Abstract
The invention discloses a joint production process of synthesis ammonia and methanol employing coke oven gas and blast furnace gas. The joint production process is characterized in that after separating methane and high-carbon material in the coke oven gas, the coke oven gas is mixed with blast furnace gas according to a certain percentage to be used for the joint production of synthesis ammonia and methanol. The cost of the prepared liquid ammonia and methanol is lower than that of ammonia and methanol prepared from common coal.
Description
One, technical field
The present invention relates to chemical field, is a kind of method of effectively utilizing process gas to be used to produce synthetic ammonia and methyl alcohol.
Two, background technology
For the technology that coke(oven)gas is produced methyl alcohol, the method for usually using is utilized carbon monoxide and hydrogen synthesizing methanol then for methane conversion is hydrogen and carbon monoxide.Because production technique decision, hydrogen are seriously superfluous, must be used for other products productions to hydrogen or be used for generating, just can make this technology give full play to its economic benefit.Yet Methane Conversion needs huge equipment and more operation energy consumption, so cause miniaturization industry to be promoted because of investing the too huge difficulty that compares, can only use in large-scale coking system.
For the technology that blast furnace gas gas is produced liquefied ammonia, the usual method of using is utilized nitrogen and hydrogen synthetic ammonia in the blast furnace gas then for carbon monoxide being converted into hydrogen and carbonic acid gas.Because the production technique decision, the hydrogen wretched insufficiency must separate nitrogen from blast furnace gas, just can make this technology performance economic benefit.Yet equipment that the nitrogen separation process need is huge and more operation energy consumption so cause miniaturization industry to be promoted because of investing the too huge difficulty that compares, can only be mixed in the part blast furnace gas in the coal Ammonia Process.
Three, summary of the invention
For better reclaim effective constituent hydrogen in the coke(oven)gas and and blast furnace gas in carbon monoxide and nitrogen, the present invention utilizes the strategy of combination producing, is used for improving gas effciency.
Methane and high carbon species are the rare gas elementes of ammonia, two building-up reactionss of methyl alcohol.In order to reduce energy consumption, at first need to separate methane and high carbon species in the coke(oven)gas.
With the coke(oven)gas behind separation of methane and the high carbon species, mix according to a certain percentage with blast furnace gas, can be at synthesizing methanol under 4.0～12.0MPa, and the gas behind the synthesizing methanol, behind pure hydrocarbonylation removal of carbon monoxide, carbonic acid gas, synthetic ammonia under 12.0～32.0MPa.
By this technology, can the hydrogen in the coke(oven)gas be made full use of, and carbon monoxide in the blast furnace gas gas and nitrogen also can be fully used.
Technology of the present invention and traditional ammonia join the pure technology following characteristics of comparing:
Do not have the gas maked coal system: this process is that coal is become hydrogen and carbon monoxide.
Do not have the carbon monodixe conversion system: this system becomes hydrogen to carbon monoxide.
Technology of the present invention and the coke(oven)gas manufacture order alcohol technology following characteristics of comparing:
Do not have methane conversion and coal-burning boiler system, methane and high carbon species become urban safety coal gas by gas delivery.
Do not have the hydrogen waste, methyl alcohol synthetic remaining hydrogen is used for ammonia synthesis.

| ??(V％) | ??0.5 | ?68 | ??2 | ??0.5 | ??28 | ??2 |
Two kinds of gases were mixed according to 1000: 158, just can realize alcohol: ammonia=1: 0.83 production capacity.
This patent reclaims methane, hydrogen device through actual the use at coke(oven)gas, and effect is fairly obvious, effectively reduces the energy consumption in the gas recovery process, has saved cost.
