Abstract
The thesis presents the assessment, identification and quantification the main sources of CO2 emissions and proposes emission abatement opportunities. The assessment was based on reviewing the previous studies related to the plant such as Environmental Impact Assessment (EIA) studies including all phases of the projects, safety & operational cases, hazard operability studies (HAZOP) and preliminary energy assessment studies, process operations as well as reviewing the plant flow diagrams, P&IDs and the production daily reports. The assessment revealed that the gas industry is one of the significant sources of CO2 emissions in Egypt. The facility under study produces 510,677 tonnes of CO2 per year. There major CO2 producers include; the main power generation turbines, the regeneration heaters, hot oil heaters, onshore & offshore diesel driven equipment and the flares. Nine management opportunities are devised and verified by using API modeling equations and Emissions Forecaster software; six are relating to change of the operational modes and three of them are involving modifications on the equipment or replace them that result in savings in consumption and in turn result in less CO2 emissions. The devised opportunities are including Compression scenarios, Flared gas reduction, adjusting silica gel regeneration cycle, flash gas compression operation project, calibrate oxygen analyzer in heater stack, car-pooling initiative, Power optimization, use of energy saving lamps and equipment, and replacement of damaged flare tips and ignition system. The results of the modelling and forecaster software showed that the total savings is more than 50% reduction of the total tCO2 emissions from the whole processing facility. It is the opportunity to recommend the application of these opportunities to all natural gas processing facilities of natural gas production companies, which do not differ greatly in their design from the processing facility at which the study was applied.
