Novinda AS-HgX Shows Superior Hg Capture in Dry-Scrubbing Environment

Category: Case Studies | Mar 28, 2014

In numerous field trials over the past two years Novinda Corporation has demonstrated efficient and effective mercury capture from flue gas at dry-scrubbed plants burning PRB coal. These trials were conducted at plants equipped with both Spray Dryer Absorbers (SDAs) and Circulating Dry Scrubbers (CDSs). Some units had selective catalytic reactors for NOx control. Particulates were captured either in fabric filters or electrostatic precipitators. Novinda's Amended Silicates AS-HgX was injected upstream of the dry scrubber device to capture mercury from the flue gas. The AS-HgX was removed in a downstream particulate control device and subsequently recycled along with the scrubber solids and fly ash.

Novinda Amended Silicates AS-HgX Determined to be Environmentally Safe for Fly Ash Disposal and Re-Use

Category: Whitepapers | Jan 30, 2014

Novinda Corporation sells a non-carbon reagent for capture of vapor-phase mercury from the flue gas of coal-fired power plants. This material is an option for utilities to meet the EPA MATS requirement for stack mercury emissions beginning in April of 2015. Amended Silicates AS-HgX consists of a bentonite substrate that is amended with a metal sulfide that acts as the reagent to capture mercury from the flue gas as mercuric sulfide, the most stable form of mercury found in nature as the mineral metacinnabar.

Typical Injection System and Silo Design for Amended Silicates

Category: Whitepapers | Oct 9, 2013

This specification covers the overall description, work scope, technical and performance requirements of a reagent injection system for a mercury emission control project. The specification requirements listed herein are based primarily on the work by Jenike & Johanson for Novinda and represent the minimum requirements to achieve consistent flow of the amended silicates material, and Novinda retains the right to review Owner’s design and drawings prior to fabrication and installation of the injection system. Designs deviating from these specifications may be considered on a case by case basis.

Novinda Product Shows Efficient Hg Capture in High SO3 Environment

Category: Case Studies | Apr 11, 2013

In a recent field trial Novinda Corporation demonstrated efficient and effective mercury capture of mercury from the flue gas at a plant burning Eastern bituminous coal. The trial was conducted at Santee-Cooper’s Winyah station Unit 4 in South Carolina. The host unit is equipped with a selective catalytic reactor (SCR) followed by parallel electrostatic precipitators (ESP) and wet flue gas desulfurization (FGD) modules. Novinda’s Amended Silicates (AS) mercury reagent was injected to capture mercury from the flue gas before it entered the wet FGD. Tests were run with and without simultaneous injection of hydrated lime. The host unit burns a medium sulfur eastern bituminous coal yielding a concentration of 20 ppm SO3 at the point of AS injection.
