Abstract

The invention relates to the field of alkylation assorted waste acid recycling devices in the petroleum refining process and in particular relates to a system for solving ultrahigh gas temperature of a dynamic wave furnace of a waste acid recycling device. The system comprises a dynamic wave gas-liquid separator, a filler washing tower and an electric defogger which are connected through a pipeline; the system is characterized in that furnace gas firstly enter a dynamic wave exchange column; the dynamic wave exchange column is connected with one or more reversed injection pipes; a nozzle control valve is arranged on each reversed injection pipe and used for controlling the pressure of the reversed injection pipe; the reversed injection pipes are connected with the dynamic wave gas-liquid separator through a dynamic wave dilute acid pump; the furnace gas enters the dynamic wave gas-liquid separator and carries out gas-liquid separation, then the furnace gas enters the filler washing tower to be washed and cooled, finally the furnace gas enters the electric defogger and removes the residual acid fog. The system is capable of reducing the temperature of a furnace gas outlet of a dynamic wave scrubber, facilitating long-period and safe operation of the device, improving the treatment capacity of the device, reducing the dilute acid treatment capacity and reducing sewage treatment load and cost.

Description

technical field

[0001] The invention relates to the field of a waste acid recovery device for alkylation in the petroleum refining process, in particular to a system for solving the problem of excessively high temperature of the power wave furnace gas of the waste acid recovery device. Background technique

[0002] Sulfuric acid alkylation unit is currently used as the main means of producing high-grade clean gasoline (blending component oil). During the production process of this unit, 80-90kg of waste sulfuric acid with a concentration of 85-90% will be produced for every 1 ton of product produced. , this waste sulfuric acid contains 8-4% organic matter and water in addition to sulfuric acid. The waste acid is a colloidal liquid with high viscosity. Odor, difficult to deal with, very serious to ecological environment pollution. The waste acid recovery unit is currently the only supporting industrial unit for processing waste sulfuric acid from alkylation, and whether it c...
