Abstract
The invention provides for a process and apparatus for preparing a soap concentrate, including: (a) introducing feed components to a first feeding zone; (b) first reacting in a first reacting zone; (c) first venting in a first venting zone; and (d) cooling in a cooling zone. The process may further include, after (c) and before (d): (i) continued reacting in a continued reacting zone; and (ii) second venting in a second venting zone. The invention also provides for a process and apparatus for preparing a lubricating composition comprising: (aa) introducing a soap concentrate and a base oil to a lubricating composition feeding zone; (bb) dispersing the soap concentrate in a lubricating composition dispersing zone; (cc) mixing the soap concentrate and the base oil in a lubricating composition mixing zone; and (dd) cooling in a lubricating composition cooling zone.
