I want to ask how many factories actually have a methanol hydrogen carbon ratio of 2.05–2.15

As title
There are also those with a fresh gas flow rate of 1.8 and 2.5; the synthetic equilibrium can be maintained through vent gas recovery methods and other process aids.
I think it should work fine in most cases; by adjusting the operation properly, maintaining a fresh gas hydrogen-carbon ratio between 2.0 and 2.15 shouldn’t be a problem. The hydrogen-carbon ratio of the synthesized gas also fluctuates within a certain range, so based on the requirements for synthesis, the hydrogen-carbon ratio of the fresh gas is generally around 2.0–2.15 as well
First, you need to understand the concept of the hydrogen-to-carbon ratio in methanol synthesis. CO2 + 3H2 = CH3OH + H2O; CO + 2H2 = CH3OH. From these two main reaction equations, it can be seen that when the ratio of the amounts of hydrogen to carbon in the gas fed into the reactor satisfies H2/CO2 + CO/CO2 = 2, the reaction can proceed completely and efficiently. The range of 2.05–2.15 is chosen to ensure a slight excess of hydrogen, thereby guaranteeing complete conversion of the carbon components. Therefore, controlling the hydrogen-to-carbon ratio at 2.05–2.15 is based on the composition of the gas entering the tower. It’s just my personal opinion; I hope it can help you.
Is there also one with a hydrogen-to-carbon ratio of 1.8? In that case, the hydrogen level won’t decrease, but side reactions and carbon buildup will occur, right?
May I ask if your hydrogen-to-carbon ratio is kept within this range? What is the gas consumption per ton? Our fresh gas hydrogen-to-carbon ratio is around 2.4, with a gas consumption of about 1,890 per ton. On top of that, the consumption of fuel gas exceeded the company’s target. May I ask what your char-to-steam ratio and char-to-oxygen ratio are? What is the gas temperament?

We will keep it within this range, with a gas consumption of around 2100-2200 tons.
So your gas consumption per ton is quite high; ours is currently over 2,000, and the company still has to prepare a summary
The hydrogen-to-carbon ratio of the fresh gas is 2.4; therefore, the flare gas is fed back into the furnace for combustion. The oxygen-to-carbon ratio is increased slightly along with the load, and the flare gas is used to replace coke gas in the methanol production process.
Production personnel need to be well aware of the hydrogen-to-carbon ratio of the fresh gas, that of the syngas, the hydrogen-to-carbon ratio of the recycled gas, and related factors.
I would like to ask what the optimal ratio for these indicators should be, and I’d like to see how other manufacturers handle the relationships between volume, capacity, and consumption. Also, we carried out carbon supplementation after the rough removal process, and we’re not sure how to control an appropriate proportion for this

Hello, what is your total carbon content in the gas? What is the gas capacity? What is the unit consumption? After carbon supplementation, no
