At a minimum, pressure vessels should be designed in accordance with the American Society of Mechanical Engineers (ASME) Code for material contents of varying characteristics. Facilities should address any added concerns about the temperature and characteristics of vessel contents (e.g., toxic, corrosive, reactive, or flammable contents). Read more

Many people do not know or are not realize that a Pneumatic pressure test can be very dangerous • Pneumatic testing is widely used to achieve minimum down time and economy and convenience of testing as compared to hydrostatic tests. It is also useful to detect very fine leak paths which may not be found in Hydrostatic testing. Read more

Distillation is a process in which a liquid or vapour mixture of two or more substances is separated into its component fractions of desired purity, by the application and removal of heat. This is a process used for centuries to separate compounds into their principal components. One such use comes to mind. Liquor stills to make “moonshine” were prevalent in the United States for many years. Read more

A Packed column utilizes packing to contact between the phases (liquid-vapor) on the surface. A major advantage to packed columns is the reduction in pressure across the column. Typically the column pressure drop for a packed column is less than that of a trayed column because of the percent open area. Read more

This article will discuss natural gas and how it is changed from the ground to your hot water heater or furnace. The process to do this is called Fractionation. It comes from the word fraction – which means a part of the whole. In fractionation, the natural gas will be broken into its components (or fractions). In order for this process to happen, many processes and many pieces of equipment are required. Read more
