  • NH3 Slip Monitoring in Fluidized-bed Catalytic Cracking Using the LDS 6 Gas Analyzer – Case Study

    Fluidized catalytic cracking (FCC) units are used in refineries to convert low value heavy oils into more valuable lighter compounds. Cracking units are sources of emissions of pollutants (e.g. NOx) and must comply with concentration permits set by local or federal authorithies. Modern technologies are applied to reduce the content of pollutants and to monitor certain gas compounds (here: NH3) in ...

  • Ammonia Vent Line Gas Detector

    The LPT-A Vent Line Ammonia Transmitter (P/N: LPT-A-VLT-NH3-S) is designed for continuous monitoring of ammonia levels in the vent lines of refrigeration systems caused by equipment failure or system over pressurization. Slow leaks of refrigerant can be costly over time and a dangerous situation could present itself if a high pressure release were to occur. The VLT provides continuous, ...

  • Nitrogen removal and ammonia-oxidising bacteria in a vertical flow constructed wetland treating inorganic wastewater

    Nitrogen removal performance and the ammonia-oxidising bacterial (AOB) community were assessed in the batch loaded 1.3 ha saturated surface vertical flow wetland at CSBP Ltd, a fertiliser and chemical manufacturer located in Kwinana, Western Australia. From September 2008 to October 2009 water quality was monitored and sediment samples collected for bacterial analyses. During the period of study ...

  • MONITORING & ALERT NETWORK in response to the health problems of Sargasso algae

    Martinique has been facing a major health problem in recent years. Indeed, since 2011, the unprecedented phenomenon of massive stranding of Sargasso algae has affected the Atlantic and southern coasts of Martinique. This phenomenon is the origin of a smelling gas emanating from the putrefaction of algae, among these gases hydrogen sulfide (H2S) and ammonia (NH3). Beyond the olfactory discomfort, ...

  • Monitoring NH3, N2O, CO2 and CH4 emissions

    In France, as in other countries, there is a need to improve knowledge of greenhouse gas and ammonia emissions from livestock production with various management options. The aim of this study was to quantify the NH3, N2O, CO2 and CH4 emissions from two pig solid manure heaps, turned and not turned, in order to examine the effect of turning on gaseous emissions and to obtain additional information ...

  • Monitoring Multiple Gas Hazards in Ice Arenas

    The equipment used in an arena such as an ice re-surfacer, ice edger, floor sweepers, lift trucks and other special equipment are more often powered by fuel than electricity. The exhaust produced by the gas, propane or diesel fuel powered machines emits, into the air, carbon monoxide (CO), nitrogen dioxide (NO2) and particulates. Ammonia (NH3) is commonly used in the ice chiller mechanical room ...

  • BUMP TESTING AMMONIA (NH3) SENSORS

    Bump testing a gas sensor involves flowing a concentration of gas that is slightly higher than the Low alarm setpoint of the gas detector for a short period of time (1-2 minutes or less). The purpose of a bump test is to confirm that the sensor responds to the presence of gas, the low alarm will activate and the gas detector overall ...

  • Online Odors Monitoring in Waste Water Treatment Plants

    Odors are very distinct air contaminants as they generate nuisances (see note at the end). The factors playing a role in the determination of odor annoyance are : odor concentration and intensity, frequency, appreciation, duration, synergy and location. Chromatotec proposes an automated solution to well identify the origin and the level of odors. Technology Description We offer a ...

  • Low-pH Ammonia Oxidation at a Biological Nutrient Removal Facility

    ABSTRACTMcAlpine Creek Wastewater Management Facility (MCWWMF), owned and operated by Charlotte Mecklenburg Utilities (CMU) of Charlotte, North Carolina, is permitted to treat 64 million gallons per day (mgd). Along with MCWWMF, three CMU treatment plants discharge effluent into the Catawba River just upstream of the South Carolina border. CMU worked with North and South Carolina regulators ...

  • Major waste management company and cbio combine resources, to resolve a breach of ammonia consent, in a large wastewater treatment plant case study

    The WWTP itself is located in the East Midlands, and treats dairy waste from a large processing plant, treating c1,500m3 of effluent per day. On 30th July the ammonia (NH3) levels in the permeate from the MBR at the plant began to increase. The effluent plant discharges to a river and as such, the consent limit is stipulated by the Environment Agency at 4mg/l. Within three days, the ammonia ...

  • Typical Sensor Location Considerations

    The sensor mounting location within a space may be dependent on many variables. There are no specific formulas since each application will have it’s own determining factors and priorities. These include, but are not limited to: source of gas: Is the source a combustion exhaust from a vehicle or furnace or a vapour from a tank spill, pipe leak, or faulty valve? density of ...

  • Real-Time Control Optimizes Extended Aeration Processes

    The population of Hillsborough County, Florida has doubled since the Valrico advanced wastewater treatment plant (AWTP) was built in 1990 to treat the sewage of several small communities west of the City of Tampa. When it began operation, the Valrico AWTP capacity was only 4 MGD; small when compared to Tampa's 96 MGD Howard F. Curren AWTP located not far to the east. But Valrico serves as a very ...

  • Fast, simultaneous and continuous monitoring of NOx and NH3 in DeNOx applications

    In DeNOx systems using urea injection with ammonia (NH3) as a reducing agent, the flow rate and control of NH3 must be continuously adjusted and controlled to prevent excess NH3 emissions (slip), to reduce environmental impact and cost of reagents. To optimize this process, it is essential to use an emissions analysis system for simultaneous and continuous monitoring of NOx and NH3. For preparing ...
