Let’s talk about the water-in-oil interlock in the butadiene plant
Thread Content
My butadiene ACN unit is equipped with two-position interlocks for automatic dehydration, which are also used for interlock management; since an alarm is generated in the DCS every time dehydration takes place or is stopped, I would like to optimize this setup. Is it possible to eliminate the interlock management?
； Since it has been designed, it cannot be canceled in principle ； I don’t understand why interlocks were installed in the first place, or what the purpose of interlocks is ； Here, the water displacement process for butadiene using the acetonitrile method is entirely automatic; there is no interlock system in place ；
The so-called automatic drainage system on the upper floor is actually our interlocked two-position control; I’m not sure if what you use is a position control system rather than a two-position valve.
