Title: Gianni Torreggiani: Innovator in Ethanolamines and Ethylene Oxide Processing
Introduction
Gianni Torreggiani is a notable inventor based in Busto Arsizio, Varese, Italy. He has made significant contributions to the field of chemical engineering, particularly in the production and purification of ethanolamines and ethylene oxide. With a total of four patents to his name, Torreggiani's work has had a substantial impact on industrial processes.
Latest Patents
One of his latest patents is a process for the preparation and recovery of ethanolamines. This innovative method involves passing ammonia in counter-flow with water and a recycled ammoniacal solution through an absorption column equipped with internally cooled bubbling-trays. The process aims to obtain an ammoniacal solution containing 20 to 50% by weight of ammonia. The ammoniacal solution is then reacted with ethylene oxide in both isothermal and adiabatic reactors to achieve nearly complete conversion to ethanolamines. The process also includes steps for removing unreacted ammonia and recycling part of the water from the reaction product.
Another significant patent by Torreggiani is for the purification of ethylene oxide. This process purifies crude ethylene oxide from a dilute aqueous solution obtained through the extraction of ethylene oxide from a gaseous stream. The purification involves desorption, liquefaction, and distillation in a fractionating column, followed by a final desorption treatment to eliminate absorbed non-condensable gases. The innovative design of the fractionating column utilizes the condensation of water vapor evolved during desorption, enhancing the efficiency of the process.
Career Highlights
Throughout his career, Gianni Torreggiani has worked with prominent companies in the chemical industry, including Società Italiana Resine S.p.A. and Società Italiana Resine S.i.r. S.p.A. His expertise in chemical processes has positioned him as a valuable asset in the field.
