OptimEXT solutions are designed around Sulzer proven extraction technologies, especially around the well-known Kühni™ agitating column. These are combined with Sulzer’s high-performance distillation units to efficiently recover and recycle solvents, transforming challenges into opportunities.
OptimEXT liquid-liquid extraction solution is suitable for any facility that includes a liquid-liquid extraction step or is exploring solvent-based separation to improve process efficiency. Built on Sulzer’s highly efficient Kühni™ column technology, OptimEXT offers exceptional mass transfer performance with low solvent inventory, achieving up to 99.5% recovery efficiency and to ppb-range residue even in challenging feeds.
The system is already proved in many industries:
-
Refining & Petrochemicals: sulfur, PAHs, BTX, PCA, asphaltenes, phenols
-
Hydrometallurgy: recovery of cobalt, nickel, rare earths, uranium, copper
-
Battery & Energy Materials: lithium, manganese, black mass recycling
-
Wastewater Treatment: recovery of phenolics, amines, sulfonic acids, and carboxylic acids from industrial effluent
-
Pharmaceuticals & Fine Chemicals: solvent purification, API recovery, impurity removal
-
Natural Extracts: flavor and fragrance isolation, preservation of heat-sensitive bio-actives
-
Agrochemicals & Specialty Chemicals: separation of reactive intermediates or solvent recovery

蒸馏虽然是一种广泛应用的分离方法，但对于共沸物、沸点相近的混合物或热敏性化合物，其能耗较高且效率较低。OptimEXT 采用液液萃取技术克服了这些局限性，能够在较低温度下进行选择性分离，通常可节省高达 50% 的能源。这不仅能保证敏感产品的完整性，还能提高整体工艺效率。
OptimEXT 在以下情况下尤其具有优势：
-
分离无法通过常规蒸馏方法打破的共沸物
-
处理高温下会降解或聚合的产品
-
以较低的能耗回收有价值的溶剂
-
降低蒸馏塔负荷及相关运行成本
-
在化学结构相似的化合物存在的情况下提高选择性
-
混合澄清器占地面积大，且在大规模应用中往往难以保持工艺稳定性。相比之下，OptimEXT 采用 Kühni™ 搅拌塔，具有高回收率、即使在进料成分变化的情况下也能保持稳定的性能，并且其紧凑的模块化设计更易于集成到现有工艺中。OptimEXT 的一些已证实优势包括：
-
溶剂用量减少高达 70%，从而降低运营成本。
-
紧凑的模块化设计可减少 60% 的占地面积，从而降低资本支出。
-
密封系统确保更安全、更清洁的运行，并将排放降至最低。
-
在各种进料条件下均能保持稳定、高效的性能。
