Abstract
L'invention concerne la concentration d'acides minéraux. L'appareillage comprend un four dans lequel sont placés un ou plusieurs longs tubes verticaux en quartz. L'acide à traiter est introduit à la partie supérieure du tube de quartz, lequel est chauffé de l'extérieur et fixé par ses parties supérieure et inférieure au four. L'acide purifie par passage sur des éléments de garnissage est collecté dans un récipient disposé sous le tube. Application : concentration et éventuellement purification de H2 SO4 .
