How many devices cannot be turned on?
Thread Content
In our chemical industry, it costs a lot of money to put a production facility into operation. However, I’ve seen many such facilities that have been built end up unused, and many of them were originally considered “high-tech” projects; people just don’t dare to start operating them. Is it the market? Cost? Technology? Please talk about how many similar devices you have seen and what the reasons are Can it be saved?
Are there any real scientists?

It would be best to start with a preliminary discussion – for instance, by mentioning that \"I’ve seen many completed installations left unused, and many of them were originally ‘high-tech’ projects proposed during the planning stage.\" “Market? Cost? Technology? ”Factors other than these include changes in policy restrictions, the thoroughness of project approval processes, oversight and inspections regarding share investment, disruptions in the capital chain, as well as issues related to safety and environmental protection.
What I have seen includes: PPS project, polymethoxymethane project, polyarylether nitrile project, acrylate rubber project...； These are all high-tech, right?
Our unit’s environmental protection device absorbs hydrogen sulfide from the refinery. High investment, all stainless steel equipment. An immature manufacturing process is being used. It can barely be produced, and the products can’t be sold. Production can only be halted.
Is that the desulfurization unit? Wet flue gas desulfurization is quite mature ； Dry methods also have mature ones ； Of course, valuable products can also be produced from H2S
In the production of sodium hydrosulfide, incomplete separation of carbon dioxide from hydrogen sulfide causes liquid alkali to react with carbon dioxide to form sodium carbonate, thereby blocking the pipes.
There used to be a state-owned enterprise with an old facility; it imported a caprolactam production plant from France, built it up, but didn’t dare to operate it, and the more it tried to do so, the greater the losses became.
The market has changed, and the technologies have become outdated; some companies’ acetic acid and PTA production facilities have been idle for several years.
Optimize the process – even if it’s acetic acid as the product, it should still be profitable
Optimization: caprolactam is very promising
