How much methanol can be produced from 1 cubic meter of syngas? ?
Thread Content
As the title says! ! ! ! Can up to 208 grams of product be synthesized from 1 cubic meter of CO+H2 syngas? ? ? (I’m not sure if it’s correct?) ? ) May I ask, how much methanol can be contained in this 208? ? ? Please give me some advice! ! ! !
What are the specific components and their concentrations in 1 cubic meter of syngas? It’s impossible to calculate without this information. Different gas production methods, purification processes, and synthesis processes can result in varying components and concentrations of syngas; therefore, the original poster should provide exact figures to facilitate calculation
Then please tell me, for different production processes, how much methanol can be produced from 1 ton of coal?
The composition of the syngas varies, and as a result, the amount of methanol produced also differs. In some syngases, CO and H2 account for only about 70% of the total volume; the remaining components are CO2, CH4, etc. There is also the issue of the volume of gas that is vented. In our facility, approximately 2500 cubic meters of syngas are required to produce one ton of pure methanol. Therefore, 1 cubic meter of syngas can yield 1,000,000 g / 2500 m3 = 400 g/m3 of methanol
Different coals and different gasification processes result in methanol of varying quality
It’s more accurate to convert using the calorific value of your raw coal. Look at the calorific values of CO and H2 in your syngas; these remain constant. Knowing the calorific value of methanol, you can calculate the required calorific value of the syngas, and then by considering mass/volume, you can obtain a value suitable for your syngas: D
Actually, this can be calculated easily by oneself, but I’ve still learned a lot from everyone’s valuable insights!
Mathematically speaking, to produce methanol from carbon monoxide, 1 MOL of CO and 2 MOL of H2 are required per 1 MOL of methanol produced; the reaction is CO + 2H2 → CH3OH. Thus, to produce one ton of methanol gas, 1000*22 units are needed. 4/32=700 M3; therefore, 700 M3 of CO is required, and 1400 M3 of H2 is needed. This allows us to calculate that the amount of methanol produced per cubic meter of syngas is 1000/2100=0. 476 kilograms of methanol. However, in actual production, there are also reactions between CO2 and H2, as well as side reactions and some unreacted substances; therefore, it is necessary to consider the composition of the actual gas.
In fact, the volume fraction of CO + H2 in syngas is around 80%, with small amounts of CO2, CH4, N2, etc. (I’m referring to natural gas methanol; I’m not familiar with the situation regarding coal.) Therefore, each cubic meter of syngas can produce approximately 400 grams of methanol
It depends on the specific process and gas composition; taking factors such as the inert gases present into account, it takes approximately 2500 Nm3 to produce one ton of alcohol, and I’m referring to coal as the raw material
I would like to ask for more specific information regarding MA. For example, the calorific value of coal is 6000 kcal/kJ, while that of methanol is 4650 kcal/kJ. How should it be calculated? . I don’t know if a consumption quota is required. . For example, how many standard cubic meters of syngas can be produced from 1 ton of coal, and how many tons of methanol can be manufactured from that syngas? . I’m new to this field and don’t understand much yet; I hope you can offer some guidance.
The latest comprehensive energy consumption requirement is 1.4 tons of standard coal per ton of methanol produced; do the conversion by yourself
For our Texaco process, 0.88 tons of raw coal and 0.43 tons of thermal coal are required per ton of methanol produced! Please convert it for me
0.88? ? ? ? ? ? ? ? ? ? ? ? ? ! ! ! ! ! ! ! ! !
Calculating this must also be related to pressure, right?
0.88 – that is indeed low. What is the calorific value of your coal? If calculated using the conversion factor method, this figure cannot even be achieved in China; I know that the best value is around 1.2, and with the additional factor of energy consumption, a value of 1.35–1.4 is already considered very good. But your power consumption for coal is a bit high.
The calorific value of 1 ton of methanol is equivalent to 1.37 tons of standard coal.
Going to visit the carbon equivalent of one ton of methanol – calculate it yourself.
For your Texaco process, 0.88 tons of raw coal are required per ton of methanol produced； That’s impossible ； Which company ； If it’s 0.88 ； Then all of our businesses are going to have to close ； Our water-coal slurry is around 1.26
Yes, it’s rare for the raw coal quantity to exceed 1 ton; it’s usually around 0.9 tons. For thermal coal, it’s around 0.5 tons. This isn’t just something I’m saying arbitrarily – there’s no point in making up such figures. It might be related to the quality of the coal being used
