Abstract�� During the capability-enlarging modication of the crude benzol rectifiering in Shanxi Coking Co.,Ltd.,ability of 7 kt/a process is enlarged to 20 kt/a.The calculation shows that the original diameter of column can meet require of alteration,and float valve is replaced by vertical sieve-plate.Examination of comparison indicates that vertical sieveplate has characteristic of large capability and small resistance.
