[Solved] Question: For the methanation unit used to remove carbon monoxide in a 1 million-ton ethylene plant, what is the amount of catalyst required?
Thread Content
I have a practical process-related question: in an ethylene production plant using thermal cracking, there is a methanation unit designed to remove carbon monoxide from the cracked gas (converting carbon monoxide and hydrogen into methane). What is the amount of catalyst required for such a unit (taking an annual production of 1 million tons of ethylene as an example)? Which companies produce this commercial catalyst?

It depends on your operating conditions; you will have a large volume of air flow
Shell CRI has extensive experience in methanation operations for ethylene plants. A usage volume of 1 million tons corresponds to roughly ten to dozen tons
