Abstract

COMPRESSOR DE ALTA PRESSãO E MéTODO DE FORMAçãO DE POLPA COM EXPLOSãO DE VAPOR. A presente invenção refere-se a um método de formação de polpa com explosão de vapor incluindo: impregnar um material de alimentação de biomassa celulósico em um recipiente de reator pressurizado, descarregar o material de alimentação impregnado do recipiente para um compressor de alta pressão, elevar a pressão do material de alimentação no compressor, descarregar o material de alimentação pressurizado do compressor para um conduto acoplado em uma válvula de descarga, reduzir rapidamente a pressão do material de alimentação pressurizado quando o material de alimentação passa através da válvula de descarga e polpar o material de alimentação pela expansão do fluido no material de alimentação durante a rápida redução de pressão.HIGH PRESSURE COMPRESSOR AND STEAM EXPLOSION PULP FORMATION METHOD. The present invention relates to a method of steam blast pulping comprising: impregnating a cellulosic biomass feedstock into a pressurized reactor vessel, discharging the impregnated feedstock from the vessel to a high pressure compressor, raising the pressure of the feedstock into the compressor, discharge the pressurized feedstock from the compressor to a duct coupled to a discharge valve, rapidly reduce the pressure of the pressurized feedstock as the feedstock passes through the discharge valve and pulp the feed material by expanding fluid into the feed material during rapid pressure reduction.
