Coke at a temperature of 700-1000 deg.C is quenched by means of an aqueous solution of iron (II) and iron (III) salts with a pH-value above 7.5. This solution contains 20-2500 mg/dm<3> iron (II) ions and 5-625 mg/dm iron (III) ions, as well as 1-50 mg/dm<3> monoester disodium salt of succinic acid with oxyethylenenonyl phenol. The cooling solution is made up of 40-80% coke quenching circulation water, 10-30% biologically cleaned process water from coke production, and 10-35% return water from the cooling circuit refreshment system. The foamed suspension of water and air mixture from the coke is subjected to flow-through condensation and expansion. |
