Chemical Equipment and Maintenance Operation.
Chemical Equipment is used in pharmaceutical, chemical, Food and beverage and Agric industries for chemical reaction.
There are various type of equipment which is use in chemical industry.
- Reactor /Kettle
- Filter Press
- dryer
- Pulverization
- Blender
- Pipe and Fabrication
- Pumps
Reactor /Kettle
A various types of chemical reaction and process takes place in enclosed vessel. In chemical engineering A chemical reactor is a process equipment where in chemicals are fed in order to make them chemically react.
Material of vessel /Reactor (MOC)
- SS
- MS
- MSGL (Glass Line Reactor)
- HDPE
- FRSVE

Accessories on Kettle/Reactor
- Motor
- Gear Box
- Lantle assembly
- Mechanical seal/Gland filling
- Thermo well
- Level transmitter
- Agitator
- Baffles

- Dip pipe or Diverter
Function of Reactor Component
Body of Kettle
Motor
- It is use for driving Agitator in Kettle as it converts electrical energy to mechanical.
- Mainly Motor of All kettle is Having 1440 RPM, but some time as per requirement we use 2900 RPM motor
- Depend on Zone of classification we use FLP or Non FLP motor.
- Some motor shaft has gear mounted and some having pulley.
Gear Box
- Mainly use for reducing speed of agitator from speed of motor.
- Gear ratio is depend on application and process requirement.
- Do greasing to bearings in bearing housing.
- Check bearing housing bolt condition and its tightness.
- Check condition of coupling bolts and its tightness.
- Check for any oil leakage Top up oil if level got lowered.
- Check foundation bolts Check belt condition is applicable
Lantle Assembly
It is mainly for holding shaft at
center of the kettle and give bearing in it for shaft in bearing housing in it.
1. Do greasing
to bearings in bearing housing.
2. Check
bearing housing bolt condition and its tightness.
3. Check
condition of coupling bolts and its tightness.
Mechanical seal
It uses for avoiding fumes from
reactor inside to come out from reactor.
It also helps for keeping
shaft concentric and avoid run out of shaft.
Types of agitator seal
Single dry mechanical sealDouble mechanical seal

Thermo well
- It is for measuring temperature of chemical inside the kettle
- cylindrical fittings used to protect temperature sensors installed in industrial processes
- Typically, a thermowell is made from metal bar stock
- A thermowell acts as a barrier between a process medium and the sensing element of a temperature measuring device.
- Silicon oil is use for enhancing heat transfer from process fluid to RTD rod

Level transmitter
- This
instrument is for level indication inside kettle
- It may
be mass or radar type

Agitator
An agitator is a mechanical
device that helps in shaking or stirring a liquid or mixture of liquids.
Agitators are widely used for multiple operations in the chemical,
pharmaceutical, food, grease, metal extraction, paint, adhesive, water, and
cosmetic industries.
Application and uses of Agitator
- To get proper mixing of liquids.
- To promote chemical reaction inside the equipment.
- To increase heat transfer during heating or cooling
- To keep homogeneous liquid bulk during storage.
- To disperse immiscible liquids.
- To keep the product in a mixed state till used.
Different Types of Agitator
- Turbine Agitators.
- Paddle Agitators.
- Anchor Agitators.
- Propeller Agitators.
- Helical Agitators.
