In this paper it has been presented the results about the study with high pressure steam schemes for the energy integration of a sugar mill with a pulp paper factory. The hypothesis for the integration is that it is possible to produce heat and electricity for both factories with the biomass of the sugar cane. This study includes the diversification of the production whit an ethanol factory for the pulp. The by bibliography, energy, material and cost balances are the main subjects for the best alternative of integration with high pressure schemes. The scheme with 61 ata and 440 °C was the best technically but not in the economic sense. [ABSTRACT FROM AUTHOR]

This work is part of a sustained I make an effort to increment the competitive of the companies producers of paper for corrugation also named paper midium, utilizing for it- of form alternating pulps, between the which they have possibilities of utilization the recycled paper and the fibers gotten with the process organosolv (etanol-water) starting from the trash of cane of sugar, that is a by- product of the fabrication of sugar. The investigation was carried out with support of an experimental design of grating simple. The outputs that were gotten show that a combination of the 33% of Old Corrugated Continer (OCC) and 67% of fiber organosolv (1,5% of flat and high level of alcohol) with Number of kappa 84,5, it has similar outputs to the Flat Crush Resistance Lab-corrugated of paper (CMT) (140,58 N ó 31.6 lbf of industrial paper), to the of a combination of 65% of OCC with 35% of Organosolv Pulp (1,5% of flat with low level of alcohol), with Number of Kappa of 78,5.
