Two power plant schemes that reduce CO2 emission and employ natural gas reforming were analyzed and discussed. The first one integrates natural gas reforming technology for efficiency improvement with an oxy-fuel combined power system (OXYF-REF), with water as the main work fluid. The reforming heat is obtained from the available turbine exhaust heat, and the produced syngas is used as fuel wit...

Introduction Reforming (i.e., partial oxidation, steam reforming, or autothermal reforming (ATR)) of infrastructure fuels, such as natural gas, liquefied petroleum gas, gasoline, or diesel, is one approach being investigated for distributed H2 production for use with fuel cell systems being developed for automotive and stationary applications. One area of interest is reforming gasoline either o...

Sour gas wells frequently co-produce elemental sulfur which can cause catastrophic corrosion of mild steel. As producing wells become increasingly sour, the incidence of sulfur corrosion will likely increase. Despite the severity of this problem, limited mechanistic information about this process exists in the literature. The objective of this study is investigation of the corrosion mechanism i...

In sour gas flares,  content like any other components in inlet gas influences adiabatic flame temperature, which, in turn, impacts on the pollutant emission. Wherever flame temperature increases, the endothermic reaction between  and  is accelerated, which means higher  emission to the atmosphere. In this work, we developed an in-house MATLAB code to provide an environment for combustion calcu...

BACKGROUND Bio-jet fuels compatible with current aviation infrastructure are needed as an alternative to petroleum-based jet fuel to lower greenhouse gas emissions and reduce dependence on fossil fuels. Cradle to grave life cycle analysis is used to investigate the global warming potential and fossil fuel use of converting poplar biomass to drop-in bio-jet fuel via a novel bioconversion platfor...

This paper presents the initial stage of an effort aimed at developing a new correlation to estimate pseudo critical properties for sour gas when the exact composition is not known. Several mixing rules and gas gravity correlations available in the literature are first evaluated and compared. The evaluation is performed on a large database consisting of more than 2000 samples of sour gas compos...

Large amounts of global sources of remote natural reserves gas are identified along with the main objective to allow energy contained in to be moved economically to the market. The current options that are adopted to export natural gas are basically two:1. To liquefy the gas and ship it as LNG (Liquefied Natural Gas). 2. To convert it to bulk petrochemicals in particular methanol or ammonia and...

since the pressure of hydrocarbon reservoirs drops due to production, in order to keep the production rate constant or increase enhanced recovery, few methods are used. one of which is gas injection to the reservoir. on the other hand, due to reduction in oil production potential of aghajari oil field, gas injection is highly required to pressurize and enhance oil recovery. there is a possibili...

With the actual growth of the natural gas industry in the US as well as the potential and availability of this non-renewable carbon source worldwide, reforming of methane gas is getting increasing attention. Methane can be used for the production of heat or electricity, as well, it can be converted to syngas, a building block that could lead to the production of liquid fuels and chemicals, a ve...

Synthesis gas manufacturing by steam reforming of hydrocarbons is an important industrial process. High endothermic nature of the process makes it one of the most cost and heat intensive processes. In the present work, composite effect of different inert gases on synthesis gas yield, feed gas conversion and temperature distribution along the reactor length has been studied using a heterogeneous...
