    摘要： A filtration device includes a continuous first unit including a first membrane that separates a liquid into first permeated and non-permeated liquids, a first adjuster that adjusts a flow rate of the first permeated liquid to be substantially constant, and a first liquid scale that detects a liquid amount, a second unit including a second membrane that separates another liquid into second permeated and non-permeated liquids, a second adjuster that adjusts a flow rate of the second permeated liquid to be substantially constant, and a second liquid scale that detects another liquid amount, a first controller that controls the liquid amount in the first storage tank based on measurement values from continuous two first units or from the continuous first and second units, and a second controller that controls the another liquid amount based on a measurement value from the second unit.

    摘要： In alternative embodiments, provided herein are methods and industrial processes for generating high purity (high alpha cellulose) pulp from lignocellulosic feedstocks, comprising directly contacting a lignocellulosic feedstock with a system comprising a super critical or near-super critical fluid or mixture of fluids, whereby the partial pressure of the system provides for the alcoholysis, hydrolysis or a combination thereof of the feedstock at reduced temperatures and pressures, followed by an upgrading step wherein a low-purity cellulosic material generated in the super critical or near-super critical reaction step is treated with an alkaline solution. Also provided herein are systems and methods for producing a high purity cellulose material using reduced amounts of alkaline material.
