An air release valve is a mechanical device used in piping systems to automatically release trapped air. It is commonly found in water pipelines, wastewater systems, and pressurized tanks. Here’s a brief overview: Purpose: Removes air pockets that can form at high points in a pipeline. Prevents flow restrictions, pressure surges, and potential damage caused by air accumulation. Improves system efficiency and protects equipment. Types: 1. Air Release Valve – Discharges small amounts of air under

Valves in a Distillation Column: Functions and Location In a distillation column, different types f valves are used to ensure safe, efficient, and controlled operation. Each valve has a specific role depending on its location in the process. 1. Gate Valve Location: Feed line and main roduct lines (toP and bottom). Function: Used for complete shut-off or full floW (on/off. • Benefit: Simple design and effective for isolating large flow streams. 2. Globe Valve • Location: Reflux line (between cond
