Shell officially starts construction on Pennsylvania petchem complex




Shell Chemical Appalachia LLC (Shell), a subsidiary of Royal Dutch Shell plc has officially started the main construction phase of its major petrochemicals complex in Pennsylvania, US. This follows the successful completion of the site preparation and detailed design and engineering work.
The early works programme has been a significant project. Work included building bridges, relocating a state highway, improving existing interchanges, repositioning a rail line, and preparing foundations for the new complex. The site is now ready for the main construction to start.
Shell will now progress to the construction of four processing units – an ethane cracker and three polyethylene units. The ethane cracker will be the largest part of the facility with more than 200 major components and 95 miles of pipe.
Shell will also construct a 900-foot (274-metre) long cooling tower, rail and truck loading facilities, a water treatment plant, an office building and a laboratory.
The site will include a 250-megawatt natural gas-fired power plant, which will produce electricity and steam for the facility. About a third of the electricity produced will help supply the local electricity grid.
The petrochemicals complex will use ethane from shale-gas producers in the Marcellus and Utica basins to produce 1.6 million tonnes of polyethylene per year. Polyethylene is used to make many products, from food packaging and sports equipment to furniture.
