Industrial Static Vessels And Towers.
Static vessels and towers are significant pieces of equipment in any type of processing plant. There is no place such as in Ammonia Processes, Basic Processes, Chemical Engineering, Chemical Process Technology, Chemical Industries, Lubricant Manufacturing, Manufacturing Industries, Oil and Gas, and Petrochemicals, where not need Static Vessels And Towers.
In a chemical plant any piece of equipment that contains a Liquid, Gas, or Solid, may be called a "Vessel". A Vessel can be any size or shape. The position of the vessels may be horizontal or vertical.
There are some examples of Static Vessels and Towers that are commonly used in various petrochemical and chemical plants.
Packed Tower, Bubble Tower, Column, Ion Exchange Tower, Chamber, Tank, Digester, Reactor, Pan, Drum, Heat Exchanger, Stripper, Converter, Cooler, Absorber, Desorber, Deaerator, Dehumidifier, Chiller, Re-boilers, Boilers, Air Cooler, Heater, etc.
Here is a description of some of the Static Vessels And Towers in the above examples.
Packed Tower:
Columns and Towers are sometimes filled with an inert material referred to as "Packing". When a tower has been filled with "Packing", It is called a Packed Tower.
Bubble Tower:
Columns and towers are sometimes equipped with Bubble Cap Tray or Ballast Trays as "distributors" to bring liquid and vapor into close contact are called Bubble Tower.
Extraction Column:
Vertical process vessel in which desert product is separated from a liquid by counter-current contact with a solvent in which the desired product is preferentially soluble.
Ion Exchange Tower:
Ion Exchange Tower is an ion-exchange column where dissolved mineral salts in water are removed by exchanging ions with the aid of ion exchange (resin).
Absorber:
The absorber is equipment in which a gas is absorbed by contact with a Liquid. An absorber may contain one or more Packed Towers and Bubble Towers. A solid or liquid that absorbs another substance is called an Adsorbent.
Desorber:
December is equipment in which the process of removing an absorbed gas as absorbed by a liquid or liquid is performed. A Desorber also may be arranged with one or more Packed Towers and Bubble Towers.
Reboiler:
An auxiliary heating unit for a fractionation tower is designed to supply additional heat to the lower portion of a tower. Liquid withdrawn from the side or bottom of the tower is preheated by heat exchange, then introduced into the tower. It also works like a Heat Exchanger.
Deaerator:
The Deaerator (DA) tank uses steam to preheat boiler feedwater to a temp. at which dissolved O2 & CO2 will become separated from the feedwater before it is pumped to the boiler. The purpose is to protect the boiler and steam/condensate piping from corrosion that would be present when the water evaporates into steam. An additional benefit is that the number of chemicals used to treat the boiler water can be reduced.
Reactor:
A reactor is a static device or a process vessel, in which a chemical reaction takes place during a chemical conversion type of process. A reactor vessel catalyst or non-catalyst can be of two types, i.e. reaction can occur in the presence and absence of a catalyst.
Pressure Vessels Codes:
Governing authorities established or adopts Safety Codes And Standard Rules for boiler and pressure vessels.
Governing Authorities:
Governing authorities are:
ISO - International Organization for Standardization,
ASME - The American Society of Mechanical Engineers,
JIS - Japanese Industrial Standards,
DIN,
Inspection Of Vessels:
Welding Joints,
Corrosion / Erosion,
Wall Thickness,
Method Of Inspection:
Visual Inspection,
Inspection By Nondestructive testing (NDT).
