Definitions
- the invention relates to a reaction vessel, suitable for carrying out an exothermic reaction of a liquid reactant with a gaseous reactant to a gaseous reaction product at elevated temperature and elevated pressure, wherein the residence time of the gaseous reactant in the reaction vessel is increased by non-pressurized internals.
- hydrogen sulfide is preferably prepared from sulfur and hydrogen.
- the reaction vessel contains internals which increase the residence time of the hydrogen in the liquid sulfur, wherein the gas is collected in parts of these internals and then redistributed in the liquid sulfur.
- hydrogen sulfide is an industrially important intermediate, for example for the synthesis of methylmercaptan, dimethyl sulfide, dimethyl disulfide, sulfonic acids, dimethyl sulfoxide, dimethyl sulfone, as well as numerous sulfidation reactions.
- Hydrogen sulphide from sulfur and hydrogen is above all the temperature control. High temperatures are necessary to achieve an equilibrium state where a molar ratio of hydrogen: sulfur in the gas phase of about 1: 1 is established. Only this allows the synthesis of pure hydrogen sulfide. With increasing pressure, the temperature must be increased sharply according to the vapor pressure curve of sulfur in order to achieve the desired molar ratio of 1: 1 in the gas phase. There are already slight differences in the pressure of z. B. 1 bar and less of great importance.
- CSSR 190792 describes a process variant for the production of hydrogen sulfide, wherein high reaction temperatures are avoided by a comparatively complicated series connection of several reactors. High temperatures are avoided there especially due to corrosion problems.
- Czechoslovakia 190793 is reported from strong corrosion of the plant from temperatures of 400 0 C.
- the object of the invention is to provide a reaction vessel and a process for the production of hydrogen sulfide from sulfur and hydrogen at pressures> 5 bar, without causing high temperatures severe corrosion of pressure-bearing parts.
- the invention relates to reaction vessels, suitable for carrying out an exothermic reaction of a liquid reactant with one or more, in particular a gaseous reactant to a gaseous Reaction product at elevated temperature and elevated pressure, wherein the residence time of the / of the gaseous reactants in the reaction vessel is increased by non-pressurized internals.
- liquid reactant generally passes into the gaseous state before the reaction.
- the non-pressurized internals are surrounded by the liquid reactants.
- Reactor concepts have now been found for such exothermic syntheses at higher pressure that help avoid high overpressure temperatures on pressurized parts.
- local overheating temperatures in the area of the internals are used selectively in order to enable rapid and complete conversion of the hydrogen with a high space-time yield.
- the heat of reaction for the heating and evaporation of the starting materials in this case sulfur, can be used.
- the starting materials themselves can be used.
- the sulfur-saturated in the liquid sulfur phase finely distributed hydrogen is collected there again as a contiguous gas phase.
- the residence time of the gaseous reactants in these gas collection areas or gas trap constructions is significant as compared to the residence time of rising gas bubbles in reactors without internals, i. increased by about the factor 3 to 20, especially 5 to 15. If the residence time of the hydrogen in the liquid sulfur is too short, hydrogen enriched with gaseous sulfur will collect in the region above the liquid sulfur in the reactor and convert to hydrogen sulphide. It follows that reaction vessels without the inventive fittings by the amount of heat released above the liquid sulfur strongly heat, because the energy can not be dissipated satisfactorily. According to the invention, due to the increased residence time in the region of the reactor filled with liquid sulfur, no reaction mixture enters the space above the liquid sulfur. According to the invention, therefore, the resulting amount of heat only within the gas collection areas or

- the present in the gas collection areas or the internals temperatures can be more than 550 0 C. These temperatures were not tolerable for the pressure-bearing jacket for corrosion and safety reasons. Become several gas catchments in one
- Reaction container arranged, this is preferably done in the flow direction of the rising hydrogen.
- the size of the gas collection or gas capture volumes of the individual internals may increase, decrease or be constant. Preference is given to an increase of the collection volumes in the flow direction in order to reduce the z.
- the internals are surrounded by liquid sulfur.
- the gas collection areas and associated internals are cooled by the surrounding liquid sulfur.
- a flow distribution of the liquid reactant realized in particular of sulfur, which allows a circulation of sulfur and thus a good heat distribution. Particular attention is paid in the liquid-filled space between the internals and the pressure-bearing jacket on a sulfur circulation. Also by the location of supply of the fresh sulfur and / or by recycling unreacted sulfur, the circulation and the heat balance in the reactor can be controlled in a targeted manner.
- the sulfur additions and returns are preferred for
- the gas collection areas or gas catch areas and associated internals are preferably fixed to one or more inner tubes and are in the pressure vessel.
- methods known to those skilled in the art, such as welding, are used.
- suitable filler metals for surface treatment or for joining components such as
- Welding consumables are used.
- the use of special materials or ceramics is advantageous here due to high temperatures. If conventional stainless steel is used for the gas-trapping constructions, this is preferably carried out there with a corrosion allowance of more than 1 mm.
- the internals are mounted so that they can be pulled from the top of the reactor, for example with the aid of a crane.
- the invention relates to a process for the exothermic reaction of a liquid reactant with one or more gaseous reactants to a gaseous reaction product at elevated temperature and elevated pressure in a reaction vessel in which the residence time of the gaseous reactant in the reaction vessel is increased by non-pressurized internals, and the non-pressurized internals are surrounded by the liquid reactant.
- the invention also relates to the production of hydrogen sulfide from hydrogen and sulfur at elevated pressure and high temperatures, using the reaction vessel according to the invention.

- the gas collection areas or gas capture areas or the internals are preferably temperatures above 450 0 C. before, in particular up to 600 0 C.
- the non-liquid sulfur covered areas of the reactor are preferably above the liquid
- the container preferably has a cylindrical shape.
- the non-pressure-bearing internals acting as gas collecting areas or gas-catching areas may be present, for example, in the form of inverted cups or caverns, floor constructions with gas collectors and gas distributors, fillings of fillers or hollow bodies, packings, monoliths, knitted fabrics or combinations thereof.
- FIG. 1 shows an example of an embodiment
- the skilled person is free in the selection of the process steps to be combined for the production of hydrogen sulfide, whereby more of the reaction vessels according to the invention and various apparatus for the separation of by-products or unused starting materials can be combined.
- the process is carried out at a pressure of 5 to 20 bar and passes hydrogen at this pressure in the reaction vessel according to the invention in liquid sulfur.
