... Abstract The pH stabilization technique is a method for control of sweet corrosion in wet gas pipelines. The method is suited for systems with MEG for hydrate control as the pH stabilizer will remain in the lean MEG and do not need a continuous injection. Full pH stabilization is used when...

..., Monoethylene glycol (MEG) is often used. The continuous use of pH stabilizers in natural gas pipelines can lead to the formation of desirable and undesirable scale formation. If the use of pH stabilizers gives negative effects due to the formation of unwanted scale, the increase in the pH of the system...

... levels of H 2 S and, possibly, elemental sulfur. The main three parameters of interest are the effect of elemental sulfur, sulfur solvent, monoethylene glycol (MEG) and possible mutual interactions between them. The experimental work is carried out in a 20L N10276 autoclave under 4 bars of H2S and 10...

... transport pipelines to avoid hydrate formation. Mono Ethylene Glycol (MEG) is commonly used for this purpose; typically about 80 wt.% MEG is injected at the well head and the aqueous phase at the end of the pipeline contains about 40 wt.% MEG. The effect of MEG on internal condensation in pipelines has been...

... ABSTRACT Monoethylene glycol (MEG) is injected in the pipelines to prevent hydrate formation, and subsequent pipeline blockage. Recent investigations indicated that presence of MEG could impede CO 2 corrosion of carbon steel, although many aspects remain unknown. In the current study...

... ABSTRACT When the gas contains ethylene glycol ( MEG ) and organic acids these components will also dissolve in the water condensing on the pipe wall and affect the potential corrosion rate and the protective properties of the corrosion product film that forms on the pipe wall. The film...

... ABSTRACT A study to investigate the influence of monoethylene glycol (MEG) on inhibition of corrosion in acid CO 2 saturated conditions in wet gas pipelines (carbon steel) was performed. MEG is a thermodynamic hydrate inhibitor. The quest for energy encourages more offshore gas development...

Some tests have also been done at 80 and 40°C, and the test solution has been modified accordingly. The effect of back production of formate completion fluid has also been...

... ABSTRACT The Ormen Lange production facilities consist of subsea production units with multiphase pipelines carrying gas and condensate to an onshore processing plant. At the onshore plant there are four storage tanks for intermediate storage of MEG/water fluids, which are regenerated...

... ABSTRACT This paper compares the suitability of 22 Cr duplex stainless steel (UNS S31803), low alloy steel, and Alloy 625 (UNS N06625) for MEG reclamation systems. Oxygen is of particular interest. Corrosion of duplex stainless steel in the presence of high oxygen concentrations under MEG...

... INTRODUCTION ABSTRACT Ormen Lange gas /condensate field is developed with a subsea to shore concept at sea depth of approximately 1000 meters. Unprocessed gas, condensate and MEG (Mono Ethylene Glycol)/water will be transported through two 120 km carbon steel pipelines. Formation of hydrates...

The method is only applicable for systems where no aquifer water breakthrough is occurring due to risk for calcium carbonate scaling...
