Coalescing Filter Sizing using Rated and Specified Pressure Loss Components

Updated

In the oil and gas industry, Flownex is often used to build complex gas flow networks with the purpose of determining pressures, temperatures and velocities at any point and pressure losses of certain components or groups of components as well as the system as a whole.

As such, situations often arise where the pressure loss of a component or network area is known at certain conditions (at a certain flow, a certain pressure and a certain temperature for a certain gas) but calculations have to be performed at other conditions. It is for this specific purpose that the Rated Pressure Loss component was developed and is presented in this case study.

A typical application of the Rated Pressure Loss component is a gas coalescing filter, which serves the purpose of removing solids and liquids from the gas, and as such will become increasingly fouled, resulting in increasing pressure losses. The operational lifecycle of such a coalescing filter is more complicated than it may at first appear and is presented and discussed in this case study. Coalescing filters also serve to remove liquids from the gas flow; however the details of the liquid removal process is outside of the scope of this case study and is not considered in detail.

Similarly, the user often wants to specify a constant pressure loss for a component or area, typically during the design phase when pressure loss quotas are allocated to specific components or areas. The Specified Pressure Loss component was developed for this purpose and is also presented in this case study.
