High safety level of gas monitoring!

 

The task of mineral oil logistics is the reliable distribution of combustible substances from the producer to the end consumer. These are mainly:

  • petrol and diesel fuels
  • kerosene
  • fuel oils
  • methanol
  • benzene

Distribution can take place directly ex refinery or via an intermediate tank farm using tank trucks.

When tank farms are used, a high safety level of gas monitoring is required.

To meet the SIL requirements, the MSR-Electronic product PolyXeta2 with the innovative exchangeable X-Change sensor is employed detecting volatile organic hydrocarbons due to the reliable safety calibration of the sensor.

Wherever flammable or toxic gases are present, the risk potential for people is particularly high, as they often cannot be smelled or seen. Fixed gas warning systems significantly reduce these risks for people and plants.

With innovative products, MSR-Electronic reliably protects lives and values against dangerous gases. The international company successfully sells products of gas warning systems via branch offices and partners worldwide.

The newly developed Bremen tank storage area requires a solid safety concept meeting the strict safety requirements from the authorities.

 

 

Measuring method

 

The measuring method with integrated temperature and drift compensation stands for highest accuracy and reliability with the long service life of the sensor.

The device has a standard 4-20 mA analog output and two relays with adjustable switching thresholds. In the emergency of a leakage, an early warning of the occurrence of an ignitable gas concentration and countermeasures can be initiated.

Installation and maintenance of the PolyXeta2 series are carried out by the MSR partner Gawado Gaswarnsysteme in this project. Regular functional and system checks in accordance with BG RCI T023 ensure the reliability of the gas monitoring system and the compliance with the requirements.

 

The explosion range

 

Combustible gases form explosive mixtures in combination with air. There is only a limited range of gas/air concentration in which an explosive mixture occurs.

An important core size for the hazard is the explosive range - the space between LEL and UEL. This area, which is defined by an upper explosive limit (UEL) and a lower explosive limit (LEL), is specific for each gas and each vapour.

Outside these limits, the mixture is not flammable. Each gas reacts differently and therefore has different limits.

In the past, these properties of combustible gases have led to sometimes large fires. In North Rhine-Westphalia, for example, there was an expansive tank farm fire in Duisburg harbour in 1979. However, the fire at the Buncefield tank farm in Great Britain in December 2005, which lasted for several days, was even more devastating.

MSR-Electronic is a manufacturer of fixed gas warning systems with decades of experience in the field of building automation and gas measurement technology.
The international company with headquarters in Germany has a wide range of methods for the detection of toxic and combustible gases. On this basis MSR-Electronic develops individual gas sensors, controllers and warning devices for many applications, such as parking garages, tunnels, petrochemical industry or shipping. The products meet more than the general standards and regulations and can therefore guarantee the safety of the plant. If you have any questions please send us an email or give us a call.
