METHOD OF REDUCING SCALING OF HEAT TRANSFER SURFACES IN AN EVAPORATION PLANT OF A SULPHATE CELLULOSE MILL |
摘要 |
Method of reducing scaling of heat transfer surfaces in an evaporation plant of a sulphate cellulose mill when sulphate cellulose is manufactured. In the method, ash to be fed into black liquor is mixed thereto after soap separation when the dry solids content of the black liquor is so low that sodium sulphate and other soluble salts contained in the ash dissolve in the black liquor completely.
