Process Development Unit for biorefinery processes





    Namn på nationell/internationell infrastruktur som denna infrastruktur tillhör

    Shares some equipment with the Membrane research infrastructure.


    The Process Development Unit (PDU) is a collection of unit operations in bench and pilot scale for bioethanol and biorefinery research. The PDU have capability for pretreatment of biomass, enzymatic hydrolysis and fermentation. The main difference between the research done in laboratory scale (typically 25-400 g dry matter) and the PDU research (typically 2-20 kg dry matter) is the possibility to scale the results obtained in the PDU to pilot plant scale (typically 1 ton/day). At the heart of the PDU three pretreatment reactors reside: two batch reactors and one continuous (for acidic, neutral or alkaline conditions). The batch-reactor systems are based on an in-house design, which has evolved over the years through cooperation with industry. The reactors has 4 and 10 l working volume enabling treatment of 300-1000 g of raw material per batch. The continuous pretreatment system from AdvanceBio Systems has a capacity of 10-20 kg/h depending on raw material. For enzymatic hydrolysis and fermentation the PDU is equipped with fermentors ranging in sizes from 5 l (yeast cultivation) to 100 l. The PDU also have filtration, membrane filtration and distillation capabilities in batch and pilot scale.
