Gas Analysis at the Refinery

14 Jun 2016

In this application note, Beatriz Sales Sebastiá, a chemist in the laboratory of the BP refinery, reports on water content determination in gases. Beatriz Sales Sebastiá is responsible for liquefied petroleum gas analysis, including the measurement of water content as water influences the activity of some catalytic converters and causes pipes and reactors to rust.

901 Titrando for Karl Fischer Titration

Metrohm AG

901 Titrando - The Karl Fischer Titrando for the modern titration laboratory Thanks to its modular concept the Titrando System can be optimally adapted to any application. It meets the requirements of FDA Regulation 21 CFR Part 11. Profit from its intelligence and multiple communication options (USB, RS 232C, Remote)!In addition to the Karl Fischer mode (KFT), this high-end titrator also includes the SET mode, which means that titrations can be carried out to a predefined endpoint. "ITrode ready": The high-resolution, galvanically separated measuring interface - now also with additional digital measuring input for intelligent electrodes «iTrodes» - means that it is also possible to make high-precision pH measurements Transparent operation – thanks to specially adapted dialogs, the Titrando accelerates method development and simplifies routine operation. The large color screen of the Touch Control informs you about the instrument condition and offers uniquely comfortable operator guidance. For operation via a PC the appearance is exactly the same. Numerous worked-out methods and titration examples make familiarization easier. Method templates and calculation formula templates are available for developing your own methods. Extended titration and evaluation parameters open up new applications. More intelligence: The Data Chip of the Dosing Unit contains all important titrant data. Thanks to the sophisticated Liquid Handling, automatic reagent exchange is now also possible in volumetric KF titration. The 901 Titrando works with Dosing Units, which are ideal for handling KF reagents. Parallel titration – a Titrando can work with two titration cells at the same time (requires tiamo).

Gas Generators and AnalyzersGas generators are used for supplying or monitoring a regular flow of a high purity gas such as nitrogen, hydrogen or zero air for applications such as gas chromatography. Gas analyzers can be used in supply chain processes and laboratory experiments with portable analyzers for monitoring CO<sub>2</sub> and O<sub>2</sub> levels as well as trace gases. Regular flow can be produced with gas control modules and flow meters.
