Project Scope

Graycor Industrial completed construction of a new hydrogen plant for Praxair at its Whiting, Indiana, facility. The multimillion-dollar project enables Praxair to supply hydrogen to BP’s Whiting refinery. BP, one of the world’s largest oil and gas firms, uses the hydrogen in production of ultra-low-sulfur gasoline and diesel fuels. The new plant serves to refine the oil sands being shipped from Canada to BP’s Whiting refinery. In addition, the plant also supplies hydrogen to other customers in northern Indiana.

Praxair is the largest industrial gases company in North and South America and one of the largest worldwide. Work at the brownfield project site, where coke battery foundations once existed, called for Graycor Industrial’s team to construct two steam methane reformers (SMRs), as well as an office/maintenance building, a water purification building, pressure swing adsorption structures and multiple pre-engineered metal buildings. The project scope also included site work, underground utilities, foundations, rotating equipment, structural steel, complete piping and electrical/control systems.
