AI Technical Summary
Technical Problem
Existing negative pressure gas extraction methods are difficult to separate water and gas, and are not suitable for small-scale operations, resulting in serious waste of resources.
Method used
A wellhead gas negative pressure collection device was designed, which includes a drying and filtration zone and a water separation and filtration zone. It adopts a vacuum pump and a packing layer structure. The vacuum pump draws in gas, and the packing layer is used to separate water and gas and clean impurities.
Benefits of technology
