Process for preparing hydrogen fluoride in a rotary tube furnace |
摘要 |
The invention relates to a novel process for preparing hydrogen fluoride in a uniformly high conversion at a high space-time yield with minimal energy consumption by reaction of fluorspar with sulfuric acid in a rotary tube furnace, in which the furnace is divided into three equal-sized zones, each of which is heated indirectly by means of from 1 to 12 independent combustion chambers, there being a temperature gradient between the zones such that the first zone has the highest temperature and the third zone has the lowest temperature.
