When working with any type of gas, it is important that you know how to store them. LPG is shorthand for liquefied petroleum gas, and it may be refined in the same place or even at the same time that crude oil is extracted. NGL stands for natural gas liquid, which is natural gas that has been turned into a liquid form. What are some of the differences in how they are stored?
LPG Is Generally Stored in Smaller Containers
In less developed countries, LPG is used as a cooking fuel. You may also be able to buy small containers of it at the grocery store or at camping stores, and you probably know it better as propane. While propane is used because it is easier to condense and store at relatively low pressures, it is important to guard against leaks. In many cases, compounds are included in the bottle or container that release an odor if there is a propane leak. This makes it easier to detect when one occurs and take proper safety precautions.
NGL Is Generally Stored In Cold Tanks
Although NGL is natural gas, it is not the same natural gas that you would use to heat your home or heat a building. Instead, it is used in oil production and other similar industrial endeavors. As a liquid, it must be stored at temperatures as low as minus 165 degrees Celsius.
Both Gasses Are Liquid When Stored
Anyone who uses or purchases LPG or NGL should know that they are in liquid form if they are being stored and turned into a gas when used. When either material is extracted and liquefied, care should be taken to get rid of any impurities that may exist such as sulfur or excess water as they could make cooling or storing it dangerous. In the event that a company is buying NGL, they will need to have a plant capable of treating the liquid material as it is being turned back into a gaseous state.
Whenever you deal with gasses whether they are gas or liquid form, it is critical that steps are taken to properly handle them. Warnings should be put on all containers in both text and picture form. If a container is not properly labeled, consumers should do whatever they can to do so. This may prevent a child from ingesting it or otherwise mishandling it inadvertently or prevent a worker from doing the same in a lab or on a factory floor.
