Heavy aromatic naphtha

Generally, the primary solvent is heavy aromatic naphtha (solvent naphtha, HAN) at 60 to 85% [e.g., Aromatic Solvent 110 or 150 (Texaco)]. 

This gave me an idea. Suppose we injected a liquid spray into the front end of the compressor (we eventually used a heavy aromatic naphtha, obtained from a local refinery). This could prevent the deposits from sticking to the spinning wheels. We tried it, and it worked. Rotor fouling and the consequent vibrations, and loss of capacity, became far less frequent. 

Measure 24.5 mL of solvent (i.e., heavy aromatic naphtha) into a 30-mL bottle.

Kerosene, a heavy aromatic naphtha, or petroleum products with a high aromatic content such as Amsco G , Solvesso 100 , etc., have been used as diluents. A small proportion of a long chain alcohol such as tridecanol, or nonanol, is sometimes added also, to increase the solubility, in the case of amine solvents. It is also claimed to improve aqueous-solvent phase separation. 0 T M amine and 2 3 per cent alcohol are typical concentrations.
