Natural gas consists mainly of methane (CH4) and other lighter hydrocarbons, but it has traces of contaminants such as carbon dioxide (CO2) and hydrogen sulfide (H2S).

The traditional method for solving this problem is to use experimentation which is time – consuming and expensive. Currently available selection criteria are inadequate.

Liquefied natural gas (LNG) is attracting increasing attention as an alternative fuel in the maritime sector, as it can reduce harmful emissions for compliance with stricter environmental regulations. Owing to this environmental advantage, the number of ships using LNG as a fuel is increasing; thus, the demand for ship-to-ship LNG bunkering is increasing. One of the challenges of ship-to-ship LNG bunkering is boil-off gas (BOG) management, as it is more difficult than normal BOG management. This study analyzed the influences of the parameters on vapor generation, including the temperature diff

The polluting gas flow and emission levels emitted from the Zawia combined Power Plant (ZCPP) in-northwestern Libya were estimated using an Aspen-Hysys v.8.0 simulator which was performed for the plant based on the actual operating conditions of the power plant in steady state operation. Then, the air dispersion modeling tool (Disper V4.0 software) was used to estimate the concentration of these pollutants emitted throughout the surrounding areas, and the WAR algorithm v.1.0.17 was used to check the potential environmental impacts of the gas emissions from ZCPP.

Résumé :

Biomass gasification is an attractive technology and one of the pathways for producing hydrogen. Due to the variable seasons and low calorific value of biomass, the addition of coal in the gasifier is suggested because coal has a high calorific value and carbon-to-hydrogen ratio. In general, the gaseous product obtained in gasification always contains a high amount of carbon dioxide, therefore, the co-gasification of biomass and coal should integrate with the calcium looping carbon dioxide capture process to provide purified hydrogen. In this work, the model of the co-gasification of biomass a

Introduction. Flaring of gas in flares is one of the main factors of global warming and climate change. Flaring is inevitable and is an integral part of technological processes as a measure to ensure their safety and continuity. On the other hand, flare gases, in particular methane gas flows from coal mines, are considered as high-value products that can be used as raw materials for the production of synthetic fuels and hydrogen.

Résumé :

AbstractCarbon capture utilization and storage‐enhanced oil recovery (EOR) is often considered the most promising technology for utilizing CO2. Cryogenic distillation is also viewed as the most reasonable separation option for handling CO2‐EOR gases, despite being an energy‐intensive process. The main challenge for this technology is energy loss. To overcome this challenge, one potential alternative is to optimize the system processes and parameters. This study proposes a new process to reduce distillation energy consumption by refluxing the distillate back to the distillation column. Operatio

Dimethyl ether is a colorless compound possesses a heating value of 30,5 MJ/kg and an energy equivalency with LPG ranging between 1,56 – 1,76. Dimethyl ether can be directly synthesized from synthetic gas produced through natural gas reforming.

This work distinguishes from others by seamlessly integrating masked agents with rigorous unit operations (UOs) models, that is, adv

Background: One of the most challenging aspects of coronavirus disease 2019 (COVID-19) is that a newly infected individual shows diagnosable symptoms, such as body temperature (Tb) rise, several days after contracting the disease. In the early phase of infection (i.e., incubation period), an undiagnosed and unaware individual can spread the virus to others. The fastest and most efficient route of COVID-19 transmission is the respiratory system. Therefore, developing a model of the respiratory system to predict changes in the lung performance upon COVID-19 infection is useful for early diagnosi
