<p>A processing system utilizing heat recovery has a plurality of digesters in which products such as wood chips may be reacted at high temperature and pressure to form pulp suitable for use in the manufacture of paper. The digesters are fluidly connected to a plurality of heat recovery tanks including a cool liquor tank, a warm liquor tank, and a hot liquor tank. The digesters are also fluidly connected to a displacement tank which periodically supplies fluid to the digesters for the purposes of displacing their contents. The fluid levels within the heat recovery tanks and within the displacement tank are automatically controlled. In processing, predetermined volumes of cool and hot liquor are periodically pumped to each digester as well as automatically determined volumes of warm liquor and displacement fluid.</p> |
