Description
Technical field
The invention belongs to chemical gases and administer technical field, be specifically related to a kind of recovery process of hydrogen sulfide gas.
Background technology
Recycling to hydrogen sulfide gas in Chemical Manufacture, is mainly the claus process of production of sulfur from hydrogen sulfide sulphur and the acid-making process of production of sulfur from hydrogen sulfide acid at present, and technique is more ripe. But in actual production process, often run into key equipment and go wrong or cut off the water suddenly, have a power failure, situation about need to stop in emergency. Existing processing method of stopping in emergency is the in time upper operation of the notice processing of stopping in emergency, then carry out emptying to the hydrogen sulfide gas in system, emptying method is guided to by floss hole by emptying house steward often, light and incinerate a large amount of hydrogen sulfide gas that stop in emergency and produce by igniter, burning produces tobacco, generate sulfur dioxide flue gas and enter in atmosphere, the one, seriously polluted to ring jade tablet, the 2nd, start-stop car causes a large amount of waste of raw materials.
Therefore, there is following defect in existing hydrogen sulfide recovery and processing system: while stopping in emergency without in system hydrogen sulfide gas reclaim device, environmental pollution is serious, its two be directly affect product manufacture cost consumption.
Summary of the invention
The technical problem that while stopping in emergency in order to solve, in system, hydrogen sulfide cannot effectively reclaim, the invention provides a kind of recovery process of hydrogen sulfide gas. Recovery process of the present invention is not externally discharged or is burned hydrogen sulfide gas, and in industrial processes, noxious gas emission is zero, and non-environmental-pollution is opened in docking process and lost without raw material, relatively reduces cost of goods manufactured unit consumption.
For achieving the above object, the present invention adopts following technical scheme:
A kind of recovery process of hydrogen sulfide gas, the hydrogen sulfide gas producing in chemical producing system is connected and sent into hydrogen sulfide treatment device by pipeline, it is characterized in that: in the time that hydrogen sulfide treatment device stops, cut-out hydrogen sulfide enters the pipeline of described treating apparatus, and the production system that produces hydrogen sulfide is stopped; Hydrogen sulfide gas remaining in production system is connected and is entered hydrogen sulfide gas holder by pipeline, in the time that gas holder pressure reaches with production equipment system pressure balance, open hydrogen sulfide compressor, by the hydrogen sulfide gas suction hydrogen sulfide gas holder in production system, until system and device gauge pressure is, stop compressor at 1 o'clock; In the time that hydrogen sulfide treatment device is driven, by hydrogen sulfide compressor, the hydrogen sulfide in gas holder is sent into hydrogen sulfide treatment device and process.
Described hydrogen sulfide treatment device refers to production of sulfur from hydrogen sulfide technique or acid-making process device.
Described hydrogen sulfide gas holder connects nitrogen cabinet, and for hydrogen sulfide gas holder is carried out to gas displacement, normal production guarantees that gas holder is in 100% safe condition.
Preferably, described hydrogen sulfide compressor is sent the hydrogen sulfide in gas holder into hydrogen sulfide treatment device, in the time that the gauge pressure of hydrogen sulfide gas holder reduces to zero, opens the valve of nitrogen cabinet, and the hydrogen sulfide gas in gas holder is replaced. Nitrogen and a small amount of hydrogen sulfide all enter hydrogen sulfide treatment device, have ensured the security of gas holder simultaneously.
Preferably, described stink damp is provided with oxygen concentration detecting instrument cashier's office in a shop, sends warning when oxygen concentration approaches hydrogen sulfide explosion limit, and passes into nitrogen by nitrogen cabinet, thereby reduces oxygen concentration.
Preferably, in hydrogen sulfide gas holder, oxygen concentration is greater than 5%, and oxygen concentration detecting instrument sends warning.
Calculate by the process units of 20,000 tons, while stopping in emergency, discharge the about 600NM of hydrogen sulfide gas3/ time, as the gas of discharge is recycled into sulphur, recyclable 1500 yuan/time. Therefore,, for the process units of 20,000 tons, every parking once can reduce costs the consuming cost of 1500 yuan.
Beneficial effect of the present invention is:
1, recovery process of the present invention is provided with hydrogen sulfide gas holder between the connecting pipe of chemical producing system and hydrogen sulfide treatment device, play cushioning effect, solve the recovery problem to remaining hydrogen sulfide gas in system when prior art is stopped in emergency, externally do not discharge or burn hydrogen sulfide gas, in industrial processes, noxious gas emission is zero, non-environmental-pollution; Meanwhile, open in docking process and lose without hydrogen sulfide, reduce the consuming cost of product.
2, because hydrogen sulfide gas holder connects nitrogen cabinet, can carry out gas displacement to hydrogen sulfide gas holder by nitrogen cabinet, ensure in gas holder without remaining hydrogen sulfide gas, in normal production, guarantee that gas holder, in 100% safe condition, is convenient to the manual operations such as parking checking.
3, be provided with oxygen concentration detecting instrument cashier's office in a shop at stink damp, in the time that oxygen concentration approaches hydrogen sulfide explosion limit, send warning, and pass into nitrogen by nitrogen cabinet, thereby reduce oxygen content, further guaranteed the security of producing.
