Abstract
It is known that the global warming is a serious problem that faces the world nowadays. Climate change presents a global systemic risk to the society. The emissions of greenhouse gases such as methane, carbon dioxide, etc. are the main reasons for increasing the global mean temperature with a high acceleration. Governments started thinking in a positive way and they realized that a very urgent action is necessary to decrease greenhouse gases emissions. The cost of reducing this emissions now is too much lower than the cost of reducing emissions in the future when more cumulative concentrations has been done .The present study discusses how to reduce the emissions of carbon dioxide (CO2) which is one of the main greenhouse gases using different methods for reducing CO2 concentration in the atmosphere. It shows four techniques (CO2 as a chemical feed stock, enhanced oil recovery, CO2 turbine power generation and CO2 storage in the geological formation) that can be used in utilization of extracted CO2 from flared gases. The case study of the present work is directed to the modification of Salam gas & oil plants (Khalda Petroleum Company in Egypt) to prevent the emissions of CO2 from the existing gas plant and oil plant in the field .Salam field produces around 34 MMSCFD of flared gas with CO2 concentration in this stream nearly 73%, so around 25 MMSCFD of carbon dioxide is going to flare from each train which is undesirable for the environment .In the case study, it has been discussed how to capture the CO2 from the flared gas stream and how to utilize the extracted CO2. Capturing CO2 can be done by three main techniques (Absorption process, adsorption process and low-temperature distillation process). Using CO2 stream in enhanced oil recovery (EOR) is the most applicable option in our case study because there are many depleted wells in Salam base that can be suitable for EOR technology, so will get great revenue from the recovered oil. The II simulation tool used in this study is HYSYS version 8.3. The economic study based on the economic analyzer of HYSIS. The main benefit of this suggestion is that it provides zero flare in Salam base and in the same time use the extracted CO2 stream to produce oil from the depleted wells.
