Intense activity in low-temperature waste heat recovery using sulfuric acid

Thank you to the moderator for providing so much relevant information; however, it seems that there isn’t much information in these posts regarding the comparison between imported and domestic technologies. Currently, there is ongoing debate about which one is superior; it would be useful to conduct a comprehensive comparison based on overall cost-performance. Do not overemphasize the initial investment, nor should you constantly promote long-term operation. I’m not sure how to determine this “degree”?

The use of low-temperature waste heat recovery technology for sulfuric acid has now enabled the utilization rate of its waste heat to exceed 90%. Does this mean that the field of sulfuric acid waste heat recovery has reached its peak? If trying to improve efficiency further, isn’t it somewhat not worth it?

HRS is great; foreign devices are way too expensive, so costly! The cost of setting up an HRS system is measured in hundreds of millions; it takes around 10 years for the investment to yield returns

There are now several domestic engineering companies that work on this kind of technology; the domestically produced units in Shangyu, Zhejiang, have been in operation for quite some time already. As for the others, it remains to be seen how they perform over time. 5# yunsgx1983 gmd

I mainly study this field; the prospects are good at the moment, and there are quite a number of projects available

From a long-term perspective, I think I should go for it. Of course, it depends on whether the conditions permit. HRS is a great thing

It’s time to act. Mengmoke (the domestic partner for waste heat recovery, Shanghai Hailu Kunlun) performs very well in large-scale installations across the country; one could take a look at the 1 million tons per year plant in Zhangjiagang operated by Shuangshi, as well as the several facilities owned by Yuntianhua International Chemical. Of course, since all the equipment has to be imported, the cost is naturally high! The domestic Ogris uses homegrown technology, but the reliability of large-scale installations requires time to be verified! !

As the original poster hopes, the sulfuric acid industry is all focused on determining whether HRS offers good value for money. People say one thing but mean another – could someone provide a more comprehensive evaluation? Experts, please

Thank you; it should lead to positive developments.
