KP Chemical to increase PX capacity for production of PTA

Write: Tale [2011-05-20]
KP Chemical is to increase of paraxylene (PX) for the production of purified terephthalic acid (PTA) at its UOP Parex Process unit. For this, KP Chemical Corp has reloaded its Parex Process unit in Ulsan, South Korea with UOP Parex ADS-37 adsorbent. The reload, completed in June 2007, considerably increases the capacity and makes KP Chemical the 15th Parex operator to utilize ADS-37 since its introduction by UOP in 2004.

Global paraxylene demand is growing at 6% pa. Paraxylene (PX) for the production of purified terephthalic acid, and PTA is used to make polyester for fabric and polyethylene terephthlate (PET) chips for carbonated soft drink and water bottles. UOP's Parex ADS-37 adsorbent has been accepted by the petrochemical industry at an unprecedented rate, mainly due to its ability to reduce bottlenecks in existing Parex units resulting in more paraxylene production.

UOP's ADS-37 adsorbent is used in the Parex process to recover high-purity para-xylene from mixed xylenes. The Parex ADS-37 adsorbent now aids in the production of more than 5,500,000 metric tpa of paraxylene, approximately 21% of worldwide capacity.
