Abstract

The productions of vegetable oil and methyl esters of vegetable oil lead to the generation of a lot of by-products. The purpose of this work was to study an alternative solution for a profitable use of vegetable oil by-products: anaerobic digestion. The potential for anaerobic digestion of 24 by-products was studied. The results show that most of oil by-products had a good capacity for anaerobic digestion. Then, the effects of the addition of oil by-products on the behavior of one reactor treating a mixture of grass, cow manure and fruit and vegetable waste and another reactor treating household waste were investigated. Most of the by-products tested improved significantly the production of methane indicating that the addition of by-products from oil production could represent a significant financial earning for the digester operators.Discussions are in progress involving oil producers and biogas plant operators to assess the opportunity of supporting the addition of by-products from oil refining in their facilities. A first evaluation of the costs and potential benefits of by-product treatment was performed. These costs should be reviewed in line with the increased development of anaerobic digestion and the expected benefits due to the digestion of by-products.
通过甲烷化对炼油副产品进行定价
植物油和植物油甲酯的生产会产生大量的副产物。本工作的目的是研究一种可替代的解决方案,以有效利用植物油副产品:厌氧消化。对24种副产物的厌氧消化潜力进行了研究。结果表明,大部分油脂副产物具有良好的厌氧消化能力。在此基础上,研究了油脂副产物对处理草粪、牛粪和果蔬垃圾的反应器和处理生活垃圾的反应器性能的影响。测试的大多数副产品都显著提高了甲烷的产量,这表明石油生产副产品的加入可以为沼气池运营商带来可观的经济收入。石油生产商和沼气厂经营者正在进行讨论,以评估在其设施中支持增加炼油副产品的机会。对副产物处理的成本和潜在效益进行了首次评估。这些成本应根据厌氧消化的发展和副产品消化的预期效益进行审查。
