ABSTRACT:
Novel pulp, paper and paperboard manufacturing methods utilizing water-insoluble organic hydrocarbons. These hydrocarbons can be introduced into the pressing operation of the pulp, paper, or paperboard making machine or can be substituted for water at any point prior to the end of the press section. The result is a significant saving in dryer energy which can be translated to greater productivity in dryer-limited processes. The result is a significant saving in dryer energy which can be translated to greater productivity in dryer limited systems. Functional chemical additives may be dissolved, dispersed or emulsified in the hydrocarbon and thereby introduced into the web. Much less functional chemical additive is required than with wet end addition.
