来自废弃物...
废油通常存储在油污塘中，它们来源于油罐清洁过程、滤器反冲过程、炼油过程的废弃产物、泄漏或“丢弃”（传统油处理设施的废弃物）。它们是由油、水、各种化学品以及大大小小各种固体颗粒物组成的混合物，因此其各种成分可能会有很大差异。
... 到利用
第一步是对废油进行预处理。为此，要将油温升高到处理温度，并添加相应的化学品（例如破乳剂）来分裂乳化液，之后在特殊的混合器中进行均匀的搅拌。这是确保整个处理过程尽可能稳定的重要因素。无论混合物中的水和固体物质含量是否较高，也无论它的粘度是否较高，GEA 提供的高性能卧螺机都能将固体物质分离出来；如果采用三相卧螺机，它们还能同时将水从油中分离出来。我们的卧螺机能自动调整差速，使其适应变动的进料条件，从而始终保持最佳的分离效率。在后续的精细处理阶段，碟片式离心机能从油中分离出残留的水和极细的颗粒物。回收的油现在已符合标准精炼要求，可与正常的原油混合在一起做进一步的炼化处理。
处理卧螺机排出的水相是由自清式碟片分离机来完成的。它们通过除去极细小的沉淀物以及将残留的油含量降低到允许的限值甚至更低（通常是不超过 15 ppm）对水进行“精制”处理。通过这种方式能可靠地满足现有的环保要求，并且能以环保的方式对水进行处置。
按 ATEX 标准防爆设计
符合 ATEX 防爆区域 2 或 1 规定的防爆产品可在所有相关的处理过程阶段中提供最高的安全性。采用我们的惰气覆盖保护原理，被归类为危险品的物料也能在高于其闪点的温度下被加热并可靠地处理。
完整的系统和移动解决方案
作为废油处理方面出色的合作伙伴，我们提供用于处理油和水的完整系统，包括整个控制设施。有各种规模的处理线并且可以定制，以满足客户的具体需求。此外，所有设备都可以安装在集装箱中，因而可移动使用。
Single stage treatment
For feedstock material that can be efficiently processed through dewatering and simultaneous oil and water separation, GEA's 3-phase single-stage decanter centrifuges are the preferred solution. These centrifuges can handle high solid content achieving maximum dewatering and clarification in one stage, making them ideal for easier slop oil treatment requirements.

Double stage treatment
In cases where the feedstock is more challenging to treat or higher oil quality is required, GEA's double-stage treatment process becomes more viable. This involves using 2-phase decanter centrifuges followed by high-speed disk stack centrifuges. The disk stack machines process the decanter centrate phase, separating ultra-fine particles and maximizing water removal. This results in a high-quality oil product that can be merchandized similarly to crude oil.
