#77 - Sample Preparation for Corrosive Gases

Exhaust gas analysis is frequently required for incinerators and other combustion processes that produce corrosive waste gases such as SO2 and HCl.

Some gases are inherently corrosive while others are soluble and can produce acids when dissolved in condensate that is formed as gases cool. If these gases do not require analysis, the best approach is to remove them before analysis.

Ideally, the sampling system in these cases should be designed to continuously extract, filter, and scrub the flue gas before it goes to the gas analyzer.

Our preferred approach is to filter the gas at the sample point while it is still hot. This ensures that the particulate is removed prior to formation of condensate. After that, condensate formation may occur freely without risk of creating a particulate slurry and plugging the sample lines.

The 7240 / 7300 Series Systems have been designed for this purpose. The sample gases are drawn into the high temp probe and continue on into the heated particulate filter. Next, they travel to the water wash system where they are cooled and scrubbed of corrosives. They are then sent to the gas analyzer cabinet for final analysis.

FEATURES

• Economical and reliable sample gas cleaning system
• Allows analysis of acidic flue gases
• Can be used on samples with high particulate
• Only small amount of 'make-up' water required

We have used these systems on medical waste incinerators, municipal waste gasifiers, and other processes that produce corrosive or aggressive gases.

For information on these and other gas analyzer systems, give Mike or Dave at Nova a call, or send us an e-mail.

#76 - Live Security Platinum Virus

My home computer was recently infected with a nasty virus called Live Security Platinum. This particular virus is carried into and installs on a computer via a Trojan horse virus. It seems to have loaded onto my computer while I was downloading a graphics pattern for a construction diagram that I was producing.

This rotten malware takes control of the computer and poses itself as an anti-virus program. It flashes the usual fake warnings about dangerous virus and malware infections. To be saved, all you have to do is purchase a key code. The ‘program’ will then remove all of the ‘infections’.

The particularly annoying thing about this virus is that it prevents many other programs from starting. It may also block internet links, claiming that they are not trustworthy. The Remove Program function in Windows Control Panel also does not seem to work.

Fixing the problem requires consulting the internet using another computer that is not infected.

Some websites have posted the activation key for this fake antivirus ‘program’.

I forget which key I used. This key doesn’t actually remove the virus, but it does cause it to settle down a little and allow other programs to work.

To remove the virus, I used a free program called Chameleon by Malwarebytes. It worked quite well. It even resolved some other issues possibly caused by other viruses on the system.

This virus annoyed me because interfered with productivity and caused me to miss a minor deadline on a task. Thankfully, the fix was fairly simple and conclusive. There was a satisfying irony to using its own activation code to help deactivate and ultimately remove it.

Happy surfing!

#70 - Post #5 is our most popular blog post (Syngas and Gasification)

The folks at GEK Gasifiers have a nice introduction to this process.

http://gekgasifier.com/gasification-basics/

This is not a new concept. It has been around for many years. 

Gasification and vehicles have long traveled together.

One great thing about this idea is that is very scalable. You can build a small gasifier out of a soup can. There are also mid-range gasifiers that can be thought of as ‘garage-scale’. And there are large industrial plant-scale gasifiers.

Gasification can serve as an intermediate step between many types of feedstocks and many other production processes as the chart below demonstrates.

Each of the processes mentioned in the chart above require a gas input of a specific makeup. This is why an analyzer system is frequently required between the output of the gasifier plant and the input of the receiving process.

We are frequently approached by manufacturers and educational institutions also. The end-users may be researching and developing a new gasifier design. Or they may be tuning a gasifier system for optimum performance and gas production. Having a reliable gas analyzer to measure oxygen / carbon monoxide / carbon dioxide / hydrogen / methane is an important part of this process.

The Nova 970 Series Syngas and Gasification Analyzers have been specifically designed with this application in mind. The gas that comes out of a gasifier frequently has conditions and constituents that are detrimental to an analytical instrument. Because of this reality, we have produced an instrument that is industrially hardened and user-friendly.

