FIELD: chemical, oil refining, petrochemical industries.
SUBSTANCE: invention relates to the chemical, oil refining, petrochemical and other industries for the production of hydrogen and its transport over long distances. The complex includes a pure hydrogen production and extraction unit, a hydrogenation unit, a tank farm, a distribution terminal, an onshore main pipeline, a loading station interconnected by pipelines, and an unlimited number of hydrogen consumer enterprises. The pure hydrogen production and separation unit contains a unit for producing hydrogen from a hydrogen-containing gas and/or an electrolysis plant, a pure hydrogen production unit, arranged in series, the hydrogenation unit contains an aromatic hydrocarbon hydrogenation unit to produce naphthenic hydrocarbon and a naphthenic hydrocarbon purification unit from impurities of volatile components, the tank farm contains storage tanks for naphthenic and aromatic hydrocarbons. The resulting naphthenic hydrocarbon enters the tank farm for storage or is sent to a distribution terminal for transportation using an onshore main pipeline and/or to a loading station with supply to transport tankers and/or rail and/or road tanks for transportation to an unlimited number of consumer enterprises, each of which contains a naphthenic hydrocarbon storage tank, a naphthenic hydrocarbon dehydrogenation unit to produce hydrogen and an aromatic hydrocarbon, an aromatic hydrocarbon storage tank. Aromatic hydrocarbon from consumer enterprises is transported to the tank farm through pipelines or using transport tankers and/or rail and/or road tanks for use as a reagent or for sale as a commercial product. Before transportation, an organic diluent is added to the naphthenic and/or aromatic hydrocarbons.
EFFECT: invention provides both environmentally friendly production of hydrogen and safe technologically simplified its transportation to consumers.
