Abstract: The alcohol, ether and hydrocarbon components of the reaction effluent from various etherifications of C4 or C5 isoolefins with an alcohol such as methanol or ethanol which produce MTBE, ETBE, TAME, or TAEE are separated using identical process equipment. The components are recovered by first removing a portion of the alcohol in a first water extraction step, then fractionating the ether, followed by the removal of additional alcohol in a second water extraction step and then fractionating the alcohol. Hydrocarbons are recovered from a extract stream of the second water extraction step.

Date Oct. 27, 1994A method and apparatus to clean a filter drum used for thickening lime mud. The drum is rotated about a horizontal axis in a first direction so that the circumferential surface of the drum moves into contact with lime mud in a vat and a precoat layer formed on the drum, as well as an external layer of lime mud which forms a thickened lime mud cake when a vacuum is applied to the drum withdrawing liquid from the lime mud. The thickened external layer of lime mud cake is scraped from the drum at a second side of the vat, and at a first opposite side of the vat a first jet of liquid is directed onto the drum surface (e.g. at a pressure of about 30-100 bar) to remove a strip of the precoat layer, a third jet of liquid cleans the drum after removal of the precoat layer, and a second jet of liquid is directed onto the drum with sufficient intensity (e.g. a pressure of about 2-20 bar) to remove, by spreading and partially detaching, a strip from the thickened lime mud cake. Typically the second jet is operated substantially continuously, except when the first and third jets are operated, the first and third jets being operated at spaced time intervals (e.g. periodically or intermittently). The invention results in partial removal of the precoat with a gentle liquid jet, easy removal of the entire precoat layer because the precoat is not yet hardened at its location of movement, intermittent use of high pressure jets which extends the life of the high pressure apparatus in the wire forming the drum, and optimum ease of installation and maintenance of the spray nozzles.

Filed: 1995-07-03
Abstract: A typical traditional reactor for hydrogenation consists of a tank filled with a liquid and a gas and a small particle catalyst. The reaction is carried out at high pressures and high temperatures. Lack of gas on the catalyst surface limits the velocity of reaction. Much work has been done to increase the quantity of gas on the catalyst. It has not been possible to solve this problem effectively with the techniques of today. According to the invention an extra solvent is added to the reaction mixture. By bringing the whole mixture (solvent, substrate, hydrogen and reaction products) to super-critical or near-critical state, a substantially homogeneous mixture can be obtained. By this method it is possible to control the concentration of gas on the catalyst to the desired level. The velocity of reaction is thereby increased considerably. The hydrogenation reactions principally involved comprise hydrogenation of carbon-carbon double bonds (C=C) in lipids; hydrogenation of COOR to C-OH and HO-R to produce fatty alcohols; and direct hydrogenation of oxygen to hydrogen peroxide.
