Iran formalin|Urea formaldehyde resin powder concentrate

What is Iran formalin?

Iran formalin is 37% to 50% solution of formaldehyde gas in water. Iran formalin is colorless, transparent, highly odorous liquid, an aqueous solution of formaldehyde gas polar solvents. Irritant, toxic and used as the most usable material in chemical, painting and plastic industries and it is the third level of usable chemical materials.

The initial material of formalin is methanol which is an alcohol with boiling point of 65 C which will be evaporated quickly and will produce an explosive gas after being combined with oxygen. We should use sparkle equipment, firefighting equipment, gas leaking sensors, different storage equipped with chiller, Nitrogen gas injection part and etc. in order to prevent risks in transportation and storage of Methanol.

In Iran formalin production unit, first we change methanol to extremely hot vapor by heating and then combine with oxygen and conveyed on catalyst at 300 temperatures. After transmission of combined gases on catalyst in reactor unit, formaldehyde gas will produce.

Formaldehyde process

Iran formaldehyde gas with nitrogen, carbon dioxide and water vapor exit from reactor and conducted to absorption tower after being cold. As a result of water flow, available formaldehyde in gas was absorbed and Formalin solution will be produced and will kept in lower port of tower and conveyed to storage condenser after being cold.

Since chemical reaction of formaldehyde is very complex and dangerous, so advanced computerized unit by use of PLC system, control this process automatically.

After primary quality controls, The produced formalin is transferred to the original storage reservoir which will be sent out for sale or consumptions.
