Several Studies Proceed For the HTPS: Challenges and Optimization
Article Sidebar
Main Article Content
Abstract
The rapid expansion of oil production has increased the demand for effective separation systems, with oil separators playing a vital role as the first stage in oil production due to their fast response. The horizontal three-phase separator (HTPS) is the most commonly used type, valued for its effectiveness and low maintenance requirements. HTPS is an essential component in oil and gas production systems, efficiently separating crude oil into oil, water, and gas phases. This paper examines the limitations of current research and the challenges associated with a comprehensive review of HTPS components and optimization methods. It outlines the design fundamentals, internal configurations, and operational challenges, while also analysing mitigation techniques. This study provides a comparison between different optimization approaches in the oil recovery (OR) separator. This study contributes to ongoing research and serves as a practical guide for enhancing the design, efficiency, and reliability of TPSHs in diverse operational environments.
