Top of Line Corrosion (TLC) Behaviour with Presence of Gas Condensate in CO_2 Wet Gas Pipeline

In a stratified flow scheme, line corrosion in the CO_2 wet gas pipeline is a significant threat to the oil and gas industry, where a difference in internal pipe temperature and outside environment leads to condensation of water in a stratified flow system. Gas condensate is usually present in pipelines in the oil and gas industry. This condensable hydrocarbon may have an effect on condensation process because it is immiscible with water, resulting in differing wettability on the pipeline surface. TLC testing with and without gas condensate was conducted in this study to determine the effect of gas condensate on the water condensation rate and the TLC rate. The presence of gas condensate in the system resulted in a 62% lower WCR compared to that of a gas condensate-free system with the same temperature difference between gas and steel, resulting in a 62% lower WCR. With a difference of 33%, the TLC rate was found to be higher in a gas condensate-free environment.

Energy and Exergy Study of a Compression Ignition Engine Running with Producer Gas

The exergy characteristics of a dual-fuel diesel engine were determined under the goal of obtaining the highest diesel savings in the current study. As pilot fuel, a 10% volume blend of Karanja oil methyl ester with diesel was considered as pilot fuel.

Recovery of Iron Values from Blast Furnace Gas Cleaning Process Sludge by Medium Intensity Magnetic Separation Method

A sludge produced by steel plants' industrial wastewater, which contains a significant amount of iron and carbon, which can be recovered and reused. The present study examined the granular separation of iron values from the gas cleaning process sludge of varying intensity and determined the degree and recovery.

Simulation of Natural Gas Combustor Using CFD

Natural gas is used by the natural gas combustor as a fuel for the combustion process. Several styles of natural gas combustors are available for the above-said process; the configuration of the combustor is determined based on the application. In two separate simulation programs, the current research is geared toward the CFD simulation of natural gas combustor using the Species Transport model, as well as different Turbulence models and Radiation simulations. In Ansys Fluent, the above-mentioned combustion, radiation, and turbulence models are used to perform fluid, thermo, and combustion analysis of natural gas combustor.

DSC and TGA Investigation on Ammonium Nitrate-Based Solid Propellant Doped with Ammonium Dichromate for Gas Generator Applications

On ignition, a typical solid propellant gas generator will produce gas-phase combustion products and particulates that leave the generator through an exhaust line. The combustion products are highly concentrated and temperature, and they can be tapped from the gas chamber to control the actuator system. This paper is intended to investigate Ammonium Nitrate-based gas generator propellants that are most suitable for low flame temperature and chlorine-free combustion products. Ammonium Nitrate is particularly effective for a slower burning rate and low flame temperature. Five separate propellant compositions were developed and evaluated the effect of ammonium dichromate on propellants. STA was used to determine decomposition temperature from the DSC curve and mass loss from the TG curve for thermal analysis. Through this study, ADC and GN's influence on the decomposition and thermal behavior of propellants has been investigated.

Study of a Low Cost and Wearable Gas Sensor for Safety of Workers and Workplaces

This work depicts the first characterization effort for the gas sensor candidate. Metal Oxide Gas Sensors are the most useful gas sensor typology due to their miniaturization and high sensitivity. ST microelectronics manufactured a miniaturized MOX prototype that can be tested and optimized for the Project. Response to humidity also measured under an environmental humidity change; response to humidity is also assessed.

An Attention-GRU Based Gas Price Prediction Model for Ethereum Transactions

To determine the influence factor, we used the gated recurrent unit neural network to determine the gas price prediction based on previous studies. Based on previous study, we discovered influence factors of block gas upper limit, transaction gas upper limit, and mining difficulty that cause gas price fluctuations, as well as the attention mechanism to obtain the weight of the influence factor. The predicted gas price prediction method, which is based on 2000 real blocks, has high resolution and repeatable results, saving consumers a significant amount of transaction costs; because the correct gas price can be predicted, the success rate of usersu2019 transactions has increased by 21. 9 percent.

Rrenewable Natural Gas as a Greener Energy Source: A Life Cycle Cost–Benefit Analysis

Natural gas supplies account for more than half of Canada's electricity and heating demand. However, a comprehensive study is required to determine the incremental gains and costs of replacing conventional NG with RNG in the key carbon-intensive applications of the energy sector. This report conducted scenario-based life cycle economic and economic evaluations to determine the costs and benefits of replacing the conventional NG system with RNG and other alternative residential building heating technologies. The study was further extended to determine the suitability of replacing NG with RNG-based and other building heating technologies in Canadian provinces that depend heavily on NG to consider the effect of regional parameters on decisions related to building energy infrastructure. The results of this report are intended to encourage decision makers and investors to gain a more holistic view of investment decisions related to renewable energy initiatives in building green energy infrastructure.

Numerical assessment of performance characteristics and two-phase flow dynamics of a centrifugal rotor operating under gas entrainment condition

This work includes a numerical investigation of the performance characteristics and flow dynamics of a centrifugal rotor operating with gas-liquid flow. In particular, an investigation of the rotor head components is carried out, as well as the dynamic head examination through the rotor, which is often overlooked in most studies. This includes an investigation of the three-dimensional distribution of the gas phase inside the rotor, analysis of gas-liquid interphase forces, and the effect of the intake gas flow rate on the bubble diameter, gas-liquid relative velocities, and overall turbulence levels through the rotor.
