Since they are condensable (may be referred to as condensates) they often form in natural gas wells when the pressure begins to lessen. Cryogenic separation is a processing operation that is commonly used to extract natural gas liquids (NGLs) from raw natural gas. Refineries are a secondary source of some NGLs. The next logical step is NGL (Natural Gas Liquids) extraction and fractionation. Primary separation consists of a screen that the natural gas liquids pass through to remove any particulates that are in the liquid. Published December 2016. Missed an event or webinar? Unlike absorption methods, which are used primarily for extracting heavier NGLs, cryogenic processes are used to separate out lighter hydrocarbons such as ethane, propane, and butane from an incoming stream. Natural gas liquids (NGLs) are hydrocarbons—in the same family of molecules as natural gas and crude oil, composed exclusively of carbon and hydrogen. US demand for NGLs has lagged behind supply growth, but will significantly increase when ethane steam crackers now under construction or planned for start-up come online. It can be used for separating solid particles from liquids, or for separating non-miscible liquids. 10 Refrigeration in natural gas treating is a process and/or series of processes that involve 11 separation of natural gas liquids (NGL) from the raw natural gas. The separation specifications are allowable liquid of up to 0.1 gal/MMscf in separated gas, and allowable free gas of up to 2% v/v in separated oil.
