As a significant effort to support a new Ethane Cracker, Keystone performed project management, engineering, and design for the $165MM expansion of an underground storage terminal in Sulphur, LA. The project's scope included installing a new brine pond, four ethylene transport pumps, ethylene dehydration system, CO2 Scrubber, flare system, and piping to the new wells at the underground storage facility. Additionally, Keystone executed the design of the associated meter stations and horizontal directional drill packages for the new Ethane & Ethylene pipelines.
