  • Patent number: 11090234
    Abstract: Provided is a product exhibiting good bubbles even from a screen foamer composition using a non-ionic surfactant. This foam contains a non-ionic surfactant and is composed of an air layer and a bubble shell encapsulating the air layer. The bubble shell has a high light transmission region which is optically transparent and a low light transmission region which is less optically transparent than the highlight transmission region, both regions being disposed so as to spread across a surface of the bubble shell in such a manner as to form an identifiable boundary therebetween; and when the foam is allowed to stand at 25° C., an area of the low light transmission region occupying the surface area of the bubble shell expands over time, and thus the entire surface of the bubble shell becomes occupied by the low light transmission region.

  • Patent number: 10975185
    Abstract: Nowadays, one of the major problems of the oil industry is the presence of large amounts of water and salts, which cannot be efficiently removed by conventional dehydrating polymers. In addition, the acid stimulation operations of petroleum wells cause the chemical degradation of demulsifiers such as polyethers and phenolic resins, reducing drastically their efficiency as water and salt removers. Based on aforementioned, a series of new copolymers has been developed; these copolymers are combinations of an acrylic and an aminoacrylic monomer and they are synthesized by semi-continuous emulsion polymerization (under starved feed conditions), which ensures both the homogeneity of the different chains as well as the randomness of the monomers distribution. The solutions of one of these random copolymers have shown an efficiency similar or superior to combinations of two or three block copolymers (formulations), when they are applied in light or heavy crude oils.

  • Patent number: 10919772
    Abstract: The present invention relates to a method of preparing a hydrophobic metal oxide-silica composite aerogel, in which a degree of hydrophobicity may be controlled while having a high specific surface area and a low tap density, and a hydrophobic metal oxide-silica composite aerogel prepared thereby. The preparation method according to the present invention may not only have excellent productivity and economic efficiency due to a relatively simpler preparation process and shorter preparation time than the related art, but may also perform an effective surface modification reaction by using a small amount of a surface modifier. Thus, since the surface modification reaction may be easily performed by using only a very small amount of the surface modifier, a hydrophobic metal oxide-silica composite aerogel containing about 1 wt % to 2 wt % of carbon may be prepared.
