ABSTRACT: Low efficiency, negative impacts on the environment and non-profitable operations are the main
shortcomings of out-dated industrial processes. Such systems can be reconstructed and improved
in the direction of multi-product operations. The study of this article focuses on the development
of a method for multi-product operations by reconstructing out-dated industrial processes. This
article contains the theory of a developed method that enables the updating of existing process
units and integrated systems on the basis of reconstruction scenarios and pathways. The goals of
the set out method are: 1) to maintain the existing process units and chemical plants to a greater
extent, 2) to enable the potential for finding new process alternatives and technological solutions,
3) to provide a streamlined operation for all subsystems and total systems, 4) to promote environmental
and social responsibilities, and 5) to apply the concept of the presented reconstruction
method to non-profitable industrial processes. In regard to multi-product operations, a conceptual
model is a suitable tool for the reconstruction of industrial processes. It connects several
software tools and so enables quick decision-making between process alternatives. A reconstruction
method provides foresight into the possible improvements to existing industrial processes. In
comparison with the indirect synthesis of DME (simple reconstruction pathway), the lower operating
costs from the direct synthesis of DME (complex reconstruction pathway) were confirmed.
