Railway & Railcar Loading Scheme



Nameplate Capacity

Keystone performed multi-discipline engineering, project management, and design services to restart an ethylene cracker located in Sulphur, LA. Keystone’s scope involved moving propylene, CC4, and pyrolysis gasoline from the facility. Keystone designed a new railcar loadout system with a control building and truck loadout station to supplement the existing infrastructure.

The design featured two multi-product loadouts, four propylene loadouts, and one driver-interfaced truck loadout station. Keystone designed a new railway pipe rack that connects existing storage and transfer pumps to the new railcar loading stations and extends to the truck loading area. The facility design included a new control building, housing the PLC and HMI control systems, offices, break room, and washroom.

Additionally, the engineering scope included refurbishing/modifying the flare and relief systems, existing utilities, I&E, and interconnecting piping for new and existing equipment. Keystone performed PHA, LOPA, and SIL studies on all systems.
