TRANSPORT OF SOLUTIONS OF CELLULOSE THROUGH PIPES

摘要

A method for transporting a solution of cellulose in aqueous N-methylmorpholine N-oxide through a pipe, the temperature in degrees centrigrade of said solution in the centre of said pipe being controlled at 1000/(X + 0.19 x?D) and/or the temperature of said solution at the interior wall of said pipe being controlled at 1000/(Y + 0.23 x ?D) where D represents the internal diameter of the pipe in millimetres, X represents a value equal to or greater than 5.0, and Y represents a value equal to or greater than 5.4.
