In this case history, the BP Texas City site (a refinery and chemicals plant) successfully implemented a real-time environmental data management system to comply with the highly reactive volatile organic compound (HRVOC) rule from the Texas Commission on Environmental Quality (TCEQ). This unique rule is part of TCEQ's overall strategy within the Texas State Implementation Plan to bring the Houston area into attainment for ozone under the Clean Air Act. The BP Texas City site is located in the Houston/Galveston area in which this program applies.
The BP facility is widely regarded as the most complex refinery in the world, with a capacity of 460,000 bpd. Additionally, the BP Texas City chemicals plant is the largest producer of paraxylene and metaxylene globally. The challenges faced and benefits attained, when implementing the real-time environmental data management system for HRVOC rule compliance, will be presented. The Air Emissions Management System (AEMS) HRVOC Project was very complex due to the size, intricacy and geographic diversity of the site; coordination required with other internal related projects, such as an HRVOC infrastructure project; and the ongoing re-commissioning of the facility from an extended shutdown after Hurricane Rita. In the future, the system will be expanded to include nitrous oxides (NOx) mass emissions cap and trade program, and flexible air permit requirements.
