Patent DE-4026733-A1 (DE)
Inventor: KORTE HERM-JOS DIPL ING DR
IPC: B01D53/34
Filed: 1990-08-24
Abstract: The invention concerns a process for purifying an oxidation waste gas evolved in a pressurized reaction process and laden with aliphatic and/or aromatic substances, using a waste gas wash. The waste gas to be purified is evolved, in particular, in an oxidation process operated with a gas containing oxygen, e.g., the air oxidation of paraxylol (p-X) by the so-called Witten DMT process for producing dimethylterephthalate (DMT). The waste gas undergoes absorption purification under pressure. The absorbent consists predominantly of an ester or a mixture of esters which has a higher boiling point than the substances to be removed by washing. The process preferably includes the following main steps: a) partial condensation at approximately 35-60  DEG C of the substances to be removed by washing; b) absorption with paratoluyl acid methyl ester (p-TE) or a mixture of p-TE and benzoic acid methyl ester (BME); c) absorption with BME and/or methanol; d) absorption with water; e) combustion under pressure, possibly with a supply of oxygen and combustible products.

Title: Heat exchangers prodn. with single- or alternate sided channels - involves placing two metal sheets e.g. aluminium on elastic plate in chamber and expanding them under pressure
Inventor: EBERT SIEGFRIED DIPL ING
IPC: B21D53/04
Filed: 1991-05-02
Abstract: Prodn. of heat exchangers involves expanding cpd. metal sheets to form single or alternative medium-conducting systems. USE/ADVANTAGE - Used for producing heat exchangers in refrigerators or motor vehicles. Ancillary operations for sealing the process chamber are eliminated, savings in material are achieved and fitting-out time is reduced. In an example two aluminium (99.5%) sheets to equal thickness are placed on an elastic plate in the bottom of the process chamber of an expanding tool. The plate lies under the region where the channels will be formed. On closing the processing chamber, the cpd. sheet is secured against the plate which is then prestressed to a pressure pv = 0.5Mpa. Subsequently expansion of the medium-conducting system is commenced in that the outward opening channel section on the cpd. face of the sheet is subjected to compressed air at pe = 8MPA. By maintaining the expansion conditions pe greater than pv, the conducting channel system is formed.
