  • Flare minimisation via dynamic simulation

    This paper describes a project of flare minimisation during plant startup by using dynamic simulation. Dynamic simulation was developed for recovery area in an olefin plant and used to examine startup procedures: approaching shutdown; startup with recycle ethane; starting the cracked feed and increasing the feed to normal production rate. The dynamic simulation gives an insight into the process ...

  • Case study - Biomass generation facility replaces flare

    A southeast-based Biomass Generation facility was interested in improving their current process to meet California’s increasingly stringent air emission requirements. At the time, a flare was being used to oxidize the off-gases from various production processes and storage containers. Catalytic Products International developed a solution that utilized the capabilities of the VECTOR ...

  • Development of Low noise landfill gas flare

    Summary: Increasing requirements of the environmental standards and planning permission conditions create more challenges to the equipment providers. Environment Agency guidance demands low emission levels and local planners put low noise levels in their conditions for landfill sites. Achieving both at the same time with conventional equipment was found problematic. Biogas Technology has ...

  • Evaluating gas-flaring-related carbon emission performance in the Nigerian upstream sector: a comparison of duo methods

    This paper uses DEA-based and non-DEA-based environmental performance measurement methods to develop and evaluate gas-flaring-related carbon emission performance indexes for dominant companies in the Nigerian upstream sector. The study relies on empirical data collected from the Nigerian National Petroleum Corporation’s Annual Statistical Bulletins. Indexes developed from the two methods are ...

  • Gas flaring in developing countries – need for kyoto mechanisms or sectoral crediting mechanisms?

    Gas flaring is a phenomenon that is wasteful in terms of valuable resources as well as a contributor to global GHG emissions, and occurs mostly in developing countries. It can only be mitigated through long-term and strategic investments, involving a myriad of stakeholders. A crediting mechanism could be seen as a starting point to create incentives for both private and public parties to build ...

  • Up in Smoke – How the climate and our health suffer from flaring

    It’s like burning banknotes. Latest statistics from the World Bank (WB) indicate that the amount of gas flared each year is enough energy to supply electricity to several small countries or many millions of households. The flaring of 140 billion cubic metres (bcm) a year releases large quantities of greenhouse gases into the atmosphere – and that is not only bad news for the climate, ...

  • Replacing of mechanical compressors by gas ejectors in flare gas recovery systems

    One of the main concerns of humankind in this century is the global warming induced by the increasing concentration of greenhouse gases in the atmosphere. A promising process for controlling the atmospheric CO2 level is prevention of combustion in flares causing high losses of raw material and energy that could generate more desired products. In the present work, a flare gas ...
