Title: Process and plant for enhancement of conversion performance of gaseous pollutants in industrial waste gases
Inventor: IGHIGEANU DANIEL PAUL
IPC: B01D53/60
Filed: 2010-04-21
Abstract: The invention relates to a process and a plant intended to remove gaseous pollutants from industrial waste gases. According to the invention, the process consists in irradiating waste gases with electron beams, concomitantly with the application of a microwave treatment. According to the invention, the plant comprises an electron accelerator, an enclosure for combined irradiation: accelerated electrons and microwaves, consisting of a gas inlet (1) with three connections, an electron window (2), an enclosure (3) proper , a metal sieve on which a catalyst (4) is placed, a gas discharge funnel (5), a gas mixing and recycling system (6) and a microwave generating and control system (7) consisting of six microwave generators containing magnetrons and filament converters therefor which inject a microwave field into the enclosure (3) and which are controlled by three supply and control modules, each module comprising two supply and control systems for two magnetrons, a system for producing and conditioning the polluting gaseous mixture and a system for analysing the gaseous mixture before and after irradiation.

Title: Process and installation for treatment of spent caustic solutions resulting from installations for pyrolysis gas sweetening
Inventor: OPREA FLORIN
IPC: C02F1/74
Filed: 2012-01-23
Abstract: The invention relates to a process and an installation for treating and removing spent caustic solutions resulting from hydrocarbon pyrolysis gas sweetening. According to the invention, the process consists in treating the caustic solution by successive operations of dilution and neutralization with sulphuric acid up to a pH = 8...9, direct steam heating up to a temperature of 50...90°C, air oxidation for 72...144 h, after which the liquid effluent is discharged into a purification plant or is used in the primary dilution of spent soda. The installation, as claimed by the invention, comprises a tank (V1) operating at atmospheric pressure, a buffer vessel (V2) and a washing and cooling column (C1).
