Since most solvents are imported and account for a large amount of drug currency, so their recycling in a way that can be used in this industry (pharmaceutical pharmacopoeias) is one of the priorities of the country’s pharmaceutical industry. In addition, the environmental requirements in relation to their disposal are very strict and failure to pay attention to this will cause irreparable environmental damage. The company has provided solvent recycling capacity by using multi-purpose distillation towers to separate azotropic and isotropic systems and three-component solvents with very low to relatively high boiling points. It is possible to perform all the above services in “CheMed” Company.
