Description
Photograph of exterior of a Styrene Finishing Unit, ca.1930. At center, seven large darkly-colored cylinders can be seen rising above a mesh of metallic equipment and machinery. Small platforms are visible at the peak of each cylinder. Furthermore, metallic ramps can be seen connecting the platforms of adjacent cylinders. At the top of each cylinder, a large pipe and a narrow pipe can be seen connecting to a small cylindrical tank at the top of the platform. Along three of the pipes, a series of rods can be seen running parallel to body of the cylinders. Near the base of the cylinders on the left, two large cylindrical tanks are seen connected to two of the larger cylinders. Further right, additional pipes and metallic rods are visible. In the extreme foreground, a few pipes can be seen emerging near planks of wood on a dirt-covered hill. In the extreme background, a similar array of large cylinders can be seen. Description on the back of the photoprint reads: "The Dow Styrene Finishing Unit. These towers in Los Angeles separate the finished styrene from a liquid mixture of styrene, tars, and other hydrocarbons. The styrene is piped to the rubber companies -- most of the remaining hydrocarbons are piped back to earlier stages in the process ultimately to make more styrene."
