Análise e simulação de uma planta de produção de cloreto de etila através do simulador de processos comercial Aveva Process Simulation

Abstract

Computer simulation allows estimates of industrial processes to be made without the need to build a real plant. Through it, it is possible to evaluate the best conditions for the realization of the proposed process. In this context, the objective of this work was to simulate a production plant of ethyl chloride and verify the influence of some variables in the process, as well as the estimated revenue loss and gain for each of the proposed changes. For this, the AVEVA Process Simulator was used, software capable of performing simulations efficiently and accurately. A base simulation was used as the simulation described in the book “Computer Methods in Chemical Engineering” (2018). Subsequently, variables of interest such as heat exchanger temperature, recycle ratio and distillation tower pressure and temperature were changed in order to improve ethyl chloride production. For economic analysis, the CAPCOST (TURTON et al., 2018) spreadsheet was used to estimate the cost of the equipment under the given proposed conditions. Through evaluations, it was possible to realize that although the values of the equipment increase in some conditions, this is offset by the increase in product revenue, since its flow rate and output composition are improved.
