Overview
TPC Group is a Houston-based petrochemical company that describes itself as a global leader in producing value-added products derived from petrochemical raw materials such as C4 hydrocarbons, and as a provider of critical infrastructure and logistics services along the U.S. Gulf Coast. The company supplies a diverse range of quality products to chemical and petroleum-based companies worldwide, with an operating history of roughly 80 years. It is the largest independent processor of crude C4 in North America and a leader across all its major product lines. TPC Group's product portfolio includes di-isobutylene, butadiene, butene-1, fuel products, polyisobutylene, and C4 processing services. These specialized chemical products are used in manufacturing synthetic rubber, fuels, lubricant additives, plastics and surfactants — materials essential to transportation, infrastructure and industrial innovation. The company serves the chemical, plastics, refining, synthetic rubber and other major industries. Strategically located operations along the U.S. Gulf Coast give TPC Group what it calls unmatched reliability, flexibility and technical expertise in the petrochemical supply chain. The company emphasizes safety, environmental stewardship, social responsibility and integrity in its operations, and maintains an ethics hotline for anonymous reporting. Its history traces back to 1940, with major facilities in Houston and Port Neches, Texas, that have been central to U.S. petrochemical production for decades.
History
TPC Group's operating history spans more than eight decades, with roots in two major Gulf Coast petrochemical complexes: Houston Operations and Port Neches Operations. According to the company's official timeline, construction on Houston Operations began in 1940 as Sinclair Rubber, while construction on Port Neches Operations began in 1942 as Neches Butane Products Company. Production started at Port Neches in 1944 and at Houston the same year. After World War II, both operations were placed on standby in 1947, then restarted in 1950 for the Korean Conflict. In 1955, FMC and Tenneco bought Houston Operations, while Texas-U.S. Chemical and Goodrich-Gulf bought Port Neches Operations. The Houston site added Houdry 1&2 units in 1957. In 1961, maleic anhydride from butane was installed at Houston. By 1965, Petro-Tex Houston Operations had its first OXO-D run and received a U.S. patent for a process for dehydrogenation of aliphatic hydrocarbons. Houston added BD spheres in 1967, and Port Neches expanded isoprene extraction in 1968. In 1970, Houston added a 45 million pound per year neoprene unit. Houdry 3 started at Houston in 1973. Port Neches implemented OXO-D in 1975, and in 1976 Houston implemented DMF solvent while Port Neches implemented beta-MOP solvent. In 1977, Houston's neoprene and maleic businesses were sold to Denka, and Tenneco bought out FMC's interest in Houston Operations. Houston licensed ISOM from IFP in 1978 and MTBE from Snamprogetti (ENI). In 1980, Texaco acquired full ownership of Port Neches Operations. Houston's DIB unit started in 1981, and Port Neches began MTBE production in 1982. In 1984, Houston Operations was purchased by Texas Olefins and became Texas Petrochemical. In 1986, Houston Operations achieved the world's first isobutylene dehydrogenation commercial run. Houston installed BHY in 1987. In 1990, Port Neches licensed NMP technology from BASF. In 1994, Port Neches Operations was purchased by Huntsman. The timeline continues beyond 1995, reflecting further evolution of the business. Today, TPC Group operates as a private company headquartered in Houston, Texas, and describes itself as North America's largest independent processor of crude C4 hydrocarbons, with strategically located operations along the U.S. Gulf Coast.
