text: The need for flexible process equipment has increased over the past
decade in the chemical industry. However, process equipment such as distillation
columns have limitations that significantly restrict flexible operation. We investigate
a segmented tray column designed to allow flexible operation. The design consists
of radial trays connected at the downcomer of each tray. Each segment can be operated
separately, but depending on the capacity of the feed stream, additional segments
can be activated or deactivated. The connection between the trays aims to transfer
liquid from one stationary segment to the adjacent inactive segment, thereby reducing
the time required for the start-up process. In a case study on the separation
of methanol and water, we perform dynamic simulations to assess the reduction
in the start-up time of inactive segments. The results confirm the advantages
over standard tray designs. The segmented distillation column is a step towards
improving the flexibility of separation operations.

text: The chemical industry has to deal with increasing uncertainties regarding
the boundary conditions of their production processes. On the one hand, uncertainties
affect the availability, quality, and prizes of raw material and energy. On the
other hand, the demand side is affected by increasing volatilities in product
demand and increasing requirements for product variety. These changing boundary
conditions lead to higher needs for flexibility in production processes of the
chemical industry. Within this article technical solutions for an enhancement
of different forms of flexibility are presented for production concepts and apparatus
concepts, respectively. The latter focuses on unit operations for the separation
of gas–liquid mixtures. This includes a review regarding transformable, modular
production processes and a classification of their field of application. Additionally,
concepts for named unit operations on different scales are presented and discussed.
The presented concepts are also classified with respect to the different types
of flexibility.
