ABSTRACT:
A process for preparing a solution of a liquid additive in a liquid base wherein the liquid additive tends to gel when mixed with the liquid base at temperatures less than a gelling temperature TGincludes the steps of providing a stream of the liquid base at a temperature TCwhich is greater than ambient temperature and less than the gelling temperature TG; feeding the stream to a mixer having a mixer inlet so as to impart energy to the stream; and adding the liquid additive to the stream downstream of the inlet, whereby the liquid additive mixes with the liquid base and the energy inhibits gelling of the liquid additive.
