Title:
METHOD OF CONTROLLING FILTRATE FLOWS AND STORING OF FILTRATES OF A FIBRE LINE IN A PULP MILL
Document Type and Number:
WIPO Patent Application WO/2011/095686
Kind Code:
A3
Abstract:
The present invention relates to a method of controlling filtrate flows and storing of filtrates of a fibre line in a pulp mill. In the method, the fluctuations in the amount of pulp in the pulp storage tank (3, 8, 17, 37) are not compensated by a separate filtrate storage tank, but the aim is to maintain the amount of filtrate in the pulp storage tank (3, 8, 17, 37) steady. When the amount of pulp changes, it is not that much the volume of the pulp in the tank (3, 8, 17) that will be changed, but the average consistency of the pulp in the tank.
