CO generator process! !

Are the equipment and processes of this CO generator furnace the same as those of ordinary gas generation furnaces? (It belongs to pure oxygen continuous gasification; similar to oxygen-enriched continuous gasification, the equipment requires appropriate modifications.) Are there also various stages such as blowing, top blowing, bottom blowing, double top blowing, and cleaning? (No blowing, downward blowing, two upward blows, and cleaning stages – only internal blowing and upward blowing.) Is the same vaporization furnace used? (Just like fixed-bed gas generators, gasification furnaces also require appropriate modifications; they have a high height-to-diameter ratio and a relatively high carbon layer inside the furnace.) Additionally, what processes and equipment are commonly used for producing pure oxygen through air separation? (Generally, the cryogenic method is used; it is necessary to consider factors such as the amount of pure oxygen available in the plant and whether the steam supply is balanced before deciding whether to use a steam-driven or electric-driven process.) Here are the actual operating parameters of our plant for your reference: 1. Production tasks: Using coke as raw material, along with pure O2 and CO2 as gasification agents, a new fixed-bed continuous gasification process is employed to produce crude CO gas. After compression and purification, this gas is used as a CO feedstock for the xxx facility. II. Brief description of the production process: Coke with a particle size of 25–60 mm is fed into the gasification furnace using an automatic coke feeder. CO2 from outside the reactor area, CO2 recovered from purification processes, and O2 from outside the reactor area are mixed in certain proportions and introduced at the bottom of the gasification furnace, where they undergo oxidation and reduction reactions with the hot coke. The crude CO gas produced in the gasification furnace is passed through a cyclone dust collector to remove dust, after which it enters a waste heat boiler to recover its sensible heat and generate steam. It then goes into a gas washing tower, where its temperature is reduced to around 40°C; most of the dust in the gas is removed during this process, and the resulting gas is sent to a gas holder. (1) The block diagram of the process flow is as follows: (2) The main chemical reactions are as follows: C + O2 → CO2 + 394.5 KJ/mol; (1) C + CO2 → 2CO – 168.5 KJ/mol; (2) C + 1/2 O2 → CO + 112.9 KJ/mol. The reactions primarily occur according to equations (1) and (2). Reactions (1) and (3) are highly exothermic oxidation reactions, while reaction (2) is an endothermic reduction reaction. (III) Process characteristics: (1) Continuous feeding, continuous ash discharge, and continuous gasification under normal pressure – a dry-ash-discharge gasification process. (2) The process flow is simple, and strict leak prevention measures have been adopted in the design to prevent CO leaks. (3) The gasification furnace has a large production capacity and is easy to maintain. Its special grate structure serves three functions: uniform gas distribution, slag breaking, and slag discharge, and the gas distribution across various layers can be adjusted according to the properties of the raw materials. (4) Using CO2 as a gasifying agent transforms waste into valuable resources, achieving both energy savings and environmental protection benefits. (5) The production process is easy to control; by adjusting the CO2/O2 ratio, the temperature of the gasification layer and the top section can be regulated, thereby achieving safe and stable production.

Could you please provide the equipment diagrams and the parameters for each piece of equipment upstairs? ? To supply 20,000 M3/H of CO, how many furnaces of what type are needed? ! ! Thank you! !

Which organization do you work for? What does CO need to do in the subsequent stages?

Oxygen production? Most methods involve purification through extraction... Regarding the first part, the method used to produce CO is different from that used in gasification furnaces; in gasification furnaces, coal slurry reacts with oxygen to produce CO and H2, along with a small amount of CO2

Dude, can you tell us the production capacity of the furnace?

This falls under the category of oxygen-enriched gas production. I know that Sanming and Huaihua are doing well in this area; you might want to consult them.

No, it’s oxygen-based gas production. Oxygen-enriched gas generation is generally used in the production of ammonia, while pure oxygen gas generation is typically used in the production of carbonyl compounds.

Do you have any experience in producing oxygen using pure oxygen? ? ? ?

Here, CO gas with a purity of over 98% is produced by burning coke in pure oxygen and CO2, using a generator furnace process (rather than a gasification furnace). The purity of CO is ensured by controlling the height of the carbon layer in the generator furnace as well as the ratio of CO2. The resulting CO gas undergoes processes such as dust removal (using spray towers and electrostatic precipitators) and desulfurization (via wet or dry methods), after which it is compressed to a pressure below 1 MPa and sent to the next processing stage. The most important thing is to control the pressure at the bottom and top of the furnace; when starting the furnace, the pressure at the bottom must not be too low, otherwise coke may fall into the oxygen nozzles ； The pressure at the top of the furnace should not be too high during operation, and protective measures (such as water seals) need to be installed. Be extra careful when adjusting the flow rate to protect the nozzle. Finally, the furnace temperature must be carefully controlled; the temperatures of the furnace walls and the outlet of the generator must not be too high. The cooling water system must be properly in place, including for the top and bottom of the furnace as well as the nozzles. It is best for coke to have a low sulfur content; otherwise, the desulfurization process that follows will require more pressure. Please think about this carefully

Hello, my company plans to use CO2 and pure oxygen as gasifying agents, along with coke as a raw material, and to employ fixed-bed gasification technology to produce CO for the subsequent production of calcium formate. What type of furnace is required for this purpose? Could you provide information on your company’s equipment suppliers?
