Determining the characteristics of the direct coke oven gas tar fog
In the cooling of coke oven gas, the principal part of the tar in the gas main condenses and is discharged to the mechanical clarifiers with the water. The remaining part of the tar is present chiefly in the form of fog. The vapor phase of the tar is insignificant and consists primarily of fractions boiling below 300/sup 0/C. Separation of the tar from the direct gas in the primary gas coolers is determined principally by the conditions of precipitation of the aerosols and absorption of the low-boiling fractions of tar, naphthalene and crude benzol on the drops of tar fog. The particle size of the aerosols in the direct gas is described by a log normal distribution curve. The diameter of the principal part of the particles is 0.8 to 7.0 microns. In the direct gas after the primary gas coolers with vertical tubes at temperatures below 40/sup 0/C there are three condensed phases: naphthalene crystals, water droplets and tar. (JMT)
