Visbreaking
Visbreaking is a common process in oil refineries that helps make thick, heavy oil products more fluid and usable. Think of it like making honey thinner and easier to pour by heating it up. This process is important because it allows refineries to produce more valuable products like gasoline and diesel fuel from heavier oils. The term "Visbreaking" comes from "viscosity breaking" - viscosity being how thick or flowing a liquid is. When you see this term on a resume, it usually indicates experience with refinery operations, particularly in processing heavy oils.

Example Interview Questions
Senior Level Questions
Q: How would you handle a situation where the visbreaking unit is showing decreased efficiency?
Expected Answer: A senior operator should discuss monitoring key parameters like temperature and pressure, checking for coking or fouling issues, and implementing preventive maintenance schedules. They should also mention team coordination and safety protocols.
Q: What improvements have you implemented in visbreaking operations?
Expected Answer: Should discuss experience with optimization projects, such as reducing energy consumption, improving product quality, or implementing better safety procedures. Should mention specific examples and results.
Mid Level Questions
Q: What are the main safety considerations in visbreaking operations?
Expected Answer: Should explain basic safety protocols, including temperature monitoring, pressure control, and emergency shutdown procedures in simple terms. Should demonstrate awareness of common hazards.
Q: How do you monitor visbreaking product quality?
Expected Answer: Should describe basic quality control measures, sampling procedures, and key properties to monitor. Should understand how product quality affects downstream processes.
Junior Level Questions
Q: What is the purpose of visbreaking?
Expected Answer: Should be able to explain in simple terms that visbreaking makes heavy oils lighter and more valuable by heating them up, and understand the basic process flow.
Q: What are the main parameters to monitor in visbreaking?
Expected Answer: Should know basic operating parameters like temperature, pressure, and flow rates, and understand why they are important to monitor.
