Abstract

Un proceso de reclamación MEG incluye el paso de incrementar arriba de 2,000 ppm la concentración de sales de metal divalente de una corriente de alimentación rica de MEG (húmeda) que fluye en un de precipitación. El paso de incremento incluye el encaminamiento de la superficie de flujo MEG de sales saturadas del separador de rebaba al de precipitación. La superficie de flujo puede mezclarse con corriente de alimentación de agua dulce, una porción de corriente de alimentación MEG rica o alguna combinación de las dos. La corriente de alimentación MEG rica también puede dividirse en dos corrientes, con una porción de la corriente que se está calentando o encaminando al separador de rebaba y la otra porción que se está combinando como anteriormente con la superficie de flujo removida. El proceso puede llevarse a cabo en la superficie de flujo después de la dilución y previo a introducir el de precipitación o después de haberse cargado en el de precipitación. La remoción de las sales insolubles pueden realizarse en ya sea un lote o modo continuo.
