  • Oil Refineries Fail to Report Millions of Pounds of Harmful Emissions

    Executive Summary This report summarizes the findings of an investigation by the minority staff of the House Government Reform Committee into fugitive emissions from oil refineries. The investigation was requested by Rep. Henry A. Waxman, the ranking member of the Committee on Government Reform. It finds that (1) oil refineries vastly underreport leaks from valves to federal and state regulators ...


  • The MACT for petroleum refinery FCCs is a fraud!

    This paper is a continuation of the author's research on the MACT regulation for abating pollution from Petroleum Refinery FCCs in the US. This paper highlights the flaws in the recently promulgated MACT for NSPS and non-NSPS FCC units. It details the inadequacies and the potential for perversity in the New Source Performance Standards (NSPS) that are an integral part of the FCC MACT. It ...

  • CFD Analysis for NOx-Control in a Refinery

    Refineries are required by law to reduce the emission of nitrous oxides (NOX) to the atmosphere. Spray nozzles are key components in the gas conditioning equipment used to control the humidity and temperature of the gases, providing controlled volumes of liquid with predictable drop size and consistent spray coverage. Knowing these values is vital for the optimization of gas conditioning ...

  • Control VOC`s in Refinery Wastewater

    Oil and water do not mix, like many of life’s one-liners this statement is basically true but not the whole story. Many hydrocarbon liquids, particularly aromatics, have significant solubilities in water: Benzene 1800 PPMVToluene 470Ethyl Benzene 150Xylenes 150 Petroleum refineries do not like salts in their feedstock since these corrode and foul process equipment. The first refining step is ...

  • Risk Assessment: Refinery MACT 1 and 2

    Section 112(f)(2) of the Clean Air Act (CAA) requires the U.S. EPA to determine for source categories subject to Maximum Achievable Control Technology (MACT) standards whether the emission standards provide an ample margin of safety to protect public health.  This assessment is carried out by the U.S. EPA in a two-step ...

  • Refinery MACT II Compliance – Are We There Yet?

    Refinery MACT II, 40 CFR Part 63 Subpart UUU, was published in Federal Register on April 12, 2002 by the U.S. Environmental Protection Agency (EPA). This rule, as a subpart of the National Emission Standards for Hazardous Air Pollutants (NESHAP), controls hazardous air pollutants from catalytic cracking units (CCU), catalytic reforming unit (CRU), sulfur recovery units (SRU), and bypass lines ...

  • Oil refinery vapour gas case study

    1.0 Evaluation of Refinery Gases Various refinery gases are generated in the process of oil refining. These vary, depending upon the type of crude oil being distilled, such as Reduced Crude distillation, or Naphtha cracker. For the purposes of this case study the description and range of refinery gases are those gases produced from refining Crude Oil and Reduced Crude only. Crude ...

  • Oil refinery experience with the assessment of refinery effluents and receiving waters using biologically‐based methods

    The trend in discharges of petroleum‐related substances from refineries in Europe shows a consistent picture of declining emissions, since first measured in 1969. This decline coincides with enhanced internal capture or recycling procedures and increasing use of physical and biological treatments. At the same time, and partly in response to legislative drivers, there has been an increase in ...

  • A constant eye on emissions

    Due to increasingly rigorous requirements for regulatory and permit compliance, organisations are seeking more from all compliance support systems. The ability to expand systems to encompass new, or migrate existing, regulatory calculations used to monitor environmental performance is vital. Planning strategically for a scalable and sustainable system has been shown to reduce overall compliance ...

  • An integrated tool to forecast and reduce refinery contribution to SO2 pollution peaks

    For many plants, the annual average impact is significantly lower than the regulation limit. Nevertheless, in some critical meteorological conditions, pollution peaks may occur. The present study describes an original control method for refinery emissions based on meteorological forecast and dispersion modelling, to avoid SO2 pollution peaks. An integrated ...

  • Green supply chain parameters for a Canadian petroleum refinery company

    This research studies environment dimensions of Canadian petroleum refinery companies. It proposes an analysis of the supply chain and focuses on specific actions related to the following: reduction of contaminants; analysis of the operations process; development of parameters and characteristics that can evolve into a benchmarking system for measuring greenness efforts of petroleum refineries. ...

  • Managing continuous emissions monitoring systems

    With recent rulemaking governing compliance determinations in regards to the emissions of nitrogen oxides (NOx) and highly reactive volatile organic compounds (HRVOCs), the Texas Commission on Environmental Quality (TCEQ) required more frequent monitoring which resulted in the installation of more monitoring systems at the facility. This large Gulf Coast refinery decided to utilize the ...

  • Turning Carbon Emissions Into A Revenue Stream

    On the heels of the EPA’s new carbon rules proposed by President Obama on June 2, I wanted to take a closer look at a potential disruptive technological breakthrough: taking CO2 waste streams and turning them into saleable, value-added feedstocks. Certainly, the deployment of renewables, energy efficiency, smart grid, and energy storage technologies offer some of the most cost-effective ...

  • Application of the EU Emissions Trading Directive

    Synthesising Member State reporting on the ETS The European Union (EU) emissions trading system (ETS) is one of the key climate policy instruments implemented in the EU to achieve its emission reductions objectives in a cost‑effective manner. The EU Emissions Trading Directive (EU, 2003, referred to hereafter as the 'EU ETS Directive'), and in particular Article 21 ...

  • IFDM modelling for optimal siting of air quality monitoring stations around five oil refineries

    An IFDM modelling study has been conducted to determine the optimal siting of air quality monitoring stations around five oil refineries. The purpose of this immission monitoring network is specified in environmental legislation. The most appropriate output parameter of the IFDM model for this study is the 98th percentile of the moving 24 h averages, P98,m24h. Modelling for the optimal siting of ...

  • U.S. EPA Proposed Benzene Fenceline Monitoring for Refineries Amongst Other MACT and NSPS Changes

    U.S. EPA has proposed an amendment to 40 CFR Parts 63, Subpart CC and Subpart UUU that requires all petroleum refineries to deploy passive time-integrated benzene samplers at the fenceline (where fenceline is equivalent to the facility property line) of their facility to alert them of fugitive emissions from leaks of Subpart ...
