In modern refineries, fluid catalytic cracking (FCC) is a process by which refineries convert residual oils from the atmospheric and vacuum distillation columns into more valuable gasolines and middle distillates. Here, long-chain hydrocarbons are cracked using pulverized catalysts such as aluminum and silicates.
FCC devices produce a by-product - distillation bottom products like aromatic and high-viscosity oils, most often in the form of complex oil emulsions. However, such suspensions of oil products have their value and are used as feedstock for the production of bunker fuel (blended) by companding. FCC sludge can be recycled and used as refinery feedstock, and also marketed as a feedstock for pure carbon production or as refinery fuel.
The key to upgrading the FCC sludge to a higher quality product is the removal of catalysts such as aluminum and silicon and other ash forming elements. High speed disc separators from GEA are used to effectively remove these contaminants.
Cleaning with centrifugal separators from GEA showed a separation efficiency of 90% for particles smaller than 5 microns. The FCC sludge becomes a valuable product, which provides additional profit for the refinery.
健康快乐的奶牛是成功和可持续牛奶生产的关键。因此,保持奶牛健康是每个奶农努力的核心。奶牛的健康受到许多因素影响,例如根据奶牛个体需求进行适当喂养、良好的饲养条件以及新鲜的空气、水和光照。而且,挤奶方式对奶牛的健康状况也有很大的影响。GEA 因其“优质挤奶理念”而闻名,不断致力于进一步发展,并在动物健康和牛奶质量方面取得更好的成果。
各行各业都在努力实现净零排放目标,同时遵守严格的脱碳法规和立法。与此同时,公司必须平衡日益增长的质量、产品开发和工艺优化需求,此外,还必须努力提高盈利能力。应对这一挑战需要采取 GEA 提供的协作和整体方法。
咖啡、可可、牛奶、肉类、鱼类和蛋类 - 这些日常主食在很大程度上依赖集约农业。随着新食品技术的兴起,我们有了更多可持续的替代品。我们采访了 GEA 液体、发酵和灌装部门的高级副总裁 Reimar Gutte 博士,探讨其中的可能性和政策。
