The Hoechst Celanese Chemical Group (HCCG), Inc. - Pampa, Texas facility converts a component of Texas produced natural gas (Butane) into a variety of industrial chemicals. The Pampa plant's chemicals are the building blocks for a wide variety of consumer products. HCCG Pampa produced chemicals are a part of such familiar items such as carpeting, fabric, automobiles, soda cans, home paints and perfumes. The chemicals produced in Pampa are in the liquid form. They are shipped via rail car to a wide variety of manufacturing companies across the United States, Canada and Mexico. Pampa has completed a progressive project which will virtually eliminate the release of organic vapors during the rail car loading process. The project is best explained by comparison to the every day activity of filling your car's gas tank. When you fill your empty tank with liquid gasoline, vapors in the tank are displaced and are released to the air through the filling nozzle. It's the same as rail cars are filled, vapors in the tank are released. Pampa facility has recently completed the design and installation of a progressive system which virtually eliminates the release of vapors while loading tank cars and tank trucks at the Pampa Plant, the closed dome loading project. The vapors are sent to a flare for distruction.

P2 Application:

The closed dome loading system is state-of-the-art. It is especially innovative in that it was added to an existing loading facility in an older plant.

Environmental Benefits:

The Closed Dome Loading Project will reduce air emissions by an estimated 58.4 tons/year of hydrocarbon vapors, that were an odor control problem.
