In this process, reactants i.e., methanol is fed to the vaporizer where it exchanges heat with water, Heated methanol is then fed to the reactor where it reacts with Oxygen (Air) with steam injected to avoid deactivation of silver catalyst to form major product (Formaldehyde) along with some tail gases. Product is then fed to the absorption tower where water is used as a carrier solvent for methanol and tail gases are removed from the top of the absorption column. Formaldehyde along with water methanol mixture is fed to distillation column for the removal of major product on the basis boiling point difference. Recycled methanol is taken from the top of the column and heated product formaldehyde (formalin) is taken from the bottom of the column. This product is then sent to the final equipment of the process which is heat exchanger to cool down the main product. The conversion achieved is 92% of the overall product.enDr. Noaman Ul HaqFa19Department of Chemical EngineeringChemical EngineeringOxygenThesis
