The Biazzi Process. For many years, the process for preparing nitroglycerine has been carried out in small batch operations, and the procedure has varied only slightly. In recent years, a modem continuous process, developed by Mario Biazzi of Switzerland, has b n gradually replacing the older manufacturing methods. The apparatus (Fig. 12-12) consists of a nitrator, a separator, and three mechanically stirred washers. The entire... 

In 1935 Dr. Mario Biazzi introduced a further method of continuous manufacture based on the use of stirred vessels for the washing stages and characteristic onion-shaped separators with tangential entries to impart a gentle rotary movement to encourage coalescence and separation (19, 20), Most important perhaps was that this particular arrangement was amenable to remote control from a protected position. It was with the introduction of the Biazzi plants that lead was replaced by stainless steel for reactors and subsequent stages.
