Abstract
Embodiments relate to systems and methods for fluidization in industrial hygiene applications. The method includes collecting air samples of contaminants onto the surface of fluidized activated carbon particulate as opposed to fixed-bed particulate. The adsorbates include toluene (a cyclic compound) and n-hexane (an open-chain compound). The obtained results are analyzed and discussed in terms of breakthrough times. The input parameters are the initial concentration of toluene or n-hexane in the air feed stream and the amount of the sorbent used. The feed flow rate is at 2 liters/min, and the temperature and humidity are kept constant at their prevailing laboratory conditions, i.e., 22±2° C. and 34±2% RH, respectively.
Claims10
A system for an industrial hygiene application, the system comprising:
- an air compressor configured to receive an air stream;
- a pressure regulator configured to regulate a pressure within the air stream;
- a precision rotameter configured to split the air stream into a first air stream and a second air stream, and to regulate a flow rate of the first air stream and the second air stream;
- a volatile organic compound (VOC) generator configured to receive the first air stream, wherein the volatile organic compound generator comprises a plurality of first metal bubblers;
- a humidity generator configured to receive a portion of the second air stream, wherein the humidity generator comprises a plurality of second metal bubblers;
- and
- a fluidized bed sampler for receiving a combination of the first air stream and the second air stream.
