogen solution, into a small molecule liquid state of artificial petroleum, can be obtained by fractionation of synthetic gasoline.
