【Q&A Question 096】April 06, 2017: Can a backwash filter be connected using cross-wiring? (Unless otherwise specified, all questions and answers are based on hydrogenation units.) ) After *relying*, the reference answers can be seen; scoring is obtained by answering the key points. Under normal circumstances, it is not allowed to cross tracks. 2017 Q&A Summary Thread (updates have begun) http://bbs.hcbbs.com/thread-1657793-1-1.html 2017 Daily Question Summary Thread (updates have begun) http://bbs.hcbbs.com/thread-1657794-1-1.html 2016 Q&A Summary Thread (updates completed) http://bbs.hcbbs.com/thread-1597792-1-1.html Third Phase of Haichuan’s Outstanding Management Members Selection Contest http://bbs.hcbbs.com/thread-1655902-1-1.html (Source: Haichuan Chemicals Forum)
It is possible under special circumstances, but impurities in the pipes as well as those in the oil may enter the downstream system
It is possible to cross lines； When a backwashing failure requires repair, the time taken must not be too long to prevent damage to the catalyst.
It is not allowed to cross lines; doing so will allow contaminants present in the raw materials to enter the reactor, causing catalyst blockage and an excessive pressure difference in the reactor, which will affect production over time
