EXECUTIVE SUMMARY:
To determine the feasibility and estimates to convert the existing wet scrubber units to chemical injection for creation of a sellable byproduct of ammonia sulfate.

PROJECT OVERVIEW:
Gulf Coast Environmental Systems was asked to perform a feasibility project by a lighting company that manufactures light-emitting diode (LED) components. With a large amount of ammonia and hydrogen being released from the reactors during the process performed at their facility, they would need specialized equipment. The hydrogen is treated in an Incineration system (NOx created) with the remaining ammonia being removed using water only in the packed tower scrubbers. The blowdown (Ammonium Hydroxide) from the scrubbers is treated in an Acid Neutralization Systems (ANS) (converts to Ammonium Sulfate) before being discharged into the wastewater system. Waste surcharges apply based on the ammonium (NH4+) content in the wastewater.

The goal of this feasibility study was to determine the required steps and costs involved in using Sulfuric Acid in the scrubbers to get a controlled blowdown liquor that could create a viable revenue stream from an existing liability waste procedure. In addition, the need for the ANS system is hopefully eliminated along with the additional costs of discharging the uncontrolled wastewater. [Read more…]
