Emulsion challenges in Malaysia crude oil processing post several key risk into Malaysian Refinery that leads to key separation equipment operational trips and leading to Unplanned Loss Profit Opportunity (ULPO) for the refinery plant. Detail analysis and fingerprinting of emulsion in crude has been conducted to identify the potential root causes that covers the total value chain of this crude from drilling platform (upstream) all the way to the end users (downstream).

The emulsion sourced and its genetics was traced, sampling method were scrutinised, design limits were questioned, and historical data were analysed throughout the process. The methodology taken has lead to the identification of the potential root causes that either causes emulsion to happens and stabilized throughout the supply chain. This technical talk will detail out the basic principles of emulsion, factors that create or stabilized the emulsion and basic understanding in managing the emulsion.
