The facility will use the most recent technologies to provide the greatest energy efficiency and lowest emissions. Several environmental measures to be employed include:
- Recycling “tail gas,” a byproduct of the ethane cracking process that is primarily clean-burning hydrogen, to power the ethane cracker furnaces;
- Building a first-of-its-kind ethylene storage unit to handle operational problems rather than having to flare ethylene while fixes are made;
- Using natural gas-fired cogeneration to provide steam and electricity for the facility
Once completed, the facility will recycle and reuse water in its processes, drawing approximately 20 million gallons per day from the Ohio River. Approximately 80 percent will evaporate as clean steam; the rest will be treated to remove impurities and then tested to ensure it meets water quality standards before the water is returned to the river.
Shoreline improvements and erosion protection along the Ohio River adjacent to the facility are already underway. Other steps Shell will take to protect water quality include:
- Recycling condensate (condensed steam from process equipment);
- Groundwater monitoring wells and regular water-quality testing;
- Plans to create, recreate, enhance and preserve in-kind habitats in the same watershed to offset impacts to wetlands and streams on the site.
Shell believes in caring not only for the people of the Monaca Community, but also in caring for the region and the environment. At the core of this is a dedication to maintaining strict environmental standards to keep the air and water clean.
The site of our new facility, formerly a zinc factory, has been reclaimed to environmental standards established by the State. We have taken the following steps to lower our environmental impact and to minimize the effects of our presence on the local aesthetic.
- Appropriately contained decades of environmental impacts from former industrial uses and made sure surface waters are protected
- Obtained the lowest feasible air emission due to design, regulatory limitations, control technologies and work practices
Shell is also investing to create a wetland at the Tank Farm located in Potter Township. This project will help water run-off issues into Raccoon Creek and serve as a learning area for residents and the community around matters of habitat and wildlife.
