Natural gas separators remove solid particles and liquids from a continuous gas stream supply. Dust, dirt, sand and pipe scale as well as water, natural gas liquids and light hydrocarbons can be removed. Removing these substances from the natural gas supply creates a more refined product and protects downstream process equipment from malfunctioning.
Magnetrol® has produced an applications brochure for the power industry, detailing measurement challenges and solutions for each step of the power generation process. This blog post is part of an occasional series exploring each application in detail.
Level Measurement Challenges and Considerations
In a typical system, an inlet separator allows particles and liquids to settle out and the gas to rise. The gas collects at the top of the separator where it is removed by means of a gas compressor. The collected particles and liquids are then dumped into a water tank. The amount of water that is drawn off needs to be precisely modulated. If the level rises too high, the liquid will enter the compressor inlet. Liquid level measurement instrumentation can monitor the water level and prevent it from entering the inlet.
