Medium Consistency Oxygen Delignification Performed with a Hydro Dynamics Controlled Cavitation Reactor, 2005 Engineering, Pulping & Environmental Conference

PressWeb.jpg

A U.S. mill has conducted a pilot scale medium consistency oxygen delignification (MCOD) trial incorporating a Hydro Dynamics ShockWave Power™ Reactor (reactor) as part of an integrated delignification system. Delignification responses have been obtained for various operating conditions and multiple chemical charges. Delignification levels of 35% or more were obtained for hardwood pulp. The trials were designed to determine potential operating costs, energy consumption, operational conditions and benefits associated with a low capital cost installation of this system into an existing washer line. Material and energy balances in conjunction with pilot plant and lab data have been used to predict potential net impacts of the MCOD system upon operating costs. The impact of the oxygen delignification operation upon pulp physical properties was also determined.
