Durco Biodiesel Equipment (a division of Ascension Industries Inc.), recently announced a new range of生物柴油干洗与过滤系统that significantly reduce both process time and costs compared to traditional water or bubble washing techniques. The revolutionary new biodiesel systems were developed over the past two years from the company’s range of vegetable oil dry washing systems that have been proven in service since the 1970’s
迈克尔·杜瓦尔（Michael Duval）（一名DURCO过滤应用工程师）解释说：“新的生物柴油干洗和过滤单元的新系列使用新开发的剪切混合设备和镁硅酸盐添加剂，从而有效地从经过跨酯化的生物柴油工艺流中有效地吸附了所有不需要的液态相分量。2020欧洲杯下注官网接下来的过滤步骤（使用生物柴油过滤器按下或生物柴油压力叶过滤器技术）然后将纯化的甲基酯液体生物柴油与固体吸附剂分开，并将其澄清为高质量的生物柴油燃料。与传统的生物柴油洗涤系统（产生危险的液体废物流）不同，新洗涤过程的副产品是一个实心滤饼。
The new range of dry washing systems is suitable for biodiesel plants producing 1M gal/yr or considerably more, depending upon filtration technology chosen:
- Biodiesel Filter Press Technology (<10Mgal/yr, per filter unit, at temperatures up to 170oF)
- Biodiesel Pressure Leaf Filter Technology (typically >10M gal/yr or much higher, with essentially unlimited high temperature capability for enhanced biodiesel washing).
这些新的DURCO生物柴油干洗和过滤系统可以配置为使用手动，半自动或全自动操作的连续或批处理操作。它们减少了整体生物柴油的生产时间和成本，因为它们消除了对油/水乳液分离阶段或干燥阶段的需求。通过消除与传统洗涤设备相关的资本和维护，这也大大降低了生物柴油工厂的初创企业和运营成本。”2020欧洲杯下注官网
该公司最近宣布将两个交钥匙生物柴油干洗系统交付给美国生物柴油工厂：
- 目前，美国上层美国运行的第一个系统正在运行。这个特殊的生物柴油纯化和澄清单元每年能够干洗和过滤多达100万加仑的原油生物柴油。它由一个硅酸镁干洗罐和一个生物柴油级的杜尔科侧栏滤清器组成 - 该项目特别选择了该项目的资本成本低和运营的较低交付时间。
- The second system shipped to a Texas-based biodiesel manufacturing plant early last month. This automatic biodiesel processor consists of a mixing unit for dry washing the biodiesel and a Durco Biodiesel-Rated Filter Press for final filtration / clarification. It is designed for production of up to 4 Million gallons of high quality biodiesel per year.
