Abstract

The No 1 and No 2 Lime Mud filters of Asahikawa Mill started in 1960 and 1972 respectively. To release plugged filter, accumulated lime mud have been blown off using blower machine so as to renew pre-coat layer periodically.Air blowing is not completely efficient so hydrochloric-washing work is necessary for these filters. Furthermore, the moisture of sludge fluctuates, and rotary kilns are thrown into unstable operation, therefore consumption of heavy oil tends to increase. After installing CPR (Continuous Pre-coat Renewal), lime mud feed is stabilized and pre-coat blow-off is avoided.This paper describes results on saving heavy oil achieved from the installation of CPR system.
