Abstract

Procedimiento inhibidor de polimerización. El procedimiento comprende la inyección de un inhibidor de polimerización en la corriente de los gases de emisión de un reactor de deshidrogenación de etilbenceno para obtener estireno. La inyección del inhibidor se realiza antes de la entrada de la corriente gaseosa en el compresor. De esta forma se evita que haya polimerización dentro del compresor. El procedimiento se usa para inhibir la polimerización de monómetros de aromáticos polivinílicos, tales como el estireno contenido en los gases de emisión de una unidad de deshidrogenación.
