## Abstract

A transport tank with high capacity gas scrubbing includes a vertically extending interior wall horizontally dividing the transport tank into a gas scrubbing chamber and a fluid storage chamber. A floor grate is supported within the gas scrubbing chamber at vertically spaced distance from a bottom of the transport tank and defines a gas distribution space between the floor grate and the tank bottom. A gas distribution pipe is disposed within and longitudinally extends the gas distribution space. A gas inlet is fluidically connected to the gas distribution pipe and passes through an exterior wall of the transport tank. A gas scrubbing is material disposed within the gas scrubbing chamber above the floor grate. And a gas outlet is fluidically connected to the gas scrubbing chamber for venting scrubbed gases.

## Claims

### Claim 1

A transport tank with a vent gas scrubber, comprising:
a vertically extending interior wall horizontally dividing the transport tank into a gas scrubbing chamber and a fluid storage chamber,
a floor grate supported within the gas scrubbing chamber at vertically spaced distance from a bottom of the transport tank and defining a gas distribution space between the floor grate and the tank bottom;
a gas distribution pipe disposed within and longitudinally extending the gas distribution space;
a gas inlet fluidically connected to the gas distribution pipe and passing through an exterior wall of the transport tank;
a gas scrubbing material disposed within the gas scrubbing chamber above the floor grate; and
a gas outlet fluidically connected to the gas scrubbing chamber for venting scrubbed gases.

### Claim 2 (depends on 1)

The transport tank of claim 1, further comprising:
a fine mesh screen disposed between the floor grate and the gas scrubbing material.

### Claim 3 (depends on 1)

The transport tank of claim 1, further comprising:
an activated carbon foam mat disposed between the gas scrubbing material and the floor grate.

### Claim 4 (depends on 1)

The transport tank of claim 1, further comprising:
a first isolation valve fluidically connected to the gas inlet to receive a proportion of gas flowing through the gas inlet;
a second isolation valve fluidically connected to the gas scrubbing chamber to receive a flow of scrubbed gas; and
the first isolation valve and the second isolation valve fluidically connected to a test port.

### Claim 5 (depends on 1)

The transport tank of claim 1, further comprising:
a gas vent fluidically connected to the fluid storage chamber; and
wherein the gas vent is fluidically connected to the gas inlet to receive gas from the fluid storage chamber that is vented through the gas vent.
