Abstract

The main purpose of this paper is to conduct a comprehensive study that would lead ultimately to an integrated design of a plant that produces formaldehyde with a production capacity specified in advance. This study is take into consideration aspects including the entire plants process unit design, process flow diagrams, cost estimations, operation parameters, equipment sizing, construction materials and safety precautions. The most widely produced grade is formalin(37 wt% and 43 wt% formaldehyde in solution). In this study, formaldehyde is to be produced through a catalytic vapour – phase oxidation reaction involving methanol and oxygen. The projects target design a plant with a capacity of 120 tons formalin/day. It includes a evaporator, a reactor, an absorber, etc .All are to be designed and operated according to this production capacity. Water and sulphur-di-oxide are formed and as by product di- methyl-di-sulphide is formed during complete oxidation of methanol and partial oxidation of methyl mercaptane. The produced formaldehyde will also react further with oxygen to form either complete or partial oxidation products i.e. CO, CO2 and H2O.
