The advantage of the batch column is reducing the number of cuts from 2 to 1 and reducing the reflux ratio from 3 to 2 to save time and money. The NaOH used in excess can be reduced from 8% to 1%. The reduction of NaOH allows cost savings for both the NaOH and the H 2 SO 4.he advantage of the batch column is reducing the number of cuts from 2 to 1 and reducing the reflux ratio from 3 to 2 to save time and money.

Lymphatic filariasis (referred to as LF and also known as elephantiasis) is a mosquito-borne disease that is caused by parasitic filarial nematodes. Though infection usually is acquired in childhood, the grotesquely disfiguring effects of LF is greatest in adults.hen a mosquito with infective stage larvae bites a person, parasites enter the body and migrate to the lymphatic vessels. In the lymphatic system, the larvae develop into adult worms. Infection causes improper functioning of the lymph system, which leads to fluid build-up and swelling (lymphedema).
