Inventor: ZILLMANN REINHOLD
IPC: C07C17/02
Filed: 1984-08-24
Abstract: 1. A process for the production of trans 1,1,2,3,4,4-hexabromo-2-butene by bromination of diacetylene, characterised in that the diacetylene from the hydrocarbon residue arising in the acetylene recovery operation is dissolved at a temperature of -20 degrees C to + 20 degrees C and a pressure of 1 to 2 bar in a solvent containing a hydroxyl group, initially a mixture rich in vinylacetylene is separated off in a first desorption stage at a temperature of 0 to 30 degrees C and a pressure of 1 to 2 bar with an inert gas, then a gas mixture rich in diacetylene is desorbed in a second desorption stage at a temperature of 0 to 30 degrees C and a pressure of 1 to 2 bar with an inert gas, this diacetylene-rich gas mixture is brominated in a reactor in which excess bromine dissolved in a halohydrocarbon has previously been placed, water optionally being added to the halohydrocarbon, at a temperature of 20 to 40 degrees C and a pressure of 1.2 to 2 bar to form trans 1,1,2,3,4,4- hexabromo-2-butene, gaseous bromine being additionally fed to the reactor with the reaction gas, and the bromine-containing offgas is optionally reacted in an after-reactor with excess diacetylene in a halohydrocarbon.

Title: Claus residual gas cleanup using tetraethylene glycol dimethyl ether as so2 scrubbing agent
Inventor: HEISEL MICHAEL
IPC: B01D53/14
Filed: 1984-09-20
Abstract: A process is disclosed for the purification of a gaseous stream contaminated at least with CO2 and H2S. The gaseous stream is preheated and subjected, in the presence of recycled SO2, to a catalytic conversion of H2S into elemental sulfur. The thus-obtained sulfur is separated, and the residual gas, which contains at least H2S, SO2, CO2, and water, is freed absorptively from SO2 after oxidative conversion of H2S to SO2. It is proposed that the residual gas, after oxidative conversion of H2S to SO2, is cooled in heat exchangers, preferably regenerators, and is subsequently scrubbed with a solvent consisting predominantly of tetraethylene glycol dimethyl ether.

Title: Plastic extrusion.
Inventor: JARVENKYLA JYRI
IPC: B29C48/94
Filed: 1997-03-26
Abstract: A method for making a product to be extruded and an extruder. The extruder has at least two conical stators and at least one conical rotor placed rotatably between the stators. The extruder further has supply conduits for feeding the material to be extruded separately into the exterior and interior of the rotor.

Granted: 2006-02-15
Abstract: A method of determining a vertical component of particle velocity from seismic data acquired using at least one receiver disposed within a water column includes determining the vertical component of particle velocity from the pressure at a first location and a second location. The first location is the location of a first receiver, and is vertically beneath the second location.
