Liquid -Liquid Extraction
Liquid-liquid-extraction is a separation technology that is based on the distribution of one or more components between two immiscible or almost immiscible liquids and is one of the most important separation/purification techniques widely used in process industries. Extraction finds it is most suitable application when the material to be separated is non-volatile or heat sensitive and when it is not possible to separate by distillation or evaporation.
We have expertise and offered LLE systems on turn-key basis for below applications:
MDC – Methanol, THF – Hexane, Acetone – Methanol
We can Design and/or supply complete absorption systems mounted on skids or otherwise. The equipments involved are wet scrubbers, ventury scrubbers, packed columns, blowers etc. The materials can be Stainless Steels, PP, FRP, HDPE etc.
We have so far supplied systems for the removal of ammonia, sulfur dioxide, hydrogen sulfide, and ammines and met the local regulatory norms.
We can handle:
- Physical or Reactive absorption.
- Desorption can be by means of steam or air.
- Sensitivity studies to locate the optimum solvent rate.
- Column internals can be tray or packed.
- Compact/Skid mounted system designs for small capacities.
- Complete automation using PLC/ DCS.
- Good experience for contaminants like ammonia, NOx, So2, H2S
Stripping is a physical separation process where one or more components are removed from a liquid stream by a vapor stream. In industrial applications the liquid and vapor streams can have co-current or countercurrent flows. Stripping is usually carried out in either a packed or tray column.
Mixing & Reaction
We offer innovative solutions and quality equipment for static mixing, heat exchange, reaction technology. ChemDist has unique design & manufacturing facility for reactors & mixers (Static & Agitated)
The excess methanol is recovered from the bio diesel, glycerine, and fatty matter, dried and reused in the two-step transesterification reaction.
Glycerine generated in the two-step trans-esterification reaction is recovered and neutralized. The crude glycerine contains greater than the maximum 0.01 percent salts allowed in technical grades and is less than 99 percent pure. The salts are formed from the reaction of the caustic and acid used in most trans-esterification processes. The salts are removed when the glycerine is distilled or refined to a technical grade or higher quality.
