To protect the core downstream reaction of catalysts, you will need the protective purification process solution in the upstream to provide a full scope of safeguards. Otherwise, impurities, poisoning, and more deactivation challenges will take place to cause unplanned reaction or unit failures.

Chempack’s mature purification technologies and the broad portfolio of material process, including the removal of arsine, phosphine, chloride, halogen, sulfur, mercury, O2, CO, H2, and together with the dehydration and special adsorbing process, are going to solve your purification problems. With that, your efficient reactor process management and effective output of pure end products will be fully ensured. Moreover, our reasonable price structure and relatively lower labor costs enable us to provide you the most cost-effective purification solutions.

Arsine & Phosphine
Removal Process

In the hydrocarbon processing, arsine, phosphine, and other arsenic compounds have been the common poisons to the downstream catalysts. Such as in the polypropylene plants and natural gas processing, they can contaminate and poison the catalysts in the down stream of the reactor tower.

For the arsine guard and phosphine guard, following are the key adsorbent products considering different feedstock characteristics for your specific reaction planning, engineering, and improving.
