<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>

The dependence of human being on fossil fuels has decreased significantly the conventional energy resources. To overcome this problem it is required alternative substitute fuels which are cheap and accessible which biogas is one of the fuels. Nevertheless, the use of biogas has not yet been maximized because of the low calorific value which is produced from the process without purification. The circulated water absorption method is one mean of effective biogas purification. Under this method it is expected to increase the level of methane (CH4) and to reduce both the level of carbon dioxide (CO2) and hydrogen sulfide (H2S). In order to obtain the aim, the research was carried out under variations of water and biogas volumetric flow rate. The results show that the highest quality of biogas produced was under the variation of water volumetric flow rate of 15 lt/min with biogas volumetric flow rate of 1 lt/min which increased the level of methane (CH4) from 59.36 % to 62.8 % and decreased the carbon dioxide (CO2) content from 33.53 % to 26.8 %, and hydrogen sulfide (H2S) from 208.33 to 86 ppm. Lower biogas and water volumetric rates allowed longer contact between biogas molecule and absorbent. This resulted in an opportunity for absorbent more active to dissolve carbon dioxide and hydrogen sulfide in biogas. These compounds then flowed outward of the scrubbing unit along with the absorbent. The research proved that the raw biogas purification by circulated water scrubbing method was an effective mean in enhancing the quality of biogas.

A large fraction of the global natural gas reserves is in the form of sour gas, i.e. contains hydrogen sulfide (H2S) and carbon dioxide (CO2), and needs to be sweetened before utilization.

Natural gas of GMS (Gas Metering Station) is an important component that must be analyzed routinely in PT. Fertilizer Sriwidjaja because it is the main material used in addition to Carbon dioxide (CO2) and water vapor in the manufacture of ammonia. The quality of natural gas will affect the ammonia and urea fertilizer product. The purpose of this research is to know the composition of hydrocarbons and to know the level of H2S gas in natural gas which is contained in GMS pipes. Determination of H2S levels was performed to find out the many catalysts used in the manufacture of ammonia gas.In determining the hydrocarbon composition, the first gas sample is taken using Stainless Steel Cylinder Tube. After the gas filled tube it was analyzed using GC (Gas Chromatography) and  it will know the hydrocarbon composition of GMS. As for the determination of H2S level, the gas sample taken as much as 30 L through gas spreader and inserted into erlenmeyer with 10% Cd Acetate and NaOH. Subsequently, 1% PADAS (N, N-Dimethyl-p-phenylendiamine sulphate) and FeCl3 were added. After the solution changed to blue color then analyzed using UV-Vis Spectrophotometer in 660 nm wavelength.The results obtained are nitrogen-containing natural gas and various hydrocarbon components: methane, hexane, carbon dioxide, ethane, propane, i-butane, n-butane, i-pentane, and n-pentane with H2S 2,954 ppm with the largest composition of methane 85.89%. The results have been in accordance with the standards used in the Pusri Industry which apply the provision that the natural gas used should contain methane with concentrations greater than 70%

Natural gas of Tazhong-1 gas field contains 7.7% carbon dioxide and 2.31% hydrogen sulfide, and produced water salinity is up to 140000mg/L,the well-bore tube has seriously potential corrosion destructive with natural gas being exploited. Based on the corrosion type partition of down-hole tube for eighteen production wells of Tazhong-1 gas field, P110,P110S and P110SS corrosion behavior were investigated under the conditions of simulated formation water containing carbon dioxide or hydrogen sulfide/carbon dioxide, and corrosion inhibitors were chosen to meet need of anticorrosion of Tazhong-1 gas field. The results show that fifteen wells in eighteen production wells belong to hydrogen sulfide corrosion of both hydrogen sulfide and carbon dioxide influence. Other wells are singular carbon dioxide corrosion. The most severe corrosion of three types of down-hole tubes all occurs at 90°C in both corrosion media, and their corrosion resistance order is respectively P110>P110S>P110SS and P110S>P110SS>P110 under the conditions of simulated formation water containing carbon dioxide or hydrogen sulfide and carbon dioxide. The selected anti-temperature corrosion inhibitors (YU-1、YU-4) can control the corrosion rate of three types of down-hole tubular goods within 0.076mm/a in simulated formation water media with carbon dioxide (PCO2=0.08~4.64MPa) or hydrogen sulfide and carbon dioxide (PH2S/Pco2=1.3/4.64Mpa) while added amount of the inhibitor is 120~300mg/L or 200mg/L. All of these provide technical support for safe and fast development of Tazhong-1 gas field.
