Complete Formaldehyde Plant

Formaldehyde, with the chemical formula HCHO and a molecular weight of 30.03, is also known as methanal. It is a colorless gas with a special pungent odor that irritates the eyes, nose, etc. The relative density of the gas is 1.067 (air = 1), and the liquid density is 0.815 g/cm3 (-20°C). Its melting point is -92°C, and its boiling point is -19.5°C. It is easily soluble in water and ethanol. The maximum concentration of the aqueous solution can reach 55%, usually 37%, which is called formaldehyde aqueous solution, commonly known as formalin, a colorless liquid with a pungent odor. It is widely used in industries such as chemical engineering, medicine, textiles, and wood processing. Its largest application is in the manufacture of adhesives for wood processing and furniture production.

Wuxi Suyang Chemical Equipment Co., Ltd. has gathered a group of well-known domestic experts in the formaldehyde field and has cooperated with domestic universities and research institutes to develop an internationally leading silver-process formaldehyde plant. This formaldehyde plant features high conversion rate, low methanol consumption, and large amount of by-product steam. In particular, the new formaldehyde oxidizer has the advantages of long service life, low formaldehyde acidity, and more by-product steam.

Our company can provide customers with one-stop services such as design, manufacturing, installation, and commissioning of complete formaldehyde plants. The plant capacity ranges from 10,000 to 120,000 tons per year, and the formaldehyde product concentration ranges from 37% to 55%. In response to the actual needs of different domestic and international customers, the types of formaldehyde plants we offer are as follows:

1) Traditional bubbling evaporator, with three ordinary concentration-gradient absorption towers, mainly producing 37% formaldehyde aqueous solution;

2) New process evaporation tower type, with three ordinary concentration-gradient absorption towers, capable of producing 37% formaldehyde aqueous solution;

3) Tail gas circulation method, reboiler type, with three ordinary concentration-gradient absorption towers, capable of producing 37% to 42% formaldehyde aqueous solution;

4) Tail gas circulation method, reboiler type, with six concentration-gradient absorption towers, capable of producing 37% to 55% formaldehyde aqueous solution;

5) Tail gas circulation method, evaporation tower type, with six concentration-gradient absorption towers, capable of producing 37% to 55% formaldehyde aqueous solution;

6) Tail gas circulation method, composite evaporator type, with six concentration-gradient rectification and absorption processes, capable of producing 37% to 55% formaldehyde aqueous solution;
