Maintenance of Fin-Fan Air Cooler

Maintenance of Fin-Fan Air Cooler in Refinery

In this topic today, we will clear how the fin fan air cooler maintenance are done so that we will disburse in step by step detail.

Fin Fan Air Cooler


Arrangement Before start work


1. To sabse Pahle aapke pass Work permit honi chahiye

2. Apke pass proper tools hone chahiye

3. Apko proper PPE jarur istemal karna chahiye aapke safety ke liye.

4. Aur aaj ham baat kar rhe h fin-fan ke maintenance ki to ye kaam hame height per rah kar karna hota hai to Safety harness ka upyog jarur kare.

5. Jarurat ke hisab se scaffolding erection jarur kra le

6. Equipment me koi fluid ho ya pressure ho to use bhi drain or release kar le.

7. Aur sabse khas  baat ki Blind list ke aadhar per inlet or outlet ka blinding kar le yaani ki equipment ka positive isolation kaam shuru karne se pahle jarur kar le.

Let’s Start Steps by Step Maintenance


1. Remove the plugs using torque wrench. ( Do not use hammer ring spanners and other hammering methods to remove the plugs because that will damage the threads )

2. Remove the old gasket rings without damaging the gasket area.

3. Now offer to inspection team for preliminary inspection.

4. Fix hydro jet water collection trays.

5. Now hydro jet the tubes.

6. After hydro jetting air clean the tubes.

7. Offer for Inspection

8. If ok, clean the gasket area good without damage.

9. Check the thread for any damage.

10. Clean the plugs good and check the threads.

11. Fix the plug with new gasket.

12. Tight plugs by torque wrench to required value.

13. Now fill the water and Hydro Test.

14. Identify leaks through Tubes/Plugs.

15. If no leak offer for inspection to the team.

16. Now drain the water and de-Blind.

17. Finally make good housekeeping and work safely.

Question Answer

Questios No1- What are the types of gaskets used in the fin-fan cooler plugs and material of construction?

Ans- Ring type gaskets are used and material of construction is soft iron, aluminium, stainless steel  and alloy.

Questio No2- What are the size of plugs used in fin-fan cooler?

Ans- 1 1/8 (28.5 mm) is the normal size. But 1 ¼(31.75=32 mm) and 1 3/8 (34.9=36 mm) plugs are also used.

6. If any fluid or pressure present in equipment then drain the fluid and release the pressure.

7. And the most important thing is to provide blinding as per blind list for the positive isolation of an equipment.

[TOP] 700 Refineries Supply Oil Products to the World

World Refinery, top refinery, petroleum
World of Refinery

Survey 


There are around 700 oil refineries everywhere throughout the present reality, yet - like oil - they are not similarly conveyed in all parts of the world. Their portrayal by area is significantly dictated by a few essential components; region of oil sources, region of serious oil items utilisation or populace thickness, region of oil transportation courses, monetary potential for refinery development, and so forth. Thus, refineries commonly vary by type and multifaceted nature of oil refining advancements (refinery unpredictability), introduced and used oil refining limit, and all the more as of late by innovative potential for getting exceedingly filtered oil items and very treated refinery emissions.
Notwithstanding the worldwide and provincial study of areas and refinery numbers, the paper covers their principle
attributes in the period from 1996 onwards, conveying to the fore broad patterns of changes and worldwide propensities of such changes in this part of industry. In spite of the fact that accessibility of information on existing refineries isn't basic and equivalent for all parts of the world, because of the endeavors put resources into information securing they give an image of worldwide circumstance and parity for this industry and delineate its progressions and patterns. Correlation of individual trademark refineries with normal or outrageous ones on the planet or in the area likewise ends up conceivable.

1. Presentation 


Oil refineries are the premise of the business branch called oil refining, where oil items are gotten by oil handling. Over the most recent quite a while the quantity of oil refineries in the world stands at around 700, and their items fulfill the interest of the advanced world. In contrast to the going before period, this period isn't described by refinery number development pattern, however essentially by certain stagnation brought about by constrained geographical oil holds and creation limits from one perspective and progressively discerning usage of refinery limits and utilisation of refinery items then again.

Refinery Survey

The paper shows a worldwide and nearby overview of refinery numbers and areas, just as their fundamental characteristics in the period from 1996 onwards, appearing
patterns of changes and worldwide propensities of these progressions in this part of industry.

2. Number of world oil refineries 


The ongoing turn of the thousand years is described by expression of development of world oil refineries into a slight decline, as represented in Table 1, which demonstrates the number of refineries by world locales from 1996 until 2008.
It is obvious that emphatically diminishing patterns in Western furthermore, Central Europe and North America caused a worldwide decline in refinery numbers. In the last ten to fifteen years a long time articulated changes are missing in refinery numbers in other regions.

3. Introduced world refining limits 


It is intriguing that the circumstance and equalisation of introduced refinery limits isn't proportionate to the quantity of refineries in a similar period. It is all around represented in Table 2 on territorial portrayal of introduced refinery limits from 1996 up to this point, which unmistakably demonstrates an increment, however with no signs of intonation towards conceivable reduction.

World Refinery Capacity

Normal refinery limits by locale in the period from 1996 until 2008 are appeared in Diagram 1.3,7

It is fascinating that most districts of the world show continuous increment of normal 5. World refinery complexity in the investigated period, while Central Asia and East Europe in specific demonstrate a more grounded abatement, along these lines followed by slow increment of normal refinery capacities.

4. World refinery usage 


Usage of refinery limits by and by is essentially practically identified with introduced limits and is commonly proportionate for similar periods, however not with a similar force in all areas, nor with equivalent complement in every one of the displayed periods, as appeared.

Table 3 which alludes to world refinery rough keeps running from 1996 until 2008.
Contrasts in usage of introduced refinery limits by locale are especially all around shown in Table 4, which translates the level of basically used in slowed down limits.

5. World refinery complexity


It is clear that use rate of introduced refinery limits is high in the Middle East, North and Latin America, Western and Central Europe, Asia and the Pacific. It is trailed by Africa, while East Europe and Central Asia are toward the finish of the rundown.


Table 6 indicates multifaceted nature proportion as level of refinery change limits in absolute refinery (refining) limit by world districts in the period from 1996 to 2008, and much better translates territorial contrasts for periods under review.


North American refineries have the most astounding normal intricacy proportions, which are fundamentally over those in other world locales. Refineries in Asia and the Pacific, Latin America and Western and Central Europe have average dimensions of intricacy proportions, while Central Asian, African and at the very end Eastern European refineries have the most reduced normal multifaceted nature ratios.
Strikingly, North American refineries have not demonstrated any pattern of further intricacy proportion increment in the most recent decade, while areas with normal proportion levels have the most escalated development pattern. In the event that the current pattern proceeds in the next years, worldwide changes towards assembly of districts with refineries of normal multifaceted nature proportions. And North American refineries can be normal, just as bipolarization due to additionally slacking of districts with low unpredictability proportions, with conceivable special case of Africa, if the pattern acknowledged in this thousand years proceeds.
