Gas Recovery

The object of research is gas condensate reservoirs, which is being developed under the conditions of the manifestation of the water drive of development and the negative effect of formation water on the process of natural gas production. The results of the performed theoretical and experimental studies show that a promising direction for increasing hydrocarbon recovery from fields at the final stage of development is the displacement of natural gas to producing wells by injection non-hydrocarbon gases into productive reservoirs. The final gas recovery factor according to the results of laboratory studies in the case of injection of non-hydrocarbon gases into productive reservoirs depends on the type of displacing agent and the level heterogeneity of reservoir. With the purpose update the existing technologies for the development of fields in conditions of the showing of water drive, the technology of injection carbon dioxide into productive reservoirs at the boundary of the gas-water contact was studied using a digital three-dimensional model of a gas condensate deposit. The study was carried out for various values of the rate of natural gas production. The production well rate for calculations is taken at the level of 30, 40, 50, 60, 70, 80 thousand m3/day. Based on the data obtained, it has been established that an increase in the rate of natural gas production has a positive effect on the development of a productive reservoir and leads to an increase in the gas recovery factor. Based on the results of statistical processing of the calculated data, the optimal value of the rate of natural gas production was determined when carbon dioxide is injected into the productive reservoir at the boundary of the gas-water contact is 55.93 thousand m3/day. The final gas recovery factor for the optimal natural gas production rate is 64.99 %. The results of the studies carried out indicate the technological efficiency of injecting carbon dioxide into productive reservoirs at the boundary of the gas-water contact in order to slow down the movement of formation water into productive reservoirs and increase the final gas recovery factor.

Anaerobic digestion is one of solution to environmental problems and energy sources for current energy needs. In anaerobic digestion, organic material is degraded by bacteria, which is carried out without oxygen, and converts it to a mixture of methane and carbon dioxide. POME can be degraded anaerobically in anaerobic digester to produce biogas. This study aims to increase the conversion of biogas produced using a 2 liter Continuous Stirred Tank Reactor (CSTR) type digester in the methanogenesis process by recycling the effluent produced through the ultrafiltration membrane in a transition condition (45oC). The process is carried out by varying the recycle ratio, which is 0%, 15% and 25% on HRT 6 days with a condition of pH 7 ± 0.2. The highest average biogas production was achieved at the 25% recycle ratio of 33.15 x 10-5 L / mg VS. day, with the composition of methane, carbon dioxide and hydrogen sulfide each of 79%; 19%; and 0.006%, with degradation of VS and COD of 39.58% and 66.33% respectively. For the composition of the highest CH4 content obtained at a variation of the 15% recycle ratio which is equal to 85% while for the composition of carbon dioxide, and hydrogen sulfide each is 14%; and 0.0076%.

Biogas Purification

<p>Purifying biogas from CO2 (carbon dioxide) and H2S (hydrogen sulfide) needs to be done to improve the quality of the biogas in the fuel. The presence of H2S in biogas can cause corrosive to the equipment, in addition to this, H2S is also dangerous for human and animal health. CO2 contained in Biogas is also an impurity that can cause corrosive beside H2S so the contained in biogas is also an impurity that can cause corrosive, so the purification process needs to be done in order to qualify biogas as natural gas which environmentally friendly and safe for health. The basic ingredient of biogas purification using water scrubbers base ingredients are water, which flowed pressurized biogas purification column from the bottom, of the column in order to reduce CO2 and H2S gases. The result of purification by using this method was that the levels of H2S in biogas reduced by 32.8 % while the CO2 content decreased by 21.2 %. It can be concluded that the H2S gas more soluble in the water compared with CO2, as H2S gas has higher efficiency removal from CO2. </p><p><strong>Keywords</strong>: biogas; carbon dioxide; hydrogen sulfide, waters scrubber</p>
