关于木薯渣生产酒精,“元芳”你怎么看?

       近期,不少业界人士和企业从废物利用、节约成本和环保等的角度考虑和分析,再次重提木薯渣生产酒精的问题,对此,“元芳”你怎么看?!
      “元芳”:大家的想法和意愿是好的,但现实却很无情。关于木薯渣生产酒精,其实已是了无新意的老话题,之前已有不少的研究分析和结论,这里不妨重述其中的一些观点和主要内容:1、关于木薯渣生产酒精在技术上没有任何问题(技术含量不高),不少的工厂已有成功的经验可借鉴;2、由于木薯渣的淀粉含量低,杂质多,成份复杂,使之工艺产酒率低、设备效能性差(可比情况下产能低)、能耗和材耗大、产品质量不稳定……,总之,较之使用木薯干片或糖蜜作原料生产酒精其加工成本大幅度提高,产品质量有所下降;3、木薯渣的收集、贮存、运输或预处理(如,干燥)不容易,影响了数量供应、生产成本和大规模的工业化生产;3、在环保上,酒精废物比木薯渣更难处理,污染更大,治理成本更高。此外,在生产核算时,不应忽视木薯渣本身的成本(目前含水份85%左右的湿渣每吨的市场销售价格达到了150—200元/吨)。最终,业界主流人士的意见认为:用木薯渣生产酒精,在技术上完全没有问题,但在经济上则行不通。对此,想为者,不妨谨慎为要!(本文仅供参考)
