ENHANCED MERCURY COLLECTION USING THE INDIGO AGGLOMERATOR
RODNEY TRUCE, JOHN WILKINS, ROBERT CRYNACK AND WALLIS HARRISON

Recent regulations in the US require Mercury emission control on coal fired power stations. Mercury is considered a major health hazard because it concentrates in the food chain and, in particular, may result in very high concentrations in some fish. The Indigo Agglomerator enhances Mercury collection by increasing the interaction between the Mercury, in the form of elemental or ionic molecules contained in the gas stream, and the adsorbent, either injected Activated Carbon or using the LOI from the combustion process. Initial tests have shown a factor of four enhancement of the Mercury removal when an Indigo Agglomerator is installed in front of an electrostatic precipitator. This is in compliance with the long term EPA requirements in the US.

ADVANCED PARTICULATE AND MERCURY REMOVAL TECHNOLOGY
ROBERT TAYLOR

Abstract

Historically, coal-fired boilers have utilized electrostatic precipitators for particulate removal.  As environmental regulations become more stringent and enforcement becomes more consistent, electrostatic precipitators are challenged to provide continuous compliance.

As a result, many coal-fired boiler operators are considering pulse jet fabric filters to provide continuous particulate compliance. However, there can be operational penalties experienced when this switch is made.

Traditional pulse jet fabric filters introduce increased pressure loss to the system. This loss is in the range of 150 to 250 mm of water. In addition, compressed air used to pulse the filters can account for a major operating expense. The requirement to replace filter bags every three to four years is a major expense.

Based on the need to increase particulate removal efficiency while minimizing the impact on plant operating costs, an alternative to a conventional pulse fabric filter is required.
