water,LSW water,portable water.
2)cooling tower
3)nitrogen
4)fuel gas & fuel oil
5)caustics
6)Air(plant air,instrument air)
7)Energy(power plant)
8)fire water,service weter.

Answer / markand joshi

utilities means without which plant can not run say

air with out that instument air is not there so valve can
not be operaed
then steam then cooling water and then nitrogen then
electricity are the basic requirement.

Answer / vinod kumar jtav

The utilities of a process plant include the following.
1. purified water
2. water for injection
3. Boiler (Steam generator)
4. clean system
5. nitrogen and other medical gases plant
6. Compressed gas system
7. heating, Ventilation and Air conditioning systems
8. Air dryers, etc.,

The utilities very essential for proper validation of a
process plant,
without which production and validation not accept.

Answer / m.bhoopala krishnan

The utilities of a process plant include the following.
1. DG sets
2. Compressors
3. Boiler (Steam generator)
4. Hot oil units
5. Cooling towers
6. D.M. Plant
7. N2 Plant
8. Air dryers, etc.,

The utilities are said to be the heart of a process plant,
without which production comes to hault.

Answer / aftab nisar farooqi uog bs te

The requirements on the base of which a plant or industry can work are called plant utilities without these thing a plant cant work properly or can not start .
Such as :-
Steam
Chilled water
Hot water
Compressed air 3 or 4 bar
N2 gass
Fuel
Electricity
Raw water and etc

Answer / umesh kumar

Utilities are parts of production of product /products which is not directly involved in raw materials or in product,only it used for maintaining desired process conditions and maintain the economics of plants
Exp-compessed air
Water
Steam, nitrogen etc

Answer / ashish gautam

It signifies about the raw materials which we are using in a chemical plant it may be anything which may leads to direct production and fulfillment of any need which may lead to start up of the plant.

Answer / nandhu

utilities include distillation column, evaporator, vacuum
separater, etc.....

Question 78 - Fact 1 : Dry air contains 20.95 % oxygen, 78.09 % nitrogen, 0.93 % argon, 0.039% carbon dioxide, and small amounts of other gases by volume. Fact 2 : Volume occupied is directly proportional to the number of moles for ideal gases at constant temperature and pressure. Fact 3 : 12.5 moles of pure oxygen is required to completely burn 1 mole of pure octane. Fact 4 : Air–fuel ratio (AFR) is the mass ratio of dry air to fuel present in a combustion process such as in an internal combustion engine or industrial furnace. Fact 5 : Molecular weight of oxygen gas is 31.998 g / mole and molecular weight of nitrogen gas is 28.014 g / mole. (a) Find the molar ratio of nitrogen and oxygen, or (moles of nitrogen) / (moles of oxygen) in dry air, by assuming ideal features of nitrogen and oxygen gases. (b) How many moles of nitrogen are available if dry air is used to completely burn the 1 mole pure octane? (c) Find the mass of fuel of 1 mole of octane with molecular weight of 114.232 g / mole. (d) Find the mass of dry air with 12.5 moles of pure oxygen by assuming only oxygen and nitrogen gases exist in the air. (e) Find the air-fuel ratio (AFR) when octane is used as fuel. (f) Find the fuel-air ratio (FAR) when octane is used as fuel.

Question 39 - Acetone and ethanol are separated using a distillation column with a partial condenser and partial reboiler. An equimolar, sub-cooled liquid feed enters at 100 kmol / hr and condenses 1 mole of vapor for every 6 moles of feed. The separation requires a distillate vapor that is 95 mol % acetone and bottoms liquid that is 5 mol % acetone. The reflux is returned from the condenser to the column as a saturated liquid and the operation is run at (L / V) = 1.4 * (L / V) min. Assume constant overflow conditions. (a) Feed operating line is y = [ q / (q - 1) ] x - z / (q - 1) where z = 0.5 for equimolar liquid mixture of 2 components, q = (L’ - L) / F where L’ = L + F + (F / 6) for condensation of 1 mole of vapor / 6 moles of feed. What is y = f(x)? (b) The rectifying operating line is y = (L / V) x + (D / V) (xd) where (L / V) min goes through the points A (0.95, 0.95) and B (0.53, 0.69), V = L + D. What is y = f(x)? Let xd = 0.95. (L / V) min is the slope of the 2 points A and B.
