Gas Odorization
40 Years of Experience Make LEWA Number One
Customers all over the world have been putting their trust in LEWA systems for more than 40 years when it comes to odorizing gas. Our portfolio of solutions for this application ranges from systems for micro-metering through to gas pressure regulation stations.
Scores of suppliers also put their trust in LEWA systems for odorizing LPG and CNG in the complete transport chain, as well as in gas stations and filling stations. Another large area of application for our systems is liquefied natural gas (LNG) in import/export terminals before distribution. And last but not least, LEWA odorizing systems are also used for odorizing oxygen and technical gases.
We plan and produce systems based on your specifications and, of course, equip them with LEWA core components: Pumps, flow meters, and a control system (closed control loop). Our systems use quantity-based odorization, controlled by the gas flow (injection process).
Areas of Application in Gas Odorization
LEWA odorizing systems allow you to add many different odorants to gases. This includes natural gas (1 bar to 300 bar), biogas (1 bar to 300 bar), LPG, oxygen, nitrogen, carbon dioxide, hydrogen, LNG, as well as unconventional gases.
