US scientists have developed improved coatings for the inside surface of oil and gas lines to reduce the likelihood of hydrates sticking to them and restricting the flow. The new coating is made from a combination of titanium dioxide (TiO2) and zinc oxide (ZnO), which are both used in many industrial applications. In tests, the coating showed good results in preventing hydrates sticking to the surfaces.
US scientists have developed improved coatings for the inside surface of oil and gas lines to reduce the likelihood of hydrates sticking to them and restricting the flow. The researchers from the Colorado School of Mines created a composite polymer coating that was designed to be applied to previously worn and corroded surfaces, and a second coating created with the addition of nonpolar nanomaterials. In tests, the coating showed good results in preventing hydrates sticking to the surfaces.
