Nitrogen Drying

Temperature swing adsorption systems are used to remove all levels of water contained in a nitrogen gas stream.

Olefin Drying

Chemical Design has the capability to design and build highly efficient dryer systems capable of removing moisture from olefins such as ethylene (C2H4) and propylene (C3H6). The system pictured typifies this arrangement.

Phosgene Production

Phosgene is an intermediate chemical used in the manufacture of Isocyanates, Chloroformates, Acid Chlorides, and specialty chemicals. Because Phosgene is toxic, reliable facilities with minimum inventory are required for personal safety. Chemical Design, Inc. has a...

Polycrystalline Silicon Vent Gas Recovery

The manufacture of polycrystalline silicon generates a vent gas comprised primarily of hydrogen, chlorosilanes, and hydrogen chloride.  Chemical Design’s process combines compression, absorption, distillation, ambient adsorption and cryogenic adsorption to purify the...

Proplyene Gas Liquid Drying Purification

The Chemical Design Propylene (C3H6) dryer system utilizes our proven adsorption process to remove water from both gas and liquid propylene down to less than 1 ppmv. In addition, contaminants such as H2S, CO2 and COS can also be removed. The pictures above show...
