Abstract: A system and method for continuous batch monitoring of key quality characteristics of the production of precisely targeted FAC, optimally HOCl, through use of pressure, temperature, pH, ORP, tonicity sensors and spectroscopy instruments measuring the dynamic averages of product in a circulating vessel that informs the input production system through a dynamic feedback loop to make corrective formulations of key characteristics such that corrections occur to the constantly monitored HOCl solution in order to meet verified quality standard at the storage vessel's point of dispensing.

Abstract: The present invention relates to fractionation improvements. Thus, in a fractionator having a fractionation vessel, a reactor effluent vapors inlet, a vapor feed contacting zone, a baffled contacting section above the vapor feed contacting zone, a tops section above the baffled contacting section, a heavy bottoms liquid hold-up pool section below the vapor feed contacting zone, a bottoms outlet, a bottoms recycle system with a heat exchanger with recycled, cooled bottoms fed back to the fractionation vessel at the heavy bottoms liquid hold-up pool section and above the vapor feed contacting zone, the improvements involve a separate remotely located bottoms liquid hold-up pool vessel for separating bottoms liquid holdup from vapor within the fractionation vessel to obtain a thermal separation and increased fractionation efficiency. The invention also relates to fractionation processes utilizing the aforesaid improvements.
