Análisis Tecno-Económico de Gasificación de Polietileno, caso en México

Abstract

As a way to encourage the use of new technologies for the recycling of plastic, the research will obtain techno-economic data for the possible chemical recycling of plastics, the gasification of polyethylene. It was simulated in ASPEN PLUS parcel to technically and economically analyze the viability of the gasification process, taking into account the restrictions and considerations of said process. The main plastic waste that is disposed of in landfills are polyethylene terephthalate, polystyrene and low and high density polyethylene. Gasification is a thermochemical process in which a carbonaceous substrate (in this case plastic) is transformed into a combustible gas through a series of reactions that occur in the presence of a gasifying agent (usually air) in an oxygen-poor environment. The work demonstrates the viability of this type of processes used in plastics such as high and low density polyethylene.
