Nowadays, a low-carbon approach is being promoted, and carbon emissions are regarded as an important indicator; but what exactly should be used as the basis for calculation? I spent a long time trying to come up with a method; I’m not sure if it will work, so I hope everyone can discuss it and offer their advice. Taking methanol as an example, the consumption quota (excluding water) is converted into “tons of standard coal per ton of methanol”. Then, this value is converted using the commonly used figure of “tons of carbon emissions per ton of standard coal”, which is 2.493 tons per ton of standard coal. However, since standard coal used as a raw material does not emit carbon, the amount of standard coal consumed for energy purposes in the “tons of standard coal per ton of methanol” figure is separated out and converted separately, thereby yielding the final accurate figure for carbon emissions.
