Composition of Synthesis Gas Produced by …

AB - Electrophysical intraformational gasification of coals from the Egozovo-Krasnoyarsk, Krasnogorsk, and Balakhta deposits was investigated. The quantitative composition of the synthesis gas was determined. Its heats of combustion at various heating rates were calculated. It was found that the concentrations of H2 and CO2 in the obtained synthesis gas decreased whereas that of CO increased if the heating rate was accelerated. The results showed that accelerating the heating rate increased slightly the heat of combustion because the decreased H2 and CH4 concentrations were compensated by the increased CO concentration.

[0013] the Ratio between hydrogen and carbon monoxide in the synthesis gas is called the ratio of H2/CO in the syngas, and this value strongly depends on the applied method and nature of raw materials.

Regulation of synthesis-gas composition in installation …

Carbon monoxide and hydrogen is produced in UPRM in the application of steam and methane as the raw feed. The heating of service water in the steam generator allows to obtain the desired vapor. Methane is usually served in the form of compressed natural gas or low-molecular flow of exhaust gases resulting from chemical process or the cleaning process.

[0018] the present invention proposes an improved, economical alternative way of steam and methane at UPRM and controlling the composition of the synthesis gas obtained on UPRM. The proposed method is implemented by combining new technological ways in which the product gas (product gas) from the RPG used as Ref�defined raw materials for UPRM after removing impurities from the product stream, the incoming RPGs, the installation for purifying gas, which is operating at working pressures and is located between RPG and UPRM.

[0011] There are several methods for the conversion of biomass and other carbonaceous materials in a cleaner-burning transportation fuels, but they are too expensive to compete on the market with fuels derived from crude oil, or they produce volatile fuel, such as methanol and ethanol, the saturated vapor pressure which is too high for use in highly contaminated areas, such as air basin of southern California, without statutory easing regulatory requirements of clean air. An example of the latter method is a method of producing methanol from quinol to use reactors for hydrogasification and for steam reforming to synthesis of methanol by applying jointly supplied raw materials consisting of solid carbonaceous materials and natural gas, and proved the efficiency of conversion of carbon in which is >85% at poster demonstrations.

This process is known as methanation. A gas is obtained of typical composition: 74% hydrogen, 25% nitrogen, 1% methane, together with some argon.

Produced waters. Produced waters usually include dissolved salts and organic compounds, oil hydrocarbons, trace metals, suspensions, and many other substances that are components of formation water from the reservoir or are used during drilling and other production operations. Besides, produced waters can mix with the extracted oil, gas, and injection waters from the wells. All of the above make the composition of the discharged produced waters very complex and changeable. It is practically impossible to speak about some average parameters of this composition, especially because reliable and complete analytical studies of these wastes are very rare.

Waste discharges during the offshore oil and gas activity

[0012] the Synthesis gas can be obtained by using one of the two main chemical processes: steam reforming and partial �of celenia. Steam reforming is used when the starting material consists of light hydrocarbons such as natural gas, and when hydrogen is the main product. Partial oxidation is used with heavier materials supplied or require a relatively high yield of carbon monoxide. Table 1 shows various industrial methods in operation for producing synthesis gas [1].

[0031] According to another embodiment implementing the present invention proposes an improved, economical method of controlling the composition of the synthesis gas obtained in the steam reforming of methane, which serves the feedstock in the form of product gas directly from the reactor to the steam hydrogasification. The proposed method allows you to adjust the ratio of N2/WITH by pre-setting/adjusting the hydrogen supply water content in the feedstock entering the RPG, which provides UPRM. According to a particular embodiment of the invention, the molar ratio of H2/CO of about 0.5:1 to 16:1 and in particular from about 1:1 to 6:1, can be obtained as a result of adjustment/pre�preliminary installation of hydrogen supply and the water content in the feedstock, coming in an RPG.
