South Jersey Gas Reduction of climate change-driven risks and greenhouse gas emissions through prudent, deliberate strategies to prevent pollution, minimize waste and mitigate adverse environmental impacts.
In 2021 SJI performed a pilot study and utilized ZEVAC technology for depressurization of the pipelines to further minimize environmental and social impact during a blowdown event. Instead of releasing the gas into the atmosphere, ZEVAC equipment moves the gas out of the pipeline being depressurized into another section of the system.
