MONOETHYLENE GLYCOL (MEG) MEG Purity 99.8 % wt. min Color [Pt-co ] 5 max DEG 0.08 % wt. max Water 0.08 % wt. max Specific gravity (20/20 ◦C) 1.1151-1.1156 Boiling range at 0.1013 MPA 5% Vol. Min 196 ◦C 95% Vol. Max 199 ◦C Pyhsical Spec: Transparent Liquid, colorless Introduction Monoethylene glycol (MEG) is an odorless, colorless, clear and viscose liquid with a sweet taste, which is produced from the reaction between water and ethylene oxide. It is miscible with water, alcohols, and many organic compounds, and has the chemical formula of C2H6O2. General Applications MEG has numerous applications for manufacture of various products including automotive antifreeze and coolants, resins, deicing fluids, heat transfer fluids, leather, paper, textile fibers, water-based adhesives, sturdy polyethylene terephthalate drink and food containers, latex paints and asphalt emulsions and electrolytic capacitors.

The small gem salt is in the form of cubic crystals, white in color, with a salty taste and in different sizes. After the extraction and crushing process, the white crystals are carefully packaged, in closed, clean spaces. The assortment is used in the chemical industry, tannery, wood industry, textile industry, varnishes, and paints, etc. In industry, sodium chloride is considered the most important inorganic raw material. It is the basic substance of an industrial branch, which processes it to obtain sodium, chlorine, hydrochloric acid, sodium hydroxide, sodium carbonate, etc. At the same time, NaCl is used in the industry of varnishes, paints, paper, plastics, textiles, and others. In the metallurgical industry, it is used as a reducer, and in electronics, it is used in the manufacture of sodium vapor lamps. NaCl is also used in the organic chemical industry and in the pharmaceutical industry.

Condensate polishing During the production process of basic organic chemicals, very often condensates occur as byproducts, which have to be treated before dumping or recycling into production process. The condensate occurring at the product process of caprolactame contents for example ammonium sulfate and caprolactame. The loss of these products instead of recycling would not only mean a reduction of the process recovery, but also very high costs for waste water treatment. These condensates can be concentrated by a reverse osmosis plant. Because of the high salt retention rate of the reverse osmosis membrane, nearly all contents of the condensate are separated and can be brought back to the production cycle. The filtered permeate can be dumped into the municipal waste water system without hesitation. In some cases, the recirculation of the separated contents is not appropriated. In this context, reverse osmosis helps reducing the volume of the accruing condensate. The remaining conden
