Abstract: A method for selecting a solvent or mixture of solvents useful for mitigating deposit formation, cleaning existing deposits, and/or decreasing the rate of deposit formation is disclosed. Decreasing the rate at which deposits may form and/or increasing the rate at which deposits may be removed can dramatically improve process economics (e.g., decreasing down time as a result of deposit formation). In one aspect, embodiments disclosed herein relate to a process for dispersing foulants in a hydrocarbon stream, including the steps of: determining a nature of foulants in a hydrocarbon stream; selecting a solvent or a mixture of solvents suitable to disperse the foulants based upon the determined nature; and contacting the foulants with the selected solvent or mixture of solvents.

Abstract: Embodiments disclosed herein relate to systems and processes for producing olefins and/or dienes. The systems and processes may include thermally cracking a C1-C4 hydrocarbon containing feed to produce a cracked hydrocarbon effluent containing a mixture of olefins and paraffins. The systems and processes may also include dehydrogenating the cracked hydrocarbon effluent to produce a dehydrogenated hydrocarbon effluent containing additional olefins and/or dienes.

Abstract: Se describe un método para seleccionar un solvente o mezcla de solventes útiles para mitigar la formación de depósitos, limpiar los depósitos existentes, y/o disminuir la tasa de formación de depósitos. La disminución de la tasa a la cual pueden formarse depósitos y/o el incremento de la tasa a la cual pueden retirarse los depósitos, puede mejorar dramáticamente la economía del proceso, (e.g., disminuir el tiempo inactivo como resultado de la formación de depósitos) En un aspecto, las modalidades descritas en la presente se refieren a un proceso para dispersar bioincrustaciones en una corriente de hidrocarburos, que incluye las etapas de: determinar la naturaleza de las bioincrustaciones en una corriente de hidrocarburos; seleccionar un solvente o una mezcla de solventes adecuados para dispersar las bioincrustaciones en base a la naturaleza determinada; y poner en contacto las bioincrustaciones con el solvente o mezcla de solventes seleccionados.
