Newbie seeking help: How much acid can be produced from one ton of sulfur?

In the sulfuric acid industry, it is commonly said that one ton of sulfur produces three tons of sulfuric acid. The exact consumption amount must be calculated, and the yield depends on factors such as sulfur content, sulfuric acid content, conversion rate, absorption rate, and unknown losses.

The atomic weight of sulfur is 32, and the molecular weight of sulfuric acid is 98; with an overall sulfur utilization rate of 98.5%, the value is 98÷32×98.5% = 3.01656……

Generally, it’s three tons of sulfur per ton of sulfuric acid~

That can’t be right; it should be 98.5% divided by something, right?

Thank you all, experts :handshake :lol

For such questions, it’s best to first consult the book (reviewing old material helps gain new insights); rely too much on communication isn’t advisable, as everyone only has limited time to spend on forums.

It’s better to multiply by 98.5%: P. You can give it a try; if we assume that the overall sulfur utilization rate is only 50%, then 1 ton of sulfur can be used to produce over 6 tons of sulfuric acid! ;P

It’s better to use the commonly accepted figure of three tons of sulfuric acid per ton of sulfur, as that is what everyone agrees on:lol The last edit to this post was made by beiyue on 2008-4-15 at 14:51.]

The number of kilograms of sulfur consumed per ton of 100% sulfuric acid = 32/98 * 1000 / (conversion rate/100) / (absorption rate/100) / (1–unknown loss rate) / (sulfur content/100). Here, 32 is the molecular weight of sulfur and 98 is the molecular weight of sulfuric acid. The unknown loss rate is related to the management level of each company; it mainly refers to quality losses and losses that occur during startup and shutdown processes. In the 1990s, the Department of Fertilizers under the former Ministry of Chemical Industry established standards for this unknown loss rate: companies that meet the standards of **Grade II enterprises are assigned a rate of 0.5%, those that are considered clean and well-managed factories have a rate of 0.7%, while factories with no leaks or those that are recognized as advanced at the provincial level have a rate of 0.8%. For all other companies, the rate is set at 1%

What a noob; just give it to someone else to eat. Stop asking.
