Belt Conveyors

Belt conveyors for bark drying and bark classification systems to transfer flow from an existing process.

Capital Costs:  $550,000

Sand Delivery System

A sand delivery system that starts out with pneumatic conveyors moving foundry sand to a storage hopper in the top of the structure.  After the sand descends through the structure it is heated and mixed with rosins.  From the mixer the mixed batch was transported along a traveling hopper to dump into one of six (6) sand molding machines.

Capital Costs:  $500,000

Carbon Storage Design

Project entailed the design of an activated carbon storage and pneumatic transfer system from 2-30 day storage silos to 3-3 day unit pair tanks for Hg emission reduction.  Detailed design included mechanical, piping, electrical, and CSA areas of the storage and transfer systems.

Capital Costs:  $150,000

Dust Collection Design

Project entailed the design of a dust collection system to collect dust emitted during bag change-outs for the baghouse on a fly ash silo.

Capital Costs:  $250,000

Generator Installation Design

Design for installation of 500kw diesel generator to provide power to critical plan loads (fire protection pumps, turbine lube oil, and packaging turning gear pumps) during a site power loss.

Capital Costs:  $270,000

Boiler Injection

Provided a basic engineering package design to store and inject into the boilers a powder activate carbon (PAC) for Hg removal.

Capital Costs:  $1,200,000

Sanitary Package Upgrade Project

The project permits the monitoring of the system flow rate and dissolved oxygen content.  The data collected from dissolved oxygen meter instrument will determine the aeration blower speed.  The effluent flow rate data shall be captured for compliance reporting.  A volumetric feeder shall be installed in a prefabricated fiberglass building, located adjacent to the sanitary package, to meter sodium bicarb material to the process.

Capital Costs:  $14,000

On-Site Controls Engineer, PLC/DCS

Two (2) controls engineers on-site to provide Modicon and Honeywell programming and troubleshooting.

Capital Costs:  $60,000

Flotation Process

Repipe and reinstrument the flotation process tank to increase the amount of material being processed.

Capital Costs:  $60,000

Paper Process

Changed process piping to increase through-put of paper process.  Includes the sizing of a new pump and 200 + feet of 8”, 12”, 14”, and 18” Sch. 10 stainless steel pipe.  Post floatation feed pump upgraded to 8400 GPM.  Sizing of piping for appropriate velocities is included.

Capital Costs:  $65,000
