What Humidity Challenges do Engineers Face?

When designing medical equipment, engineers can often feel like Goldilocks when it comes to humidity: there’s too much or too little—and their challenge is to make it just right. Too Much Humidity is a Frequent Problem The air (or a gas) can only hold so much water vapor. Depending on external factors like temperature and pressure, water vapor can condense and create lot of ...

Quick laboratory analysis of gas condensate in produced water

Abstract Often there is a need for quick field measurement of gas condensate concentration in produced water, such as when performing process optimization, water treatment verification and routine process monitoring. Rigorous laboratory analysis methods such as gravimetric oil and grease measurements or gas chromatographic methods are not sufficiently sensitive to process changes and/or do not ...

Reducing the Likelihood of fluid hammers in steam applications

Many of us have heard the sound of pipes banging as we turn a faucet on or off. This sound is the water in the pipe being forced to stop or suddenly change direction and is called “water hammer.” Did you know that water hammer is not just limited to water pipes? In fact, water hammer, more generally called “fluid hammer” or “hydraulic shock,” is possible ...

Exploring US EPA Method 524 Purge and Trap Variables: Water Vapor Reduction and Minimizing Cycle Time

Introduction Purge and Trap (P&T) concentrators have been used extensively for the analysis of Volatile Organic Compounds (VOCs) in water since the mid 1970’s. By passing a purge gas through the sample, VOCs are swept to an adsorbent analytical trap on which they are collected. The trapped compounds are then released through thermal desorption, separated by gas chromatography, and then ...

Real Time TOC Analysis in Steam and Condensate

Executive Summary Steam in petro/chemical plants could be contaminated with hydrocarbons (TOC = Total Organic Carbons) from various sources. In any case this is a sign for defects in the process, whether it they occur in the heat exchanger, the blow down vessel, the condensate recovery or other parts of the system. Conventional solutions to monitor such contaminations use TOC- analyzers that ...

Checklist for Boiler Maintenance

Boilers play a crucial role at industrial facilities and it is imperative that they be safely and properly maintained. Routine boiler maintenance can help prevent unplanned shutdowns and outages, increase the efficiency of the boiler and cut operating costs, and ensure that the facility is in full compliance with all laws and regulations governing boiler safety. What follows is a boiler ...

Legionnaires is an Air Quality Risk

The recent Bronx, NY outbreak of Legionnaires infections is a grim reminder of the deadliness of this strain of pneumonia. Like many of the outbreaks, cooling towers caused this one. Twenty have been identified but the search is still going on. Over 120 people were infected and 12 have died. Tragically it affects the most vulnerable people–people with one or more immune system deficiencies. ...

Catalyst-Based Non-Chemical Water Treatment

Catalyst-Based Device Reduces Calcite Buildup, Requires Minimal Maintenance According to the US Geological Survey, more than 85 percent of the United States has hard water.1 In plumbing, hard water leaves calcite deposits that restrict water flow by occluding pipes. In water heaters, calcite coats heating elements, causing them to overheat and eventually fail. Standard approaches to calcite ...

Condensate-free debinding with vacuum furnaces

Today techniques like pressing, rapid prototyping, powder metallurgy, siliconization and sintering are widely used production methods. Sintering, for example, is only the last step of a near-net-shape fabrication technology. Many processes, such as metal injection molding (MIM) for example, require a debinding step prior to the actual sintering. For metal injection molding a small part of a ...

Reducing Mercury Impacts in Small-Scale Gold Mining

Despite knowing full well the dangers of mercury, millions of small-scale gold miners across the globe continue to use the metal to separate gold from ore - usually because they have little other choice. The mercury is mixed into ore and combines with the gold in a compound that can easily be scooped out and squeezed into a small bar of amalgam. This is then burned so that the mercury ...

Self–organisation of regular dusty structures in plasma trap

The formation of ordered dusty structures in the special RF–gas discharge (plasma trap) capable of capturing and confining nano– and micro–particles in electromagnetic field was studied experimentally. Two ways of the dust–plasma structure formation were investigated: (1) The condensation of preliminary evaporated organic or inorganic substances. The plasma trap could confine the vapour clusters ...
