20120119149 | PROCESS AND APPARATUS FOR PREPARING ACETYLENE AND SYNTHESIS GAS - The present invention provides a process for preparing acetylene and synthesis gas by partial oxidation of hydrocarbons with oxygen, by first separately preheating the starting gases comprising a hydrocarbon-containing stream and an oxygen-containing stream and then mixing them in a mixing zone and, after they have flowed through the burner block, reacting them in the firing space and then cooling the products rapidly, wherein the surface on the firing space side of the burner block is covered with a purge gas stream and this purge gas stream is introduced through the burner block by means of several bores, where the averaged ratio of effective surface area of the burner block to number of these bores in the burner block for the purge gas stream is within a range from 5 to 100 cm | 05-17-2012 |
20120119150 | PROCESS AND APPARATUS FOR PREPARING ACETYLENE AND SYNTHESIS GAS - A process for preparing acetylene and synthesis gas by partial oxidation of hydrocarbons with oxygen, by first separately preheating the hydrocarbon gas and oxygen gas, and then reacting the gases and cooling the products rapidly. The reactor wall is blanketed with a purge gas stream, introduced through a plurality of feed lines. These feed lines deliver purge gas in a vector direction within a 10° angle of the main flow direction of the reactive gas stream. The purge gas is delivered at multiple stages relative to the main flow direction of the reactive gas stream, and the free cross section of the firing space available to the reactive gas stream, at the height of the feed lines of the purge gas stream, is approximately constant. | 05-17-2012 |

20120238779 | OPTIMIZED INTRODUCTION OF THE STARTING MATERIALS FOR A PROCESS FOR PREPARING AROMATIC AMINES BY HYDROGENATION OF NITROAROMATICS - The invention relates to a process for preparing aromatic amines by hydrogenation of corresponding nitroaromatics by means of hydrogen, and also an apparatus suitable for this purpose. In particular, the invention relates to a process for preparing toluenediamine (TDA) by hydrogenation of dinitrotoluene (DNT). | 09-20-2012 |
20140097098 | Method of Charging a Sorption Store with a Gas - Described is a method of charging a sorption store with a gas. The sorption store comprises a closed container which is at least partly filled with an adsorption medium and has an inlet and an outlet which can each be closed by a shut-off element. The method comprises the steps: (a) closing of the outlet shut-off element and opening of the inlet shut-off element, (b) introduction of gas to be stored under a predetermined pressure through the inlet, (c) rapid opening of the outlet shut-off element with the inlet shut-off element open so that a gas flow having a predetermined flow rate is established in the container, (d) reduction of the flow rate as a function of the adsorption rate of the gas adsorbed in the store, and (e) complete closing of the outlet shut-off element. | 04-10-2014 |
20140097099 | Sorption Store for Storing Gaseous Substances - Describes is a sorption store for storing gaseous substances. The sorption store for storing gaseous substances comprises a closed tank and a feeding device, which comprises a passage through the tank wall, through which a gas can flow into the tank. The tank has inside it at least one separating element, which is configured in such a way that the interior of the tank is divided into at least one pair of channels comprising two parallel running channel-shaped compartments, the ends of which are in connection with one another in each case by way of a common space, each channel-shaped compartment being filled at least partially with an adsorption medium. The feeding device is designed in such a way that inflowing gas is diverted almost exclusively into one of the two compartments of each pair of channels. | 04-10-2014 |
20140097100 | Method Of Charging A Sorption Store With A Gas - Described is a method of charging a sorption store with a gas. The sorption store comprises a closed container and a feed device which has a passage through the container wall, through which the gas can flow into the container, and the container has at least two parallel, channel-shaped subchambers which are located in its interior and are each at least partly filled with an adsorption medium and whose channel walls are coolable. The method comprises, in a first step, feeding in a gas in such an amount that a pressure in the store of at least 30% of a predetermined final pressure is reached as quickly as possible and, in a second step, subsequently varying the amount of gas fed in in such a way that the course of the pressure in the store approximates the adsorption kinetics of the adsorption medium until the predetermined final pressure in the store is reached after a predetermined period of time. | 04-10-2014 |
