42 Measurement and Testing A New Appraoch to Odour Monitoring


Several years ago, Chromatotec developed a new solution to measure levels of the intensity of odour variation called the vigi e-nose. The name of this product was used to compete with other electronic noses (e-noses). E-noses offer a good alternative to dynamic olfactometry measurement to check odour intensity variation. Most of the existing e-noses in the market deploy detection sensors known as Metal Oxide Sensors (MOS).


These technologies provide a global fingerprint using two main principles of detection: non selectivity and cross-interference with humid sensitivity. Some providers try to integrate ‘specific sensors’ such as NH3 or H2S but these sensors are sensitive at ppm levels and cannot reach human nose sensitivity. However, these solutions allow tracking gas variations with additive information in spite of the fact that sensors used are crossed-selective (for example, a non-selective H2S specific sensor is prone to interferences with Mercaptans and ammonia)


Raw data coming from the analysers is calculated and collated by mathematical models using artificial networks or multivariate statistics. This provides results correlated with a reference odour sensory method (as dynamic olfactometry if used according to European standard EN 13725 or ASTM 679 E-4 if US standard is required).


Due to customer non satisfaction with their existing solutions, Chromatotec has developed and deployed their solution initially in municipal Waste Water Treatment Plants in France, UAE and Poland and more recently in sites equipped previously by competitors’ e-noses. Tests were carried out comparing the vigi e-nose favourably with the exisiting e-noses. The revolutionary approach is based on the separation of 14 sulphur compounds, such as H2S, Mercaptans, and Sulphides also including VOC concentration with an all-in-one solution. This turn-key solution offers the capability to reach concentration levels lower than the human nose can detect.


When odour impact measurement is needed, theChromatotec’s latest development of dispersion software development (vigi Odor) allows operators to integrate with standard atmospheric systems such as AERMOD, which is recognised by the USEPA.


Saudi Aramco Selects Ballast Water Testing Device


For More Info, email: email:


Oil producer Saudi Aramco has selected Chelsea Technologies Group (CTG), designer and manufacturer of sensors for the maritime sector, to provide benchmark testing for compliance with ballast water standards. This follows Saudi Aramco’s announcement that all ships calling at its ports and terminals will be required to provide ballast water samples, in order to demonstrate compliance with the International Maritime Organization’s Ballast Water Management Convention.

CTG’s FastBallast portable ballast water analyzer has been chosen by Saudi Aramco and will be deployed as a benchmark testing device to conduct spot checks on indicative sampling undertaken by third-party sampling companies. FastBallast was selected following a detailed technical review conducted by Saudi Aramco’s in-house marine biology experts.


Together with Global Strategic Alliance Saudi Arabia (GSA), its agent for Saudi Arabia and Bahrain, CTG has also provided consultancy and guidance to Saudi Aramco’s in-house experts on the testing and sampling standards and processes that should be put in place to ensure compliance with IMO standards. In addition, GSA is working closely with the Saudi Arabia authorities to utilize FastBallast as the national benchmark for indicative ballast water sampling.


Dr Brian Phillips, Managing Director of Chelsea Technologies, commented, “It is testament to the confidence of Saudi Aramco in the unrivalled accuracy and reliability of FastBallast that it has been selected as the gold standard for ballast water sampling in ensuring compliance with the IMO Ballast Water Management Convention. Together with GSA, our sole agent in Saudi Arabia and Bahrain, we look forward to working together with Saudi Aramco to ensure that all third-party ballast water sampling meets the high standards of compliance now required of all vessels calling at Saudi Aramco ports and terminals from international waters. We are proud of the role that FastBallast will play in creating the national benchmark for ballast water sampling and, in doing so, helping to protect Saudi Arabia’s marine environment.”


Saudi Aramco ports and terminals are considered the highest receiver of ballast water from ships, with over 180 million tons of ballast water discharged during cargo operations every year.


Saudi Arabia ratified IMO’s Ballast Water Management Convention during April 2017, through a Royal Decree signed by the Custodian of the Two Holy Mosques King Salman bin Abdulaziz, activating the adoption of a national ballast water management strategy, which includes indicative sampling of ballast water.


Global Strategic Alliance Saudi Arabia (GSA), CTG’s sole agent in Saudi Arabia and Bahrain, was invited by Saudi Aramco to participate in a workshop held in Saudi Aramco headquarters in Dhahran on 26th July 2017. The workshop was held to facilitate the launch of ballast water indicative sampling at all Saudi Aramco ports and terminals and was attended by GSA’s CEO, Adnan Bahamdein, and GSA’s Operations Director, Ramachandran Kumar.


GSA is also working closely with CTG to make its FastBallast onboard indicative ballast sampling devices available to ship owners and operators throughout Saudi Arabia and other GCC (Gulf Cooperation Council) countries.
