Packaging offer: towards waste reduction

A large fleet of returnable packaging: drums, semi-bulk-containers (SBC) or iso-container is available. Bulk delivery is handled through trucks or iso containers.

The deliveries are performed usually in closed loop through dry break gas and liquid connections to prevent odorant leakages and odor smell around the injection stations.

Specific safety issue - Odor fade

Odorants are added as safety measure to prevent risks linked to a gas leak whether it is asphyxiation, fire, explosion, poisoning.

Be aware that the odorant chemical added to gas to make it detectable may not warn of a gas leak or the presence of gas to all persons in every situation.

Situations where the odorant in an odorized gas may be undetectable include:

  • Odor intensity may fade or be eliminated for a variety of chemical and physical causes, including the oxidation of odorant (mercaptans) on iron oxyde, adsorption onto the internal surface of pipes or appliances, or absorption into condensates.

Wide range of factors may influence such losses from gas quality to gas network construction material and process conditions (pressure, flowrate, temperature):

  • Contact with soil in case of underground leakages may de-odorize or remove odorant from the gas
  • Some people have a diminished ability, or inability to smell the stench of those odorants (anosmia). Factors that negatively affect a person’s sense of smell include age, gender, medical conditions, and alcohol/tobacco usage
  • The stench of odorized gas may not awaken sleeping persons
  • Other odors may mask or hide the stench. ( unusual impurity profiles from biogas or shale gas)
  • Olfactory adaptation or olfactory fatigue, when the exposure to the odorant lasts and person gets used to this level of intensity.

Gas detectors can be used as an extra measure of safety for detecting gas leaks, especially under conditions where the odorant alone may not provide an adequate warning. Gas detectors emit a loud, shrill sound when gas is present and do not depend on sense of smell.
