The landfill gas collection, utilisation and surplus gas combustion acting in unison

In landfill gas utilisation the basic task of the control system is to harmonise three completely independent processes. On the one hand, there is the gas production of the landfill which is inconstant. (From a price point of view, hardly worthwhile to store the gas in a gasometer) On the other side the independent gas utilisation process, which orientates itself to the requirement of the ...

Modeling the Formation and Fate of Odorous Substances in Collection Systems

A conceptual model that simulates the formation and fate of odorous substances in branched collection systems is presented. The model predicts the activity of the relevant biomass phenotypes under aerobic, anoxic and anaerobic conditions in force mains and gravity sewers. The formation and fate of individual, malodorous substances in the bulk water, the biofilms and the sediments are modeled. The ...

Soil CO2 Flux Measurements -- Using the LI-8100 System to Collect Air Samples for Estimating Soil Trace Gas Flux

Air samples can be collected from the same air stream used to measure soil CO2 flux with the LI-8100 Automated Soil CO2 Flux System, for estimating the flux of trace gas, such as methane (CH4), ammonia (NH3), nitrous oxide (N2O), isotopic species, etc. This application note describes a simple method for obtaining air samples from the LI- ...

Application Data for Dry-Scrubbing Media in Collection Systems

Abstract Dry-scrubbing systems have been used for many years to control odors in wastewater applications. The systems have ranged in size from larger multiple bed scrubbers for force mains and large pump station applications to smaller single bed systems and modular systems in small wet wells, motor control centers, and other areas. Two reasons for their continued use are simplicity of ...

Collecting Data from the Field? Follow this Formula for Success!

A drill operator at an oil rig is looking tired and “out of it.” He’s yawning, his movements are slow, and he doesn’t appear to be paying much attention to detail. Immediately, the supervisor relieves the drill operator of his duties and reassigns the task. He quickly enters the work observation in his iPad. His device has an offline mode that will sync up with his ...

Innovative, Non-Intrusive Passive Soil Gas Collection Device Maps Large Carbon Tetrachloride Plume at the DOE Hanford Site, Washington -- 10501

Abstract Approximately 100 hectares (250 acres) were investigated as part of the passive soil gas (PSG) investigation that included multiple areas of concern. The objective of the investigation program was to rapidly identify potential source areas and guide future sampling events based on the frequency and magnitude of compounds identified in the survey. PSG sampling was the preferred ...

Efficient cyclone systems for fine particle collection in the pharmaceutical industry

The optimized design of gas cyclones is of particular relevance for the recovery of highly valuable products, such as in the production of active pharmaceutical ingredients (API) through drying systems such as Spray or Fluid Bed Drying (Shoyele et al., 2006). . Traditionally, these have been captured with reverse flow gas cyclones, but fine and low density particles remain difficult to capture ...
