Flash Point Determination of Asphalt, Tar and Bitumen by use of Miniflash
Revolutionary Automated Distillation Analyser for Refining, Petrochemical Industries
PAC (USA) announces the shipment of their 1,000th OptiDist™, a truly revolutionary automated distillation analyser for the refining and petrochemical industries. Herzog’s OptiDist™ by PAC offers the highest level of precision and ease of use ever seen in an instrument of this type. It’s a state-of-the-art optimal solution for performing atmospheric distillation, featuring easy to use, one button operation, and unparalleled versatility. Its minimal footprint saves valuable lab space, installation is easy, and the OptiDist™ offers a very low cost of ownership.
Although the OptiDist™ was introduced to the market as recently as 2007, its popularity among users, due to its features, performance, and value, has made it a PAC ‘best-seller’, according to Eef Klok, Vice President, Laboratory Segment. “The OptiDist™ provides a unique, state-of-the-art fully automated D86 Distillation Analyser for our customers” Klok adds. “Herzog’s OptiDist™ is a patented optimiser and volume measuring system for fully automated distillation control that guarantees highest precision results, and is ideal for new fuels including ethanol blends and biodiesel blends.”
Measuring flashpoint of asphalt, bitumen or tar is a very rigorous test. Industrial coal tar pitch, for example; solid at ambient temperature, softens around 100-130°C and becomes fully liquid at 180°C. When cooled down, the tar sample becomes rock solid in seconds, making it difficult to clean flashpoint testing equipment and to continue with the measurements. The Miniflash flashpoint tester from Grabner Instruments (Austria) offers a solution to test even problematic coal tar pitch samples, with excellent repeatability.
Tar is used for a variety of industries, for example; aluminium production. Coal tar pitch is mixed with petroleum coke and baked at high temperatures to produce anodes and cathodes for smelting aluminium. Combustible coal tar pitch also poses a risk to the health of industry workers; if inhaled during the production process. When heated or incinerated, coal tar pitch produces hazardous odours. For safety reasons, it is therefore of critical importance to observe the flash point of tar samples. This is best done by testing flashpoint in a sealed cup without an open flame, using the least possible amount of sample, to ensure that no hazardous fumes are spreading.

The organisers of WWEM 2010, the world’s largest environmental monitoring event, have announced that this year’s event will include a dedicated Conference for the laboratory sector.
Focusing on efficiency, sustainability and acc - reditation, the Conference will address the key issues facing commercial laboratories in the new low-carbon, post-recession era and will be most relevant to analytical staff within the water, food/beverage, manufacturing, processing and environmental sectors.
With pressure on the costs of analytical services and demand from customers for faster results, efficiency has long been the key to success for laboratories. However, during 2009 improved efficiency provided a path to survival for commercial laboratories around the world and as countries emerge from recession the most efficient will be in the best position to prosper. The Lab Conference at WWEM 2010 will therefore examine ways to improve efficiency, particularly within the context of laboratory upgrade and new lab design.
Myriad standards, regulations and guidelines apply to analytical laboratories and the Lab Conference will examine the ways in which these can contribute to the overall success of a laboratory.
The UK government has pledged that emissions of greenhouse gases will be cut by 80% CO2 equivalent (measured against 1990 levels) by 2050. However, over the same period Britain’s population is expected to grow between 15% to 30%and it is likely that most industries will be required to meet higher quality and environmental standards – all driving up energy consumption. It follows, therefore, that all industries and their supply chains will be under pressure to reduce energy costs and contribute to the Government’s target.
Analytical laboratories have an important role to play in the achievement of sustainability objectives. Firstly by reducing the carbon footprint of their own activities, including the delivery of samples and results, and secondly through the provision of test data to inform operational decisions.
Taking place over two days (10th and 11th November) at the Telford International Centre (UK), the conference will be repeated on both days. Admission to the Lab Conference will cost £55/day or £100 for both days. Registered attendees will also have access to a parallel Conference at WWEM focusing on online monitoring and entitled: ’Water Monitoring in the 21st Century.’
WWEM 2010 will also include a programme of more than 70 Workshops and an international Exhibition featuring the majority of the world’s leading providers of test and monitoring instrumentation and services. Entry to the exhibition and workshops will be free (saving a daily admission fee of £20) to all pre-registered visitors, who will also be entitled to free onsite parking, free lunches and refreshments on both days of the event.

Specialist Karl Fischer titrator manufacturer, G.R. Scientific (UK), have launched the Aquamax KF Volumetric to complement their Aquamax KF moisture meter which is one of the most widely used coulometric titrators.
The new KF Volumetric offers several user programmes for titration and
standardisation. Incorporating two 5ml syringes, one can be used for the KF reagent and the other for automatic dosing of a standard for the titre. The second syringe can also be used for a different factor reagent or possibly special reagents for ketone / amine samples. There are two built-in peristaltic pumps, one for dispensing the solvent into the titration vessel and the other for emptying the vessel.
With many features including automatic rest cycle (stand-by mode) if not
used for 15 minutes, automatic air bubble elimination, intelligent control of drift value, connection to pc, printer, balances, etc. these titrators are also covered by a 5 year parts & labour warranty.
