The seminar aimed to study three plants do, to produce ethanol. Manufacturing process and technology to produce ethanol for Thailand, a country
.The raw materials used to produce. The most often used cassava, sugar cane and molasses. As the main raw material in production. From the study of the process of ethanol. And with the raw materials used when thinking on ethanol production, 150000 litres per day) consists of 1 cassava in raw material preparation to use of 350-370 tons / day, there will be some moisture and must have 13-16% flour 65% (well. Basis) water use in the process 1 000 - 1,,500 tons / day, preparation of raw material and mixed with water to hot water mixer concentrations around 17-18% Total Solid starch hydrolysis sugar mainly used digestion and fermentation. The sub Liquefaction with enzyme (alfa-amylase) 95-100 ° C 2 hours.(Glucoamylase) 55 - 65 ° C take 24 hours fermentation using continuous fermentation by yeast Saccharomyces cerevisiae. Efficiency of about 90-91% (less than molasses due to the loss of efficiency in the sub).Dehydration 30 - 32 ° C take 48 hour efficiency about 96 distillation.5% technique using the permeability Membrane efficiency separation mixture solution through membrane about 99.5%, water slop, about 1 400-1 600 cubic meters, per day. The TS 5-7% value, COD 40 000-60 000 mg / L, and the BOD 15 000-35 000 mg / L,,,, 1 250-1 wastewater410 cubic meters per day). TS 4-5% value, BOD 35 000 ppm COD, and 50 000 ppm 2) use sugar cane molasses and
in the preparation of raw materials will need to use a quantity 540-550 tons / day. To the Tota, sugar 48-50%80°Brix ใช้น้ำในกระบวนการผลิต 1‚000-1‚300 ตัน/วัน การเตรียมวัตถุดิบและการผสมน้ำจะต้องการกำจัดสิ่งปนเปื้อน (Cadmium) ด้วย H2SO4 และ won ตะกอน after (may not have to do some technology about 25% dilute. ")Use of a continuous fermentation process by using yeast Saccharomyces cerevisiae efficiency of about 92% distillation and purification using distilled water. Dehydration cane 32-35 ° C take 16 hours, molasses 32-35 ° C take 30 hours.96.5% technique Membrane permeability performance isolation mixture solution through membrane about 99.5% water slop of,, 1 000-1 300 cubic metres per day. The TS 15% value, COD 100 000-150 000 mg / L, value, BOD 40, 000-70 000 mg / L bath waste contained, 1600 cubic meters per day). 10-12% TS value BOD 50 000 ppm, value, COD 150In the 000 ppm popular, cassava, sugar cane and molasses. As the main raw material in the production of ethanol, which has many advantages - drawbacks as follows 1) / cane molasses, advantages.Molasses is the production cost is low. The disadvantages are the process is more complicated than วัตถุดิบจาก flour and sugar, the slag formation in distillation column. The factory must stop walking machine to clean frequently.Which is difficult to remove color barriers. Problems in drainage into the natural water 2) cassava. Advantages are functions can reduce power use and cost up to 50% let bath no wastes of dark.The disadvantages are the release system. In addition to ethanol as the main raw material and also has a secondary raw materials, including CO2 DDGS (Dry distillers grains with solubles fuelcells ออยด์.) Yeast (Saccharomyces cerevisiae) and biogas
