Sulzer Heat Exchangers and Reactors
Static mixing where heat transfer meets viscous media
Heating, cooling and reacting viscous, laminar-flowing media is a challenge for conventional heat exchangers: poor radial mixing creates wide temperature and residence time distributions, hot spots and product degradation. Sulzer’s SMXL™ static mixer heat exchangers and SMR™ mixer reactors solve this by integrating proprietary mixing elements into the heat transfer geometry, delivering uniform temperature, plug-flow behavior and precise control of highly exothermic or temperature-sensitive processes, without any moving parts.
What are static mixer heat exchangers and reactors
In laminar flow, heat moves from the wall to the core of the fluid by conduction only, so the center of a viscous stream stays cold (or hot) while the layer at the wall overheats and degrades. Sulzer’s static mixing elements continuously split, shear and recombine the stream, transporting fluid from the core to the wall and back. The boundary layer is renewed permanently and the whole cross-section is kept at a uniform temperature.
The SMXL™ heat exchanger places these elements in a jacketed monotube or in the tubes of a multitube exchanger. The SMR™ mixer reactor goes one step further: the mixing elements themselves are tubes carrying the heat transfer fluid, providing a very large heat exchange surface directly inside the process flow. This makes the SMR™ the reactor of choice for continuous polymerization and other reactions where heat must be removed or supplied exactly where it is generated.
How static mixer heat exchangers work
深入了解精馏过程的各个步骤,揭示实现液体混合物精准分离的原理
1
Laminar feed
The viscous process stream (polymer melt, solution or reacting mixture) enters the tube or tube bundle in laminar flow, typically at low Reynolds numbers where conventional heat exchangers perform poorly.
2
Splitting and recombining
Proprietary SMXL™ mixing elements, crossed bars arranged in successive, rotated layers, divide the stream into many partial streams and recombine them, creating intensive radial mixing without turbulence.
3
Boundary layer renewal
Fluid is continuously transported from the core to the heat transfer surface and back. The thermal boundary layer at the wall is renewed permanently, so the heat transfer coefficient is several times higher than in an empty tube.
4
Heat exchange
Heat is transferred through the jacket or tube wall (SMXL™), or through the mixing elements themselves, which are tubes carrying the heat transfer fluid (SMR™). Temperature is controlled precisely along the whole length of the unit.
5
Uniform outlet
The product leaves with a homogeneous temperature profile and a narrow residence time distribution close to plug flow, with no hot spots and no stagnant zones, ready for the next process step or reaction stage.

精馏是一种基础性的分离工艺,用于将液体混合物提纯并分离为各个组分。该过程利用不同物质的沸点差异实现精确分离,因此在从石油化工到制药等多个行业中都至关重要。
核心原理: 将液体混合物加热至部分汽化,并对生成的蒸汽进行冷却冷凝,以分离不同挥发性的组分;通过多次循环,实现目标产品的高纯度。
选择哪种方式取决于生产规模和工艺灵活性需求。间歇精馏以固定批次物料进行顺序处理,能够提供多产品生产装置所需的高度灵活性,并可结合我们的 Excelot™ 解决方案实现优化设计。相比之下,连续精馏是一种稳态运行工艺,适用于大规模、连续化生产。苏尔寿通过 DistilCare™ 解决方案对连续精馏过程进行优化,并采用 MellapakPlus™ 等高性能塔内件,以确保稳定的产品质量和最大的处理能力。
变压精馏是打破共沸物最有效的无溶剂方法。通过在不同压力下操作两根塔,可以改变共沸点,从而在连续循环中实现高纯度分离。与需要外部化学试剂的传统共沸方法相比,该方法结合了苏尔寿先进的热集成技术,显著降低了运营成本和总体碳足迹。
反应精馏将化学反应和热分离集成于一体。这种集成方式尤其适用于酯化等平衡限制反应。我们采用专有的Katapak™催化填料,可在反应的同时去除副产物,从而移动平衡以提高产率。由于无需单独的反应器和下游纯化设备,因此可降低资本支出 (CAPEX) 和运营支出 (OPEX)。
我们的GT-DWC™技术将传统的多塔序列整合到单个塔体中。这使得在单个装置内即可实现三馏分混合物的高纯度分离。通过减少再沸器和冷凝器的数量,DWC 技术显著降低了资本投资和能耗,同时大幅减少了设备占地面积。
作为“精馏2.0”计划的一部分,苏尔寿推出了VoltaSplit™技术。该技术通过以高效机械蒸汽再压缩(MVR)取代化石燃料蒸汽再沸器,实现了精馏过程的电气化。结合先进的热泵集成技术,该技术通过减少热分离过程中的范围1排放,为实现净零排放提供了直接途径。
为了优化工厂性能,我们采用先进的气液分离器,例如KnitMesh™除雾器和Schoepentoeter™ Plus入口装置,用于去除蒸汽管线中的液滴及其后方的杂质(例如固体、较重的组分会导致泛黄,甚至金属离子等)。对于互不相溶的液体,我们的DC Coalescer™和Dusec Plus™技术能够打破初级/次级分散体系,并在工艺设备中长时间沉淀。这些解决方案可确保获得高纯度相,最大限度地减少物流污染,并降低内部循环,从而实现更高效的分离。
