Optimal grade transition based on residence time distribution of catalyst particles in bimodal polyethylene production process
The sludge residence time in the screw press and thus the filtration time can be adjusted to individual requirements by adjusting the rotational speed of the screw shaft.
The method is characterized by minimizing residence time of steel strip in contact with the aluminium-zinc-silicon alloy bath in the pot.
Result: There were significant differences between the result of different residence time and different injection site, while no difference was found in weather the local skin was pinched or not.
