Reactors, packed columns, tray columns, heat exchangers, separators, crystallizers, pumps, compressors, pipes and so far – all these components have to be checked for suitability, designed, and constructed so that they can be properly operated in the process.
Process equipment could be both too small or too big. Specifying a minimum size and adding a safety factor alone is not enough. There rather is an operating range where the equipment can be reliably operated.
To find out where this operating range is and to design the equipment in such a way that it can be reliably operated at both the minimum and the maximum capacity – this is the expertise of Siemens EC. Or an existing equipment can be refurbished so that it can still be used after a capacity increase.
But this is still not all! Often, constructional details of the equipment’s interior are vital, e. g. distributors and collectors or the design of head and sump in case of packed columns.
Our approach ensures a fast and cost-effective equipment design. The simulation provides us with the load profile of the equipment; our self-developed CAPE system automatically transfers the data to the respective design or rating tool. There, the operating data of the equipment are compered with the design rules derived from literature, vendor information and own experience.
The constant observation of technical literature, the membership and participation in expert committees and a close vendor contact ensure that our design tools are always up to date. Due to our vendor-independency, we are able to recommend the very best equipment for your application.
Heating, cooling, evaporating, and condensing fluids are common procedural unit operations in chemical and pharmaceutical plants. We have long-time experience in designing, rating, and optimizing several kinds of heat exchangers, including evaporators and condensers.
Distillation is the most researched thermal separation technology and mostly used in industrial scale. The ongoing development of column internals (trays, random and structured packings, distributors and so far) allows for the geometric optimization of distillation columns, the improvement of product qualities, and the saving in operating costs.
The reactor is the heart of a chemical plant. Yield, conversion and productivity of the reactor define the structure and dimensions of the downstream separation processes and recycle streams. It lays the foundation for the economic feasibility of the whole process.
The modular set-up of membrane processes allows for an easy adaption to the scale of a separation task. Due to their variety, membrane processes offer a broad range of applications, also in process industry.
The crystallization allows for the separation of components with very high purities. Even enantiomers can be separated in some cases by utilizing fractionating crystallization. We monitor crystallization processes online in order to optimize operating parameters and to obtain reproducable crystals.
Mixing and stirring
The main task of reaction technology is the design of reactors. The mixing of the reaction partners and hence the design of stirrers and mixers are an important part thereof. The type of reactor, mode of operation and operating conditions must be determined as well as kinetics and heats of reaction.
In many different chemical processes, there are mixtures of two (or more) phases. The technical separation of those phases is mostly done with continuously operated separators.
