SUMMARY:

In the production of Vinyl Monochloride (MVC) the 1,2-Dichloroethane (1,2-DCE) must undergo a purification process, as the 1,2-DCE cracking process is highly susceptible to inhibition and deposition by traces of impurities. It must have a purity greater than 99.5 %wt/wt. One of the impurities with the greatest inhibiting capacity in the cracking reaction is the presence of Carbon Tetrachloride (CCl₄). Therefore, having an online CCl₄ measurement at the output of the 1,2-DCE purification process allows for greater control of the cracking reaction, avoids production losses, allows for an optimization of the process, in addition to generating a reduction in the campaign time of the cracking ovens. The importance of this real-time analysis, the need to control this impurity and the difficulties in maintaining the analytical instruments motivated the work of developing a model for inferring the analysis. The partial results obtained indicate paths of input variables for inference of the composition of CCl₄, in addition to a viable virtual analyzer model so that these results can be included in the process control.
