Abstract:
A process for filling a sorption store (50) with a gas (51), wherein at least one gas adsorbent medium (60) is disposed within at least one vessel, comprising a last step (26) wherein a last portion of an entire amount of the gas (51) to be filled into the sorption store (50) is fed at a maximum feed rate, said feed rate defined as an amount of gas (51) filled into the sorption store (50) per time unit, and wherein the last portion of the entire amount of the gas (51) to be filled into the sorption store (51) is the difference between at least 20% and 100%, in particular the difference between at least 40% and 100%, by weight of gas relating to the total weight of gas to be stored.
Abstract:
An apparatus (10) for preparation of acetylene and synthesis gas by partial oxidation of hydrocarbons with oxygen is proposed, comprising a reactor (12). The reactor (12) has a burner block (14) with a firing space for acetylene preparation, a secondary space (18) formed within the burner block (14), and an annular space (20) surrounding the secondary space (18). The burner block (14) has holes (22) for supply of a stream of a mixture of hydrocarbons and oxygen to the firing space and holes (24) for supply of a stream of auxiliary oxygen to the firing space. The holes (24) for supply of a stream of auxiliary oxygen to the firing space are connected to the secondary space (18). The secondary space (18) is connected to the annular space (20).There is a further proposal of a process for preparing acetylene and synthesis gas by partial oxidation of hydrocarbons with oxygen.
Abstract:
A process for indicating a fill level of a sorption store (1), wherein at least one gas adsorbent medium (5) is disposed within at least one vessel (3) and wherein a total amount (ntotal) of a gas (15) stored in the sorption store (1) is computed based on at least one measured temperature value and at least one measured pressure value.
Abstract:
What is proposed is a column (K) comprising separatory internals (E) for separating a mixture of hydrocarbons and/or hydrocarbon derivatives (1) by extractive distillation with a selective solvent (2), with supply of the selective solvent (2) in the upper region of the column and supply of the mixture of hydrocarbons and/or hydrocarbon derivatives to be separated (1) below the supply of the selective solvent (2), the selective solvent (2) becoming laden in the column (K) with the components from the mixture to be separated (1) for which it has greater affinity and being withdrawn from the lower region of the column as laden selective solvent (3), while, by contrast, the components from the mixture to be separated for which the selective solvent (2) has a lower affinity remain in the vapor phase and are withdrawn as top stream (4), which is completely or partially condensed to obtain a condensate (5), some of which is withdrawn as product stream (6), the remainder being reintroduced to the column (K) as reflux (7), wherein said column comprises in the region of the column above the separatory internals (E) a first, substantially horizontal feed pipe (R1) for supplying the selective solvent, wherein the first, substantially horizontal feed pipe (R1) exhibits a cross-sectional narrowing to a narrowest point (V), said pipe widening again downstream of the cross-sectional narrowing, and wherein said column comprises a second feed pipe (R2) for supplying the reflux (7), said pipe joining the first, substantially horizontal feed pipe (R1) in the region of the narrowest point (V) of the cross-sectional narrowing.
Abstract:
An apparatus (10) for preparing acetylene and synthesis gas by partial oxidation of hydrocarbons with oxygen is proposed, comprising a mixing unit (12), a mixing section and a mixing diffuser (16). The mixing unit (12) has a feed orifice (18) for supply of a hydrocarbonaceous stream, a feed orifice (20) for supply of an oxygenous stream, a swirl register and a distributor plate (24). The distributor plate (24) is disposed between the mixing section (14) and the feed orifice (18) for supply of a hydrocarbonaceous stream. The distributor plate (24) has orifices (28). The swirl register (22) is disposed between the feed orifice (20) for supply of an oxygenous stream and the mixing section (14). The mixing diffuser (16) is connected to the mixing section (14).There is a further proposal of a process for preparing acetylene and synthesis gas by partial oxidation of hydrocarbons with oxygen.
