Abstract:
PHMSA’s Oct 5, 2022 rule mandates rapid leak notification (15 min) and response (30 min) for “Type A” gathering pipelines with diameters ≥6 inches. This paper explores compliance challenges, infrastructure issues, proposing a pressure-based leak detection system using unsupervised machine learning for timely alerts, backed by experimental data and continuous learning for enhanced reliability.

Abstract:
A clear understanding of the flow characteristics of CO2 pipelines under various operating conditions, including leaks, provides valuable insights for effective monitoring and design of reliable leak detection systems. In this paper we discuss a novel mathematical model of a CO2 pipeline and conduct simulations to replicate the complex phenomenon of CO2 release. The approach and findings of this paper contribute to enhancing leak detection in pipelines, thus mitigating emissions of greenhouse gases.
