Carbon Filter Installation and Relief Stack Modification

The project involved the design development of a new carbon filtration system to be installed between the existing Cyclone Fan and the associated relief stack to atmosphere.
The objective was to integrate the new carbon filter into the existing operating plant while retaining the required process flow path and accommodating the surrounding infrastructure.
DMD was appointed to deliver the piping, mechanical, civil and structural design elements, with EC&I works undertaken separately by the client or other appointed parties.
The design included modifications to the existing pipework and ductwork, development of the new equipment arrangement, supporting infrastructure and the civil foundation required for the filter installation.

The client required a new carbon filter to be incorporated into an existing relief system between the cyclone fan and the atmospheric discharge stack.
The new equipment had to be positioned within an established operational area containing existing pipework, ductwork, structures and plant infrastructure.
Existing pipework and duct routes required modification to accommodate the filter while maintaining a practical and coordinated flow path.
The arrangement needed to provide suitable support for the new and modified systems, together with safe access for operation, inspection and maintenance.
Piping, mechanical and structural interfaces had to be coordinated with EC&I works being delivered by the client or other third parties.

Laser scanning and point-cloud data processing
Site surveys and existing-condition verification
Development of the equipment and ductwork routing
Redesign of existing ductwork to accommodate the new installation
Mechanical integration of the carbon filter with the existing cyclone fan and relief stack
Secondary steelwork and supporting infrastructure design
Civil foundation and equipment-base design

A laser scan of the project area was completed and processed to establish an accurate record of the existing installation.
Site surveys were undertaken to verify existing equipment, pipework, ductwork, structural interfaces and available installation space.
Existing systems were redesigned where required to accommodate the new filtration equipment.
Pipe and duct support requirements were developed alongside the routing to ensure the proposed arrangement could be safely supported.
The civil base and structural elements were coordinated with the equipment loads and proposed installation arrangement.
