AMBROSIO, Cristina Weber; SILVA, Luiz Bueno da e MONTENEGRO, Luiz Cláudio Monteiro. Computational model for the performance analysis of a semi-continuous process of Linz-Donawitz gas distribution. Gest. Prod. [online]. 2010, vol.17, n.3, pp. 525-536. ISSN 0104-530X. http://dx.doi.org/10.1590/S0104-530X2010000300007.
The distribution of Linz-Donawitz gas (LDG), co-product of steelmaking process, among thermoelectric plants enables the conversion of the thermal energy recovered into electric energy providing economic and environmental profits. This paper presents a computational model, based on the discrete event simulation in order to investigate current performance of the semi-continuous gas distribution process in a steelmaking plant as well as its future performances due to production expansion. Different scenarios simulation indicated that an increase in the recovered gas demand is a possible and economically feasible alternative. A reduction of 66% in gas loss is expected with the inclusion of a new consumer that can increase gas demand by 30%. This alternative also improves the system flexibility in situations when the main consumer fails or needs a break or a maintenance interval.
