G.L. Sullivan incorporated Conchemco in September of 1990. Conchemco LTD  initially concentrated solely on product dislocations and spot  opportunities. The company was determined to establish a base core of  products that could be sold on an on-going, contractual basis. The program  has been very succesful and Conchemco has been voted 4 times into the Dallas  100 by Dallas Business Journal and the SMU Cox School of Business. The  Dallas 100 represents the top 100 fastest growing privately held businesses  in the Dallas area.  The core products are Acetone and the major aromatic and aliphatic  hydrocarbons. To service these businesses, a large fleet of tank cars has  been added and numerous large shore tanks have been leased into which these  products are received by barge or vessel and redistributed via truck and  rail.  In addition to the core products, the company represents a number of  petrochemical producers and sells many other solvents such as the more  common Alcohols, Ketones, Esters, Glycols, Glycol Ethers, and Glycol Esters,  as well as many of the Amines, Styrene Monomer, Caustic Soda, and specialty  chemicals.  As a member of the National Association of Chemical Distributors (NACD),  Conchemco has a quality program that conforms to the Responsible  Distribution Process (RDP) as prescribed by the NACD.
