Don’t let your money go up into the ear: Each year, huge ammounts of LNG are lost as vapors due to pump or compressor technology limitations. But there is a chance to do better…
Imagine you were creating a refining, transportation, delivery and storage network today for a newly discovered petroleum product. Its characteristics include an ability to be shipped and stored in pressurized containers as both a liquid and gas. Because of these characteristics, however, the delivery network has a few inefficiencies that just can’t be overcome, including:
From it’s extraction and processing at the refinery, to tank or truck transfers, or to the maintenance on small twenty pound storage cylinders, a small amount of saleable vapor either escapes or is, by necessity, burned off into the atmosphere.
When receiving delivery of the product from a large tank such as a 33,000-gallon rail car, the end-user may be expecting to receive close to 30,000 gallons, for example. However, because pumps are unable to completely empty 100% of the liquid from the tank or remove vapors, as many as 1,000 gallons of liquid are left behind in the form of un-recovered vapors.
Confronted with these conditions, no right-thinking person would make an investment in this new petroleum product. Of course, this product – liquefied petroleum gas, or LPG –has been a vital fuel around the world for nearly a century, despite the inefficiencies inherent in its storage, transportation, handling and delivery.
But with LPG’s price increasing, along with possible increased attention from the United States’ Environmental Protection Agency (EPA), these inefficiencies can no longer be tolerated. With so many points in the LPG supply chain, there are still millions of gallons of recoverable, useable and sellable vapors literally going up in smoke every year.Blackmer
