At the Weyerhaeuser pulp and paper mill in Longview, Washington, the proposed addition of a digester heat recovery system was expected to result in annual natural gas savings of 130,000 MMBtu, leading to $280,000 per year in cost savings (US DOE, 2004). In a 1000 t/day pulp mill up to 200 MMBtu heat per day can be recaptured.
chamber pulp lifters for one of their mills at the Wagerup refinery. One of the main challenges presented in development of the Twin Chamber Pulp Lifter was the issue of turning the conceptual idea into a product for installation into appropriate mills. Although simple in concept, mill operators and researchers were familiar
Pulp Mills originally installed co-generation to take advantage of the higher efficiency of highpressure boilers - – 4000 to 6000 kPa. Backpressure and automatic etraction x turbines extract the work available in the high-pressure steam. Pulp and paper mill production units need process heat, typically at pressure levels of 1100 kPa and 450 kPa.
In North America, the first pulp mill was built in Germantown. By 1810, there were more than 185 mills operating in the U.S. Raw materials for pulp mill include softer, smaller trees like fir, poplar, balsam, and hemlock.
