FILTER FOR HUMIDITY CONTROL, TYPICALLY FOR CONTROL OF HUMIDITY IN A BULK LIQUID TANK

摘要

A filter is includes a housing and at least first and second adsorbent materials within the housing. The second adsorbent material has different characteristic from the first adsorbent material and is in series with the first adsorbent material. When assembled, a labyrinth arrangement is located between a first port in the housing and the first adsorbent material such that gas travels between the first port and the first adsorbent material by passing through the labyrinth arrangement. A filtration system and methods for humidity control of a liquid tank head space uses a filter, including first and second adsorbent and a diffusion channel or labyrinth arrangement

主权项

1. A filter for use with a moisture sensitive container; the filter comprising:
(a) a housing assembly having a first port and a second port; (b) at least a first adsorbent material within the housing; (c) at least a second adsorbent material within the housing assembly and layered in series with the first adsorbent material; the second adsorbent material having a characteristic different from the first adsorbent material;
(i) the first adsorbent material and the second adsorbent material arranged within the housing assembly so that gas travels between the first port and second port by passing through each of the first adsorbent material and the second adsorbent material; and (d) a labyrinth arrangement in fluid communication with the first port and being between the first port and the first adsorbent material; the labyrinth arrangement being located such that gas travels between the first port and the first adsorbent material by flowing through the labyrinth arrangement.
