Abstract :
- Hydrate formation presents a significant
operational challenge in offshore oil and gas production,
primarily due to the potential formation of hydrate plugs
which obstruct fluid flow, thereby posing serious flow
assurance risks. Additionally, these solid, crystalline, icelike structures, composed of low molecular weight gases
(such as methane, ethane, and propane) encapsulated in
hydrogen-bonded water cages, can aggregate into larger
masses capable of damaging or rupturing pipelines. Such
formations typically occur under the high-pressure and
low-temperature conditions prevalent in subsea flowlines
and cold-weather operations. This study employs the
Prosper simulation software to model these complex
thermodynamic and hydrodynamic conditions and to
predict the effective dosages of chemical inhibitors
required to prevent hydrate formation. Specifically, our
simulations suggest optimal dosages of 35% wt.
methanol (MeOH) and 45% wt. monoethylene glycol
(MEG) for gas stream 1, and 22% wt. MeOH and 33%
wt. MEG for gas stream 2. Based on these findings, we
advocate the use of Prosper simulation software as a
predictive tool for the strategic administration of
hydrate inhibitors in offshore gas production facilities.
This research contributes to the ongoing development of
chemical strategies for hydrate management, providing a
basis for improved safety and efficiency in hydrocarbon
extraction processes.
