METC/Shell Cooperative Agreement CRADA 93-011 high temperature high pressure filtration and sorbent test program. Volume 2, Final report

This report is a summary of the results of activities of the particulate monitoring group in support of the METC/Shell CRADA 93-011. Online particulate monitoring began in August 1993 and ended in October 1994. The particulate monitoring group participated in six MGCR runs (No. 5 through No. 10). The instrument used in measuring the particle loadings (particle counts and size distribution) is the Particle Measuring Systems Classical Scattering Aerosol Spectrometer Probe High Temperature and High Pressure (PMS Model CSASP-100-HTHP). This PMS unit is rated to operate at temperatures up to 540{degree}C and gage pressures up to 2.07 MPa. Gas stream conditions, temperature at 540{degree}C, gage pressure at 2.93 MPa, and gas flowrate at 0.0157 SCM per second, precluded the direct measurement of particulate loadings in the gas stream with the PMS unit. A side stream was extracted from the gas stream after it came over to the MGCR, (Modular Gas Cleanup Rig), from the FBG, pressurized fluidized-bed gasifier, but before it entered the filter testing vessel. A sampling probe of 0.635 cm O.D. thin wall stainless steel tubing was used for extracting the sample gas isokinetically based on the expected flowrate. The sample gas stream was further split into two streams; one was directed to the PMS unit and the other to the alkali monitor unit
