The oil field at Majdan, Serbia had excess Assosiated Petroleum Gas (APG). Due to the low heating value and high CO2 content, this gas used to be flared. In 2016 RSE installed a fully containerized power plant with 5 units ENERGIN GEN G500 installed in three containers. The gas cleaning system to remove traces of siloxanes and H2S was also supplied by ...

The Characteristics of silicone electrical insulation Product1. Heat and Cold ResistanceSince silicone rubber has high bond energy and good chemical stability, its heat resistance is better than that of organic polymers. Furthermore, since the intermolecular interaction force is weak, the glass transition temperature is low and the cold resistance is also good. Therefore, its properties will not ...

For the adequate use of biogas as biofuel in CHP-equipment or for biomethane production, it requires a previous conditioning to remove or reduce all of the dangerous compounds. Biolimp-siloxa is a multi-purpose plant technology to consider in reducing all pollutants. Biogas is a gaseous mixture formed mainly by methane (CH 4 ), CO 2 and traces of other components. Biogas has dangerous compounds ...

We investigated the behaviour of siloxanes, which adversely affect biogas engines, as well as their concentration levels in sewage sludge biogas in Japan. We also performed experiments on the absorptive removal of siloxanes using various adsorbents and determined the main adsorbent characteristics required for the removal of siloxanes. The results of our study on the concentration and composition ...

Abstract Anaerobic digestion is quickly becoming the choice technology for sewage sludge treatment at wastewater treatment plants, as the methane rich biogas produced is a valuable resource which can be used to generate electricity. In the oxygen restricted environment, a natural by-product of the anaerobic process is hydrogen sulfide, a harmful contaminant. Also present in the biogas are ...

In a recent white paper, Restek corporation identified a simple methodology for the simple comparison of e-cigarette liquids using GC-MS and GC-FID. E-cigarettes have been a fairly recent phenomenon. An alternative to smoking tobacco, e-cigarettes work by vaporizing a liquid which is then inhaled by the user. Despite only being available to the market for a few years, e-cigarettes are thought to ...

The biogas produced in a digester, landfill or waste water plant is normally treated in order to remove water, H2S, dust and/or CO2. The choice of the cleaning method employed and the compound to be removed depends on the type of end use of the gas. This paper focuses on desing, star up and operation of biogas cleaning plant for removal dangerous component (water, H2S, NH3, siloxane and ...

Siloxanes present in the biogas produced during anaerobic digestion in wastewater treatment plants (WWTPs) can damage the mechanism of cogeneration heat engines and obstruct the process of energy valorization. The objective of this research is to detect the presence of siloxanes in the biogas and evaluate a procedure for their elimination. A breakthrough curve of a synthetic ...

Reducing the carbon footprint of our society is essential. This can be achieved by capturing and confining anthropogenic CO2 emissions, as well as by replacing fossil fuels with renewable fuels. MCFCs (Molten Carbonate Fuel Cells) are the only ones capable of doing both. Thanks to their principle of operation, CO2 can be extracted from a gas stream on the cathode side and fuels such as biogas ...

As a type of biofuel that not only eliminates waste but also produces a valuable energy source, biogas production has increased in recent years. According to the US Energy Information Administration, biogas contributed to approximately 11.5 billion kilowatt-hours of electricity back in 2017. However, biogas can be only be produced in an anaerobic environment without oxygen. This is a very ...
