Answer 1

C-402 is running to hard.

Question 2

AIC-5010 pv ranges.

Answer 2

High = 3.25
Low = 2.5

Question 3

While running, when should you run PIC-4010 in manual.

Answer 3

Near 10500 rpm.

Question 4

Stream 1 on G.C

Answer 4

V-403 inlet.

Question 5

Stream 2 on G.C

Answer 5

R-501 inlet.

Question 6

Stream 3 on G.C

Answer 6

R-501 outlet.

Question 7

What is AI-4002

Answer 7

S.G of incoming gas on V-403 inlet. Is also showen as a precent.

Question 8

What is AI-4022

Answer 8

C-401 own gas analyzer. Located in the comp building. Runs in a 70% to 73% range.

Question 9

What causes AIC-5010 to flunk to manual.

Answer 9

Bad pv
Bad G.C status
Pv changes by 0.1 in a single update.
No update within 600 seconds

Question 10

What does high PDI-5005 mean.

Answer 10

Syn loop is getting heavy.

Question 11

What are the black lines on the maintenance screen

Answer 11

Secondary line

Question 12

What is the yellow line on the maintenance screen

Answer 12

Primary line

Question 13

What direction is the wind the worst on a hot day.

Answer 13

West. It will blow warm air from the high line to E-509.

Question 14

When would you start to shut HIC-4012.

Answer 14

Low rates. This can help out if Nova trips.

Question 15

When would you expect V-506 to start gaining a level.

Answer 15

On hot days when C-402 is working hard. This will cause a C-402 trip.

Question 16

When would you start to close HIC-4012.

Answer 16

When C-402 is working hard. Closeing HIC-4012 will temporarily slow the loop.

Question 17

What can cause Nova’s compressors to overheat.

Answer 17

High pipeline pressure. Backing out of the loop quickly.

Question 18

What is the max 02 in the feed

Answer 18

Our scale does not go past 5 ppm. At 50ppm back out of the loop.

Question 19

How many starts from cold can C-402 take

Answer 19

2

Question 20

How can you save steam while on recycle.

Answer 20

Set operator margin to 0.

Reset additional margin

Question 21

How do you check to see suppresed alarms

Answer 21

Area Filter tag on delta V. Looks like German flag.

Question 22

1. When would you have FIC 4011 45% open?

2. Why would you do this?

Answer 22

1. During start up.

2. Gives a buffer for your steam load. You can open or close this based on if you need less or more steam.

Question 23

How can you steady the pressure in E-509.

Answer 23

You can shut a supply valve off to one side of E-509.

Question 23

What do you do if you have lost all E-509 fans.

Answer 23

Feed prep trip.

Question 25

Stream 4 on G.C

Answer 25

Purge gas stream.

Question 26

How can you increase TIC-6045 temp.

Answer 26

Shut bottom dampers. You can starve the furnace for air. You will see a sharp spike in combustables. If the temp is to high on TIC-6045 you can starve the furnace for air.

Question 27

What loop speed works best to control the heat up of the Borsig.

Answer 27

20 to 25 m/s. This will slowly warm the Borsig and not cause a large swell.

Question 28

On start up what does closing PIC-4005 do.

Answer 28

It will lower your H2 flow.

Question 29

How can you help smooth out a transition to half rates or flat.

Answer 29

Set HIC-4012 to 60% set FIC-4011 to manual and open it while closing HIC-4012.

Question 30

What does a higher then set point temp on TIC-6045 say about the super heater.

Answer 30

This tells you that you might be starving the super heater of air. TIC-6041 PV will drop while the control will call for more heat.

Question 31

What is one way to keep the steam system stable on start up

Answer 31

Hold gas back with FIC-4001 and pressure up Nova. This will keep the pressre off PIC-4010 so you dont have to speed up.

Question 32

At what point do you know that HIC-4012 is open despite their being room to open futher.

Answer 32

You stop seeing an increase in loop velocity.

Question 33

What is a surge event

Answer 33

When the margin decreases to less than 1%
