“…The results showed that, in the best flare gas recovery model solution, electricity is the lowest amount of product obtained annually against LPG and condensate products [16][17][18][19][20][21][22] evaluated in several papers' different methods and substances for gas treatment, considering the mitigation of greenhouse gases, and testing the effectiveness of these methods. Shayan et al [23,24] simulated FGR methods in ASPEN HYSYS, and the results show that the electric power produced by steam turbines (7.323 × 10 5 kW), electricity and heat generation (4.350 × 10 5 kW), and [6], 2019 [4], and until October 2020 [7] for the Colombian basins reported for the ANH.…”

“…The authors calculated the average energy requirements in the equipment that needed to be supplied, concluding that the associated gas was more than enough to supply the energy required. As a conclusion, the authors reviewed the energy generation equipment that can use natural gas as fuel and different associated gas separation technologies and wrapped up by presenting that using the flaring gas for rig equipment and hydraulic fracturing operations are cost-saving [4][5][6][7][8][9][25][26][27][28].…”

“…That is why it is important to identify alternatives for reducing the flaring of these components by the recovery and reuse of this resource and satisfy the world bank initiative "Zero routine flaring by 2030" [2][3][4][5][6][7]. In this work, the investigation of alternatives to reduce the amount of flaring gas in Colombia is expanded and goes in favor of the Ecopetrol Commitments for the decrease of greenhouse gases emissions and also contributes to the "Colombian Strategy for the low carbon development" (ECDBC for its acronym in Spanish); this government strategy plan seeks to mitigate greenhouse gases emissions during the country's economic growth.…”

“…By the gas production reports presented by the Colombian hydrocarbon national agency (ANH for its acronym in Spanish) for 2018, 2019, and until October of 2020, the sedimentary basin that has the higher percentage of flaring gas was the "Llanos Orientales (LLO)" basin, followed by the "Valle Medio del Magdalena (VMM)" basin. The Figure 1 presented below shows the percentages of produced gas, flared gas, and transformed gas in the years for the Colombian basins reported for the ANH [5][6][7][8][9].…”

During petroleum industry operations, burning flammable gas components in the flaring stacks is common, normally a symbol for stable production, but flaring these components creates harmful emissions for the environment. This flaring gas has components with a high quantity of heating power, an important measurement that quantifies the energy that can potentially be obtained from this wasted resource. This paper aims to evaluate the energy usage of the flaring gas, estimating the possible energy produced with this usable resource by modeling a treatment and energy generation process employing the Aspen HYSYS® simulator. The flaring gas is characterized using different models and compositional ranges of natural gas to know what kind of gas it is and identify what type of equipment could be used for treatment and energy generation from this resource. After the gas characterization, the selection of the equipment of treatment and energy generation is necessary; this is done using a multicriteria analysis by taking into consideration the variables of gas composition, electrical efficiency, economic performance, and GHG emissions, ensuring to generate the greatest amount of energy possible to be produced with this flaring gas. By increasing the LHV, 0.95 MMSCF of flared gas of an oilfield in the VMM basin produced 5133 kW, enough energy to supply gas treatment and power generation facilities and four times the total gross consumption energy of a model oilfield in the basin, while the CO2 emissions were reduced 11.4%, and cost savings using this resource instead of diesel were obtained. In conclusion, to minimize flaring and to recover and reuse these waste components, looking for alternatives for the use of this gas-like power generation is an important option that reduces pollutants emission, gives a new source of fuel, and gives an energy usefulness to this wasted resource.

“…Lately, studies related to the natural gas supply chain models deals with different optimization models. For example, Becerra-Fernandez et al [3,4] used system dynamics modeling to present the natural gas supply chain in Colombia. The results allow them to compare the behavior of production and transport levels on the one side, and the behavior of the demand on the other side.…”

The purpose of this study is to develop a natural gas simulation model for costs optimization. The main focus of the model is on the transmission system since its imbalance leads to the penalties which must be paid by the suppliers. The total nominated amount of natural gas (the gas injected into the transmission system) must be consumed (withdrawn from the system) in order for the system to be in balance. In practice, this is not the case since it is very hard to accurately predict the future hourly consumption (in order to make a nomination) and certain deviations appear which leads to the imbalance. However, this problem could be solved by introducing a special electromotor valve which would be placed at the beginning of the distribution system and control the accumulation of the system. To test this solution, a simulation model was created using Arena Simulation tool. Data for the simulation model are collected by the natural gas distributor and consist of natural gas consumption and nomination values for one measuring-reduction station on the hourly basis. Thus, the final dataset includes 8.754 records. The separate As-Is and To-Be models for seven (summer) months were made and the results were compared. The simulation experiment shows that the positive rebalancing energy would be reduced by 32%, and the negative one by 34%. The created model can serve as a good initial step for the analysis of the justification of investment in the implementation of a technical solution that would manage the accumulation of the distribution system.