1. Process pipe  2. Probe and Filter  3. 970 Gas Analyzer
4.  Wire Connections available to customer

The materials of construction and the straight-forward layout of this instrument gives us a great deal of confidence in recommending it to our customers. If you have a gasifier and need analysis of your produced gas, think about buying a Nova. We have bench top configurations for temporary or intermittent analysis. We have wall–mount configurations for permanent continuous analysis.

For information on these and other gas analyzer systems, give Mike or Dave at Nova a call, or send us an e-mail.

#66 - Delkor – Liquid Handling Experts

Separation of liquids and solids is important for many reasons. Two obvious ones are to extract a wanted or un-wanted solid, or to clarify a liquid (often water). Liquid / solid separation is a key component of waste water treatment plants and ore extraction plants.

Not all solids and liquids separate easily. Particle size, geometry, electrical charge, and other factors may keep the solids uniformly distributed throughout a liquid phase. Various techniques, chemicals, and equipment may be employed to counteract these effects.

Delkor is a diverse solutions-based equipment supply company in the Solid / Liquid Separation field which is grouped under Delkor Technik B.V, a wholly owned subsidiary of Tenova S.p.A
www.tenovagroup.com

Delkor is the leading supplier in the Solid / Liquid Separation field and has built a reputation for the supply of quality engineered products to their client base in the minerals, chemical and industrial markets.

#65 - Experts

What does it take to be an expert on something?

My handy on-screen dictionary says that an expert is ‘a person who is very skillful or highly trained and informed in some special field.’ The word ‘expert’ is linguistically linked with the word ‘experience’, which makes sense. One becomes an expert partly through experience.

Strangely though, the word also draws its root from a Latin term for danger or risk. I suppose the idea is that any new experience carries with it some degree of risk. That risk may be physical danger, failure to succeed, failure to comprehend, personal dislike, or some other outcome that we may define as potentially negative.

Whether we succeed or fail, some useful experience will be gained, although we can reasonably assume that ‘expert’ is usually more closely associated with successful experience.

In your experience, you may have noticed varying degrees of expertness in people, or different types of ‘expert.’ We will discuss some of these in the next post.

Here at Nova, we have gained some expertise in gas analysis over the years. Some of it has been through failure, and much of it has been through success. Some of it has come from books, but much of it has come from talking and working with other helpful people.

Nova website “About us…”

We make gas analyzers for oxygen, hydrogen, carbon monoxide, carbon dioxide, methane, and many other atmospheric gases. We provide gas analysers for syngas, landfill gas, purity gas, biogas, and others.

#64 - Tenova Lands on South Korean Shores by Acquiring Envita

Milan, April 6th 2012 – Tenova's growth strategy continues with the acquisition of Envita Co. Ltd. The South Korean company, founded in 1995 and with headquarters in Incheon (near Seoul), is active in the fields of industrial furnaces, processing lines, and heat treatment furnaces for aluminum components in the automotive industry. Its people, over 100, are operating in three locations in South Korea, Vietnam (Ho Chi Minh City), and China (Yantai).

The company is well known to Tenova, who began working with Envita in 2007. Thanks to the collaboration with Envita, Tenova has been awarded contracts in the country with major steelmakers such as Hyundai Steel and Posco.

The acquisition marks Tenova's first step into South Korea, the 6th highest crude steel producer in the world with 68.6Mt in 2011. This is a +16.2% increase over 2010. South Korea has the highest density per capita production of steel in the world: a strategic market in the global post-crisis scenario.

The Tenova Iron & Steel division achieves the goal of entering South Korea through an engineering hub with excellent references and manufacturing centers. The combination of these factors allows the expansion of our commercial and operating network in Asian countries such as Vietnam, Thailand, Indonesia, Malaysia, Philippines, Singapore, Laos, and Cambodia. It also provides an expansion of the Tenova Iron & Steel product portfolio in the business of cold rolling and aluminum for the automotive industry.

Tenova is a worldwide supplier of advanced technologies, products, and services for the iron & steel and mining industries. With about 3,100 people, Tenova operates through more than 30 companies located in 22 countries on 5 continents.
