Why has ex-sulfidation of hydrogenation catalysts not been widely adopted?
Thread Content
The first industrial application of out-of-vessel vulcanization took place in 1986, and it is expected that the number of catalysts used for out-of-vessel vulcanization will increase rapidly. It also has the following advantages: extracorporeal vulcanization **reduces environmental pollution, decreases the occurrence of accidents in refineries, and shortens the time required for pre-vulcanization in refineries. Why has external sulfidation of hydrogenation catalysts not been heard of much – is there any plant that uses it?
There are many applications of this method these days; it’s just that the cost used to be high. In-situ vulcanization is cheaper and more convenient, which is why it wasn’t widely adopted. Now, due to environmental regulations, in-situ vulcanization may pose pollution issues, so it is being replaced by off-site vulcanization
There are many such options that help save startup time and make the site more environmentally friendly
