Week 3: Questions for $100!
« on: July 15, 2015, 04:44:57 AM »
1.   Which of these techniques can be used to identify crucial hazards in the early/conceptual stages of a process plant project
a.   HAZOP Study
b.   Dropped Objects Study
c.   Gas Release Consequence Modelling
d.   What-If Analysis
e.   Quantitative Risk Analysis

2.   In a Surface Oil & Gas Processing Facility, which of these locations is it more likely to have high noise levels
a.   Inlet Manifold
b.   High Pressure 3-Phase Separator
c.   Compressor station
d.   Crude oil Storage Tank
e.   30KW, 1450 RPM Centrifugal Oil Pump station

3.   If the Knock-out vessel connected to the only installed flare, experiences high-level, (when the associated liquid recovery pump is operating at highest evacuation rate) which of these response actions is indicative of a sound plant design
a.   Flare flame-out
b.   Total plant shut-down
c.   KO Drum pump trip
d.   Pressure relief Valve pops open
e.   None of the above

4.   A 3-phase separator, with MAWP of 1,000 Psig experienced a rupture from overpressure. The separator has adequately sized Pressure Safety Valves (PSVs) installed. In your opinion, which of these can be a possible root-cause of the incident.
a.   Extensive internal corrosion on vessel wall
b.   Improperly calibrated PSV
c.   Sudden pressure surge on inlet stream
d.   Manual valve on PSV piping inadvertently left in closed position
e.   All of the above
f.   None of the above.

5.   A centrifugal pump installed on vertical Surge vessel piping experiences multiple cavitation damage over a 12 month period. Which of these could be a major reason for this frequent failure
a.   Short-circuiting of inlet and outlet piping connections
b.   Adequate NPSH available
c.   Use of Eccentric Reducer on pump suction
d.   Short Pump suction piping
e.   Pulsation dampener failure on pump discharge piping.

6.   A booster pump, with a capacity of 10,000 BOPD is connected to a main Reciprocating Pump, with a rated capacity 10,000 BOPD. The piping distance between the pumps is 10m. What is the biggest challenge to this configuration?
a.   Capacity of the Booster pump
b.   Capacity of the Reciprocating pump
c.   The connecting piping distance of 10m
d.   The NPSH requirement of the main pump
e.   The relative volume capacities of both pumps.

7.   A flow line is always either 3”or 4” Nominal pipe diameter. TRUE/FALSE
