  • the present invention relates to a process for the upgrading of natural gas containing hydrogen sulfide in concentrations higher than or equal to 60% by volume by the recovery of hydrogen from both the sulfurized compound and hydrocarbon phase present.
  • natural gas essentially consists of methane, but, in addition to significant traces of higher C 2 -C 7 + hydrocarbons, it can also contain variable quantities of inert gases or pollutants, for example carbon dioxide or nitrogen, whose presence must be eliminated or reduced to satisfy the specifications of use.
  • Fields/reservoirs of natural gas with a high hydrogen sulfide content can be found all over the world, for example Bearberry fields or Panther River in Canada are natural gas reservoirs containing approximately 90% by volume and 68% by volume of H 2 S, respectively. In the United States there are fields such as Black Creek and Cox (Missisipi) which contain approximately 78% and 65% of H 2 S, respectively. "Super- sour" gas fields having large dimensions also exist, such as the Zhaolazhuang-Hebei field in China which comprises 19 wells which produce a natural gas whose concentration of H 2 S varies from 60 to 90% by volume.
  • superacid gas reservoirs also known as "super-sour” gas reservoirs
  • These superacid gas reservoirs either remain unused, as the recovery of natural gas (methane) is too onerous, or, as in the case of the Zholazhuang field, they are used for the production of sulphur by means of the Claus process, sending the gaseous stream, substantially as it leaves the production well, directly to the combustion reactor where the partial oxidation of the hydrogen sulfide to SO 2 , takes place.
  • the methane present is burnt and this is an economic loss which becomes increasingly more significant, the higher the methane content in the natural gas .
  • Hydrogen is a raw material which is extremely requested in refineries, for example, for all hydrotreatment processes such as hydrocracking and hydrodesulfurization, and it would therefore be extremely desirable to be able to obtain it from a source with zero value such as current "super-sour" natural gas reservoirs .
  • a method which allows hydrogen to be recovered from natural gas, strongly acid due to hydrogen sulfide, is the reforming reaction with methane according to the reaction:
  • the Applicant has also found that it is possible to use the CS 2 , produced by the reforming reaction between methane and H 2 S, as fuel for sustaining the reaction
  • the previous endothermic reforming reaction of H 2 S with methane can be sustained without having to burn any high-quality fuel.
  • the SO 2 produced by the combustion can be upgraded downstream as intermediate for specific synthesis reactions, for example to produce sulfuric acid, or it can be disposed of by injection into the subsoil.
  • a further preferred aspect of this reaction is the use of the mixture thus formed of carbon monoxide and hydrogen, after the separation of the water, for the production of methanol according to:
  • An object of the present invention therefore relates to a process for upgrading superacid natural gas, with a content of hydrogen sulfide higher than or equal to 60% by volume, with the production of hydrogen, which comprises. a. feeding the superacid natural gas to a reforming reactor operating at a temperature ranging from 900 to 1500 0 C and at atmospheric pressure, or slightly lower than atmospheric pressure, for example ranging from 0.08 to 0.1 MPa, to produce a mixture essentially consisting of carbon disulfide (CS 2 ) and hydrogen (H 2 ) ; b. cooling the reaction products, separating the carbon disulfide from the remaining reaction mixture containing hydrogen and recovering the hydrogen; c.
  • step (d) burning the carbon disulfide with a gas containing oxygen to produce a gaseous mixture, essentially consisting of CO 2 and SO 2/ at a high temperature; d. feeding at least a part of the hot gases of the combustion of carbon disulfide to the reforming step, as heat source for maintaining the endothermic reaction of step (a) ; and e. providing the combustion gases of carbon disulfide, also coming from step (d) , as intermediates for chemical syntheses downstream or for their disposal by injection into specific geological structures.
  • the reaction products can be cooled to a temperature which is optimum for the subsequent operations, for example to a temperature lower than 50 0 C, in order to recover the carbon disulfide, which is liquid at those temperatures, from the gaseous phase essentially consisting of hydrogen, residual H 2 S and possible reaction by-products and/or hydrocarbons.
  • the gaseous phase can then be treated with conventional methods, for example by means of the selective adsorption technology of the PSA type or treatment with membranes, for the recovery of the hydrogen.
  • the possible H 2 S in excess can be recovered by the traditional techniques, for example by absorption with amines .
  • the cooling phase preferably takes place in heat exchangers where the cooling liquid is water, which can be transformed into vapour at a temperature of 100- 150 0 C and a pressure of 0.2-10 MPa.
  • the vapour can then be used to produce electric energy or as a heat source to be destined for the running of other plants .
  • the reaction products can pre-heat the reagents which are to be fed to the reforming reactor.
  • the carbon disulfide recovered in the liquid state is burnt in a specific reactor, with air or air enriched in oxygen as comburent .
  • the combustion gases leaving the reactor at a temperature of 1000-2500 0 C are fed, either partially or totally, to a further system of heat exchangers to bring the reagents, possibly pre-heated, to the correct temperature, before being introduced into the reforming reactor.
  • a further system of heat exchangers to bring the reagents, possibly pre-heated, to the correct temperature, before being introduced into the reforming reactor.
  • the production of hydrogen can be obtained from a stream containing hydrogen sulfide without having to use any external high-quality fuel and a stream containing SO 2 is also obtained as by-product, which can be advantageously used as raw material for chemical syntheses such as, for example, the production of sulfuric acid.
  • the stream containing SO 2 can be injected into adequate geological structures.
  • An alternative embodiment of the process, object of the present invention envisages that only a part of the CS 2 produced is burnt as energy source, whereas the remaining part is separated and destined for commercialization.
  • the balance between the aliquot of burnt CS 2 and that separated and destined for sale depends on the quantity of heat which is to be produced to sustain the endothermic reforming reaction of methane with H 2 S.
  • the sufficient quantity of CS 2 to be destined for combustion to sustain the reforming of methane with H 2 S is equal to at least 55% by weight of the total CS 2 produced.
  • the remaining part of CS 2 can be separated and sold or burnt to provide heat energy for also sustaining other process equipment, for example for producing high-pressure vapour which can be used in this or other plants .
  • Another innovative aspect of the process, object of the present invention consists of the fact that the sulfur present in the H 2 S molecule is transformed directly into SO 2 , which can in turn be transformed, by reactions and processes well-known in literature, for example, to sulfuric acid, requested by the chemical industry, rather than into elemental sulfur as in the conventional Claus process. Elemental sulfur does in fact have considerable environmental storage problems and many nations in which there are natural gas reservoirs impose heavy economic sanctions for the storage of sulfur. By transforming sulfur to sulfuric acid, on the other hand, a liquid product is obtained, which can be easily transported and sold as such.
