Home / Case Studies / Adsorber Installation on Toluene Tank Breather Vent
Adsorption Filter for a Toluene Tank
Project Feature
Installation of a toluene adsorption filter on a dissolver tank breather vent to capture displaced vapors during filling and emptying.
Production Process
Loading and unloading of toluene and dissolving additive into a dissolver tank.
Problem
Toluene vapors are released from the tank during filling/emptying, causing emissions and potential safety/environmental concerns.
Task
Design and supply an adsorption filter (adsorber) to capture toluene vapors with a maximum pressure drop not exceeding 0.5 atm.
Temperature
Wall temperature: 30°C (max), 18°C (min).
Design wall temperature: 30°C.
Design wall temperature: 30°C.
Gas/Dust
Toluene vapors. Diluted mixture of nitroesters and nitrocellulose in the tank.
Initial Data
Client Communication
Client:
Good afternoon!
Please provide a commercial quotation for a toluene adsorber for a toluene tank. The tank (dissolver) has a working volume of 3 m³. When toluene and the dissolving additive are loaded into it, air is displaced from the internal volume. We would like to install an adsorber on the tank’s breather vent.
Filling/emptying of the tank takes place every 3 hours.

Engineer Torch-Air:
To calculate the adsorption filter, it is necessary to know the rate at which the tank is filled (in L/min or m³/h).
It is also necessary to know the overpressure at which the toluene vapors are displaced, as well as the pressure rating of the tank. This information is required to calculate the maximum allowable pressure drop across the filter.
We can manufacture the filter based on a special activated carbon. Once we receive the required data from you, we will calculate the volume of the adsorbent charge, and the total toluene capacity of the filter will become clear.

Client:
The tank is filled at a rate of no more than 6 m³/h and emptied at a rate of 3 m³/h.
A sketch of the tank with dimensions and parameters is attached. We would like the pressure not to exceed 0.5 atm.
Technical characteristics and parameters of the tank:
Pressure, MPa (kgf/cm²): Working — 0.1 (1.0)
Design wall temperature, °C: 30
Allowable operating wall temperature, °C: Maximum — 30, minimum — 18
Working medium characteristics (composition): Diluted mixture of nitro esters and nitrocellulose
Design service life, years (max): 10
Number of loading cycles, max: 1000
Installation location: Indoors (heated area)
Internal volume, m³: 2

Scheme of the tank
Engineer Torch-Air:
Proposal for the adsorber is in the attached file.
Toluene capacity of the carbon: 145 g/dm³.
With an adsorbent volume of 0.2 m³ in the adsorber, one filling is enough for 29,000 g of toluene.
The filter resistance will not exceed 0.5 atm.
