AbstractNovel solvents named deep eutectic solvents (DESs) have been intensively investigated in recent years. Their non-toxicity, biodegradability, low volatility, easy preparation and low cost make them promising green solvents for several industrial processes. This article provides a status review of the possible applications of DESs in natural gas (NG) sweetening by carbon dioxide (CO

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>
