The Technology Description Of Formaldehyde Production Plant

The main characteristic of Formaldehyde Plant is adopting tail gas circulation method, can maximum limit the use of energy. And the excess steam can use in urea/melamine formaldehyde plant.
The Formaldehyde Production Plant includes only 3 parts: Evaporator-Reactor-Absorber. Others are either combined into the three or removed.
Detailed technology description.
1) Off-Gas Circulation Process by our formaldehyde machine
Off-gas is used to take away the reaction heat instead of steam. Therefore, formaldehyde concentration is improved and steam is saved.
2) Flue Gas Circulation Process by our Formaldehyde Equipment:
Flue gas resulted from off-gas incineration is employed to raise the yield as well as the run-up safety.
3) Incomplete Conversion Process
An excess of methanol is fed to reduce the reaction temperature and therefore our formaldehyde production line will lower the occurrence of side reactions as well as methanol consumption.

Introduction of Auto-oxidation Process

  Today we will explain  the  Introduction of Auto-oxidation Process . Rancidity may be said to be the subjective organoleptic appraisal of the off-flavour quality of meals. Oxidative rancidity is worried about the changes that lead to the reactions involving the lipids in meals with atmospheric oxygen.Oxidation of unsaturated lipids not only generates offensive odors and tastes but may also decrease the nutrient quality and safety due into the formation of secondary reaction products in foods after cooking the oxidative deterioration of food lipids involves, primarly, the autoxidation response, so called due to its autocatalytic mechanism. the autoxidation is a complex procedure which proceeds through complimentary ra-,dicals by a chain mechanism2- 4 • The Understanding of the autoxidation process, even though not clear in most. The facets, is mainly as a result of study of systems.
