Abstract: The present invention is related to the application of terpolymers based on alkyl acrylates as defoamers of gasified crude oils, with densities between 10 and 40° API. The evaluation of terpolymers based on alkyl acrylates at conditions similar to those of gas-liquid separators has shown that the terpolymers are efficient as inhibitors of the foam formation in heavy and super-heavy crude oil, abating the foam between 15 and 50% faster than in non-dosed crude oil (blank). Even some acrylic terpolymers exhibited a greater efficiency as defoamers than that of commercial silicon-based polymers, which promoting the defoaming only 20-25% faster than the blank collapse. The employ of silicones as defoamers presents serious problems as the formation of deposits and the deactivation of catalysts in the refining processes. This situation has provoked that refineries in Mexico and a worldwide ban the application of this kind of inorganic polymers, and new silicon-free defoaming agents are required.

Abstract: The present invention is a solid lubricant treatment medium, usually but not always in bead form, suitable to be brought into contact with lubricants to remediate and to condition them. A key feature of the medium, typically a polymeric resin, is the presence of relatively very large pores, which are able to capture and remove fine lubricant contaminants and breakdown products (such as small phosphate ester varnish, soot, coke, dissolved metal or other small semi-soluble or insoluble particles). Resins and adsorbents of the prior art have proven unable to remove fine contaminants like phosphate ester varnish that have a deleterious impact on industrial equipment performance and reliability. The mean pore size diameter of the medium is between about 8,000 ? and 100,000 ? and, more preferably, in the range of about 20,000 ? to about 80,000 ?.
