Hi Friends,
up to now i shared structure of batch reactor and instrumentation regarding bottle filling section of batch reactor using B n R PLC.I also shared cable laying for instruments which are required on batch reactor.i am sure you are now waiting for the batch reactor instruments for which we done cable laying.
Here are the instruments which are mounted on batch reactor.
1.Solenoid valves are used to control the inflow into the three ingredient tanks.
These are inch line size and have direct 24V DC electrical actuation. They have
been fi tted to the tanks with appropriate barrel nipple and reducer assembly.
There are 3 solenoid valves which are mounted on the upper side of 3 tanks for ingredient inflow.
I want to mention one important thing that cable for these valves comes directly from DCS panel,there is single JB connection for these cables in process lab unlike other Multicore cables.
In case of failure:first check actuating supply to the coil,in our case its 24 V d.c. if not then,follow these steps-
a.cable connections,check cable continuity.
b.If cable continuity is OK,further check 24v dc from card, check also whether channel is enable or not in DCS.
c.If 24 v d.c is coming then may doubt on coil.
2.Angle valves with pneumatic actuators are used to control the ingredient
inflow into the reactor assembly. The actuators are electrically actuated with 230V AC supply controlled through DCS via a relay mechanism. These valves are also 3/4 inch line size and are specially designed to achieve better flow rates.
Cable connections from DCS to B n R panel into TB4 and further it goes to angle valves through relay.24 v dc coming from DCS and through relay 110 v ac or 130 v ac going to the coil depending on its specification.So when coil actuates,it gets magnetized and air supply enter into actuator and valves open.
Troubleshooting procedure same as that explained in angle valve,just check the coil procedure.( whole B n R panel picture should be uploaded soon,so u can check where is TB4 location )
3.Fi ne and coarse valve assembly is tted at the outlet of the reactor tank for bottle lling purpose using appropriate barrel nipple and reducer assembly.Note that these both valves get 24 v dc from b n R panel which is explained earlier.
4.switches and transmitters are mounted on each tank to provide high and
low level alarms for each tank as well as continuous level indication and control for the reactor tank section.these are as follows :
Tank 101: Conductivity Type Level Switch (HL and LL)
Tank 201:Displacer Switch (HL), Magnetic Float Switch (LL)
Tank 301:Capacitive Level Switch (HL), Vibrating Fork Switch (LL),
Ultrasonic Transmitter for continuous analog level reading.
Reactor :Capacitive Level Transmitter for reactor level measurement
