Quality
A high SAP result is obtained in 4D102- what's next?
25% blendaway in test tank (TK134/TK137) for a SAP number between 63 and 65 mgKOH/g OR SAP number between 72 and 75 mgKOH/g. If higher may need to dispose of product
Boron is slightly low on finished C9231 in 143TK- what's next?
when it doubt add in an extra 2000 lbs of boric slurry
List your key EOWs to check in on between TDU and Chloro
- U value for 4E102/104
- flame arrestor DP
- FUNDA (vibs, torque)
- 8R ovhd pressure
-U value for 22E3
Viscosity in the test tanks is trending low and we enter summer month- what do you do?
reduce base oil overflow charges
Going into the weekend we anticipate bottling necking P112 production due to rundown room- what can you do to optimize the run plan
- move material to 156TK
- review with katelyn if any boration batches can be pulled up
- swing reactors to heavy
We are seeing a lot of delays in the snap dry step - what can we do to optimize?
review if we need to lower the set point on snap dry pressure if grid pressure if running low
C9202 fails Turbiscan- what are the next steps?
Notify MFT/PTL, determine if material can be consumed by blending or other side. If it is going to be held in storage make sure material is put into block stock.
the filter aid drop leg to 4H401 plugs and will not be able to be resolved until maintenance comes in the next morning- what should you if there is a batch holding in 4R1/2?
cool batch to 350 F. Do not re-heat before pumping to 4D102, re-heat in stripper after pump over to prevent additional SAP growth.
You're starting to see gaps between step 3 and 4 on the FUNDA- what does this mean and how can we fix it?
adjust maleation batch stagger to be more aggressive
You're in the middle of charging maleic when downstream failure happens that will cause delays. What should you do?
reference SAP forcasted value in the GPROMs program and review if the maleic charge should be reduced or not.
The turbidity analyzer at the FUNDA flatlines at 150 PPM - what do you do next?
ask for a sediment sample at the material on the filtrate for rundown and see if any filter aid is present indicating breakthrough.
The THOX isn't maintaining it's set point of 1700 F - what are some things that you can look at?
- sweet gas flow rate
- air flow
-waste gas flow
- CEM value
Chloro dispersant amination/boration often requires fixes- can you explain how they effect visc/N2
pibsa fix will increase visc and decrease N2
base oil fix will lower visc
there is a leak on at the PIB nozzle inlet for 4R1 and 8R4 (tough day). Material is already filled to ~20% level in teh reactor- what can we do with the batch?
For both the 4Rs and the 8Rs material can be transferred from one reactor to another in order to finish a batch that is in progress
You're mid way through chlorination and the THOX trips. The mixer stays on in the 8Rs and continues to raise the temperature - what can you do?
Turn the mixer off to try and lower temperature before resuming chlorination and hold for sample results before pumping out
