Low efficiency, negative impacts on the environment and non-profitable operations are the mainshortcomings of out-dated industrial processes. Such systems can be reconstructed and improvedin the direction of multi-product operations. The study of this article focuses on the developmentof a method for multi-product operations by reconstructing out-dated industrial processes. Thisarticle contains the theory of a developed method that enables the updating of existing processunits and integrated systems on the basis of reconstruction scenarios and pathways. The goals ofthe set out method are: 1 to maintain the existing process units and chemical plants to a greaterextent, 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 environmentaland social responsibilities, and 5 to apply the concept of the presented reconstructionmethod to non-profitable industrial processes. In regard to multi-product operations, a conceptualmodel is a suitable tool for the reconstruction of industrial processes. It connects severalsoftware tools and so enables quick decision-making between process alternatives. A reconstructionmethod provides foresight into the possible improvements to existing industrial processes. Incomparison with the indirect synthesis of DME simple reconstruction pathway, the lower operatingcosts from the direct synthesis of DME complex reconstruction pathway were confirmed.
