TL;DR: In this paper, the authors argue that the gap between the science-based and the systems-based research in chemical engineering may be closed by broadening the definition of Process Systems Engineering through the introduction of the concept of the chemical supply chain and gaining a better appreciation of the intellectual research challenges in this area.
Abstract: Introduction Companies must design and operate chemical processes effectively and efficiently so they may survive in today’s highly competitive world. Providing the methods, tools and people that allow industry to meet its needs by tying science to engineering is a compelling aspect of Process Systems Engineering (PSE). Despite the importance of the PSE, the scope and research of this area are often not well understood. One of the major reasons is that chemical engineering has evolved over the past five decades from being an engineering discipline rooted in the concept of unit operations to one based on engineering science and mathematics, and most recently to one with increasing ties to the natural sciences. This very significant change in emphasis has created a gap between the science-based and the systems-based research in chemical engineering. We argue here that this gap might be closed in two ways: first, by broadening the definition of Process Systems Engineering through the introduction of the concept of the “chemical supply chain,” and second, by gaining a better appreciation of the intellectual research challenges in this area. We address this last issue by discussing the nature and major accomplishments of the PSE area and outlining emerging research directions.

TL;DR: In this paper, negative emissions technologies (NETs) that remove and sequester carbon dioxide from the air will need to play a significant role in mitigating climate change, and the benefits, risks, and sustainable scale potential for NETs and sequestration are assessed.
Abstract: To achieve goals for climate and economic growth, “negative emissions technologies” (NETs) that remove and sequester carbon dioxide from the air will need to play a significant role in mitigating climate change. Unlike carbon capture and storage technologies that remove carbon dioxide emissions directly from large point sources such as coal power plants, NETs remove carbon dioxide directly from the atmosphere or enhance natural carbon sinks. Storing the carbon dioxide from NETs has the same impact on the atmosphere and climate as simultaneously preventing an equal amount of carbon dioxide from being emitted. Recent analyses found that deploying NETs may be less expensive and less disruptive than reducing some emissions, such as a substantial portion of agricultural and land-use emissions and some transportation emissions. In 2015, the National Academies published Climate Intervention: Carbon Dioxide Removal and Reliable Sequestration, which described and initially assessed NETs and sequestration technologies. This report acknowledged the relative paucity of research on NETs and recommended development of a research agenda that covers all aspects of NETs from fundamental science to full-scale deployment. To address this need, Negative Emissions Technologies and Reliable Sequestration: A Research Agenda assesses the benefits, risks, and “sustainable scale potential” for NETs and sequestration. This report also defines the essential components of a research and development program, including its estimated costs and potential impact.

TL;DR: In this paper, the authors give an overview of the optimization strategies that are required when designing chemical processes in which the existence of regions of feasible steady-state operation must be ensured in the face of parameter variations.

TL;DR: An overview for deriving MINLP formulations through generalized disjunctive programming (GDP), which is an alternative higher-level representation of MINLP problems, is presented and a review of solution methods for GDP problems is provided.
Abstract: This work presents a review of the main deterministic mixed-integer nonlinear programming (MINLP) solution methods for problems with convex and nonconvex functions. An overview for deriving MINLP formulations through generalized disjunctive programming (GDP), which is an alternative higher-level representation of MINLP problems, is also presented. A review of solution methods for GDP problems is provided. Some relevant applications of MINLP and GDP in process systems engineering are described in this work.

TL;DR: Process Systems Engineering (PSE) is a relatively recent discipline as discussed by the authors which was coined about 50 years ago at the outset of the modern era of computer-aided engineering and has been widely used in chemical engineering.
