What is the process of absorbing ammonia from coal gas in the production of Fersom anhydrous? 5

1) Increasing the concentration, increasing the temperature, etc., can increase the reaction rate, reduce the reaction rate under decompression, reduce the concentration of products, and reduce the reaction rate, so the answer is: BC; (2) Ammonia, water and carbon dioxide can react to form ammonium carbonate or ammonium bicarbonate, and the equation is 2NH3+CO2+H2O=(NH4)2CO3, (NH4)2CO3+CO2+H2O=2NH4HCO3, so the answer is: 2NH3+CO2+H2O=(NH4)2CO3, (NH4)2CO3+CO2+H2O=2NH4HCO3; (3) The positive reaction is exothermic, the copper liquid absorbs CO, and the equilibrium should be moved to the positive direction, then the CO can be absorbed under low temperature pressure, and then the copper washing solution can be transferred to another container, and the CO is released at high temperature and low pressure, and then the copper washing solution is recycled, so the answer is:

Absorb CO under low temperature pressure, then transfer the copper wash to another container, release CO at high temperature and low pressure, and then recycle the copper wash; (4) Among the constituent elements of molten copper, the short-period elements include H, C, N, O and other elements, the atomic radius of h is the smallest, and the atomic radius of the same periodic element gradually decreases from left to right, then the atomic radius c n o h, and the orbital expression of the outermost electron configuration of the nitrogen atom is; Comparing the strength of non-metallic properties, according to the stability of hydrides, the answer is: c n o h;; stability of NH3 and PH3; (5) The electronic formula of CS2 is similar to CO2, the electronic formula is, both are molecular crystals, the larger the relative molecular mass, the greater the intermolecular force, the higher the melting point, so the answer is: ; Both are molecular crystals, and the greater the relative molecular mass, the greater the intermolecular forces

Water gas is a mixture, a mixture of carbon monoxide and hydrogen, which is produced by coal and water at high temperatures, hence the name: C+H2O=CO+H2.

Water gas: Water gas, a kind of low calorific value gas, the main components are hydrogen and carbon monoxide, mainly used as raw materials for synthetic ammonia, synthetic liquid fuels, etc., with trace amounts of CO, HC and NOx. The combustion rate is twice that of gasoline, the anti-knock performance is good, and the compression ratio can be reached according to foreign research and patent reports.

The thermal efficiency is increased by 20 to 40%, the power is increased by 15%, the fuel consumption is reduced by 30%, and the exhaust gas purification is close to the European IV standard, and a trace amount of platinum catalyst can be used for purification. Simplify manufacturing and reduce equipment compared to alcohols and ethers, with lower costs and investments. Compression or liquefaction is similar to hydrogen, but it does not need to remove CO, and the investment in building a station is low.

The reduced costs and investments can also be partially compensated for by compression (and alcohol ether compression) or liquefaction. It is toxic, used as a fuel in industry, and a chemical raw material.

Generally speaking, it depends on the type of work, and in most cases it is about a month.

A workshop dedicated to arranging internships.

It is NH3, which is more anhydrous than ammonia in any solid, liquid or gaseous state.

NH3 is easily soluble in water to form NH4 (OH), also known as ammonia, which is alkaline.

It is different from ammonia, so it is prominently called anhydrous ammonia.

1.Process route: The common process of generating synthetic ammonia from anthracite as raw material is:

Gas production -> semi-aqueous gas desulfurization -> compressor 1,2 sections -> shift -> shift gas desulfurization -> compressor 3 stages -> desulfurization -> compressor 4,5 sections -> copper washing -> compressor 6 stages -> ammonia synthesis -> product NH3 Methanation method is used to desulfurize and remove CO in the feed gasCO2,.

After purifying the water gas, and then making it and water vapor together with the catalyst to convert the CO into CO2 (CO+H2O, CO2+H2), the hydrogen content can be obtained with a hydrogen content of more than 80%, and then pressed into the water to dissolve the CO2, and then through the ammonia-containing cuprous formoate (or cuprous acetate-containing ammonia) solution to remove the residual CO to obtain purer hydrogen, and then react with nitrogen to synthesize ammonia.

According to the flow chart of the coke oven body and the drum cooling system, a large amount of waste gas from the coke oven has been condensed into a liquid before entering, and at the same time, the coal entrained in the gas.

Dust, coke powder is also collected, and the water-soluble components of the gas are also dissolved in the ammonia. Tar, ammonia, and dust and tar residue flow into the mechanized tar ammonia separation tank. After separation, the ammonia water is recycled, the tar is sent to the centralized processing, and the tar residue can be redistributed into the coal, and the coking gas enters the primary cooler to be directly cooled or indirectly cooled to room temperature, at this time, the residual water and tar in the gas are further removed.

The gas after the initial cooler is mechanically tar trapped, so that the tar mist suspended in the gas is removed by mechanical means, and then enters the blower to be pressurized to about 19,600 Pa (2,000 mm water column). In order not to affect the operation of gas refining in the future, such as ammonium sulfate coloring, desulfurization liquid aging, etc., the gas is passed through the electric tar precipitator to remove the residual tar mist. In order to prevent naphthalene from crystallizing and precipitating from the gas at low temperature, a naphthalene washing tower is set up before the gas enters the desulfurization tower for oil washing and absorption of naphthalene.

Hydrogen sulfide in the gas is absorbed with a desulfurizer in the scrubber, and at the same time, hydrogen cyanide in the gas is also absorbed. The ammonia in the gas is absorbed by water or aqueous solution in the ammonia suction tower to produce liquid ammonia or ammonium sulfate. When the gas passes through the ammonia absorption tower, because the reaction of sulfuric acid to absorb ammonia is an exothermic reaction, the temperature of the gas rises, in order not to affect the operation of crude benzene, the gas enters the benzene washing tower after being cooled by the final cooling tower, and the benzene, toluene, xylene and cyclopentadiene and other low-boiling hydrogen carbides and high-boiling substances such as styrene and nagumarone are absorbed by washing oil, and at the same time, organic sulfides are also removed.
