    • A procedure for preventing hydrocarbon emissions when liquid hydrocarbons with high vapour pressure are stored in rock cisterns (11). The rock cistern (11) is kept completely closed during withdrawal as well as filling. When the cistern (11) is emptied, the pressure in the gas space is elevated by heating. The surface layer of the liquid in the cistern (11) is heated, and heated hydrocarbons are conducted into the cistern (11). When the cistern is emptied, part of the liquid flow is conducted to a heat exchanger (15), in which it is heated, and conducted back into the cistern (11). From the surface layer of the liquid in the cistern (11) a liquid flow is pumped to the heat exchanger (15), where it is heated, and conducted back into the gas space (17) of the cistern (11).

    • The invention relates to a process for preparing tertiary methyl ethers. According to the process the feedstock containing hydrocarbons is fed to a catalytic distillation reactor system, in which the isoolefines, in particular the C4 to C7 isoolefines, of the feed are reacted with methanol in the presence of a cation exchange resin in order to produce tertiary methyl 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 methanol is removed as the overhead product of the distillation. According to the invention, the distillate withdrawn mainly contains an azeotrope of C4 hydrocarbons and methanol, the C4 amount of which at least approximately corresponds to the C4 hydrocarbon concentration of the hydrocarbon feed, a substantial amount of the unreacted methanol being removed in the form of said azeotrope. By means of the invention the need for a separate methanol washing unit is eliminated in the apparatus which considerably diminishes apparatus investment costs.

    • The present invention relates to a process and an apparatus for producing tertiary alkyl ethers from isoolefins and alcohols. According to the process, the isoolefins and alcohols are reacted with each other in a reaction space (31) in the presence of a cation exchange resin for forming the ethers. The process is carried out in an reactor vessel comprising a lower section in which a fluidized-bed section (35) can be formed, and an upper section in which a fixed-bed section (36) can be formed, respectively. The inlet nozzle (30A) for initial reactant mixture feed is adapted to the reactor vessel lower section and the outlet nozzle (30B) for removal of reaction products is adapted to the reactor vessel upper section, respectively. According to the invention the fixed reaction bed (36) is advantageously achieved by using a reactor equipped with an expansion section (37) above which the reactor cross-sectional area is increased sufficiently to reduce the superficial velocity of the liquid upflow from the reactor lower section to the upper section below the minimum fluidization velocity. By virtue of the invention, the catalyst contained in the fixed bed can be changed even during run by temporarily reducing the superficial liquid velocity so much as to allow the catalyst particles contained in the fixed bed to fall by gravity to the lower section of the reactor, wherefrom the spent catalyst can be unloaded as necessary and replaced by new catalyst.

    • The invention concerns a process and an apparatus for preparing tertiary ethers. According to the process, C4 to C6 isoolefins and possibly heavier olefins contained in the feedstock are reacted with lower aliphatic alcohols, in particular methanol or ethanol, in a catalytic distillation reactor system in order to produce the corresponding ethers. According to the invention, the reaction between the isoolefins and the alcohols is essentially carried out in at least one reactor (5-7) of the kind, which is combined with a distillation column (3) intended for product separation, by conducting at least a part of the liquid flow of the column through the reactor and returning it to a lower tray than the one from which it was taken. At least half of cation exchange resin is placed in the side reactor (5-7). In the process according to the invention, the catalyst can be rapidly changed without stopping the process. In order to improve conversion additional alcohol can be fed to at least one of the side reactors.
