... In offshore gas field development, mono-ethylene glycol (MEG) has been a robust choice for hydrate inhibition in subsea production systems and flowlines. Once hydrate blockage forms, considerable efforts and loss of production are inevitable to remediate the hydrate blockage. Therefore...

... Abstract The chemistry of the Lean and Rich monoethylene glycol (MEG) closed loop circuits is dictated by decisions made by the flow assurance design team. During the life of the gas reservoir both short term events (e.g., completion fluids) and long term events (e.g., corrosion control, scale...

... Abstract The four Norwegian gas/condensate field developments Troll, Snøhvit, Ormen Lange and Åsgard are used together with amongst others Britannia Satellites (ConocoPhillips) and Shah Deniz (BP) to illustrate experience and technology status related to injection and recovery of MEG (Mono...

... life cycle period. Mono-Ethylene Glycol (MEG) is injected in wet natural gas trunk lines from an offshore gas field, as a means of hydrate inhibition during the winter season. The used MEG is supposed to be recovered in MEG Regeneration Unit (MRU) at onshore gas plant, where the wet natural gas...

... Abstract When monoethylene glycol (MEG) is used to provide hydrate protection for gas condensate production, MEG pre-treatment, reconcentration and reclamation systems are generally employed to recover and reuse the MEG. Prior to reconcentration, low solubility salts of divalent cations...

... A solution was to run two trains ; one train being dedicated to regenerate non-salt contaminated rich MEG from the topside JT trains, while the second train was dedicated to the salt contaminated system, regenerating MEG from subsea producing wells. However that was not a sustainable condition...

... Abstract Monoethylene glycol (MEG) regeneration systems often have a pre-treatment unit for controlled precipitation and subsequent removal of carbonates and hydroxides. The purpose is to avoid scaling in downstream process system. CaCO 3 is often the main solid removed in the pre-treatment...

... ABSTRACT Hydrate reformation could occur inside the production pipeline and is a crucial issue for methane hydrate production. In this work, the feasibility of inhibiting hydrate reformation with under-inhibition of MEG was investigated experimentally and economically. To understand...

... ABSTRACT A pipe viscometer was used to study the rheology of dispersions of various fluid systems. The first group of model fluid systems consisted of the light mineral oil Exxsol D60 and blends of water and glycerol. The second system consisted of real condensate and monoethylene glycol (MEG...

... ABSTRACT The influence of mono ethylene glycol (MEG) on the precipitation of calcium carbonate was investigated at constant supersaturation, 25°C, pH 8.5. Seeded and unseeded experiments were done in aqueous supersaturated calcium carbonate solutions containing MEG over the concentration...

... Abstract The paper reviews operational issues that arise when MEG is used for hydrate inhibition, especially when it is regenerated and recirculated. Thermodynamic equilibrium software can assess the scaling risk to some extent. Utilisation of data on nucleation and growth of scale formers like...

... The operational parameters were set as shown in Table 1 . A saturated solution (initial solution) with respect to calcite was added in the reactor, blanked with N 2 and heated up to 80 °C. A feed stream of rich MEG and a feed stream of alkalinity were pumped in the reactor by Metrohm 800 dosing...

Abstract Measurement and interpretation of corrosion inhibitor residuals in a mature offshore gas/condensate field could not be reconciled with field data leading to the identification of a potential infrastructure integrity threat...

... However, during the recoverability process, MEG may undergo multiple phases of thermal exposure. This will usually lead to the degradation of MEG which in-turn results in lower hydrate inhibition performance. Gas hydrates and prevention strategies have been researched extensively due...
