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: Processes for production of olefins from hydrocarbon feedstocks are provided. In one aspect, the processes of the present invention utilize coils passing through a pyrolysis furnace to partially convert a hydrocarbon feedstock to olefins, followed by further conversion of the hydrocarbon feedstock in an adiabatic reactor. A portion of the coils in the pyrolysis furnace carry the hydrocarbon feedstock and the remainder carry steam only. After a selected period of time, the material flowing through the coils is switched. By flowing steam through the coils that had previously contained the hydrocarbon feedstock, on-line decoking can occur. In another aspect, a high temperature reactor is used to convert methane or natural gas to olefins.
Abstract translation: 提供了从烃原料生产烯烃的方法。 在一个方面，本发明的方法利用通过热解炉的线圈将烃原料部分地转化为烯烃，随后在绝热反应器中进一步转化烃原料。 热解炉中的一部分线圈携带烃原料，其余部分仅带有蒸汽。 在选定的时间段之后，流过线圈的材料被切换。 通过使蒸汽流过先前含有烃原料的线圈，可能发生在线除焦。 另一方面，使用高温反应器将甲烷或天然气转化为烯烃。

Abstract: Randomly packing with filler material at least part of a pass in a coil used in a system for pyrolyzing hydrocarbon feedstock to lighter hydrocarbons. Randomly packing increases heat transfer and decreases the rate of coke build-up within the coil, yielding an improvement in overall system efficiency. Packing material can comprise or be treated with a suitable catalyst for increasing the rate of chemical decomposition, thus further improving system efficiency.
