The specification of an integrated pulp and paper factories White Board conducted a preliminary design, elaborated on the necessity and possibility of plant and at the same time address expressed the choice of plant, plant to the meteorological conditions, as well as personnel. Since the focus of network design and process design of the press section, in calculating the balance serofluid process, only the network and the process of pressing the Department, including the press section, V roller, vacuum tanks, network case, the net box, roll-volt pool, a few steps rotary compressor. In the process of selection of equipment, the design only on the Department of Press and network equipment selection and related calculations. Paper-making equipment, 150 tons per day production of the 2640 paper, the key parts of the import, the rest of the use of domestically produced equipment. The statement of the equipment and the choice of the number of working staff, the production process to identify broadly with reference to Yangchun Fu Sheng Paper Co., Ltd., the plant in its choice of equipment, etc. have considerable experience, with reference value. Design elements include mapping serofluid balance calculation, the Department of Network and press production process map, workshop equipment, floor plan, equipment list of the drawing. KEYWORDS: pulp and paper, white carton, network department, squeezing department
