Abstract
"PROCESSO PARA A FABRICAçãO DE ACRILONITRILA OU METACRILONITRILA", sendo o referido processo para aperfeiçoar a recuperação de cianeto de hidrogênio (HCN) obtido a partir do efluente de reator de uma reação de amoxidação de propileno ou isobutileno, compreendendo a etapa de passar o efluente de reator através de uma coluna de têmpera, uma coluna de absorção, uma primeira coluna de destilação, uma segunda coluna de destilação, um resfriador e um pote de extração ("knock-pot out"), no qual o aperfeiçoamento compreende a etapa de contatar a fase de vapor contendo o cianeto de hidrogênio com uma corrente aquosa.
