FOR IMMEDIATE RELEASE

TPC GROUP COMMENCES DETAILED ENGINEERING FOR RESTART

OF DEHYDROGENATION ASSETS

Exploring Production of Isobutylene Feedstock for Growing

Fuels and Performance Products Businesses

HOUSTON (Friday, February 4, 2011) — TPC Group Inc. (Nasdaq: TPCG) today announced that it has commenced the next steps toward the restart of certain of its dehydrogenation assets at the Company’s Houston Operations with the approval by the Board of Directors of a detailed engineering study. These dehydrogenation assets would serve to provide isobutylene feedstock for the Company’s rapidly growing fuels products and performance products, including polyisobutylenes, high purity isobutylene and diisobutylene.

Total cost for this phase of engineering will be approximately $5 million and will be completed this summer. While commencement of construction would also be contingent on obtaining the necessary operating permits, the Company has previously applied for such permits with the appropriate regulatory agencies.

“TPC Group has a long history of producing isobutylene using our dehydrogenation assets. With butane feedstock availability increasing and the resulting product markets in a structurally short position, we believe that a unique opportunity exists to generate value for our stockholders by returning these assets to service,” said Micheal Bloesch, Vice President of Strategic Initiatives. “Having dehydrogenation capacity coupled to our isobutylene based Performance Products units all at one site gives us advantages that are difficult to replicate.”

The Company owns two independent, world-scale dehydrogenation units whose technology allows the production of a single, targeted olefin from a natural gas liquids feedstock, as opposed to steam cracking technology which must generate a range of various olefins. These existing assets, if refurbished, could be capable of producing on-purpose propylene, isobutylene, butene-1, butadiene, or isoprene from natural gas liquids. The current study contemplates the restart of one of these two idled dehydrogenation units, and the Company is exploring opportunities surrounding the second unit.
