Abstract: A method for mitigating fouling in a once-through steam generator train is described. The method involves obtaining foulant samples from the once-through steam generator train. Obtaining water samples from one or more locations along the once-through steam generator train. Recovering filtered solids from the water samples from the one or more locations. Characterizing at least one physical property of the foulant samples and the filtered solids. Determining locations along the once-through steam generator train that include foulant precursor based on a matching of the at least one physical property between the foulant samples and the filtered solids. Installing an absorbent at locations that include the foulant precursor.

Abstract: Systems and methods generate steam from produced water by passing the produced water through first and second steam generators coupled together. The first steam generator produces wet steam in which a liquid effluent with impurities of the produced water passes to the second steam generator. The second steam generator combusts fuel and oxidant in direct contact with the liquid effluent. The first and second steam generators limit fouling and waste while providing a combined steam output that may include combustion products from only the second steam generator.

Abstract: Method and systems relate to generating steam by transitioning water from supercritical conditions and injecting the steam that results into a formation to facilitate recovery of oil. Pressurizing and heating the water forms a supercritical fluid that may solvate impurities in the water and/or oxidize the impurities. Retaining the impurities in solution and/or oxidation of the impurities limits fouling problems associated with generating the steam from water recycled in thermal processes, such as steam assisted gravity drainage (SAGD), for recovering the oil.

Abstract: Systems and methods relate to vaporizing water into steam, which may be utilized in applications such as bitumen production. The methods rely on indirect boiling of the water by contact with a substance such as solid particulate heated to a temperature sufficient to vaporize the water. Heating of the solid particulate may utilize pressure isolated heat exchanger units or a hot gas recirculation circuit at a pressure corresponding to that desired for the steam. Further, the water may form part of a mixture that contacts the solid particulate and includes a solvent for the bitumen in order to limit vaporization energy requirements and facilitate the production.

Abstract: Methods and systems relate to generating steam from water that may be recycled in thermal oil recovery processes and is heated in tubes having non-obtrusive features to limit fouling formation. The tubes may include jets to generate enhanced flow mixing along an inner wall of the tubes in order to increase heat transfer and disrupt bubble nucleation. Employing the tubes with the inner wall having an average surface roughness of less than one micron may further facilitate disruption of the bubble nucleation.
