The MVP is a low total horsepower system with a low liquid caustic pressure. Liquid
and gas flow are co-current with a liquid rate to each stage matched to absorption
performance, so there is no possibility of caustic starvation.
The caustic solution is supplied to each of the six venturi stages by a vertical sealless
recirculation pump. The system is available with either one or two pumps.
Advantages of the system include the lowest profile system avaliable from
SEVERN TRENT with the capability to handle the worst case release rate of liquid
chlorine based on total vaporization of the chlorine. The chlorine concentration at the
exit of the system is reduced to a level below that required by the prevailing fire
codes. Since there is no packing in the system, less surface area is available for
carbonate buildup during down periods. Therefore, a longer caustic solution service
life is expected.
The MVP 3000 and 5000 are designed to neutralize a one ton chlorine portable tank at
a leak rate of up to 437 pounds per minute throughout the leak event.
At only 8' tall, the fan-driven Multi Venturi Packless
(MVP) scrubber is SEVERN TRENT'S lowest profile
emergency chlorine scrubber. The fan - driven
MVP 3000 system consists of six venturis in
series with a downstream fan which keeps the
entire scrubber system under a negative pressure.
Even with fan failure, the venturis will provide
a system capacity of about 2/3 of the rated
capacity, or 2000 cfm for a 3000 cfm system.
