U.S. Air Force DOD Project - Case Study
Environmental Issues Controlling the off-gas from a remediation project, where high concentrations of petroleum hydrocarbons are present, can be a difficult if not dangerous process when utilizing internal combustion engines and conventional oxidation technology. In more recent years, the use of high vacuum pumps to accomplish both liquid and gas phase extraction — sometimes referred to ...

Application of gas detector sensor
How a gas detector works. Gas detection systems are safety technology products, best used to protect workers' lives and ensure factory safety. Gas detection systems are designed to sense the concentration of hazardous gas vapors, trigger alarms and beam light signals -- and initiate responses before hazardous situations arise for employees, assets and the environment. They are an important tool ...

Refinery remediation: fuel recovery and recycling
Introduction The site is a former refinery that occupied approximately 64 acres of land in West Texas. Refinery operations produced all grades of gasoline, tractor fuels, diesel, distillate products, and fuel oils and operated between 1939 and 1954. As a result of past waste management practices, releases to soils and ultimately ground water occurred, resulting in the formation of a ...

Indoor Dewatering Plan Successful for Palm Beach Florida Mall
Griffin Dewatering was hired to provide a workable dewatering plan to facilitate the“facelift” of a swanky mall in Palm Beach — all while maintaining a low profile to accommodate everyday mall business. When the Palm Beach, Fla., area was growing into the north end of the county, it became apparent that a new shopping venue was required. After all, these residents ...

Fixed Versus Portable Gas Detection – Which Is Better?
Did you know that workers are needlessly injured every year as a result of leaking toxic or combustible substances? Such incidents are known to involve a wide range of hazardous gases (including ammonia, carbon monoxide, chlorine, hydrogen sulfide, hydrocarbon vapors and so on). The sad reality is that most of these accidents are avoidable if only the workplace is adequately monitored. This leads ...

Analytical Devices for the Measurement of Water Vapor and Hydrocarbon Dew-Point in Natural Gas
Introduction The determination of water vapor (water dew point) is crucial in the processing, custody transfer and transport of natural gas. High levels of water vapor in a natural gas stream can lead to a number of problems which include the formation of hydrates and the contribution to corrosion of plant and equipment. Furthermore, water vapor present in natural gas streams affects the overall ...

Doped nano–phase tin oxide thin films for selective gas sensing
The paper deals with the development of ethanol gas sensing films of tin oxide nano–particles which are insensitive to saturated aliphatic hydrocarbons, such as gasoline vapours. Stannous alkoxide (particularly iso–propoxide) and tin 2–ethyl hexanoate in solution have been used for fabrication of tin oxide films on alumina substrates with two pre–fabricated gold electrodes. For achieving ...

Controlling Fugitive Emissions, Part 1: Close Capture Hooding
Fugitive emissions, in their simplest form, are the uncontrolled release of gases to the atmosphere. Each one of us may contribute fugitive emissions when we fill our automobile gas tanks. The displacement of air inside the gas tank causes gasoline vapor emissions (hydrocarbons) to exit out the fill spout (un-controlled) to the atmosphere. Some states require the use of "Vapor Recovery" nozzles ...

Pyrolysis Process - Take Waste Plastics as Example
Pyrolysis is a process that involves the thermal decomposition of organic materials at elevated temperatures in the absence of oxygen. This process can be applied to various materials, including waste plastics, to convert them into valuable products such as liquid fuels, gases, and char. Here's an overview of the pyrolysis process, particularly focusing on waste plastics: Feedstock Preparation: ...

Combining Spectroscopy and Separation Science in Process and Emissions Monitoring
ABSTRACT Ultraviolet (UV) absorption spectroscopy provides rapid real-time analysis of many species of interest to industrial monitoring. In some applications, the presence of other interfering species obfuscates the measurement of interest and makes accurate and reliable analysis of trace components difficult. The use of auto-carrier, frontal elution chromatography in conjunction with a process ...

The Eco-Smart Choice: Tire Recycling for Oil Recovery
Tires are an essential part of modern transportation and industry, but their disposal poses a significant environmental challenge. The improper disposal of tires contributes to landfill overcrowding, fire hazards, and habitat destruction. However, innovative tire recycling technology has emerged as a sustainable and eco-smart choice for addressing this issue. By converting used tires into ...

Catalytic Converter and How to Recycle It?
As it is known, the harm of cars, which make our lives easier, to people and nature is undeniable. Gases from exhausts cause serious damage to both human health and the environment. It causes air pollution. Catalytic converters have been used for approximately 45 years to largely block these gases released into the atmosphere.In catalytic converters connected to the exhaust outlet pipe of cars, ...

Soil and groundwater assessment, Northern England
Project Remediation Strategies were appointed to assist in the identification of a hydrocarbon contamination source that had resulted in significant vapours within a residential property. Further works to asses the nature and extent of soil contamination were also commissioned, together with detailed vapour risk assessments and subsequent vapour remediation works. Workspace An initial internal ...

Controlling Fugitive Emissions, Part 2: Permanent Total Enclosure
Fugitive emissions are the uncontrolled release of gases into the atmosphere. This is something that occurs regularly; in fact, it often happens when we fill our cars' gas tanks. The air being displaced inside the gas tank when it is being filled causes gasoline vapor emissions (hydrocarbons) to exit into the atmosphere in an uncontrolled manner. However, some states do require the use of ...

Asset management for actuated valves in the 21st Century
The key benefit of effective asset management for the actuated valve end user is an economic one. The implementation of preventative maintenance as the main activity in the asset management programme quickly translates into cost savings for the plant operator. This and many other benefits are facilitated and enhanced by the increased functionality inherent in modern intelligent electric valve ...

Ivey-Sol Technology has potential to increase oil recovery of oil-sands waste by 15-25 percent
Alberta’s oil sands are comprised of one of the world's largest sources of bitumen, containing an estimated 1.6 trillion barrels. About two tonnes of oil sands must be dug up and processed to produce one barrel of oil. Oil sands recovery processes include extraction and separation systems to remove bitumen from sand and water. Separating the oil from the sand is difficult and costly, and getting ...
