CC4 Processing

Crude C4 (CC4) Overview

TPC Group secures its crude C4 (CC4) feedstock from ethylene crackers around the world. We operate two world-scale C4 processing plants where we aggregate our supplies of CC4 feeds. TPC plays an essential role and has earned the trust of olefin producers through our extensive capabilities and commitment to upgrading the value of their mixed C4 olefin production (CC4) into finished products for sale to our customers using key products such as butadiene and butene-1. We have multiple units with reliable, environmentally-sound operations to process crude C4 at both our Houston and Port Neches, Texas facilities.

At TPC Group, we have an extensive logistics network that ensures efficient receipt of raw materials and delivery of our products regardless of shipment mode. Crude C4 raw materials and products are delivered by pipeline, ship, barge and rail. TPC Group has substantial storage facilities, more than 200 miles of pipeline, and world-class dock and rail facilities. TPC has a unique supply chain infrastructure at both our Houston and Port Neches facilities. We have access to multiple ship docks that can accommodate both barges and ocean-going vessels.
