Concentration of Weak Sulphuric Acid from 20 % to 70 %
UD Technologies offer sulphuric Acid concentration plants from 20% to 70% .
Sulfuric acid is one of the worlds most widely used chemicals and finds numerous applications as the production of fertilizers, explosives, plastic as e.g. polyurethanes, esterification of intermediates, dyes and also the iron and steel industries.
In most chemical processes contamination and dilution of concentrated sulfuric acid occurs producing huge waste streams of contaminated spent sulfuric acid.
70% Sulphuric acid can be reused .Also Concentration up to 70% , during evaporation, Sulphuric acid vapors evolved is nearly nil.Concentrating sulfuric acid from 20 to 70wt% involves evaporation of large amount of water out of the sulfuric acid. Single- or multi stage natural circulation evaporators, Themosyohon or Forced circulation evaporators in Multi stage are used to minimize the required amount of heating steam. Multi stage evaporators uses vapor arising from previous or next evaporator using boiling point difference and pressure difference.
The number of stages and the type of heating system for each stage are governed by the concentration of the waste acid and the available heating media. Account must also be taken to the behavior of the acid during the concentration process such as the generation of gases possibly leading to foams and the precipitation or evaporation of products present in the waste sulfuric acid.
bromine in nature available in sea water in ppm levels.sea brine-bittern formed in salt farms after removal of salts contains bromine in 2-6 gpl level. highest bromine content available in the dead sea at israel and jorden. bromine is extracted from salt brines by reactive stripping.
bromine recovery from sea bittern
brief process description :
process divides into three steps:
displacement of elemental bromine from sea bittern in oxidation reaction by chlorine
steam stripping of bromine and condensation
purification of bromine to remove chlorine and moisture.
main reaction column is combined reactive stripping column. first, two steps carried out in the same column. step 3 purification involves separate distillation column.design of plant is carried out considering varied bromine content in feed ad varied flow rates. due to this design, it is possible to run the plant in different seasons with consistent purity.
product quality specification:
strictly adheres with indian government standard is 2142
bromine wt%: 99.5%
chlorine- wt % > 0.05% -0.08%
bromine recovery from industrial solutions we design, supply and commissioned the glass plant for is quality bromine from industrial bromide solutiob
aqueous bromide solution is reacted with chlorine gas in reaction or stripping column. the chlorine liberates elemental bromine from the dissolved bromide. this is stripped out by the live steam feed from the bottom of the column.
crude bromine is then distilled to get bromine purity of minimum 99.5%. the solution is not always so simple though, as feeds are often contaminated with organic material from the process. these organic impurities have to be removed by pre-treatment before feeding to the plant.

Diluted Sulphuric Acid is used in chemical industry for Chemical Reactions and in Battery industries, Dilute Sulphuric Acid used of Different concentration. Sometimes two different strength of Sulphuric Acid streams and concentrated Sulphuric acid to have definite concentration of Sulphuric Acid. Dilution of Sulphuric Acid Produces Enormous heat .This heat transferred to Dilute sulphuric acid and eventually reaches more than boiling point in range of 50% or more
Their goal is to obtain diluted sulphuric acid at a required concentration and temperature.
Principles of dilution: The concentrated acid and water are mixed in the dilution unit. This reaction is very exothermic and the acid after dilution has a high temperature. The diluted acid is cooled in a Appropriate Glass and /or graphite heat exchanger considering strength of Dilute Sulphuric Acid
Characteristics: Accurate calculating of the thermal balance, optimized design and selection of the best suitable equipment.SKID enclosing all the equipment for acid dilution, pipe connections, the control of the cooling and security equipment. The user can directly connect the delivery pipes for the concentrated acid, the dilution water and the cooling liquid.
The following equipment, made from anticorrosion materials, can also be supplied separately:
Installation and commissioning
Advantage:
Application: All processes requiring continuous and important quantity of sulphuric acid.
