Prior to the formation of PetroLogistics II LLC, David was the Executive Chairman of PetroLogistics LP, an NYSE listed company which developed, owned and operated the first Propane Dehydrogenation facility in North America. At the time of its commissioning in 2010, that facility was the largest PDH plant in the world. Since the sale of PetroLogistics LP to Flint Hills Resources in 2014, David has been working with the PetroLogistics team on developing additional petrochemical projects. The fruition of that effort is the current PDH project using the Dow FCDh technology. David was also Chairman and co-founder of PL Midstream, a privately held petrochemical transportation and storage business with operations in Louisiana. PL Midstream owned and operated salt dome storage facilities in the Baton Rouge and Lake Charles areas which served as important storage hubs for the Louisiana petrochemical industry. The company also owned and operated ethylene and propylene pipeline transportation systems which connected to most major Louisiana producers and consumers of ethylene and propylene. PL Midstream was sold to Boardwalk Partners in late 2012. Prior to establishing these companies, Mr. Lumpkins worked in the investment banking industry for 17 years principally for Morgan Stanley, for which he established the Houston office in 1995. David is a graduate of The University of Texas at Austin, where he received his BBA and MBA degrees.
