Abstract

Предложен способ in situ отбора проб и измерения степени дисперсности частиц (например, технического углерода) в технологическом потоке, например, в реакторе получения технического углерода, включающий в себя а) отбор пробы частиц in situ из технологического потока; б) подготовку пробы к условиям, подходящим для ИЛН; в) измерение степени дисперсности с использованием ИЛН; и г) корреляцию ИЛН-измерений степени дисперсности по действительной степени дисперсности частиц. Предложен также способ in situ отбора проб содержащего частицы потока и измерения степени дисперсности частиц с использованием индуцированного лазером накала (ИЛН), включающий в себя а) отбор пробы частиц in situ; б) подготовку пробы к условиям, подходящим для ИЛН; в) измерение подготовленной пробы с использованием ИЛН; и г) корреляцию ИЛН-измерений по действительной степени дисперсности частиц. Также предложен способ отбора проб и управления процессом на основе оперативных способов in situ отбора проб и измерения частиц в режиме реального времени. Отбор проб может включать в себя извлечение отводного потока из источника частиц. Подготовка пробы к условиям, подходящим для ИЛН, может включать в себя разбавление пробы или доведение температуры пробы до условий окружающей среды. Корреляция может включать в себя использование функции корреляции, определенной путем сравнения ИЛН-измерений и лабораторных измерений степени дисперсности проб частиц, извлеченных в одно и то же время.Международная заявка была опубликована вместе с отчетом о международном поиске.
