Domestic market situation and scale of liquid sulfur dioxide
Thread Content
Dear seniors, I’ve looked up some information on liquid sulfur dioxide, and it seems that its production is carried out on a sporadic basis. I’m not sure what the current market situation for liquid sulfur dioxide is like What are the typical scales in the domestic market? Are there any that produce liquid sulfur dioxide at a rate of over 300,000 tons per year as well?
The largest scale in China is 2 wt/a; generally it’s in the range of several thousand tons, with a total demand of 40 wt/a. There are reviews on this topic
The largest domestic production capacity for liquid sulfur dioxide is 50 kt/a, using the sulfur-pure oxygen method, along with a supporting device for safety powder.
Consider upgrading to an liquid sulfur production capacity of 85,000 tons per year. Will there be a surplus in the domestic market?
