Carbon Adsorption System at Food Processing Plant

Carbon Adsorption System at Food Processing Plant

Co. Kildare, Ireland

Simdean Group have successfully designed, installed and commissioned a new carbon adsorption system at a large food processing plant situated in a town called Naas in Co. Kildare, Ireland.

The Problem

The client’s production facility prepares, cooks and packs a wide range of soup products including stocks, sauces, marinades, glazes & pastes on an increasingly large scale.

As a consequence of this process, cooking odours are produced which being airborne tended to drift out of the production areas and over the surrounding housing estates thus generating complaints from the neighbourhood. Since the factory operates around the clock it became essential that action was taken to reduce the level of odour emanating from the site.

The Solution

The food production company contacted Simdean Group Ltd. who were very happy to discuss the issues, survey the site, and design an appropriate system in order to solve the odour problem. In this particular case the best solution was to use a large carbon adsorber, powered by a fan unit via a fresh air mixing chamber and system of ductwork. The system was controlled via various pressure and temperature sensors located within the system and feeding all information into a PLC. The whole system would be automatically controlled via auto-dampers to regulate temperature and humidity and energy use is minimised by the use of inverter control on the prime mover in this case a centrifugal fan unit.

The Installation

As physical space on the site was very limited it was decided to build the whole system at a 5-metre-high level over the top of a busy loading bay, logistically difficult but Simdean developed an efficient design for a structural gantry over the loading bay which proved very successful. The 25tonne odour control system was installed onto the steelwork which also provided access via a stairway up to the plant to enable ease of maintenance in the future. Mechanical and electrical installations were completed in just over three weeks and the system was handed over on time and within budget.


The entire system was commissioned within 3 days and after trials and a running in period the customer was extremely pleased with the result. All odours from the process have been effectively contained and are treated efficiently by the system.

Included within the system is a built-in facility to enable on going odour monitoring and testing of the carbon within the unit thereby allowing operators to determine the most cost-effective time to maintain the system and replace the activated carbon.
