A steady-state device and method for industrially synthesizing hydrogen sulfide gas

Abstract

The invention discloses a steady-state device and method for industrially synthesizing hydrogen sulfide gas. The device comprises a liquid sulfur storage and transportation unit, an H2 input unit, anH2S synthesis unit, an H2S purification unit and an H2S cooling and storage unit. The liquid sulfur storage and transportation unit and the H2 input unit are respectively connected with the H2S synthesis unit, the H2S purification unit is connected with the H2S synthesis unit, and the H2S cooling and storage unit is connected with the H2S purification unit. According to the invention, the continuity, stability and system intrinsic safety of industrial production are taken as starting points, hydrogen and sulfur are taken as raw materials, and the long-period steady-state production of high-purity hydrogen sulfide is realized through process configuration. The device and the technology disclosed by the invention have the characteristics of few system byproducts, strong energy-saving and environment-friendly properties, low unit consumption of a hydrogen sulfide product, excellent system operation economy and the like.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and in particular relates to a device and a method for industrially synthesizing hydrogen sulfide gas. Background technique [0002] Hydrogen sulfide is a highly toxic and extremely dangerous inorganic compound. As an important chemical raw material, it is often used to prepare organic and inorganic sulfides. Sexual processing and other fields. In recent years, with the country's emphasis on the field of environmental protection, hydrogen sulfide, as a clean and efficient reducing agent, has been widely used in the field of heavy metal wastewater treatment, especially for the multi-component and heavy metal content of non-ferrous metal smelting. High complex mining and metallurgy wastewater. [0003] In industry, sulfur-containing compounds such as sodium sulfide and pyrite are commonly used to decompose hydrogen sulfide with acid. However, due to the disadvantages of unstable gas pro...
