MOSCOW (MRC) -- The US Department of Justice (DOJ) and the US Environmental Protection Agency (EPA) have announced that Shell Oil has agreed to resolve alleged violations of the Clean Air Act at a large refinery and chemical plant in Deer Park, Texas, by spending at least USD115 million (MM) to control harmful air pollution from industrial flares and other processes, and by paying a USD2.6 MM civil penalty, reported Hydrocarbonprocessing.
Shell has agreed to spend USD1 MM on a system to monitor benzene levels at the fence line of the refinery and chemical plant. The fence line is located near a residential neighborhood and school. As part of the agreement, Shell will make the benzene level data available to the public via the web.
Shell will spend USD100 MM on technology to reduce harmful air pollution from industrial flares, which are devices used to burn waste gases. Shell is required to take the following actions to improve flaring operations: minimize flaring by recovering and recycling waste gases (which may then be reused by Shell as a fuel or product); comply with limitations on how much waste gas can be burned in a flare (flare caps); and install and operate instruments and monitoring systems to ensure that gases that are sent to flares are burned with 98% efficiency.
Shell’s agreement to recover and recycle waste gases (flare gas recovery) at its chemical plant is the first of its kind.
Once fully implemented, the pollution controls required by the settlement will reduce harmful air emissions of sulfur dioxide, volatile organic compounds (including benzene) and other hazardous air pollutants, by an estimated 4,550 tpy. These controls will also reduce emissions of greenhouse gases by approximately 260,000 tpy.
Also, in a second project to benefit the community, Shell has agreed to spend USD200,000 on retrofit technology to reduce diesel emissions from government-owned vehicles operating in the vicinity of the Deer Park complex.
We remind that, as MRC wrote previously, Royal Dutch Shell has taken a final investment decision to increase production capacity at its Singapore petrochemical plant to meet demand for specialized materials used in the automotive and furniture industries. The upgrade will increase the plant's capacity to produce polyols - industrial chemicals used to make high-quality foams - by more than 100,000 metric tpy to 360,000 tpy. The project is expected to be completed in 2014.
Shell, which is headquartered in Houston, processes approximately 330,000 bpd of crude oil at its Deer Park facility, making it the 11th largest refinery in the US. In addition, the Deer Park chemical plant produces approximately 8,000 tpd of products including ethylene, benzene, toluene, xylene, phenol and acetone.
