Скачать или смотреть V.18 Methanol Optimization: Saving Money & Protecting Pipelines

This video discusses TPA’s approach to optimizing methanol injection for hydrate control in pipelines.

TPA recognizes the significant operating expenses associated with methanol injection and the lack of strict controls in determining the need for methanol and optimizing injection rates.

TPA’s focus on methanol optimization began in 1994 when the industry recognized the role of excessive methanol injection in top-of-the-line corrosion failures.

The video explains the mechanisms behind methanol-induced corrosion, which involves the condensation of methanol droplets in specific pipeline sections, leading to accelerated corrosion rates.

TPA highlights its understanding of hydrate formation and its consideration of both thermodynamic and kinetic factors.

TPA’s approach involves using pipeline hydraulic models, hydrate formation temperature calculations, and water film transport analysis to determine the optimal methanol injection rates.

The video provides an overview of TPA’s hydrate and methanol optimization calculator, which provides detailed assessments and recommendations for methanol injection strategies.

TPA emphasizes the importance of considering factors like pigging frequency, operating conditions, and potential biases in hydrate formation temperature and cold gas temperatures to achieve accurate methanol injection optimization. https://trustedpipelineadvisor.com
