2 Methanl Recvery Systems Methanl Recvery fr bidiesel is an imprtant part f the entire bidiesel prcess and invlves the highest cst f peratin fr a bidiesel plant. Only abut half f the methanl used is actually cnsumed in the transesterificatin prcess leaving the rest in the finished bidiesel and glycerin. With tday s high methanl csts, bidiesel prducers simply cannt affrd t thrw away half f the methanl they purchase. Als, with everyne nw striving fr ASTM-cmpliant bidiesel, leaving methanl in finished bidiesel has anther bad side effect, it will fail the ASTM Flash Pint test. Nw there is a slutin fr recvering yur unused methanl SRS Engineering s high-purity methanl recvery systems. Unlike 1st generatin vacuum based systems that suffer frm lw recvery rates, water cntaminatin, glycerin, r bidiesel carry ver in the recvered methanl, SRS s true fractinal distillatin clumns efficiently recver >99.9% f all unused methanl, returning it clean and dry t yur bulk methanl tank at >99.9% purity. This results in n wet methanl and n ffsite reprcessing csts. In fact yur recvered methanl is ften f a higher purity than the new methanl yu purchase. SRS Engineering emplys bth single and dual clumn designs in the Bidiesel prductin prcess t maximize energy use and efficiencies. The SRXC-Series - Remves Methanl frm the Glycerin stream The ASV-Series - Recvers excess Methanl fr cleaner unwashed fuel The SRXC-Series Remves Methanl frm Glycerin Stream 99.9% Purity range Prvides Glycerin stream with less than 0.1% Methanl cntent (Nn-hazardus) Autmatic self adjusting cntrl system fr variable parameters Skid munted n a galvanized steel tubular frame Prvides cntinuus peratin Pre-wired,pre-piped, and tested prir t custmer delivery Jeffersn Avenue Murrieta, CA Phne: Fax:

3 The SRXC-Series is a cmpletely autmated methanl recvery/purificatin system fr recvering methanl frm crude glycerin prduced in the bidiesel prductin prcess. The SRXC system is designed t prcess the glycerin stream prviding a very dry methanl with a purity exceeding 99.5%. The SRXC emplys a specially designed fractinating clumn with a reflux stream is used t separate the materials in a cntinuus mde n a 24-hur basis fr bidiesel plants prducing frm 500,000 t ver 100 millin gallns per year. The SRXC2-Series The SRXC2-Series is a mre advanced distillatin clumn used mst cmmnly with larger bidiesel refineries. It incrprates all f the same functinalities f the single clumn designed SRXC but prvides a 40-50% reductin in peratinal csts. The ASV-Series Remves excess methanl and water frm the unwashed bidiesel. Reduces typical wash times assciated with dry/wet washing Reduces dry wash cnsumables and/r prvides lnger wear life f In materials Recvers the methanl fr additinal purificatin Prevents lss f methanl assciated with washing prcess The ASV-Series clumn is a cmpletely autmated methanl and water extractin system used fr the bidiesel stream leaving less than 0.05% methanl r water in the unwashed fuel. NOTE: The ASV des utilize vacuum but it shuld nt be cnfused with a basic "Vacuum Dryer" as such systems typically have carry ver f bidiesel r glycerin if used fr that purpse; the ASV des nt have any carry ver. The ASV is a specially designed clumn perated in a cntinuus mde n a 24-hur basis fr bidiesel plants prducing frm 500,000 t ver 100 millin gallns per year Jeffersn Avenue Murrieta, CA Phne: Fax:
