VOCS gas condensation capture and recovery

Suitable for the recovery of various volatile VOCs gases; Fast cooling, high efficiency, meeting different condensing temperature requirements, low temperature can reach -75 ° C

Where do harmful gases come from?

It mainly comes from the cleaning, glue leveling, glue removal, etching and development processes of chip or circuit board production.

high exhaust volume and Low emission concentration

The core process of integrated circuit manufacturing produces a large amount of acid-base, arsane, phosphine, organic and other process waste gases. A local scrubber is required for waste gas condensation capture and recovery.

Organic waste gas mainly comes from cleaning, CVD, photolithography, wet etching, degumming and diffusion processes. The types of organic waste gas mainly include isopropyl alcohol, acetone, propylene glycol monomethyl ether acetate, ethyl lactate, butyl acetate, heavy aromatics, etc.

working principle

Introduce the volatile VOCS gas into the equipment cold box (the device is set to a condensation temperature of 3°C-40°C-75°C-115°C). Other temperature zones can be customized to follow the needs for step-by-step condensation and liquefaction. Some continuous production processes have a dual-channel switching process in the low-temperature section (after one side is blocked by ice, it is directly switched to the other channel for heat exchange and condensation in the cold box, and at the same time, the ice blockage is tested for defrost treatment).
