A gas absorption box includes a box body, at least one gas absorption member and an outer housing assembly, the box body has an accommodating cavity; the gas absorption member is elastic and is provided with a first inner cavity, and the first inner cavity is in communication with the outside of the box body; and the outer housing assembly is arranged in the accommodating cavity and is elastically connected to the box body, and the outer housing assembly has a second inner cavity for accommodating a gas absorbent, the second inner cavity being in communication with the first inner cavity, and the gas absorption member being capable of absorbing gas for the second inner cavity. When battery powder or some positive-electrode materials for batteries are transported, hydrogen generated by the battery powder or some positive-electrode materials for batteries gathers towards the upper portion of a ton bag.

A method for reducing emissions from a vessel includes isolating the vessel from a downstream fluid flow line, purging a fluid from the vessel by injecting purging media into the vessel to push the fluid through a check valve of a vent tubing and into the downstream fluid flow line, and draining the purging media from the vessel. A first end of the vent tubing is coupled to the housing of the vessel, and a second end of the vent tubing is coupled to the downstream fluid flow line. Further, the vent tubing includes a check valve disposed between the first end and the second end, and the check valve is configured to allow fluid to flow from the housing to the downstream fluid flow line.
