Process synthesis using block superstructure with automated flowsheet generation and optimization

Flowsheet optimization with implicit models and complex cost and size functions using Chemical Process Simulators

In this paper we address the synthesis and design of chemical processes using Chemical Modular Process Simulators – that include state of the art modelsincluding discontinuous cost and sizing equations. Equations are divided into ‘implicit’ ones which include all the equations in the process simulators with an input-output black box structure, and other third party equations (i.e. sizing and co...

Process flowsheet optimization : recent results and future directions

Designing a Process Flowsheet

The appearance and form of piping and instrumentation diagrams (P&IDs) have changed little over time, despite decades of technology improvements. A P&ID created 60 years ago on the drawing board, using ink pens on linen sheets, describes a process the same way as one created today using modern computer-aided design (CAD) software. P&IDs continue to be fundamental references for any process faci...

Flowsheet Optimization of a Lubricant Base Oil Hydrotreatment Process

Unsaturated, nitrogenated and sulfured compounds may reach undesirable levels in lubricant base oils, requiring hydrotreatment (HDT) at high temperatures and pressures. HDT processes are well known for their high capital and operational costs due to the use of hydrogen, compressors and multistage heterogeneous reactors. Process costs are thus highly dependent on the applied conditions. An overs...
