... Abstract Exergy is a simultaneous measure of the quantity and quality of energy. This helps to identify the inefficiency of the process and allows engineers to determine the cause and magnitude of the loss for each operating unit. Natural gas dehydration via absorption using glycol is the most...

... of dehydration plant. In this paper, we highlight the simulation of a natural gas dehydration process which has an inline glycol injection system and then compare its efficiency with the conventional dehydration system. The cost of setting these two units is also compared. The simulation study shows...

... temperature without hydrate formation. As a part of the global downstream pipeline and plant optimization program, Saudi Aramco has invested $65MM capital expense for triethylene glycol (TEG) dehydration unit (3,4,5) at the world largest oil stabilization facility to reduce the frequency of pipeline scraping...

... Abstract A report is presented on natural gas dehydration performance of dehydration units in two different plants using a pre-inhibited glycol/antifoam/pH adjuster blend versus neat glycol with periodic injection of anti-foam and pH adjuster inhibitors. To investigate the effect of using pre...

... to recompress or use the recovered gas. The Methane Source The oil and gas industry dries natural gas to pipeline specifications in oil and gas fields with about 20,000 glycol dehydrators. These glycol dehydrators use triethylene glycol to remove water vapor from 600 to 1200 psig natural gas streams. Wet...

... Abstract Triethylene glycol (TEG), diethylene glycol (DEG), and ethylene glycol (EG) are commonly used to dehydrate the natural gas stream. These compounds may be introduced into the sub-surface environment as a result of spills, leaks, mechanical failures, and past disposal practices...

... a great problem in the oil and gas industry. Among methods available for natural gas dehydration, absorption by means of triethylene glycol (TEG) has been used for many decades and remains the most popular. Nowadays very low natural gas dew points are required for gas transmission by pipelines...

... ABSTRACT The triethylene glycol (TEG) in the operated Bruce platform glycol dehydrator towers was seen to steadily increase to over pH 10. This rise in pH was found to be attributable to the carry over of triazine based H2S scavenger chemical, used to treat sour process gas. This paper details...

... Abstract Emissions of benzene, toluene, ethyl benzene, and the xylene isomers (BTEX) and volatile organic compounds (VOC) from the reboiler still vent of glycol dehydration units have become a major concern for the natural gas industry as a result of increasing regulatory pressure. The Clean...

... Abstract Increasing regulatory pressure has made emissions of benzene, toluene, ethylbenzene, and xylenes (collectively known as BTEX) and total volatile organic compounds (VOC) from glycol dehydration units a major concern for the natural gas industry since there are over 40,000...

... Corporation and the Gas Research Institute have developed a software program called GRI-DEHY© to provide gas producers with an easy-to-use tool for estimating emissions of BTEX and other VOCs from triethylene glycol dehydration units. This program uses fundamental chemical engineering thermodynamics along...

... The TEG Dehydration Unit comprises of two main plant sections; dehydration and regeneration. In the dehydration section, the wet gas is contacted with lean glycol to produce a dry gas meeting the standard specifications of 7 lb/MMSCF. The rich glycol stream passes through the regeneration section...

... glycol dehydration plants with lower emissions Process Group developed the GLYNOXX process, which offers glycol plant operators more favourable outcomes in terms of stripping gas usage and plant emissions compared to conventional stripping gas or aezotroping processes. In the GLYNOXX process stripping...

... and consequential safety issues. Monitoring the operation of glycol dehydration contactor towers through accurate and reliable on-line measurement of moisture in natural gas is therefore critical to efficient offshore natural gas production. This moisture measurement application presents a difficult challenge...

... ABSTRACT: Natural gas pipeline transportation requires very low water content in the gas stream in order to avoid condensation or hydrate formation. To reach this goal, when triethylene glycol (TEG) is used to dehydrate natural gas, after the absorption step TEG must be regenerated to levels...
