GEA 针对可持续水泥生产的空气清洁解决方案
现在，人们都是在现代化水泥厂中使用熟料煅烧工艺通过连续干燥过程将天然原材料制成水泥。这种能耗高、温室气体排放量也高的生产可以达到每天 3,000 到 10,000 吨的产量。
GEA 技术可以最低的能源成本将粉尘排放量降至低于可追溯水平。即使使用净气机实现可靠的脱硫也完全不是问题。
我们创新的净化气体 SCR 技术能够保证从窑排出的气体的 NOx 含量远低于现有的环境法规要求，且完全不会泄漏氨。废热回收是我们的创新技术之一，我们凭借这项技术可以回收预加热器塔和/或熟料冷气机中的热能，并通过 ORC 设备生产电能。GEA 技术不仅支持降低环境足迹，还有助于大幅降低运营成本。
在水泥生产行业中，我们为以下应用领域提供技术：
粉尘控制
我们的 ECOpuls 袋式过滤器代表低于可追溯水平的粉尘排放量、彻底的袋式净化（延长寿命期）以及能耗的大幅降低。
NOx 控制（NOx 去除）
我们的净化气体选择性催化反应器 (SCR) 可以最低的氨泄漏和高可用性实现最高的转化率。
脱硫（SOx 清除）
我们的湿式净气机设计使用生料作为试剂，并制定了卓越的石膏格式以供在精轧机中使用。
废热回收
我们的废热回收系统结合了经过考验的 ORC 技术和创新的热交换器设计，可以回收水泥生产过程中的大部分废热能。我们最新的设备可以生产逾 4 MW 的电能。

Catalytic gas cleaning
Selective Catalytic Reduction (SCR) diminishes post-combustion NOx by reacting with urea or ammonia to produce nitrogen and water.
CO2 saving processes
CO2 savings come from reducing fossil fuel demand either by increasing energy efficiency or by separating CO2 from flue gas streams along with long-term fixation in valuable products or storage. GEA offers products and processes for all relevant stages.
Cooling, quenching & conditioning
The Rapid Cooling or Quenching of gas streams is used in several essential applications in the process industries.
Sorption
GEA offers three (“wet”, “semi-dry” and “dry”) Sorptive Processes for Flue Gas Desulphurization (FGD) and for other acidic compounds.
