Waste chlorinated hydrocarbons are burnt in excess O2 in special burners; the residual organic matter is additionally burnt in an after-burning chamber; the combustion gases are used for heating a boiler; HCl is absorbed from the cooled gas mixt. by means of acid-resistant refractory stones; HCl is then eluted in the form of azeotropic mixt. with water using steam from the boiler. Thus combustion heat is partly utilised, and HCl is recovered. There is no excessive corrosion of the appts.

Verfahren zum Reinigen von Abgasen

FOAMED HIGH VISCOSITY AQUEOUS INORGANIC ACID SOLUTIONS

Method of purification of hydrogen chloride

Hydrogen chloride is freed of water vapour and relatively high boiling gaseous contaminants, e.g. chlorine, hydrogen fluoride, by compressing and cooling the feed gas to condense said contaminants which are then separated by mechanical means or by absorption, following which the partially purified gas is compressed at 7 above its liquefaction pressure and fed at about 30 DEG C. to a fractionating column 8 from the head of which purified hydrogen chloride is withdrawn as product part of which is condensed at 15 and used as reflux whilst the bottoms are withdrawn continuously. The latter may contain chlorine which is vaporized in an evaporator. In the event of chlorine being the only contaminant in the feed mixture, the preliminaty cooling, condensation and separation of the high boiling impurities is dispensed with. Product hydrogen chloride gas may be condensed and fed to a further column for the separation of permanent gases.

Method of organochlorine compounds removal from oil

FIELD: oil, gas and coke-chemical industries. SUBSTANCE: invention relates to oil purification from undesirable components, namely removal of organochlorine compounds (OCC) residues. Process consists in desorption of OCC from oil with inert gas, where nitrogen is used as gas. Steam-gas mixture formed during desorption consists of inert gas and hydrocarbon vapours and is fed into an absorber where the OCC is removed from the vapour-gas mixture by a selective absorber. Steam-gas mixture thus depleted in the OCC is directed back into the desorber for repeated OCC desorption from oil. Peculiar feature of the process is maintaining constant values of hydrocarbon vapours circulating in gaseous phase at outlet of desorber and outlet from absorber. Selective absorber is presented by using an absorbent which is not miscible with light hydrocarbons and is selected from methylpyrrolidone, glycols and water-glycol absorbents containing an alkaline reagent. EFFECT: invention enables to reduce heat costs for evaporation and condensation of light oil components. 3 cl, 1 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 735 843 C1 (51) МПК B01D 53/74 (2006.01) C01B 7/01 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (52) СПК B01D 53/74 (2020.08); C01B 7/01 (2020.08) (21)(22) Заявка: 2019133800, 14.10.2019 (24) Дата начала отсчета срока действия патента: (73) Патентообладатель(и): Общество с Ограниченной Ответственностью "ДИСТИЛИУМ" (RU) Дата регистрации: 09.11.2020 (45) Опубликовано: 09.11.2020 Бюл. № 31 2 7 3 5 8 4 3 R U (54) Способ удаления хлорорганических соединений из нефти (57) Реферат: Изобретение относится к области очистки поддержание постоянных значений количества нефти от нежелательных компонентов, а именно паров углеводородов, циркулирующих в газовой удаление остатков хлорорганических соединений фазе на выходе из десорбера и выходе из (ХОС).

Method for removing volatile components from a high viscosity liquid by using rotation pack bed

A high viscosity liquid is fed into a rotation pack bed at a position with a distance far enough from a rotation axis, creating a centrifugal force exerted on the high viscosity liquid overwhelming a drag thereof, so that it can flow radially through the rotation pack bed. A high pressure gas is introduced into the rotation pack bed peripherally and/or a suction force source is connected to a position near the rotation axis, so that a volatile component contained in the high viscosity fluid is entrained in the gas counter currently flowing through the rotation pack bed and withdrawn from the position near the rotation axis, or the volatile component exits from the position near the rotation axis in gas phase, and thus the volatile component is removed from the high viscosity liquid. A second fluid can also be fed into the rotation pack bed to react with the high viscosity liquid, so that a reaction product is formed, and a volatile side product is removed at the same time.
