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 recovery unit (FGRU) ...

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 ...

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 ...

Small scale biogas upgrading: Green gas with the DMT Carborex® MS system
Abstract More and more effort is being put in the utilization of bio-solids. Bio-solids can be an important source for useful products like fertilizers and biogas. DMT has been developing biogas treatment plants for over 20 years following the market developments closely. Biogas was first seen as a nuisance at e.g. landfills, creating odor problems and methane emissions. A flare has always ...

Estimates of CO2 emissions reduction and potential power generation from biogas at Mare Chicose landfill
In this study, the annual generation of Landfill Gas (LFG) and methane using the Scholl-Canyon model have been predicted for 1998-2030 for five scenarios of landfill management at the Mare Chicose landfill in Mauritius. Using the Approved Large-Scale Methodology AM003 and Approved Baseline Methodology AM0010 of the Approved Methodologies for CDM activities, the carbon dioxide (CO2) emissions ...

Multipoint systems measure flare gases – Case Study
To mitigate greenhouse gas emissions, many companies reuse their biogas for cogeneration, but the amount of biogas produced often exceeds the amount needed for cogeneration. In such cases, it is often not economical to purify, compress and store the gas for later use, so it is flared off. Accurate mass flow instrumentation is essential for these companies to comply with the new EPA ...

Performance of the low-emission flare
Job report / Elbisgraben (Bale / Switzerland) The summer of 1992 had finally arrived. The 5MW low emission furnace in the district heating station Liestal was ignited, supplied with landfill gas from Elbisgraben landfill. Since then the plant has been running continuously and the comprehensive measurements taken, verify that all targets aimed at have been achieved: plant efficiency 90%, low ...

EPA Eyes Flare Operations
Control of Volatile Organic Compounds (VOC) in the natural gas and petrochemical industries is going to be more complex than ever in the wake of a recent EPA settlement with a major oil company focused on flare operations. The implications of the this settlement and the VOC emissions study are sure to be far-reaching, likely reducing the use of flares as control devices and increasing the cost of ...

Flare Operations Changes Come From Study Findings
EPA announced that it had reached a settlement agreement with Marathon Petroleum Company (Marathon) regarding allegations of Clean Air Act violations at Marathon’s Texas City and Detroit refineries. EPA developed the evidence by Fourier Transform Infrared Spectroscopy (FTIR) showing that several of Marathon’s flares were not controlling VOC emissions sufficiently, resulting in excess ...

Why high temperature combustion of landfill gas?
Due to the accumulation of knowledge and the tightening of environmental law, the landfill technology has increasingly become concerned with the management of trace compounds in landfill gas. With landfill gas, contamination is through sulphur, chlorine, fluorine, halogenated hydrocarbons and heavy metals. Other trace elements such as volatile organic compounds (VOC), impose environmental ...
