Task 2: CARPT & CT Data

This task involves reviewing CARPT and CT data reported for DOE since 1995, comparing it with available data, and backing up the data from tapes to CD-ROMs. The data includes a gas-liquid column scale-up study, UGS studies, the effect of pressure and distributor on columns, and more. The backup status is over 80% complete, with approximately 50% of the data already summarized in an Excel table.

  1. Task 2: CARPT & CT Data GOALS • a) Review of the data reported for DOE since 1995 • b) Comparison of the reported data with available data • c) Data backup from tapes to CDROM’s • a) CARPT and CT data reported for DOE • Gas-Liquid Column • Scale-up study: data from 4, 6, 8 and 18 inch column • Studied UGS : 2, 4, 8, 12, 14, 30 cm/s • Effect of pressure: 1, 4, and 10 bars for 6.4” column • Distributor effect: PP(various porosities), SP, CS, cone • Liquid : water, drakeoil, 50% isopropanol • Effect of internals in 18”column) • Eddy diffusivities ( 6” 8” and 8” column)

  2. a) CARPT and CT data reported for DOE Gas-Liquid Column, 1996 not included

  3. a) CARPT and CT data reported for DOE GLS Column, 1996 not included • Few CARPT data reported in 1998 from 4” and 6“ column • No CT data has been reported

  4. b) What has not been reported for DOE? Gas-Liquid System • 4” column, 33% isopropanol, UGS from 4 to 8 cm/s, sintered plate • 4” column, water, UGS from 2 to 12 cm/s, PP-0.23% (CT av.) • 8” column, 1% methanol, UGS from 3.8 to 19.7 cm/s (no CT ) • 8” column, water, UGS from 2 to 12 cm/s, PP-0.1% (CT av.) • 12” column , UGS from 4-11 cm/s, sintered plate (no CT ) • unreported CARPT and CT data for UGS of 14 and 30 cm/s and p=1,4,10 bars in 6.4” column (Boon Cheng) • Effect of static height Gas-Liquid-Solid System • 4”column with 33% and 50% of isopropanol for perforated plate (no CT) • 10” column, at 7%, 14% and 20% solid loads (Bente’s run) • no CT data reported so far Novica’s and Ashfaq’s data

  5. b) Data backup Status • so far more than 80% tapes restored from cca 150 • Corresponding to cca 30 GB of data • Approximately 50% of the data is summarized in Excel table with built-in filter to easily locate it • need for an additional manpower for organizing of the remaining data to finish this task by the end of 2001
