New Technologies Set To 'Disrupt' The Industry
For the unfamiliar, the term “disruptive technology” initially sounds quite bad, as though it describes something that gets in the way. Far from impeding progress, however, disruptive technologies actually accelerate progress exponentially by disrupting the status quo. Think personal computers vs. mainframes, or cell phones vs. land lines.
Thermal Mass Flow Meter Helps Mud Logging Contractor Meet U.S. EPA Flare Gas Emissions Monitoring Requirements
Upstream oil/gas production companies around the globe depend on mud logging service companies to analyze mud samples that help them maintain the correct direction for their drilling field operations. In mud logging, samples of rock cuttings from bore holes are brought to the surface by recirculating drilling media (mud) for analysis by a mobile laboratory to determine the lithology and fluid content of the sample.
Technology Qualification Of Liqui-Cel® Membrane Contactors For Deoxygenation Of Low Salinity Water For Polymer Flooding
Polymer flooding using low salinity water has been shown to improve oil reservoir recovery rates by altering the reservoir characteristic from an oil-wet state to a water-wet state. It has also been shown to be cost competitive with other Enhanced Oil Recovery (EOR) processes. The combined cost savings and increased recovery rate have prompted a lot of attention in the polymer flooding process with low salinity water in recent years.
Has Fracking Gone ‘Green’?
There are few topics more controversial these days than hydraulic fracturing ("fracking"). While the debate rages on as to whether fracking poses a risk to water quality, a new desalination technique addresses two other environmental concerns: water scarcity and greenhouse gas (GHG) emissions. Developed by researchers at the University of British Columbia (UBC), the breakthrough technology uses excess carbon dioxide created in the fracking process to desalinate the process water, making it available for water reuse. It also generates chemicals — hydrochloric acid and carbonate salts — that are valuable for many industrial applications.

4 Safety Considerations For Anyone Storing, Handling, or Transporting Substances
Substances regulated or substances unregulated may ultimately impact the environment, health, and water supply of others. The following safety considerations are advised for those who store, handle, or transport potentially dangerous substances. By Daniel L. Theobald, Environmental Services
How To Fix High pH And Comply With The Clean Water Act
When the Clean Water Act was enacted, one of the intentions of this legislation was to reduce the untreated industrial waste water burden on publically owned waste water treatment plants (POTW) so that industrial wastewater would only load the treatment plant to the same extent as ordinary household sanitary waste. Industrial facilities that generated process wastewater had to begin pre-treatment of the water before it could be returned to the local POTW.
MIOX’s On-Demand Generated Chemistry Boosts Production Of One Of The Major Puerto Rico Power Plants
In 2010, one of the Power Plants of Puerto Rico Electric Power Authority (PREPA) faced a crisis due to biological growth in their power plant’s cooling tower. The plant was using straight hypochlorite, which was not effective at controlling biological growth.
Cooling Tower Water Treatment: Substitution Of Conventional Biocide Treatment With Mixed Oxidant Solution
The substitution of conventional biocide treatments with MIOX Mixed Oxidant Solution (MOS) has resulted in a biocidal cooling tower water treatment process that costs less and is more effective than isothiazoline and bromine biocides.
Optimize Plant Burner Fuel-To-Air Ratio With ST75 Flow Meter And Reduce Boiler Energy Costs
The advanced ST75 Air/Gas Flow Meter from Fluid Components International (FCI), which measures fuel gas, process gas, inert gas, waste gases and air in small line sizes, is ideal for optimizing the fuel-to-air ratio for plant burner-boiler control, reducing plant fuel costs while protecting the environment.
