Question With Answer About Turbine And Compressor In Process Industries.

 


The turbine is a mechanical device or mechanical mechanism that converts thermal energy to mechanical/kinetic energy. In Petrochemicals, Chemicals, Power Generation, Ammonia, Oil and Gas, Manufacturing Industries, the steam turbine is used as the driving system or driver. Such as a steam turbine used to drive a  power generator in the power plant.

A compressor is a mechanical device through which increased the pressure and density of a gas or vapor. Many types of compressors are used in the field especially in the industry, Such as; Compressor Rotary, Compressor, Compression System, Air Compressor, AC Compressor, Air Dryer Compressor, Refrigeration Compressor, etc.

 

Already on my site Tech Process, there are already two topics related to What Is Compressor And Compression System? Working Principle Of Compressor. and The Steam Turbine, And How It Works?  is discussed about compressors and turbines.

 

Let us today discuss some of the issues related to compressors and turbines that I have shared with you some of the knowledge I have gained from working on compressors and turbines that I have seen in real life.

 

An important part of A Turbines and Compressors is the Turning Gear which plays a very important role in turning the turbines and compresses shaft or rotating parts during startup and shutdown.

 

# Now let's see why turning gear is used in a turbine and a compressor?

Turning gear is used in a turbine for rotating the shaft at the time of warm-up of the turbine or when its rotor comes to standstill after any trip for the protection of the shaft from deformation due to un-uniform temperature in its surface at that moment when the rotor is at hot. Another thing to note here is that before turning on the Turning gear, you must make sure that the lube oil circulation of the turbine is turned on. If the rotor or shaft is not rotated evenly during the warm-up or cooldown of the turbine, the turbine rotor or shaft will bend.

 

# Now let's know why do you warm up the turbine before starting?

We warm up the turbine before starting for avoiding the thermal shock experienced by the cooling device at the time when a larger volume of steam carrying high temperature gets entranced suddenly in its causing crack.

 

# Now we will see how many types of bearings are used in compressors and turbines? What is the function?

There are three types of bearing used in a turbine.

  • Axial Bearing,

  • Radial Bearing,

  • Thrust Bearing.

At first, let's know what's the meaning of Axial Thrust. When the thrust is experienced by a turbine of the compressor, acting along the axis is called axial thrust.

The function of thrust bearing is to fix the position of the turbine or compressor rotor in the axial direction and take up the unbalanced axial thrust (Residual Thrust) of the balance piston (Drum).

 

#What is the function of Journal Bearing?

The function of Journal bearing is to support the shaft or Rotor. It consists of a lower and upper half shell. The shells are lapped with white metal and located by means of pins.

If there is insufficient lube oil flow in the bearing or generates excessive friction, the white metal of the journal bearing protects the rotor or shaft.

When a turbine or compressor rotates on the oil bed or oil film between the bearings and rotor, the journal bearing holds the rotor or shaft in the correct position. So that the rotor or shaft is not unbalanced.

 

# What is the function of Steam Admission Valve and Emergency Stop Valve (ESV) in a turbine?

The function of the steam admission or regulating valve is to regulate the steam of the turbine as per its desired speed. Emergency Stop Valve (ESV) is used before Steam Admission Valve in a turbine to save the Machine by cutting steam completely at the time of its abnormal condition. When the turbine is made shut by pushing the Emergency Stop Button or when the machine is tripped for other causes according to their predetermined set point. Emergency Stop Valve (ESV) is closed quickly and completely by damping the control oil.

General Checklist List for Pre-start and Starting up the Centrifugal Pumps.

General Checklist the Essential Steps and precautions for Pre-start and Starting up the Centrifugal Pumps . # What’s the things you Should be attention physically? # General centrifugal pump start up procedure:- Before pump start-up you must perform these tasks:- *01.  Open the suction valve , do priming by venting all the air inside the suction line by opening any vent or even the PG vent till liquid coming out then close , now you confirm no air inside the system to reduce the chances of pump getting cavitation *02.   Open any re-circulation  or cooling lines. *03.   Fully close or partially open the discharge valve, depending on system conditions. *04.   Start the driver. *05.   Slowly open the discharge valve until the pump reaches the desired flow. *06.   Check the pressure gauge to ensure that the pump quickly reaches the correct discharge pressure. *07.   If the pump fail to reach the correct pre...

Industrial Catalyst And Classification.

Principle Of Industrial Catalyst And Classification Of Catalyst.   Principle Of Industrial Catalyst : An industrial catalyst is a substance that accelerates a chemical reaction without undergoing any significant change in its own chemical composition. Catalysts work by lowering the activation energy required for the reaction to occur, thereby increasing the reaction rate. They provide an alternative pathway for the reaction to take place, which requires less energy and allows the reaction to proceed at milder conditions such as lower temperatures and pressures. Industrial catalysts are used in a wide range of chemical processes, including petrochemicals, refining, polymerization, and environmental applications. Classification Of Industrial Catalyst : Industrial catalysts can be classified into four main groups: 01. Homogeneous catalysts. Homogeneous catalysts are soluble in the reaction medium and are used mainly in the production of fine chemicals and pharmaceuticals. 02. Heteroge...

Difference between LNG, LPG and NGL

✅ LNG — Liquefied Natural Gas, is gas that has been Liquified at very low temp. and is transported as a liquid. It’s Primarily methane ,NG is a mixture of HC which, when liquefied, form a clear colorless,odorless liquid; it’s usually transported and stored at a temp. very close to its boiling point at atmospheric pressure (~ -160), The actual composition of LNG will vary depending on its source and on the liquefaction process, but in all cases the major is methane with small percentages of the heavier HC such as ethane, propane, butane and pentane ,N2 may be present.  ✅ LPG — Liquefied Petroleum Gas gas that is liquid near room temperature and at some extent of pressure. This product has very little methane and butane and is primarily propane (C3),LPG is more dense (has a higher specific gravity) than natural gas ,Their common characteristic is that they can be compressed into liquid at relatively low pressures ,The two most common LPG constitutes are Propane and Butan...
