Because spills and losses of process materials are unavoidable consequences of production processes, and because the processes comprising the production of chemical wood pulp use large amounts of water to transport heat, chemicals and product through the processes, there is a need for a management strategy and system to control these intermittent spills and losses. In order to develop feasible strategies, examination and characterization of process effluents from many kraft pulp mills and investigation of existing loss control systems in the industry were conducted. Dynamic computer modelling, using data obtained from monitoring process effluents, was employed to illustrate the utility of this technique to arrive at various loss control strategies for particular process configurations. The installation of a loss control system for other than environmental reasons should show a return on investment. Examples were presented, using data obtained from the monitoring effort, of the net economic benefit which may accrue from recovery of chemicals and organic solids. A loss control strategy was developed for the pulping, pulp washing, and chemical recovery areas of a large kraft pulp mill. The strategy was implemented and operated in the existing spill control system of the mill and control was successfully effected utilizing a digital computer. In addition to managing process losses, the direct digital control system also allowed gathering, processing and managing data obtained from the sensors monitoring the system.
