Boiler plant Refrigeration plant

Introduction to company Departments of our study.

Safety induction & practice. Utility Department. Plant maintenance Department. Workshop & fabrication.

Manufacturing processes

High temperature pressurized steam generation, through 3 different boilers.

Refrigeration system for generation of cooling water, chilled water, brine water, air supply, Nitrogen supply.

Welding, HDPE pipe cutting through HDPE (High Density Poly Ethylene) cutter, drilling process under workshop department.

Manufacturing processes.

Specification of Boilers.

• In transpek all boilers are fuel based boilers to fulfil the demand of Hot Oil and high Tempreture Steam.

• Generally 4 TPH to 8 TPH capacity steam is generated in transpek,

• In Transpek pressure of steam required is 4.2 kg/cm2, pressure in the boiler can be regulated upto 10.5 kg/cm2 if required.

Manufacturing processes.•In this vessel water is heated at boiling point (100o C) to obtain steam, this steam is pressurised in vessel to obtain high temperature steam (150o C)

•This boiler are comprises of mounting & accessories, which are installed for safety and higher efficiency.

Manufacturing processes.

Specification of cooling tower.

• In the cooling tower temperature difference obtain is of 2o to 5o C

• In this hot water vapour is removed from top of tower with help of induced fan. While more cooling can be done by modification in design and refrigerant.

Manufacturing processes.

As shown in figure above, in Induced draft cooling tower there is induced fan at top of tower, which is design in a manner to suck up air from inside the tower and throw it out, while on tower body fins are provided, such that it can allow passage for air to flow in tower, water used as refrigerant is constantly poured from top of tower.

Problem Identification. In Transpek, as it is an chemical based

plant, the whole manufacturing practice are done with chemical, different hazardious, toxic gas or liquid are manufactured here.

This chemical are also corrosive which lead the corrosion in plant site, Equipments like metal pipes, metal vessel or storage vessels are also corroded.

Problem Identification.

Problem: 1

To prevent corrosion routine and schedule maintenance work are carried out, in Transpek.

while its is continues working plant, mostly corroded pipes or vessels are replaced because its more economical then shut down.

Thus replaced of this pipe line, or creating new network of pipe line in plant create an rumble.

Problem Identification.

•Such type of unwanted pipe line network creates an Mesh, and leads to confusion.•This mesh may create problem at time of critical situation like accidents and maintenance.

Problem Identification.

So to avoid this confusing network of pipe line in plant, an suitable maintenance scheme should be adopted in which there should be an removal of unwanted pipe line should be done.

Problem Identification. Problem : 2

The problem of corrosion is also an major issue in chemical plant, mostly in transpek ,metal pipe, metal storage vessel are corroded due conduction and storage of corrosive chemical.

Problem Identification.

 Solution to the Defined Problem. Our little research on Engineering material, suggest

that rather than the use of metal in pipe line, vessel or storage container, the use of material FRP ( FIBRE REINFORCED PLASTIC ).

Its is unsaturated polyester and vinyl ester resins. The

main fundamental of this material is This versatile polymer materials immediately found acceptance in aerospace, construction, transportation, the infrastructure, and industrial process equipment, where their unique properties brought value and new solutions to the practicing engineer.

Solution to the Defined Problem. Because of its superb corrosion resistant

properties, composite fiber reinforced plastic (FRP) has displaced other more costly metals in many industrial process equipment, e.g. tanks, piping, duct and hood systems, reaction vessels, etc.

This material is highly Ductile, this material can duct concentrated acid easily, its is also resistive to high tempreture, and it is quit cheaper to install, thus it can be consider as the future of material Engineering.

Solution to the Defined Problem. Many other properties of FRP is light in weight, easy is

transpotable, and can resist any temperature, as the plant of Transpek is situated in south eastern Gujarat, it was moderate tempreture and atmosphere condition, so use of FRP is advicable.

The main factor of this material is that it can be used in any practice like piping, underground piping, vessels, storage tank, etc.

Another option of choice than FRP is fibre ciremic coating in pipes, which is also resistive to corrosion and also duct concentrated acid.

Fiber Reinforced Plastic. Advantages:•  High strength • Resistance to corrosion • Fast & easy installation• Composites cost less than stainless or high-

carbon alloy steel components that might be used in highly corrosive environments.

• FRP can conduct concentrated acids.• Easily mouldable. And Durable.

Fiber Reinforced Plastic.

Fiber Reinforced Plastic. Disadvantages:

At high temperatures the material's strength decreases and deflection increases.

These materials continue deflecting under heavy, sustained loads (creep).

Can not handle high pressurized fluid.

 Limitations in Implementing the Solution.

Thus FRP being very versatile conducting material can not be used in boiler pipes.

FRP can only be restricted in utilization for conducting acids or any other fluid.

 Conclusion.

The use of best maintenance scheme, is very essential for avoid any mesh pipeline network.

The use of FRP (Fiber Reinforced Plastic) is more appropriate than metal pipes.
