Discussion on Process flow diagram for biomass

Here we investigate the technical feasibility of converting the paper mill sludge into fuel ethanol. Removal of mineral fillers is involved by using the pretreatment either chemical otherwise to determine their effects mechanical fractionation on cellulose hydrolysis as well as fermentation to ethanol.  We present here the result from the paper mill sludge the fillers content removed. Here we describe the process flow diagram here as well as also explain the process;

As we demonstrate about the material and method of this process flow diagram. Here we take the sample of paper mills sludge. These paper mills sludge go to the other section that is de-ashing of primary sludge. This section is used for the removal of the primary sludge. Then it is filtered and the solid residue goes to the enzymatic hydrolysis process. This process performed at 50 degree Celsius. This experiment of hydrolysis was run in triplicate. After that the solids-free sugar solution was stored until the fermentation, enzymatic hydrolysis performed, for the fermentation experiment. The fermentation process is used for the production of biomass or ethanol. After the fermentation process distilled the ethanol and the waste stream is also released

Here we discuss about the N-VIRO Biodry Process. In this process to dry the sludge heated air is used or by-products manure mixed with alkaline. In a rotary drum dryer drying is done. Compared to the conventional process less by-products is used for disinfection since part of the required heat from the dryers comes. Final product could be better controlled final solids content. In particle size final product is more uniform. Sludge/ fly ash entering the rotary drum bio dryer. Modification of the BioDry process is known as N-Viro fuel process. Consequently we call it as the modern biodry process. As an additive fly ash power plant used in this process. From the Biodryer the exhaust gases contains for NO_x reduction ammonia that could be used. Because of the Volatile nature of sludge traditional Sludge dryers are prone to fires as well as explosion. These operational problems are not faced by Biodryer. Above air-drying temperatures research showed that the addition of mineral by-products to raise the sludge raised ignition.
