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.
