Abstract
Systems and methods for liquid removal to increase the accuracy of gas flow meters, such as venturi meters. Systems and methods include a liquid knockout drum, an impingement plate, a drum separator, and a check valve.
Claims10
A method for liquid removal to increase accuracy of gas flow meters, the method comprising the steps of:
- contacting a natural gas feedstream comprising wet gas with an impingement plate;
- separating liquids from the natural gas feedstream to produce a dry gas stream and aggregated liquids;
- collecting the aggregated liquids from the natural gas feedstream;
- measuring a flow rate of the dry gas stream, including the use of a venturi meter;
- pressurizing the collected aggregated liquids with a portion of the dry gas stream after measuring the dry gas stream, the portion of the dry gas stream expanding after measuring, where a first pressure of the portion of the dry gas stream after measuring is greater than a second pressure surrounding the collected aggregate liquids;
- and
- flowing the collected aggregated liquids and the portion of the dry gas stream to a common line.
