Paper and Pulp
Pressure, liquid level, and flow measurement and control in paper and pulp
The paper industry places high demands on the productivity and availability of equipment. Micro Sensor understands these requirements and provides suitable sensors for pressure, level, and flow measurement which are durable, long-term stable, and easy to maintain.
The papermaking process generates large amounts of pulp and chemicals, requiring the use of towers, pools, tanks, and other containers for storage and transportation. Installing intelligent pressure transmitters that can work in conjunction with computer control systems allows for timely monitoring of pressure, differential pressure, and flow information, effectively improving production efficiency and reducing losses.
In the paper industry, the alkali recovery system is an essential part that operates under harsh conditions. The system needs strong pressure, temperature, and flow instrumentation to handle high temperatures, high pressures, and corrosive media.
The pulp undergoes high-temperature bleaching in a tower using peroxides, ozone, or oxygen to get the right white color. The tower usually stays empty while the large amount of bleached pulp is dumped via a screw conveyor.
Large, high-capacity pulp storage towers with agitation homogenize the prepared pulp to guarantee continuous paper mill operation. Pump operation produces steam from the heated, agitated pulp, which also causes level oscillations.
