Question 10

state why the acid Water system is constructed of stainless steel

Answer 10

due to the corrosive nature of the material
Sulfuric Acid >

Question 11

describe what kind of exchanger E-600a is

Answer 11

E-600a is a Thermosiphon Exchanger that uses 250# steam as a heat source, an evaporator, the steam is flow controlled to maintain an acid # of 250

Question 12

state what the concentrated acid Water is called

Answer 12

ep-306, transferred to HDO
D-900

Question 13

state where the concentrated acid Water is transferred to

Answer 13

to HDO for their process
from D-900

Question 14

Describe the function of EV-600

Answer 14

strips water, along with light acids, from the acid Water stream before being sent to a storage tank (D-900) for the feedstock for HDO

Question 15

state where D-182a pumps to

Answer 15

D-182a > level controlled
(P-
to D-185

Question 16

State the primary purpose of the Deepwell

Answer 16

the process material is neutralized in (D-403) and sent to (D-1401, 1402). from there it is flow controlled through a pre coat filter, then two trap filters then to a filtered Waste holding drum (D-1403) and then sent to wdw 99 or 408

Question 17

State the primary purpose of the sumps

Answer 17

The 900 and 1100 block sumps are for receiving sumps for Anone 2 ditches as well as Anones 1 oxidation system ditches. check toc every 6 hours and if in spec sent to wtp

Question 18

State the primary purpose of the 900 block

Answer 18

the cyclohexane transfer from Phillips and occasional cyclohexane barges are offloaded into (D-60B,C) Cyclohexane is then sent to the oxidation system in anone 2. Anolon barges are loaded and unloaded from (D-60A)

Question 19

State the purpose of (CT-1100)

Answer 19

Cooling tower supplies the cooling water for E-1523 A-D exchangers on T-1520

Question 20

State the purpose of EV-600

Answer 20

the acid Water is heated to remove water until it reaches a specified concentration
