New York City-based SK Capital Partners and global investment firm First Reserve Corp. have acquired TPC Group Inc., Houston — a producer of value-added products derived from niche petrochemical raw materials, and a provider of critical infrastructure and logistics services to the Gulf Coast region.

TPC sells its products to performance, specialty and intermediate markets such as synthetic rubber, fuels, lubricant additives, plastics and surfactants. The company is the largest U.S. producer of finished butadiene, which is used in Wichita, Kan.-based Invista's nylon 6,6 production process.

TPC has manufacturing sites in Texas in Houston, Port Neches and Baytown; and in Lake Charles, La.
