The 'rich' absorption oil, now containing NGLs, exits the absorption tower through the bottom. It is now a mixture of absorption oil, propane, butanes, pentanes, and other heavier hydrocarbons. The rich oil is fed into lean oil stills, where the mixture is heated to a temperature above the boiling point of the NGLs, but below that of the oil.

Steam Stripping – Steam Distillation for Cleaning Plant ...

Steam stripping, also known as steam distillation, is an affordable, one-step solution to cleaning volatile organic compounds (VOC) from plant wastewater streams. Typically, wastewater feed streams enter a distillation column at the top and flow downward, while steam enters the column at the bottom and rises.

Absorption of HCl in water. The absorption of hydrogen chloride in water is strongly exothermic ~2100 kJ/kg HCl, which means that the absorption liquid becomes easily warm. High concentrations of HCl in water can be achieved only at temperatures lower than 40°C.In order to keep these low temperatures the removal of absorption energy is necessary.
