Issues with the catalytic activity of sulfuric acid
Thread Content
Premise: Correct process, equipment design, and proper operation (sulfur-based acid production, 3+2 process, 2 conversion stages and 2 absorption stages), along with the use of imported catalysts, can ensure a conversion rate of not less than 99.9% within 2 years? @Zhang Ruqing @Danzhi @Pei Qinghua
It’s possible; the loading capacity will just be higher, and there will also be requirements regarding other accompanying conditions such as the heat exchanger.
700t/d sulfuric acid production, using VK38/48,3+2, with an overall conversion rate of over 99.92%
More or less, it’s not overloaded; it should be fine
Is it necessary to increase the conversion rate by 99.9%? All current systems require the installation of a tail suction device; otherwise, the exhaust emissions will not meet the standards.
As long as the exhaust emissions meet the standards, a high conversion rate is not necessary; sometimes it is even necessary to reduce i to meet the requirements of subsequent processing stages
The client requires a total uptime of no less than 99.9% over 2 years, with a production load of 110%
