Abstract: A method for degumming and esterification of an oil comprising fatty acid glycerides, free fatty acids, and phospholipids comprises the steps of mixing the oil, a C1 to C5 monohydric alcohol, and methanesulfonic acid to form a reaction mixture, and heating the reaction mixture to esterify the free fatty acids and produce a fatty acid alkylester and water, and to degum the oil. The method further comprises the steps of causing a phase separation between a first phase comprising the C1 to C5 monohydric alcohol, phosphorous compounds, and water, a second phase comprising the fatty acid glycerides and the fatty acid alkylester, and a residual solid phase. Once the phase separation occurs, the second phase is separated from the first phase and the residual solid phase.

Abstract: A composition for dissolving and/or inhibiting deposition of scale on a surface of a system comprises an acidic component, a wetting agent, and a corrosion inhibitor. The composition may further comprise water. The acidic component comprises an alkanesulfonic acid, e.g. methanesulfonic acid (MSA). The wetting agent comprises a surfactant. The corrosion inhibitor comprises an amphoteric surfactant. The alkanesulfonic acid is present in an amount of at least about 50 weight percent (wt%), the surfactant is present in an amount of from about 0.1 to about 30 wt%, and the amphoteric surfactant is present in an amount of from about 0.025 to about 20 wt%, each based on 100 wt% of the alkanesulfonic acid, the surfactant, and the amphoteric surfactant combined. A method of dissolving and/or inhibiting deposition of scale on the surface of the system comprises the step of contacting the surface of the system with the composition.

Abstract: Se describe un método para disolver y/o inhibir la depositación de incrustaciones sobre una superficie de un sistema, que consiste en el paso de poner la superficie del sistema en contacto con una composición. La composición puede contener desde aproximadamente 3 hasta aproximadamente 15 partes en peso de un componente quelante. El componente quelante se selecciona del grupo de MGDA, NTA, HEDTA, GLDA, EDTA, DTPA y mezclas de estos. La composición además puede contener desde aproximadamente hasta aproximadamente 15 partes en peso de un componente ácido, el cual es diferente del componente quelante. La composición además puede contener al menos alrededor de de 60 partes en peso de agua. Cada uno de los intervalos de las partes en peso antes mencionados se basa en 100 partes en peso de la composición. La composición además puede contener un componente tensoactivo y/o un inhibidor de la corrosión.

Abstract: A method of dissolving and/or inhibiting the deposition of scale on a surface of a system comprises the step of bringing the surface of the system into contact with a composition. The composition can comprise from about 3 to about 15 parts by weight of a chelating component. The chelating component is selected from the group of MGDA, NTA, HEDTA, GLDA, EDTA, DTPA, and mixtures thereof. The composition can further comprise from about 3 to about 15 parts by weight of an acidic component, which is different than the chelating component. The composition can further comprise at least about 60 parts by weight of water. Each of the parts by weight ranges above are based on 100 parts by weight of the composition. The composition may further comprise a surfactant component and/or a corrosion inhibitor.
