Comparison of three methods for natural gas dehydration

Application of relative sensitivity function in parametric optimization of a tri-ethylene glycol dehydration plant

“…This is due to the fact that the presence of water molecules can form clathrate hydrates leading to pipeline plugging which is one of the most serious problems in the gas industry (Rahimpour et al, 2013a;Wen et al, 2012). The processes which are used for gas dehydration fall into five categories in principle: absorption with solvent, adsorption, gas permeation, refrigeration, and ultrasonic separation (Gandhidasan et al, 2001;Lin et al, 2013;Nemati Rouzbahani et al, 2014;Netusil and Ditl, 2011;Yang et al, 2014a;Yang et al, 2014b). Among these methods, absorption is the most commonly used process for natural gas dehydration and is the most attractive one from an economic point of view (Isa et al, 2013;Woodcock and Gottlieb, 2000).…”

The Impact of Stripping Gas Flow Rate on Triethylene Glycol Losses from Glycol Regeneration Unit: Simulation Study

“…In direct cooling or (condensation), natural gas can be efficiently cooled using the Joule-Thompson effect [2]. Compression of the hot gases saturated with water at the lowest temperature value will resulted in prevention further condensation of water.…”

“…The industrial dehydration process is carried out using several methods including direct cooling (condensation), adsorption and absorption [2]. Recently, membrane dehydrators are used.…”

Földgázipari káros emisszió mérésére, optimalizálására alkalmas műszerek fejlesztése

“…A földgáz szárítására többféle módszer létezik [69,70], a leggyakoribbak az abszorpció és az adszorpció [71], de megemlíthető még a membrános eljárás [72,73] is. Abszorpció esetén folyékony szárítószert alkalmaznak, amely az esetek döntő többségében trietilén-glikol, ritkábban di-, esetleg tetraetilén-glikol (rövidítéseik rendre TEG, DEG, TREG).…”
