Liquid Drop Sizes in Gas-Liquid Systems

The gravity settling theory above provides valuable insight into the significance of certain physical properties and the physics that together influence the separation of dispersed droplets from a continuous phase, e.g. liquid droplets from a gas or liquid droplets of a specific density from a liquid phase of another density. However, a couple of problems […]

Hortonsphere Vessel

The Hortonsphere vessel permits the storage of a large volume in one unit with only one set of pipe connections and fittings. Batteries of shop built-up cylindrical tanks have been used to provide large volumes of pressure storage. This practice necessitates the use of multiple pipe connections and the duplication of tank fittings, vents and […]

Vapor Recovery Systems

Vapor recovery systems are generally used to prevent pollution of the environment and to recover valuable product. Two basic types of vapor recovery systems may be encountered. One is designed to gather toxic wastes that would pollute the atmosphere but are not valuable enough to warrant full recovery. In this type system, the vapors are […]

Storage Vapor Losses

Vapors emitted from the vents and/or relief valves of a storage tank are generated in two ways: • Vapors that are forced out of the tank during filling operations. • Vapors that are generated by vaporization of the liquid stored in the tank. A vapor recovery system should be sized to handle the total vapor […]

Refrigerated Tank Insulation Systems

Low temperature insulation is required for both spherical and flat bottomed cylindrical refrigerated tanks. Two types of insulation systems are commonly used for low temperature service — single wall and double wall. In the single wall system, the vessel wall is designed to withstand the design service conditions of the liquid to be stored. The […]
