FIELD: chemical industry; methods of neutralization of the water combustible solutions of the acetic acids at the computerized batching-packing machine. ^ SUBSTANCE: the invention is pertaining to the field of chemical industry, in particular, to the method neutralization of the acetic acid and its solutions at leakages and accidents. The method of neutralization of the water combustible solutions of the acetic acids at the computerized batching-packing production line provides for the treatment of the surface, on which there is a leakage of the acetic acid, with the powdery anhydrous sodium carbonate. The treatment of the spilled acetic acid is exercised till formation of the paste and the paste is left on the surface for a while. At the second and the subsequent leakage of the acetic acid on the tray and at formation of the liquid phase the place of the spill is treated with a sodium carbonate till formation of the paste with the purpose for binding the liquid phase. In the case the acetic acid spills on the surfaces located outside of the tray, the neutralization of the acetic acid is exercised by water till gaining the 25-30 % solution. The surface treatment with the powder of the sodium carbonate at the first spill is exercised at the following components ratio (in mass %): Na2CO3:CH3C00H = 1.6/4.0:1. The invention ensures reduction of the wastes of the production process, allows to reduce emission of CO2 and allows to diminish toxicity of the production process. ^ EFFECT: the invention ensures reduction of the wastes of the production process, reduction of emission of CO2 and reduction toxicity of the production process. |
