VALVE SOLUTIONS FOR THE PULP & PAPER INDUSTRY
www.dezurik.com2 © 2021 DeZURIK, Inc.
The DeZURIK DifferenceThroughout our 250 years of combined history, DeZURIK, APCO, and HILTON have been recognized worldwide for collaborating with customers to design and engineer valves that provide superior performance and value. Each company was founded by an innovator who set out to solve a customer’s problem application.
DeZURIK’s founder, Matt DeZURIK, started designing products for the Sartell Paper Mill in 1925 that included knot boring machines, consistency transmitters and shower pipes. When he noticed that valves weren’t able to seal due to pitch build-up, he invented the first Eccentric Plug Valve – a design still in use today, dutifully solving sealing problems worldwide.
Today, the DeZURIK, APCO, and HILTON brands continue the tradition of partnering with our customers in the Pulp & Paper industry to provide the newest innovations in control, gate, plug, butterfly, automatic air and check valves. Our vision is to deliver exceptional value to our customers by applying our valve and problem-solving expertise to improve their operational performance.
Full-Featured Valves for Today ApplicationsDeZURIK recognizes the importance that control valves can play in process control performance and productivity. That’s why DeZURIK is dedicated to control valve testing. Regulating critical aspects of control valve performance such as accuracy, hysteresis, deadband and response time ensures that DeZURIK control valves provide optimum performance and help reduce costs.
DeZURIK’s original Eccentric Plug Valve, developed in 1925 for the Sartell Paper Mill to solve a problem with pitch build-up.
DeZURIK Knife Gate Valves and V-Port Ball Valves are widely used in pulping and stock prep operations throughout the mill.

Digesters are used to break down the wood chips and soften their composition. To accomplish this, steam is added to cooking vessels along with the chips, white and black liquors. The temperature is increased until the chips reach a point where they start to breakdown. At this point, the blow valve is opened and the chips are blown into a tank where they impact the wall and break into fibers.

In this method of pulping, logs are mechanically chipped and are softened with steam. The chips are then broken down into fibers in a refiner.
- Fresh steam is typicaly 15-30 psig, 250-280º F- Process steam is typically 60-75 psig, 300º F- Some fibers are present in process steam

First the wood is mechanically chipped. The chips are then heated and chemically treated to reduce the bonding properties of the fiber’s lignin and to soften them. Two chemical processes are used: the kraft process (alkaline) and sulfite process (acidic).

After the stock is injected at high velocity into the blow tank and the chips are broken down into fibers, a deknotter separates the chips and knots. The knots are then discarded or sent back to the digesters for further processing. The pulp (cooked fibers) is washed to remove residual liquors that will contaminate the process and also to recover the maximum amount of chemicals. The spent chemicals that are recovered go to seal boxes and then are reclaimed for later use. The washed pulp is pumped into high-density storage tanksand from there it goes to the bleach plant or to the screen room.

The highly concentrated black liquor is sprayed into the recovery boiler and the heat generated from this is used for making steam to run other parts of the mill. The inorganic smelt that forms as the black liquor is burned flows to a smelt desolving tank where it is cooled and desolvedin water forming unclarified green liquor.

Recaustisizing is the process where green liquor (sodium carbonate Na2CO3) is converted into white liquor (sodium hydroxide NaOH). First the green liquor is clarified to remove any dregs,then the lime (CaO) is added to form white liquor. Next, the white liquor is clarified to remove lime mud (CaCO3) and is returned to the digesters for cooking wood chips. Finally, the removed lime mud is sent to the lime kiln to form lime through a high temperature reaction.

The bleaching process occurs in multiple stages. Pulp stock can be whitened by either brightening or by removal of the lignin and is accomplished with the addition of chemicals.The pulp stock is washed between each stage and stored. Typical bleaching stages include chlorination, alkaline extraction, oxygen, hypochlorite, chlorine dioxide, peroxide and ozone.

The basis weight valve is used to control the amount of stock to the head box and is positioned by the mill’s Distributive Control System (DCS) or the gauging system which measures the density and thickness of the finished sheet of paper.
Basis weight control requires constant pressure and consistency to the valve. Alternatively, this loop may be controlled by a Variable Frequency Drive (VFD) that would not require a valve.

The paper machine dryer removes any residual water through evaporation as the sheet passes through heated steam rollers. A condensate system collects water from the steam for reuse in the mill. In order to reduce energy consumption, water is continually reused in the mill. At the dry end of the paper machine, separators pull water into the mill‘s condensate system for eventual reuse.
