Description

В предлагаемом способе регенерации бензола из газов, образующихс  при последующей после сульфировани  операции нейтрализовани  сульфурационной -массы карбонатами, наход щийс  в сульфурационной массе полу св занный бензол освобождаетс  и улетучиваетс  вместе с парами воды и углекислоты; из смеси паров бензол въщеп ют абсорбированием крепкой серной кислотой, которую затем направл ют дл  нового процесса сульфировани .In the proposed method for the regeneration of benzene from gases formed during the subsequent neutralization of the sulfuration mass by carbonates after sulfonation, the semi-bonded benzene in the sulfuration mass is released and evaporates along with the water and carbon dioxide vapors; from the vapor mixture, benzene is increased by absorption with strong sulfuric acid, which is then sent for a new sulfonation process.

На чертеже представлена схема технологического процесса.The drawing shows a flowchart.

Из сульфуратора / готова  сульфурационна  масса пневматически выдавливаетс  в мерник 2, а оттуда самотеком идет в нейтрализатор 3, где происходит ее нейтрализаци  содой. Пары из нейтрализатора идут через ловушку дл  поглощени  воды в сосуд 4 с серной кислотой той же концентрации, что и кислота, примен юща с  дл  сульфировани  бензола. Этот сосуд может быть железным-или чугунным и должен иметь дл  обогрева рубашку или змеевик. Пары из нейтрализатора могут поступать в серную кислоту через барбатер или же орошатьс  подогретой серной кислотой.From the sulphurator / sulphuration unit is prepared, the mass is pneumatically squeezed into the measuring device 2, and from there by gravity goes to the neutralizer 3, where it is neutralized with soda. The vapors from the neutralizer go through a trap to absorb water into vessel 4 with sulfuric acid of the same concentration as the acid used for the sulfonation of benzene. This vessel may be iron or cast iron and must have a jacket or a serpentine for heating. Vapors from the neutralizer can enter sulfuric acid through the Barbate or be irrigated with heated sulfuric acid.

Вс  система находитс  под выт жкой (вентил тор или вакуум-насос). Пары, бензола, попада  в крепкую теплую серную кислоту (около 100°), сульфируютс ,, а углекислота - уходит. В сосуде 4 получаетс  сульфурационна  масса, состо ща  из сульфобензола и большого количества свободной серной кислоты. По окончании операции содержимое сосуда 4 передаетс  в сульфуратор /дл  дальнейшего использовани  оставшейс  свободной серной кислоты.The entire system is under a hood (fan or vacuum pump). The vapors, benzene, getting into strong warm sulfuric acid (about 100 °), are sulphurized, and the carbonic acid leaves. Vessel 4 produces a sulfurization mass consisting of sulfobenzene and a large amount of free sulfuric acid. At the end of the operation, the contents of the vessel 4 are transferred to the sulforator / for further use of the remaining free sulfuric acid.

Таким образом, предлагаемый способ регенерации полусв занного бензола не вводит в заводский процесс никаких новых операций.Thus, the proposed method for regenerating semi-bound benzene does not introduce any new operations into the factory process.

Предмет изобретени .The subject matter of the invention.

Способ регенерации бензола из газов,, получающихс  при нейтрализации карбонатами сырого сульфированного бензола , отличающийс  тем что из означенных газов, с применением и без применени  удалени  содержащейс  в них: воды, абсорбируют бензол с помощью крепкой серной кислоты, которую зате№ направл ют дл  нового процесса сульфировани  бензола.The method of regeneration of benzene from gases that are obtained by neutralizing carbonated crude sulfonated benzene, characterized in that from these gases, with and without the removal of the contained in them: water, benzene is absorbed by using strong sulfuric acid, which is used for a new process. benzene sulfonation.
