It was found that at present partial borate autocaustization is technically possible and cost effective, in particular in sulphate pulp mills where the caustization and lime kiln department is aA method of firing a lime sludge reburning kiln with a solid fuel at reburning of lime sludge (CaCO.sub.3) to burnt lime sludge is described. The solid fuel is gasified under supply of air to form hot flue gases in a cyclone gasifier, which is built in conjunction with the lime sludge reburning kiln, at a temperature in excess of 1000.degree. C., at which temperature ashes formed melt, after

BLG can be integrated in a future modern, ecocyclic, pulp mill biorefinery for the production
scenarios with other lime kiln fuel production methods: Heavy fuel oil, bark gas, and both tall oil pitch and bark gas. Tall oil depitching was concluded to be feasible with short payback period and good applicability to pulp mill. The major technical drawback of the process is that it is not sufficient to provide all of the lime kiln fuel needed.Author: Brian Richardson

HANNUS (Finland)Purchased lime kiln fuel further increases the surplus by 5 10 %. On the other hand, acidulation of tall oil soap adds about 1 3 kg SO2 for t of pulp onto the difficult to manage sulphur balance of the mill. Pyrolysis or gasifiion of tall oil soap could alleviate both these problems.
