It almost sounds too good to be true.
Take an oil refinery waste product, turn it into a cleaner-burning fuel for chemical plants, and capture and sell all the greenhouse gases.
That’s just what Houston-based Hunton Energy plans to do on a 250-acre site next to Dow Chemical’s Freeport complex.
In a 15-year deal with the chemical giant, Hunton will convert a refining byproduct called petroleum coke into a synthetic natural gas that Dow will purchase and use to run a number of processes on its 5,000-acre site in Freeport. The facility will also produce steam for Dow and generate about 400 megawatts of electricity.
Hunton’s president, Rocky Sembritzky, said the plant will be able to capture essentially all the carbon dioxide it produces — about 8 million tons a year — and will sell it to a third party to use in enhanced oil recovery. The company is in negotiations with three companies for the CO2, he said.
“What we’re planning is a plant that can produce a lot of energy, yet have no emissions except for startup and shutdown,” Sembritzky said. “There’s been a lot of talk in the industry about carbon capture, but we’ve committed to it from day one.”
The Hunton project will help Dow reach its goal of a 20 percent reduction in greenhouse gases by 2015, said Kenneth Bromfield, director of Dow’s energy business.
“The synthetic natural gas component of the project is also significant for us,” Bromfield said, noting that chemical plants use large quantities of natural gas, an increasingly expensive fuel, subject to volatile price swings.
Environmental groups said they are encouraged by the pro- ject, scheduled to break ground late next year and begin operating between 2012 and 2014.
Jim Marston, a Texas-based director of Environmental Defense, praised the project and the participation of Dow and Energy, the refining giant that will provide the new plant’s petroleum coke.
