Steam stripping foul condensate more efficient with spiral heat exchanger use

Steam stripping is a common treatment technology to remove pulping and wood chemicals from the condensate due to the relatively low installation and operating costs of this type of system. The proper design of the column preheater is critical to ensure maximum efficiency and reliability of the system. In many mills it is important to the overall efficiency of the system to recover as much heat as possible in the heat exchanger to minimize steam costs. The spiral heat exchanger is designed to meet this requirements. It has low operating costs due to lower fouling tendencies and more efficient heat recovery. Its life cycle costs are less due to lower maintenance costs and downtime.
