Liebe Leserinnen und Leser, die Deutsche Gesellschaft für Membrantechnik (DGMT) beschäftigt sich seit ihrer Gründung intensiv mit Anforderungen, Techniken, Verfahren, Entwicklungen und zukünftigen Strategien rund um die Membrananwendung in allen Industriezweigen. So stand in diesem Jahr die traditionelle Kassler Tagung unter dem besonderen Motto „25 Jahre DGMT – Membrantechnik: gestern, heute und morgen“. Die zusammen mit der DECHEMA/VDI Fachgruppe „Membrantechnik“ organisierte Tagung Membrantechnik fand gemeinsam mit der Jubiläumsfeier zum 25-jährigen Bestehen der DGMT statt. Dieser Rahmen bot Gelegenheit, in Gemeinschaft auf die Errungenschaften der vergangenen Jahre anzustoßen und die Weichen für die Zukunft zu stellen. Wir als DGMT blicken mit Stolz auf ein Vierteljahrhundert zurück, in dem unsere Gesellschaft maßgeblich zur Entwicklung und Verbreitung der Membrantechnologie beigetragen hat.

Mit den vielfältigen Beiträgen wurde deutlich, dass die Membrantechnologie seit Jahrzehnten eine wesentliche Schlüsselrolle spielt und insbesondere in Hinblick auf ökologische und gesellschaftliche Zukunftsthemen wie Energieerzeugung, Wasser- und Ressourcenknappheit und Folgen des Klimawandels weiterhin spielen wird. Wir konnten ein vielfältiges Programm gestalten, das sowohl einen Rückblick auf bedeutende Meilensteine als auch einen Ausblick auf zukünftige Herausforderungen und Chancen der Membrantechnik bot.

In dieser Ausgabe der Chemie Ingenieur Technik geben einzelne auf der Tagung präsentierte Beiträge einen Eindruck von der Vielfältigkeit der Themengebiete, die von der Materialentwicklung CO2-responsiver Polymere über die Entwicklung von Methoden für die Schadensfallanalyse bis hin zur Untersuchung von Ablagerungsbildung in der Membrandestillation reichen. Einblicke in die praxisnahe Entwicklung erhalten Sie im Beitrag über die Untersuchungen der Kopplung von MBR-Technik mit nachgeschalteter Ozonung für die erweitere Abwasserbehandlung.

Wir hoffen, dass diese Veröffentlichungen die vielfältigen Anwendungs- und Themenbereiche der Membrantechnik verdeutlichen und das Bewusstsein für die Bedeutung der Membrantechnologie in der Zukunft schärfen sowie neue Impulse für weitere Forschungsarbeiten und Anwendungen setzen. Wir wünschen den Leserinnen und Lesern viel Freude bei der Lektüre!

Model-based process design and operation involves here-and-now and wait-and-see decisions. Here-and-now decisions include design variables like the size of heat exchangers or the height of distillation columns, whereas wait-and-see decisions are directed towards operational variables like reflux and split ratios. In this contribution, we describe how to deal with these different types of decisions in a multicriteria framework, offering an adjustability for the wait-and-see variables while at the same time respecting optimality guarantees on process key performance indicators (KPIs).

Phenol is an important chemical commodity utilized for several applications (e.g., polycarbonates, epoxy and phenolic resins, nylon). Its production starts from benzene and propylene and is based on a series of reaction steps. Among them the acid cleavage of cumyl hydroperoxide is characterized by the high reaction rate of the main reaction, together with a number of side reactions. During the 1980s a thorough kinetic study has been carried out by the researchers of Montedipe S.p.A. This activity led to the development of a comprehensive kinetic model including 14 differential equations and 15 parameters, then utilized for process operations and unit design. A review of the strategy adopted for the experimental activities is provided along with a discussion on model identification and parameter estimation.a

苯酚是一种重要的化学商品,用于多种用途(例如聚碳酸酯、环氧树脂和酚醛树脂、尼龙)。它的生产从苯和丙烯开始,并基于一系列的反应步骤。其中过氧化cumyl酸裂解的特点是主反应反应速率高,同时伴有若干副反应。在20世纪80年代,Montedipe S.p.A的研究人员进行了一次彻底的动力学研究。这项活动导致了一个包括14个微分方程和15个参数的综合动力学模型的发展,然后用于工艺操作和单元设计。对实验活动所采用的策略进行了回顾,并讨论了模型识别和参数估计

Machine learning (ML) enables the development of powerful methods for predicting thermophysical properties, but technical barriers like cumbersome implementation in established workflows hinder their application in practice. With MLPROP, we provide a web interface to predict thermophysical properties with advanced ML methods. MLPROP includes models for predicting the vapor pressure of pure components (GRAPPA), activity coefficients and vapor-liquid equilibria in binary mixtures (UNIFAC 2.0, mod. UNIFAC 2.0, and HANNA), and a routine to fit NRTL parameters to the model predictions. MLPROP will be continuously updated and extended and is accessible via https://ml-prop.mv.rptu.de/. The source code of all models is available as open source, which allows integration into existing workflows.

An integrative resource efficiency management approach supports small and medium-sized enterprises (SMEs) in the chemical industry in systematically embedding resource efficiency and circular economy principles. A structured management approach combined with a central responsibility is a key success factor. A digital platform, a practical evaluation model, and technology scouting further facilitate implementation. Further responsibilities in the individual company departments, data availability, and goal tracking are specifically addressed, enabling companies to better exploit both ecological and economic potential.

Production key figures of mineral processing plants, often designed as circuits with recirculation of material, are subject to a high number of influencing factors. In order to set up plant operation in an optimal way, identifying factors with high significance is important. In this study, an artificial neural network is employed as an additional tool for such processing plant audits by means of feature importance analysis. The presented method is applicable independently of the specific plant design, wherever sufficient process data is available. Furthermore, specific outcomes of the analysis of an exemplary potash compaction circuit are discussed.

Gradient-Free Measurements of Catalyst Plates Using a Berty Reactor 用Berty反应器对催化剂板进行无梯度测量

A Berty reactor modification is presented allowing kinetic investigations of catalyst plates or thin-film catalysts. Due to the narrow and defined spacing and high residence times, DaII numbers below 0.001 can be achieved, excluding external mass transport. The reactor was tested in the methanol synthesis with wash-coated catalyst plates. Reaction parameters were varied over a large range proving the versatility of this system. The obtained activation energies for MeOH and CO formation are in good agreement with similar systems. At high pressures, the stirrer can homogenize the reaction mixture quite easily; above 500 rpm no effect of the stirrer on the performance can be observed. Even at ambient pressures, homogenization can be achieved, however, only at very high stirring speeds exceeding 4000 rpm.

提出了一种改进的Berty反应器,允许对催化剂板或薄膜催化剂进行动力学研究。由于间隔窄且确定,停留时间长,可以实现低于0.001的DaII值,不包括外部质量输运。对该反应器进行了水洗包覆催化板甲醇合成试验。反应参数在很大范围内变化,证明了该系统的通用性。所得的MeOH和CO生成活化能与类似体系的结果吻合较好。在高压下,搅拌器可以很容易地使反应混合物均质;转速超过500转时,搅拌器对性能没有影响。即使在环境压力下,均质化也只能在超过4000转/分钟的高搅拌速度下才能实现。
