Abstract
KBR (formerly Kellogg Brown & Root) carried out a feasibility study for the University of Minnesota for a greenfield cereal straw market pulp mill in Minnesota. Two processes were evaluated: (1) a soda-AQ process with an ECF bleaching sequence, and (2) an ethanol pulping process with a TCF bleaching sequence. Process concepts were developed for each of these processes based on technology evaluations for the major areas. Order-of-magnitude capital cost estimates and manufacturing cost estimates were developed, and financial analyses were carried out to determine the economics of the processes.
