# Fire Point :-  The lowest temperature at which the vapor of that fuel will continue to burn for at least 5 seconds after ignition by an open flame. #Smoke Point:-   The temperature at which, under specific and defined conditions, an oil begins to produce a continuous bluish smoke that becomes clearly visible. #Freezing Point:-  The temperature at which water changes phase from a liquid to a solid. # Dew Point:-   T he temperature at which air is saturated with water vapor. # Flash Point:-  T he lowest temperature at which enough fluid can  evaporate to form a combustible concentration of gas. #Pour Point:- The lowest temperature at which the oil will pour or flow when it is cooled without stirring. #Boiling Point:-   The temperature at which the vapor pressure of a liquid is equal to the pressure of the atmosphere on the liquid. #Bubble Point:-   The temperature wh...

#Critical Point:-   A point on a phase the diagram at which both the liquid and gas phases of a substance have the same density, and are therefore indistinguishable. # Surge point:-   ( For Rotating Equipments) , the peak point at the Performance Curve of the Centrifugal Compressors where the flow reversed back through compressors blades.  # Yield point:-   In mechanical engineering, the load at which a solid material that is being stretched begins to flow, or change shape permanently. # Aniline point:-  The lowest temperature at which aniline and a solvent (as gasoline) are completely miscible and which serves as an indication of the type of hydrocarbons present in the solvent, the content of aromatics being higher according to as the temperature is lower. # Triple Point:-   The temperature and pressure at which the three phases (gas, liquid, and solid) of that substance coexist in thermodynamic equilibri...

#Control valve has 3 basic Components: 01. Actuator Most actuators are pneumatic. Usually, an actuator works with the help of a diaphragm and instrument air. This is the device that positions the throttling element (i.e., the valve plug inside the valve body). 02. Valve body subassembly This is the part where the valve plug, valve seats, and valve casing are located. 03. Accessories These include positioners, I/P (current- to-pressure) transducers, and position sensors.  #2 types of control valves are based on their motion:- 01. Linear-Motion valves as- A- Gate Valves.                                                  B- Diaphragm Valves.                                                  C- Globe Valves. 02. Rot...

Let's know about what is  bearing , which knowledge can make it easy to operate at chemical, petrochemicals or any other processing plant. A bearing is a mechanical element which allows motion between two rotating parts, with minimum friction. An example of such rotating parts is a shaft and its housing.  The function of bearing A good bearing is expected to do the following functions.  =It should ensure free rotation with minimum friction.  =It should support rotating parts and maintain them in the correct position. =Bearing should transmit the forces acting on rotating parts to the frame of the machine. Different types of bearing: *Deep Groove ball bearing. Deep Groove ball bearing Deep Groove ball bearing *Angular contact ball bearing. Angular contact ball bearing *Self-aligning ball bearing. *Cylindrical roller bearing. *Tapper roller bearing. *Spherical roller bearing. *Cylindrical plain bearing. *Split type plain ...

Let's know about what is Process, Process Symbol, Process Diagram, which can make it easy to operate at chemical, petrochemicals or any other processing plant. #what means process? =When an output product is found through a single or multi-stage material or mixer's physical or chemical change, it is called a process. #What is Process Symbol? =Process symbol Maybe defined as the graphical alphabetical or mathematical representation of the different types of pipeline, valves or fittings, equipment, instrument, etc of the Process Industries. #what is process diagram? =All the instrumentation or fittings or parts of a process can be expressed through a diagram, that's called a process diagram. Different types of process diagram: 01.Block diagram. A block the diagram is a diagram that's the easiest way to represent a process. Features of the block diagram: =A single piece of equipment is meant for a block. = Blocks should be of equal size...
