Reaction shutdown and coking

Each time there is a shutdown, coking in the settler becomes severe. Is there any decoking plan for shutdowns that can be provided? jbcyf@163.com

The coking in the settler is severe; fundamentally addressing this issue is the long-term solution.

The anti-coking steam can be replaced with superheated gas; this will **improve** the coking phenomenon. In our 600,000-unit catalytic system, there has been almost no coking after three years of operation.
