Distillation is a common unit operation, which is used to separate or purify components in a feed stream. Flooding is a common abnormal process condition wherein the distillation column stops generating a separation, thus causing the quality of the top and/or bottom products to go off specification. The Rosemount 3051S Pressure Transmitter with Advanced Diagnostics can be used to detect incipie...

This paper reports the pyrolytic treatment of granulated scrap tires (GST) in a pilot distillation unit at moderate temperature (550°C) and atmospheric pressure, to produce oil, char and gas products. Tire-derived oil is a complex mixture of organic C(5)-C(24) compounds, including a very large proportion of aromatic compounds. This oil has a high gross calorific value (∼ 43 MJ kg(-1)) and N and...

The present thesis is motivated by chemical engineering: process simulation and optimization with a focus on distillation-based flowsheets. In this context, a process consists of a number of unit operations connected by streams. Such a structure can be represented by a so-called flowsheet. In general, the process should be designed in a way that certain engineering demands are fulfilled, e.g. p...

An important amount of work exists on the topic of optimal operation and control of batch distillation though it is still based on the assumption of an accurate process model being available. While this assumption is valid from a theoretical point of view, there will always remain the challenge of practical applications. Reinforcement Learning (RL) has been recognised already as a particularly ...

Soft sensors for the on-line estimation of kerosene 95 % distillation end point (D95) in crude distillation unit (CDU) are developed. Experimental data are acquired from the refinery distributed control system (DCS) and include on-line available continuously measured variables and laboratory data which are consistently sampled four times a day. Additional laboratory data of kerosene D95 for the...
