Assentech – Keeping the Industry Safe, Compliant & Profitable

Reducing fugitive emissions and documenting the process will be music to the ears of your Compliance Team who are likely getting to grips with ESG declaration as we all adapt for the challenge of meeting net-zero.

If you store bulk liquid on site in low pressure or atmospheric tanks you are likely to be well acquainted with tank breather vents. Something that is widely unknown is that there is a functional performance standard for these devices. This standard benchmarks the vent’s ability to keep the tank normally closed to the atmosphere when liquid levels and temperatures are stable, which accounts for over 90% of the time.

As we are entering a new era where public consciousness of air quality is increasing, Assentech hope to bring the importance of breather vent performance and maintenance to light because these are a major player in reducing fugitive emissions, however are currently overlooked in the industry.

PVRVs or Tank Breather Vents are categorised as critical safety components.   If not properly set, calibrated and serviced, they could be costing you thousands of pounds in leakage, negatively impacting the environment and exposing your workforce and the public to harmful media.  In severe cases, poor tank farm management can result in tank collapse or explosion with catastrophic consequences.

All of the unnecessary vapour losses can be easily eradicated by using informed procurement of new equipment and the use of best available techniques in maintenance of ageing plant.  Assentech can support you at any stage using 25 years’ experience, whilst following industry best practice and using equipment that meets international standards.

By understanding that there needs to be more support around procurement and maintenance of breather vents, this led them to design and develop a patented range of fully automatic Vent-Less test benches, which are the first of their kind worldwide. The device automatically runs through a set point and leakage test procedure, aligned to the test criteria of API2000 and ISO28300, using calibrated flow controllers and pressure sensors.  The test takes a maximum of 3 minutes displaying performance flow-curves during the test before an instantaneous functional test certificate is generated.  The test data provides an independent assessment, where the technician has no opportunity to influence the results. This is vital where a negative test result could lead to a replacement device being required.   The Vent-Less test bench demonstrates operator due diligence.

The procedure can be viewed remotely as part of a witness test if required and a detailed certificate with vent serial number, setting and full functional performance graph is produced. This can also be shared using the QR code on the front of the test report.

Assentech is the only breather vent maintenance company in the UK to test so comprehensively using our written scheme of examination and our own patented, fully automated test equipment.
