The P-graph (process graph) framework is an effective tool for process-network synthesis
(PNS). Here we extended it to multi-period operations. The efficacy of the P-graph …

The primary aim of process-network synthesis, or PNS in short, is to determine the best
process network achieving a desired goal, eg, producing a set of desired products or satisfy …

The process graph (P-graph) framework was introduced in the early 1990s as a graph
theoretic approach to Process Network Synthesis (PNS) problems in chemical engineering …

An extension of the P-graph approach for multi-period process network synthesis (PNS) is
proposed in this work. A modification of a previously published approach enables partial …

The current work demonstrates that separation-network synthesis (SNS) problems can be
transformed into process-network synthesis (PNS) problems: the SNS problems constitute a …

P-graph is a combinatorial optimisation framework aimed at optimising process networks. It
is particularly efficient in handling problems with high combinatorial complexity and it has …

Process network synthesis (PNS) has enormous practical impact; however, its mixed integer
programming model is tedious to solve because it usually involves a large number of binary …
