This project aims at providing smart solutions to monitor poisonous sewage gases and works on a system of live sewage level detection and monitoring. Whenever, a certain threshold is crossed, an alert is sent to the observer who is examining the conditions from a remote location. The information is then forwarded along with different gas ppm values indicating whether it is safe for the worker to clean or work in that environment or not. The remotely placed IoT monitoring equipment and IoT platform are integrated to create proposed system. This requires calibration of gas sensors for industrial purposes and determining the correct threshold levels for septic plants and facilities. The hardware is designed such that it shall send a prior alert to the sewage worker to ensure their safety, if damaging gaseous constituents increase in concentration over time. Various types of sensors are utilized to monitor parameters present in sewage like gas, temperature etc. When the threshold value is lesser than the sensed values, this system alerts the sewage worker/cleaner by sending SMS and call alerts by analyzing concentrations of different toxic gases and graphing out their results for real-time monitoring thereby aiding in protection from hazardous diseases and hence serves a social cause as well. In the proposed system, sample values for sensors have been recorded and plotted on ThingSpeak analysis tool. Carbon monoxide and methane sensors charted values up-to 2.3 and 60 ppm respectively, and this breached threshold and GSM module was utilized for sending alert to mobile number fed in the code.
Isotopic measurements of methane are very important for environment. The level of gas in the atmosphere has significant impact on its radiative forcing, increase is estimated to 0.48 W/m2since pre-industrial times . Isotopic ratio of carbon in CH4provides information about the origin of the gas. The recent development of compact interband cascade lasers (ICLs) permits the targeting of strong fundamental rotational-vibrational transitions absorption lines at room temperature conditions with wide wavelength span. Therefore it is possible to build compact, robust, field deployable gas sensors .
Underground mines are more hazardous in nature and contain unsafe zones for their workers. There is the need to develop an effective, secure, reliable and low cost surveillance and safety system in underground mines. This paper presents a low cost, low power mobile wireless underground mine environment monitoring system, developed by using the ZigBee protocols based wireless data transfer system. The system includes a small board integrating all sensors designed for monitoring the underground environment. Suitable firmware is developed for secure and reliable wireless data transfer from the sensor network. Data, transferred through routers and coordinator is received by data management & acquisition software, developed for the purpose. This helps in displaying the real-time data in tabular and graphical forms as well as for alarm generation in case of exceeding the limits. The whole system is tested in a model mine successfully.
In cold regions, because the heat demand is high in winter, greenhouse gas emission is an issue. In this study, we propose a new power generation system using a CO2 hydrate. This system uses the pressure variation properties of the CO2 hydrate under temperature changes. However, since the production speed of the CO2 hydrate is basically slow, efficiency of heat cycle of the system is decreased. Before now, increase in gas absorption of the CO2 hydrate is confirmed by using mixed powder of hematite and graphite (afterward iron oxide catalyst). Increase in gas absorption of the CO2 hydrate contributes to improvement for the efficiency of heat cycle of the CO2 hydrate. The subject of the present research devise improvement of the contact probability of three-phase interface of the CO2 hydrate for further improvement of gas absorption by microstructural carbon cloth support iron oxide catalysts.
There are certain areas that have risks that require doing some measurements. A typical area is sanitary landfill site where there is need to monitor gas concentration periodically even after it has been closed for many years. In this paper, we will develop a sensing system having the ability to measure the gas concentration in a landfill site, and we will focus on the type of gas distribution with respect to the gas emission source. Also, we will try to present a method to prove that our sensing system will be reliable.

Hazardous gases like propane and methane are combustible and could cause explosion if confined in a close room. The study described in this paper comprises a system that involves detection and notification of hazardous gases present in an area. The system has three sensors; hydrogen sensor, Liquefied Petroleum Gas (LPG) sensor, and methane sensor that serve as switches with different set-points. Every level of gas detected is send to the Arduino that serves as the controller which analyze the level of gas present. The controller is also in charge for triggering the lamp, exhaust fan, buzzer, Liquid Crystal Display (LCD) monitor and Global System Mobile (GSM) module. The system has three lamps that indicate the level of gas being detected. Green light means “safe level”, yellow means “medium level”, and red for “danger level”. The exhaust fan is activated as the controller detects medium level, which is simultaneous with the lighting of the yellow light and will only be deactivated when the system detects again safe level. The buzzer is activated as the controller detects danger level which is synchronized with the lighting of the red light. The LCD monitor displays the level of gas being detected and the GSM module sends Short Message Service (SMS) as notification to concern people. The system was tested and is capable of detecting LPG, methane gas and hydrogen gas with a maximum distance of 50, 30 and 30 inches, respectively.
Animal waste generated in farms of developing countries is usually handled through stockpiling and direct application to soil. However, there are negative environmental impacts associated with those practices, mainly contribution to global warming, eutrophication and odor. Anaerobic digestion is one of the well-established technologies that capture the energy in the waste, including animal waste. In this research, manures from different types of cows typically present in dairy farms were collected and tested for their biochemical methane potential. The test was conducted on five categories of cows, namely: (1) high cows; regularly milked cows, (2) dry cows; pregnant cows, (3) fresh cows; to be milked for the first time after their delivery, (4) young cows (Young-1); cows younger than 18 months, and (5) young cows (Young-2); cows younger than 7 months. Those cows differ in age, weight, digestion/ metabolic processes and feeding diet, which lead to variations in biochemical characteristics, and consequently biogas potential, of the produced manure. The methane yield was found to be highest in the manure of fresh cows (216 L CH4/kg VS), followed by Young-1 (208 L CH4/kg VS), high (196 L CH4/kg VS), dry (160 L CH4/kg VS), and Young-2 (148 L CH4/kg VS) cow manures. The carbohydrates, lipids, and proteins were measured for each manure type to determine their effects on biogas production. Furthermore, those parameters were tested for correlation with the measured biogas production using Kendall's Tau approach. The analysis showed that higher lipid and protein contents lead to lower biogas potential, while higher carbohydrates content resulted in higher biogas production.

Summary form only given. The kinetics of plasma-assisted catalytic conversions for hydrocarbons involve complicated surface reaction dynamics, resulting from multiple, different contributors . Aside from direct catalyst-plasma interactions that are expected to drive the catalytic event [2, 3], other feasible sources are C-H bond excitation in the plasma itself, packed-bad charge confinement modifying the plasma dynamics, and local catalytic spots heated by the plasma (i.e., background contributions). This presentation will discuss our efforts at precisely evaluating the kinetics of catalyst-plasma interactions to activate C-H bonds by employing dry methane (CH4) reforming on a catalytic nickel (Ni) surface as a model reaction. In a reaction-limited regime at ≥790 K, interactions between accessible Ni sites and excited CH4species (NiCH4*) are quantified via forward CH4consumption rates under a controlled reaction environment. A series of surface reaction elementary steps are also proposed and used to derive a reaction rate law, all of which are validated via control reaction runs. In particular, we find that a modified form of the Arrhenius equation can be used to extract energy barrier required to reform CH4species caused mainly by NiCH4*. The resulting energy barrier is smaller than the activation energy found in conventional thermal catalysis. These results suggest that the catalyst-plasma interaction lowers the energy required to activate C-H bonds.
