Our Products
Leading Manufacturer, Supplier & Retailer of HCL Concentration and Purification Plant and Liquid Extraction Plant.
Aqueous Hydrochloric acid is a mixture of Hydrochloride and Water. As Hydrochloride is highly soluble in water, Aq, Hydrochloric acid at 25 0c, available in strength up to 30 % Hydrochloric acid Large Quantity of Hydrochloric acid is used in Metal Processing industry, where dilute acid is generated. It is necessary to recycle Hydrochloric acid to cut costs due to neutralization and environment.UD technologies offer solutions for this problem and offer Hydrochloric acid Concentration plants. We choose appropriate technology and Material of Construction depending on capacity Hydrogen chloride/water displays a maximum azeotrope at a boiling temperature of 108.6°C, for a system pressure of 1 bar and an HCl concentration of 20.2wt%.
If the acid concentration is lower than the azeotrope mixture, the acid can be concentrated only up to the azeotrope point. Further concentration needs special procedures.
We have considered the most economical contemporary technology “Azeotropic distillation & Absorption Technology”. This is an economical technology. The azeotrope point is suppressed as best as possible and increases the relative volatility of HCl. The relative volatility may be impacted by the change of the activity coefficients. This is achieved by the addition of a third ingredient, which knocks out water and displays strong hygroscopic properties. Conc. HCL & HCl gas is produced at the head of the Azeotropic distillation and Absorption column depending upon the choice of an appropriate extraction agent. In the column, the extraction agent is diluted with water, which is extracted in a selective fashion from the inflowing mixture. Subsequently, the extractive agent is recycled and concentrated and fed into the Azeotrope Distillation process. Sulphuric acid and aqueous solutions of CaCl2 are appropriate extraction agents for the concentration of hydrochloric acid.
UD Offers different Extraction solutions
Mixer SettlerMixer-settlers, both as stand-alone and as in-column type, are offered for special applications. Due to the pump-mix turbine no additional feed pumps are required in most cases.
Continuous Packed Bed Liquid Liquid ExtractionThe key benefit of a packed column is the high throughput which leads to small column diameters. Together with specially adapted liquid distributors, our structured packing provides the best extraction performance
Agitated Extraction ColumnIn applications with high mass transfer and/or changing physical properties, this is the column of choice. The compartment geometry can be adapted to compensate for changing conditions resulting in a constant high column performance. The main features are the special mixing turbines and the perforated partition plates.
All Items can be coupled with Computers for Control and Data Acquisition through SCADA.
UD Offers Glass Rotating Disc ExtractorsThe Rotating Disc extractor is a continuous, counter-current, liquid-liquid extractor, used for extraction of product or impurities from aqueous or organic streams by extraction with suitable organic solvent or water. The technique with its excellent repeated mixing and settling feature at each stage creates an extraction capability that is equivalent of several washings in a batch kettle. Solvent consumption can be reduced almost to 50% and power consumption to 70% than the batch operation. Simple and non-laborious operation with use of simple automation makes it possible to get consistent results.Used for extraction of product or impurity from bulk drug reaction mass, impurity removal from agrochemical product streams, extraction of product from mass stream in plant extract stream, biochemicals, recovery of product or toxic component from waste water stream
Agitated Extraction is Practically Universally Suitable for all type of Liquid Liuid Extraction.Limiting Condition is minimum density difference 0.05 Kg/M3 between both phases and a not to form Stong tendancy to form stable emulsion in order to allow a smooth agitation
