Modern automation solutions for papermaking wet end is a nice example how to utilize process analyzer as part of the machine controls. By wet end management we aim to have stable total and ash consistencies. drainage properties of the headbox suspension. and basic chemistryin paper machine short circulation. Stability is very important, because it's directly connected to paper machine runnability as well as to quality of produced paper. The level and variation of charge have a considerable effect on process status and operation. On-line charge measurement provides valuable information about the wet end chemistry of the paper machine. It is possible to perform charge contgrolbased on measurement by charge analyzer kajaaniCATi. The control provides many benefits for the papermaker. The benefits are process information, stability of process. runnability of papermachine and economical and effective use of chemicals.
