Pulp and Paper Industry Applications for Level Measurement

Challenges: Two vessels in a typical recovery system require level control of the turpentine/water interface: the decanter, or separator, and the storage tank.The National Fire Protection Association (NFPA) rates turpentine as a "severe fire hazard." For this reason, the decanter is contained in a dyked area, storage tanks are sometimes located below ground, and controls must be rated

If the spent pulping liquor could be gasified (or combusted in a high efficiency steam boiler), the excess amount of electricity would be about 1500 kWh per ton of the pulp produced (or 900 kWh per ton of pulp in the case of high efficiency recovery boiler). This is 3 to 5 times more than the excess electricity obtained in today's modern pulp
