3rd week

Mr Bakery asked me to go to engineering department to find a drawing of coupling P53201 C/B. There is a small crack on membrane (coupling component). Although coupling is still working, mr Bakery decided to purchase a new membrane for preparation.

Checked the condition of Calvert pump. Calvert pump is a kind of diaphragm pump. It is use to pump the exceed water inside the drain. Some of the pump is not in a good condition.

Met mr Izzat, he gave a way on how to settle a problem.

• define
• measure
• analyst
• improve
• control

One of the sample cooler (F59101-sampling line) is clogged. operated the cooler. Poured the chemical (Derket) in order to unclog the cooler

Sampling line is the point/place where the pH of the Boiler Feed Water is taken. the pH of the water determine the conductivity of it.

installed the sample cooler (F59101)

operated check valve at cogen. Check valve is use to prevent back flow, to make sure that the flow is one way, and to prevent pump from rotate in a wrong way.

2nd week

12-4-2010

• Change the filter element at S53201 (cooling water) and S33251B (amine)
• Have a meeting with Mr. Bakeri Wahab. He is the executive (mechanical supervisor) at area 5.
• He gave a brief overview on area 5
• Basically area 5 contains

utilities

• steam
• water
• air
• nitrogen gas
• flare

Sulphur Recovery Unit

• amine recovery unit
• sour water treatment unit
• waste heat boiler

Cogen

• Steam turbine generator
• gas turbine generator
• cooling tower

• went to AMT5 (cogen). met Mr. Zuhar
• He gave an overview on cogen
• cogen contains 5 gas turbine generators, 1 steam turbine generator, and 2 cooling towers
• cogen use a combine cycle concept
• combine cycle concept is the concept where the exhaust gas from the combustion chamber in gtg is recover and it is use as a heating element in a boiler. the steam is then use to generate power at steam turbine generator (stg)
• visit blowdown pit (an underground pond used to collect waste water from the plant)
• At TA mall, operate side glass. Side glass is one of pump part. it is use as an indicator to observe the flow of water to the pump.

• do the unclog tray at unit 67 (sulphur plant) [T 67205]
• process - change the tray and clean the previous tray. this is because the sulphur is extracted to the bottom of the tray.
• unit 67 is the unit where the process of changing the sulphur state from liquid to solid is done.
• do the bearing greasing at compressor (K53201 A/B) at unit 53
• clean tank T53205 unit 53
