Company ProfileThe Odox Process
Odor Control Systems
The control of nuisance odors is one of the most complex environmental problems facing today's industries. The Odox Process is an umbrella term for a wide range of techniques that Everstech employs to find solutions to industrial and agricultural odor issues.
We work with our clients to find the most appropriate solution for each situation. In cooperation with our partners in the relevant country, EversTech is responsible for project management, installation and all civil, mechanical and electrical engineering. We provide a turnkey service that encompasses every phase of the solution, from evaluation of the problem to designing and installing the equipment.
After detailed consideration of the requirement of each client's needs, EversTech engineers employ the following range of abatement techniques:
1. BIOFILTERS offer ease of operation and simple maintenance. They can cope with most odor types, including hydrogen sulfide, for example, at up to 50 ppm. The performance of biofilters is achieved by the biological consumption of the odor by living organisms within a fibrous, peat material. Additionally, specially formulated cultures are added at each site to optimize the filters effectiveness, thereby minimizing space requirements.
Biofilters offer a cost-effective solution but require large areas of land for larger flows and are not suited to fluctuations in odor level.
2. BIOSCRUBBERS can handle higher odor levels, typically up to 100 ppm hydrogen sulfide. These units occupy less floor space as they are built vertically. They are best suited to low to medium flow volumes due to sizing constraints to meet reaction residence times.
3. CATALYTIC ENHANCEMENT, using EversTech’s Catox technology, can offer enhanced odor removal as a result of improving the mass transfer characteristics of the system, thus enabling a smaller tower to be installed for the same application. This approach offers significant technical and cost advantages by:
- Improving the removal of mercaptans and sulfides.
- Giving the system the ability to remove the complete odor spectrum in a single unit.
- Allowing for the removal of ammonia and amines without the requirement for a second scrubbing stage.
4. The use of IONIZED AIR (Catox) technology has many advantages for odor control applications. The generation of negative and positive ions in a pre-determined ratio neutralizes odors at their source by the disassociation of odorous compounds. This technology has also been found to reduce corrosion. The overall effect is to improve the workplace environment and reduce running costs.
5. Low temperature CATALYTIC VOC EMISSION CONTROL SYSTEMS offer a cost-effective answer to reducing VOC releases, often the major factor in industrial-based odors. This technology offers total oxidation of VOCs through tailored adaptation. This approach is suitable for new equipment or retrofitting, with the payback potential from reduced heat costs, low or no NOx emissions and less expensive construction and maintenance costs.
6. ADSORPTION, either by activated carbon or alumina, is a technique applied to low odor discharge levels. The contaminants are collected in pores within the material and held there, thus removing them from the air stream.
