摘要:
The disclosed invention relates to a process and apparatus for converting natural gas to higher molecular weight hydrocarbons. The process includes steam reforming to form synthesis gas followed by a Fischer-Tropsch reaction to convert the synthesis gas to the high molecular weight hydrocarbons. The reforming and Fischer-Tropsch reactions are conducted in microchannel reactors. The higher molecular weight hydrocarbons may be further treated to form hydrocarbon products such as middle distillate fuels, lubricating oils, and the like. The apparatus includes vessels containing SMR microchannel reactors and Fischer-Tropsch microchannel reactors. A composition comprising a mixture of olefins and paraffins is disclosed.
摘要:
The disclosed invention relates to a miniplant with a distillation process for separating two or more components having different volatilities from a liquid mixture containing the components. The process employs microchannel technology for effecting the distillation and is particularly suitable for conducting difficult separations, such as the separation of ethane from ethylene, wherein the individual components are characterized by having volatilities that are very close to one another. The process involves a microchannel distillation assembly which comprises at least one microchannel distillation unit with a height of up to about 3 meters, whereby the microchannel distillation unit comprises a plurality of microchannel distillation sections each having a height of up to 1000 mm. The process further involves to treat the distillate product which is formed in a first microchannel distillation unit, in another microchannel distillation unit and to treat the bottoms product which formed in the first microchannel distillation unit, in another microchannel distillation unit.
