Product Description
I.Structure And Features
The production is made up with fixed burner, HCL compound part, byproduce steam pass and top furnace cooler. With the merits of compact,small occupation area,runs steadily,high heat energy utilization,operational flexibility high and it can realize automatic control.
The unit consists of synthesis and cooling sections.H2 gas will bind into HCL gas in the synthesis section,then cooling to 45℃ through the cooler,and feed to absorber or other process.
II.Absorption of HCL Gas
The absorber can absorb the HCL gas from synthesis uint, incinerator or other devices.
HCL gas is absorbed by water or weak acid,with model selection based on specific calculations.The temperature will be increased with the reaction of gas and absorbent.The absorption is an exothermic process, so that the absorption device is usually composed of falling film absorber and columns.
The two common mode of absorption are Isothermal absorption and Adiabatic absorption.
Isothermal Absorption
Isothermal absorption is more economical for higher concentrated HCL gases.Therefore a water-cooled falling-film absorber is used for the absorption and cooling of the produced HCL acid.The falling-film heat exchanger can be operated in a co-current or counter-current mode.In a co-current absorption,both liquid and gas are fed at the top of the heat exchanger. The produced acid and the vent gas with unabsorbed HCL leave the equipment at the bottom outlet.This vent gas is scrubbed in a downstream absorption column. The weak acid leaving at the bottom is used ad absorption liquid for the falling film absorber.An appropriate design with trays or packing ensures that the specified emission limits are met.
Adiabatic absorption
Adiabatic absorption is normally used for weak HCL gases
HCL gas is fed through the bottom of colum,while the absorption liquid is fed at the top.Gas and liquid flow are counter-current to ensure optimum absorption.The height,diameter and internals are designed in such a way that the desired acid concentration is abtained and the purity of the vent gas is maximized.The absorption generates a lot of heat the hot acid is cooled by an integral or separate heat exchanger.
III.Technical Features
Three in one type furnace consists of synthesis,cooling and adsorption.The tail gas discharges after absorption by the tail gas column.
Four in one type furnace consists of synthesis,cooling,absorption and tail gas cleaning.The tail gas can be discharged directly.
The common property of above two series is that the HCL absorption is a counter current process.The liquid distributor ensure uniform liquid film districution in the pipeline.
