  • New laser-based dust emission monitoring system

    Abstract A new generation of continuous particulate matter concentration monitoring instruments is presented, covering a measuring range of 0 to 1000 mg/m3. The laser-based scattered light instrument gives an improved stability as well as excellent resolution in the low range. This enables high concentration measurement as well as especially low emission monitoring down to 0.01 mg/m3 with a ...

  • Marine Industry experience with Aalborg Industries

    Port Authorities and Governing Bodies state that a ship cannot emit smoke of >20% opacity for more than 3 minutes when in port. The IMO set similar limits for on-board incinerators. The DSL-220 Opacity Monitor has been used successfully to measure smoke emissions from diesel engines, incinerators and boilers on board ship ensuring that environmental concerns are ...

  • An analysis of extinction coefficients of particles and water moisture in the stack after flue gas desulfurization at a coal-fired power plant

    Two important factors that affect in-stack opacity—light extinction by emitted particles and that by water moisture after a flue gas desulfurization (FGD) unit—are investigated. The mass light extinction coefficients for particles and water moisture, kp and kw, respectively, were determined using the Lambert-Beer law of opacity with a nonlinear least-squares regression method. The ...

  • Navigating NSPS subpart Db for boilers: a case study

    Over the past year, Trinity assisted a chemical company with the permitting and installation of a new 220 MMBtu/hr package boiler. The new natural gas-fired boiler replaces coal-fired units that were installed in the 1940s. Navigating through the numerous, and at times conflicting, regulatory requirements applicable to such a unit has been challenging. With careful planning and implementation, ...

  • Proposed boiler MACT sets aggressive emission limits

    On June 4, 2010, U.S. EPA proposed National Emission Standards for Hazardous Air Pollutants (NESHAP) for industrial, commercial, and institutional boilers and process heaters at both major and area sources of hazardous air pollutants (HAP) emissions.  EPA proposed separate rules for units at major sources of HAP emissions (greater than 10 tons per year [tpy] of any single HAP and/or greater ...

  • Replacement of a Multiple Hearth by a Fluid Bed Incinerator - The Greensboro Experience (PDF - File size 50K)

    ABSTRACT The incinerator at the T.Z. Osborne Plant in Greensboro, North Carolina burns sludge from its own Waste Water Treatment Plant and sludge pumped from the nearby North Buffalo plant. The two plants have a combined capacity of 36 million gallons per day of wastewater. In 1992, the Osborne plant concluded a study evaluating its options for future municipal sewage sludge disposal. The ...

  • While Oil Prices are Down, Get Up on Compliance

    It’s no secret that the oil and gas industry has taken a hit lately, with per-barrel prices dipping to as low as $27. The saturated market and low prices have many companies putting a hold on drilling. While no one in our industry likes dipping oil prices, there are two things you can do to weather the storm until those prices take a (much welcomed) upward turn: Stay up to date on ...

  • Global solution: Gas and particulate analysis in Cement industry

    Cement plants are increasingly required to install continuous emission monitoring systems (CEMS). While these represent a significant financial outlay, a range of other factors also need to be considered when selecting a suitable CEMS. To the inexperienced, selecting a suitable CEM can mistakenly be considered as simply ensuring that the applicable national regulations (eg MACT in the USA, ...

  • Effective Temperature Control for Cement Kiln Off-Gases

    INTRODUCTIONEffective off-gas temperature control without unwanted side effects can be achieved in many cement plants with state-of-the-art evaporative spray technology. Gas temperatures have elevated in recent years from as low as 180°C to over 370°C. This is coincident with a higher proportion of 'dry' operation kilns. Evaporative cooling water sprays in conditioning towers, ducts or at the ...


  • Controlling Stack Emissions in the Wood Products Industry

    Electrostatic precipitation has been a reliable technology since the early 1900's. Originally developed to abate serious smoke nuisances, the manufacturers of zinc, copper, and lead quickly found electric gas cleaning a cost efficient way to recover valuable product carried out of the stacks from furnace operations. Today electrostatic precipitators are found mainly on large power plants, cement ...


  • Who Owns Groundwater?

    California’s drought underscores the need to improve how the state - and the rest of us - divvy up a resource in demand. Grapevines march across wires strung along rolling hills, their little trunks improbably supporting heavy black fruit. Cindy Steinbeck’s family has been farming this land since 1920. They grow Zinfandel, Viognier, Cabernet, Merlot, and Petite Syrah grapes but are ...
