👉 A U-Screw is a type of high-pressure, low-volume system that is commonly used in the industrial process for the separation and concentration of crude oil. It works by compressing the oil through a series of chambers to increase its pressure and volume, allowing it to be separated from other materials. The U-Screw is typically used as an auxiliary unit in a refinery or petrochemical plant, where it is used to separate crude oil into different grades based on their viscosity and density.
