CARBON BLACK SAMPLING FOR PARTICLE SURFACE AREA MEASUREMENT USING LASER-INDUCED INCANDESCENCE AND REACTOR PROCESS CONTROL BASED THEREON

摘要

In the present invention, there is provided an in-situ method of measuring the in-situ sampling and fine particles (for example carbon black) fineness in the process stream such as in a carbon black reactor, the method for in-situ sampling (a) particles from the process stream step, (b) adjusting the sample to conditions suitable for LII, (c) measuring the fineness using LII, and (d) includes the step of correlating the measured actual particle fineness help LII fine do. Particle-in-situ sampling containing stream and the laser method of measuring the fineness particles using induced incandescence method (LII) (a) a step of in-situ sampling a particle, (b) adjusting the sample to conditions suitable for LII that step, (c) measuring the adjusted sample using LII, and (d) of the actual particle fineness help LII fineness including the step of correlating the measured value. The invention also includes a sampling and process control methods based on real-time, on-line, in-situ method for sampling and measuring particles. Sampling may include a side stream emanating from a source of particles. Adjusting the sample to conditions suitable for LII can comprise the changing of the temperature of the sample or to dilute the sample to ambient conditions. Correlating may include using a correlation function determined by comparing the laboratory fineness measurements for particle samples leaked LII measurements and at the same time.
