Drum and Tower

Column Towers are abbreviated as VT- Vessel Towers on their metal plate tags.

Drum Towers are abbreviated as VD- Vessel Drums. (Valve Relief Line-VRL)

Towers and Drums are also called the Pots And Pans of the plant.

Lagging is a form of insulation- Lagging is used prevent injuries. (please google all the uses of Lagging)

Vessels/ Columns have Trims, trims consist of anything attached to the tower, trims are as follows; Ladders, Compressors, Pressure Safety Valves (PSV), Reflux Drums, Level Glass (these reading are also found on kettles, used for measurements), Re-boilers (eg. Furnace Re-boilers and Steam Re-boilers), Heat exchangers, Thermo-wells (these are devices put into the column looks like an oil stick), Pressure Instruments and vents

The tagging of the devices are in the form of metal plates, these metal plates give information about the vessel example the Maximum and Minimum Pressures that the device can withstand, etc.

For Support the Column Tower stands on a fire proofing underground shield, this is there to prevent the tower from collapsing during fires.

An adsorber is a fixed bed of special material example Activated Charcoal. The Activated Charcoal absorps unwanted components from liquids.

What is a reactor?

A Fixed bed reactor is a reactor which has a fixed bed of catalyst. Here are two examples of an Alkylation Reactor- It uses HF (Hydrofluoric Acid) which reaches the feed and the recycle stream and in a Alkylation Tower is cooled down using water.

QUESTION THAT NEED TO BE ANSWERED STILL

WHAT IS A QUENCH TOWER? The Quench tower is designed and engineered for cooling high temperature exhaust gases from incinerator, melting furnace, drying furnace, etc. Exhaust gas from high temperature sources is cooled down with water vapor to the saturation temperature of the gas by Quench tower. Quench Towers can either be cooled by a water or oil medium, this regulates whether it is called a Quench Water Tower (QWT) or Quench Oil Tower (QOT).

WHAT IS A DRIER?

WHAT IS A TREATOR?

WHAT IS A DECANTOR?

It is a continuous gravity separation vessels via the difference in density.

WHAT IS A ACCUMULATOR?

What's An Accumulator?A hydraulic accumulator is a device in which potential energy is stored in the form of a compressed gas or spring, or by a raised weight to be used to exert a force against a relatively incompressible fluid.

They are used in fluid power systems to accumulate energy and to smooth out pulsations. A hydraulic system utilizing an accumulator can use a smaller fluid pump since the accumulator stores energy from the pump during low demand periods. This energy is available for instantaneous use, released upon demand at a rate many times greater than could be supplied by the pump alone.

Accumulators can also act as surge or pulsation absorbers, much as an air dome is used on pulsating piston or rotary pumps. They will cushion hydraulic hammer, reducing shocks caused by rapid operation or sudden starting and stopping of power cylinders in a hydraulic circuit.

There are four principal types of accumulators, the weight loaded piston type, diaphragm (or bladder) type, spring type and the hydropneumatic piston type. The weight loaded type was the first used but is much larger and heavier for its capacity than modern piston and bladder types. Both the weighted type, and mechanical spring type are very seldom used today. The hydro-pneumatic types use a gas as a spring cushion in conjunction with a hydraulic fluid, the gas and fluid being separated by a thin diaphragm or a piston. Tobul accumulators, having an aluminum piston of low inertia as standard equipment, are superior to other makes in absorbing either high or low frequency pulsations.

 

WHAT IS A K.O POT?

A vapor–liquid separator is a device used in several industrial applications to separate a vapor–

liquid mixture.

A vapor–liquid separator may also be referred to as a flash drum, knock-out drum, knock-out

pot, compressor suction drum or compressor inlet drum. When used to remove suspended water

droplets from streams of air, it is often called a demister.

Method of operation[edit]

For the common variety, gravity is utilized in a vertical vessel to cause the liquid to settle to the

bottom of the vessel, where it is withdrawn.[1][2][3][4]

In low gravity environments such as a space station, a common liquid separator will not function

because gravity is not usable as a separation mechanism. In this case, centrifugal forceneeds to be

utilized in a spinning centrifugal separator to drive liquid towards the outer edge of the chamber for

removal. Gaseous components migrate towards the center.

For both varieties of separator, the gas outlet may itself be surrounding by a spinning mesh screen

or grating, so that any liquid that does approach the outlet strikes the grating, is accelerated, and

thrown away from the outlet.

The vapor travels through the gas outlet at a design velocity which minimizes the entrainment of any

liquid droplets in the vapor as it exits the vessel.

The feed to a vapor–liquid separator may also be a liquid that is being partially or totally flashed into

a vapor and liquid as it enters the separator

WHAT IS A BLOWDOWN DRUM?

In a refinery, each piece of equipment or vessel is tied in to a relief system. So if one piece of equipment were to fail or was overpressured and needed to relieve pressure, it would do so through the relief valves into a relief header, and ultimately into a blow-down drum. The chemicals and gases cannot be released to the atmosphere so they are released to a drum.

WHAT IS A STORAGE DRUM?

It is the drum where desired products are stored.

WHAT IS A SPHERE?

It is a High volume and high pressure storage tank.

WHAT IS A BULLET?

It is a low volume and low pressure storage tank.
