Manufacturers can treat contaminated waste or by-products and reduce odorous vapours with engineered solutions from Simdean Group Ltd, part of Operational Group.

We understand the challenges across a wide range of sectors, from pharmaceuticals to food and beverage processing. We have helped many manufacturers to treat emissions and meet environmental regulations, along with optimising their production systems, leading to significant benefits and returns on investment.

One example of our work in pharmaceuticals is with a large research-and-production facility in Limerick, Ireland.

A by-product of the plant’s production process is liquid waste, which is classed as contaminated and emits odorous vapours. The waste water is stored in large, glass-lined tanks where it is treated and purified by chemical processes before being discharged safely.

The client contacted us to discuss the odourous vapours.  We surveyed the plant and designed an appropriate new carbon absorption system to contain and eliminate the problem.

In this case, the best solution was an annular bed carbon absorber, powered by a fan unit via a fresh air mixing damper and system of ductwork. The system was designed to be capable of handling 5,200 m3/h of contaminated air.

The carbon absorber is housed in a GRP-clad polypropylene housing and is internally split. One section contains general-purpose activated carbon to remove basic and neutral odorous components in the gas stream. The other section contains impregnated activated carbon to remove acidic odorous components and act as a polishing bed.

The bulk of the system and absorber is installed on a purpose-designed steel platform with ladder access for easy maintenance.  The entire system was commissioned within two 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.

The system includes odour-monitoring and carbon-testing facilities, allowing operators to determine the most cost-effective time to maintain the system and replace activated carbon. Carbon bed unloading and reloading can easily be achieved, thereby minimising shutdown time.

All Simdean/Operational systems are designed for flexibility of operation. Running capacity can be trimmed to suit the load which ultimately keeps power consumption and energy costs low.

Absorber housing, plastic ductwork, field wiring, controls, access ladders and steelwork is designed and manufactured in accordance with relevant standards and regulations.
