摘要: The invention relates to a process for preparing tertiary alkyl ethers. According to the process the feedstock containing hydrocarbons is fed to a catalytic distillation reactor system, in which the isoolefines, in particular the C.sub.4 to C.sub.7 isoolefines, of the feed are reacted with an alkanol in the presence of a cation exchange resin in order to produce tertiary alkyl ether products. The reaction product containing the ethers is removed from the distillation system as the bottoms product and, if necessary, it is subjected to an additional treatment for producing a gasoline component. The unreacted alkanol is removed as the overhead product of the distillation. According to the invention, the distillate withdrawn mainly contains an azeotrope of C.sub.4 hydrocarbons and alkanol, the C.sub.4 amount of which at least approximately corresponds to the C.sub.4 hydrocarbon concentration of the hydrocarbon feed, a substantial amount of the unreacted alkanol being removed in the form of said azeotrope. By means of the invention the need for a separate alkanol washing unit is eliminated in the apparatus which considerably reduces apparatus investment costs.

摘要: A process for producing tertiary alkyl ethers by reacting an olefinic hydrocarbon feedstock, which contains a mixture of reactive C.sub.4 -C.sub.7 isoolefins, with an alkanol in the presence of a catalyst that will enhance the reaction between the isoolefins and the alkanol. By adjusting the weight ratio of the isobutylene to the reactive C.sub.6 isoolefins of the feed to a value of about 0.2 to 10, it is possible to increase the conversion of reactive C.sub.4 's to over 95%, of reactive C.sub.5 's to over 85% and of reactive C.sub.6 's to over 57%.

摘要: The present invention relates to a feed distribution device in separation columns and a method of operation. In particular it relates to distillation columns in which the feed stream is substantially liquid phase, or a mixture of gas and liquid upstream of the column, but where the feed vaporizes or vaporizes more when it enters the column. More specifically, the feed distribution device contains a plurality of opening which allow the feed to vaporize inside the column and where the openings are maintained in critical condition during operation. Significant advantage is achieved through the implementation and use of the present feed distribution device.

摘要: A separation column containing a feed distribution device and a feed distribution device for a separation column, such as a vacuum distillation column. The feed distribution device being capable of diffusing and directing a feed flow from a feed inlet so as to distribute the feed substantially evenly over the surface area of a separation plate in the column thereby increasing the columns efficiency. The separation column containing the feed distribution device being capable of shorter height, less costly design and lower operating cost than a separation column without the feed distribution device.

By means of the invention the need for a separate alkanol washing unit is eliminated in the apparatus which considerably reduces apparatus investment costs.
