Abstract
The invention discloses a technique for preparing hydrogen chloride and recovering steam by using a synthesis method, and the technique is implemented mainly by using a tail-gas absorption tower, a block absorber, a combustor-membrane absorption tower assembled body, a circulating pump and a gas-water separator which are sequentially connected by pipelines and integrated. The technique has the advantages of reasonable process, simple operation, high product purity, and can recover a large quantity of steam, therefore, the technique is an ideal technique for preparing hydrogen chloride.
Description
Affiliated technical field
The present invention relates to a kind of synthetic technology of preparing of Chemicals, particularly a kind of synthesis method prepares the technology of hydrogenchloride and recovered steam, is suitable for the synthetic preparation of chemical industry hydrogenchloride.
Background technology
At present, the production technology of hydrogenchloride still can not be produced the pure hydrogenchloride of preparation also under study for action.
Summary of the invention
Problem to be solved by this invention is, overcomes the deficiencies in the prior art, provides a kind of synthesis method to prepare the technology of hydrogenchloride and recovered steam.This technology not only technology is reasonable, and is simple to operate, product hydrogenchloride purity height, and recovered steam, and solved problem of environmental pollution.
The technical solution used in the present invention is: tail gas absorber, piece formula resorber, combustion chamber and membrane absorber assembly, recycle pump, air water separator is linked in sequence by connection line, general assembly one and forming.When using the technology of the present invention, raw hydrogen and chlorine are joined the combustion chambers burn reaction, absorb through membrane absorber and remove impurity, hydrogen chloride gas enters piece formula resorber and handles, and high-purity hydrogenchloride product is produced in preparation.In the preparation process, excess steam is handled through the connection line water separator that degass, recovered steam, and tail gas goes tail gas absorber to handle through connection line, environment protection emission and utilization again.
The invention has the beneficial effects as follows that technology is reasonable, simple to operate, high-purity hydrogenchloride product is produced in preparation, and recovered steam, and has solved problem of environmental pollution.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present invention.
Accompanying drawing number is: 1, tail gas absorber, 2, the combustion chamber, 3, air water separator, 4, recycle pump, 5, membrane absorber, 6, piece formula resorber, 7, connection line.
Embodiment
With reference to Fig. 1, tail gas absorber 1, piece formula resorber 6, combustion chamber 2 and membrane absorber 5 assemblies, recycle pump 4, air water separator 3 is linked in sequence by connection line 7, general assembly one and forming.When using the technology of the present invention, raw hydrogen and chlorine are joined combustion chamber 2 combustion reactionss, absorb through membrane absorber 5 and remove impurity, hydrogen chloride gas enters piece formula resorber 6 and handles, and high-purity hydrogenchloride product is produced in preparation.In the preparation process, excess steam is handled through degas water separator 3 of connection line 7, recovered steam, and tail gas goes tail gas absorber 1 to handle through connection line 7, environment protection emission and utilization again.
Synthesis method prepares the technology of hydrogenchloride and recovered steam, and hydrogen burns in chlorine and generates the method for hydrogenchloride, in order to reclaim the heat byproduct steam.Combustion chamber 2 is with heat-resisting impermeable graphite manufacturing; but produce for strengthening; protection combustion chamber 2 is unlikely overheated; must be cooled off with water jacket; can reclaim heat by the warm water state, recovered steam, the recyclable pressure of every production 1t hydrogen chloride gas is the steam 750kg of 400kPa (gauge pressure); when daily output hydrogenchloride (100%) surpassed 15t, the vapor recovery facility expense that increases can reclaim in 18 months.
Claims (1)
1. a synthesis method prepares the technology of hydrogenchloride and recovered steam, it is characterized in that: tail gas absorber, piece formula resorber, combustion chamber and membrane absorber assembly, recycle pump, air water separator is linked in sequence by connection line, general assembly one and forming.
