To sample the gas of the BALLAST TANK, the sampling pump(P2) is used. To sample the gas of the PUMP ROOM, the
sampling pump(P3) is prepared. Each channel is controlled by the solenoid valve control. To regulate the gas flow and
check the flowrate, the regulation valve and flowmeter are installed. The moisture from the suction of pipe lines is filtered
by the filter and drained by
compulsion

Channel Sampling
▪
EV1 to EV40 and EV0-1 allow the control of the sampling line for PART1.
▪
EV41 to EV48 and EV0-2 allow the control of the sampling line for PART2.
▪
P2, P3 are the sampling pumps.
▪
EV0-1 allows the cabinet internal atmosphere control, or the P2 pump discharge; In addition, a solenoid valve EV0-1
allows to control the internal atmosphere of the Analyzing Unit, named channel 0.
Channel Purging
▪
EVA, EVE allows to proceed to an air purge of selected channel; After suction sampling of a channel, an instrument air
purge is started, in order to correct or prevent ingress of water, moisture, condensation, dust or foreign bodies.
Calibration
▪
EVB, EVF allow to drive the Calibration Gas to the detector(s).
▪
EVC allows to purge the water trap.
▪
Gas Detectors(GD) in Main Sampling Line(Ch.1~40): the Hydrocarbon gas Infrared detector is placed upstream P2
pump(GD on above diagram); other detector(s) is(are) placed downstream P2.
▪
Gas Detectors(GD) in PUMP ROOM Sampling Line(Ch.41~48): the Hydrocarbon, O
2
and H
2
S gas detectors can be
placed upstream P3 pump(GD on above diagram); other detector(s) is(are) placed downstream P3.
