Embodiment Construction

[0027] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0028] Sulfur recovery method in the production of carbon disulfide of the present invention, from the carbon disulfide refining unit containing hydrogen sulfide acid gas (H 2 S content of about 95v%) enters the main burner of the combustion furnace, mixes with a certain proportion of air sent by the combustion furnace blower 20, and burns under oxygen in the combustion furnace 1. ℃, the reaction in the combustion furnace is mainly as follows:

[0029] h 2 S+3 / 2O 2 → SO 2 +H 2 o

[0030] h 2 S+1 / 2SO 2 →H 2 O+3 / 4S 2

[0031] The ratio of acid gas and air is controlled by a ratio regulator, and the amount of air distributed into the combustion furnace is roughly adjusted according to the detected amount of acid gas containing hydrogen sulfide, and according to the outlet connected to the secondary reactor 8 or to the secondary reactor The H a...

Abstract

A method and equipment for recovering sulfur in the production of carbon disulfide. After the high-temperature gas produced by the oxygen-deficient combustion of the hydrogen sulfide-containing acid gas is condensed and separated out of the sulfur, the temperature is raised and sent to the upper part to be filled with an oxygen-leakage protection type catalyst, and the lower part is filled with a hydrolysis catalyst for a first-level reaction. After the reaction, the gas is condensed to separate the sulfur and then heated again and sent to the upper part of the secondary reactor filled with the hydrolysis catalyst, and the lower part is filled with the secondary reactor of the hydrogenation catalyst. Under the action of selective oxidation catalyst, H 2 S is oxidized to S, and the exhaust gas is condensed to separate the sulfur. Using the configuration of "burner + primary and secondary reactors + selective oxidation reactor", the total sulfur recovery rate is increased to more than 98%, and the pollutant SO is reduced while producing more sulfur. 2 The concentration entering the desulfurization unit reduces the difficulty of subsequent exhaust gas treatment, and the return on investment is higher. After the tail gas is desulfurized by wet method, the SO in the tail gas is finally discharged 2 Content<100mg / Nm 3 .

Description

technical field [0001] The invention relates to a sulfur recovery technology, in particular to a sulfur recovery method and equipment in the production of carbon disulfide. Background technique [0002] Carbon disulfide is an important chemical raw material. The raw material routes for producing carbon disulfide mainly include charcoal-sulfur method, coke-sulfur method, natural gas-sulfur method, etc. Although the first two methods have less equipment investment and shorter construction period However, the reaction retort has the disadvantages of short service life, low fuel utilization rate, large consumption of raw materials, large floor area, poor working conditions, low labor productivity and heavy pollution, etc., which have been banned by the state. Using sulfur and methane (or coal bed methane) as raw materials to produce carbon disulfide has the characteristics of good working conditions, high labor productivity, small equipment footprint, and high degree of automati...
