these are main utilities used in refinery.

Answer / dhaval modh

1)all types of water ie.DM Water,tappered water,sweet
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.....

PROCESS CONTROL - EXAMPLE 6.1 : In a Laplace Transform Table, the Laplace transfer function of f(t) is F(s). When d(t) = f(t) then 1 = F(s). When x(t) = f(t) then X(s) = F(s). If d(t) is the impulse of a spring when d(t) = kx(t), then derive the equation for the impulse of a spring as X(s) in term of k. Next question : A controller has a transfer function a and the other controller has a transfer function b. The overall transfer function of both controllers is ab. What is the transfer function overall when both controllers have similar transfer function 1 / (Cs + k)?

PROCESS CONTROL - EXAMPLE 6.3 : The differential equation is 3 dy / dt + 2y = 1 with y(0) = 1. (a) The Laplace transformation, L for given terms are : L (dy / dt) = sY(s) - y(0), L(y) = Y(s), L(1) = 1 / s. Use such transformation to find Y(s). (b) The initial value theorem states that : When t approaches 0 for a function of y(t), it is equal to a function of sY(s) when s approaches infinity. Use the initial value theorem as a check to the answer found in part (a).

Question 81 - (a) In natural gas pipe sizing, the length of the pipe from the gas source metre to the farthest appliances is 60 feet. The maximum capacities for typical metallic pipes of 60 feet in length are : 66 cubic feet per hour for pipe size of 0.5 inches; 138 cubic feet per hour for pipe size of 0.75 inches; 260 cubic feet per hour for pipe size of 1 inch. By using the longest run method : (i) Find the best pipe size needed for the capacity of 75 cubic feet per hour. (ii) Estimate the suitable range of capacities for the pipe size of 1 inch. (b) The maximum capacities for typical metallic pipes of 50 feet in length are : 73 cubic feet per hour for pipe size of 0.5 inches; 151 cubic feet per hour for pipe size of 0.75 inches; 285 cubic feet per hour for pipe size of 1 inch. By using the branch method find the best pipe size needed for the capacity of 75 cubic feet per hour when the length of the pipe from the gas source metre to the appliance is 52 feet.
