ABSTRACT:
A method and apparatus for measuring the acid gravity in an inorganic acid-organic fluid system permits constant monitoring of the acid gravity thus allowing the acid strength to be maintained at an optimum level. Particularly in a system such as an alkylation reactor, where product quality is dependent upon acid strength, the acid gravity measuring method and apparatus assures high product quality. A collecting vessel receives the inorganic acid-organic fluid mixture and the acid gravitates from the organic fluid in a disengaging chamber. The acid then enters an acid-analyzing section which includes acid gravity measuring means for determining the specific gravity of the separated acid. By continuously draining the fluid from the disengaging chamber and the acid-analyzing section, fresh fluid can be continuously introduced and the acid gravity continuously analyzed. In the case of an alkylation reactor, the acid gravity measuring means is coupled with valve means disposed in the acid supply line to the reactor. The quantity of make-up acid introduced into the reactor can thus be automatically increased or decreased in response to the measured specific gravity of the acid received in the collecting vessel, and the acid level in the reactor maintained in an optimum level at all times.
