In an attempt to construct a new agenda for waste management, this paper explores the complex relationship between definitions of waste and their subsequent impact on its ownership and management. A range of internationally accepted definitions for w

An approach to safety conscious chemical process design is described and illustrated. It is taken for granted that the way the process is represented has a profound influence upon the way process design is done. Thus safety conscious process design c

The paper gives further computational evidence for the argument presented earlier that the high flux correction can be ignored when simulating multicomponent reactive and ordinary distillation even when there are heat effects present, which make the

A solid foundation for a formal theory of waste management is offered in terms of consistent building blocks: language, conceptual schemes, models, and sentence systems. The language used to formulate the theory is the PSSP language, which is a forma

The paper introduces a novel approach to taking a holistic view of industrial products and building formal product models capable of integrating data in a wider perspective than what is implemented in the ISO-10303 and ISO-14040,…, 14043 product mo

Heat effects in distillation, especially those caused by unequal heats of vaporization of components and highly nonadiabatic operation, were shown in earlier papers to cancel favorably in binary distillation when measuring and computing composition p

A rigorous method for solving the modified MESH equations for reactive distillation is elaborated. The equations were formulated as a problem-dependent homotopy in such a way that the homotopy path to a solution is continuous in the prescribed domain

Molecular simulation is of growing importance in chemical engineering. The gap usually present in knowledge representations between disciplines is, however, a serious obstacle for efficient utilization of knowledge. The way of bridging the gap betwee
