Title: Preparation of hydrofluoric acid
Inventor: MIKI MASAHIRO
IPC: C01B7/19
Filed: 1985-01-11
Abstract: PURPOSE:To reduce total consumption of fuel consumed in the preparation of HF by mixing a washing acid from which major portion of HF contained therein is removed by boiling with H2SO4, fuming sulfuric acid, and fluorite to cause reaction. CONSTITUTION:A part or whole of H2SO4 used for the reaction is fed to an HF gas washing tower, and washing acid contg. 5-15% HF generated from a reactor is heated in a heat exchanger made of commercially available 'Teflon(R)', thus, the content of HF in the washing acid is reduced to 0.1-4%. For the heat source, 1-5kg/cm<2> steam is used, so the heating is regulated to 100-150 deg.C. Thereafter, the washing acid is mixed with residual amt. of H2SO4 and fuming sulfuric acid, and mixed further with fluorite at 90-120 deg.C to cause reaction by absorbing external heat. In this stage, almost no latent heat of vaporization is lost, the reaction is proceeded smoothly, and the reaction product becomes easily flowable powder. By this method, almost no fuel is necessary for the vaporization of HF.
