Formaldehyde OverviewFormaldehyde OverviewOverview Summary:
In this plant, formaldehyde is produced by the oxidation of Methanol. Utilizing a catalyst Fe-MO supported by ceramic.
The oxygen is fed by using a blower (VV 701) taking part fresh air and part exhaust gases from the outlet of the absorbtion column (C 701) in order to reach the oxygen concentration of the methanol LEL. The concentration is detected continuously by an oxygen analyzer on line.
The gas is fed in the methanol evaporator (E 701) where liquid methanol is added through spray nozzles and evaporated using the heat of the solution taken from a section of the column.
The reaction mixture is fed in (F 701) where it is heated up by gases from the reactors, then goes in the reactors from bottom to top.
The reaction is exothermic and the heat is removed using diathermic oil circulated in each of the seven reactors.
Formaldehyde OverviewFormaldehyde OverviewOverview Summary continued :The gas from the reactors is composed of formaldehyde, oxygen, nitrogen and methanol and goes to the absorption column from bottom to top.
The column is divided in three main sections where the solution is circulated by pumps and the third section is cooled with a plate heat exchanger (F 703).
From the bottom of the column, the formaldehyde solution 36-37 % is sent to the storage tank.
The heat of the diathermic oil is removed in a boiler (H 701) which produces steam at 17 bar-g.
The water to produce steam is fed by a pump.
To start the plant before feeding the gas to the reactors, the reactors have to be heated to the temperature of reaction. This is accomplished by circulating the oil in a burner (B 701) working with natural gas.
