Area 1/2
If this is inconsistent it will affect viscosity and filterability of the flake.
What is pulp feed?
This quality parameter is known to not blend well in the bottom of the blending silos.
What is high moisture?
This is the reason sampling times and standard results are so important.
What is results accuracy?
This is done to verify that readouts from online analyzers used to control the process are accurate.
What is Calibration?
This is the concern during unloading if the moisture of a load is too low.
What is explosion risk?
When sulfuric acid concentration is changed, this part of the process may also need adjusted.
What are hydrolysis tower levels?
Over-stabilization during the washing step can lead to issues with this quality parameter.
What is color?
This is the impact in Area 12 of too much water in ARD7B.
What is drum flakers won't freeze?
This is done before a problem occurs in order to keep equipment working at its best and prevent costs in the long run.
What is Preventative Maintenance?
This Quality parameter of the flakes affects the solubility during mixing in the tow sites.
What is acetyl?
This quality parameter tells us if a quality issue originates in Area1 or later in the process.
What is high water coulter count?
This is where the acid inside the pellets diffuses out and the outer shell of the flakes begin to harden.
What is maturation?
This Quality parameter can be impacted by the acid and other raw material purity
What is Color?
If, after an issue, this is found and repaired a failure should not reoccur.
What is the root cause?
This is the most important raw material in filter tow production.
What is Cellulose acetate or flake?
Non-homogeneous acetylation can result in quality issues in these 2 parameters.
What is fiber and viscosity?
Issues with this quality parameter are often started in the precipitation step.
What is grain size distribution?
These 2 acid contaminates could impact odor for both us and Eastman.
What is Butyric and Propionic Acid?
The process of checking a maintenance task was completed correctly including inspection, testing and monitoring performance of equipment.
What is Quality Control?
This flake parameter can be high with low coulter count, leading to lint problems in the tow sites.
What is Haze (particles less than 4 microns in size)?
These 3 things are how the chemical processes are controlled.
What is time, temperature, and catalyst concentration?
Area 3 has the greatest impact on this part of the tow process.
What is storage?
If you run the same sample multiple times, this is the name for the variation between the test results.
What is precision?
This metric measures the process efficiency based on availability, performance and quality.
What is OEE (Overall Equipment Effectiveness)?
This Tow parameter is affected negatively most by gels from the flake coating the spinning system
What is pressure drop?
