With Binacchi you select a trustworthy
partner, able to be at
your side for many years.
Binacchi sells solutions and not simply plants: we are able to satisfy
your requests with professionality, customizing well proven technologies
to your needs.
There are two main processes to obtain soap: one is using oils and fats
as raw materials and the other utilizes fatty acids. The selection of the
most suitable solution depends on many technical and economic factors and
should be done together with Binacchi.
SOAP AND GLYCERINE
PRODUCTION STARTING FROM OILS AND FATS The most used oils and
fats to produce soap are animal fats (typically beef
tallow) and/or vegetable oils (palm oil, palm stearin,
palm kernel oil, coconut oil) and caustic soda NaOH. To produce soap with normal trading standards, oils and fats have to
be bleached or RBD (Refined,Bleached, Deodorized). The saponification reaction produces also glycerine as by-product.
A Saponification Plant transforms
Oils / Fats with Caustic soda into Soap and Glycerine. The soap produced
is liquid, hot and with a high level of moisture: it must be therefore
dried in the next Soap Dryer that
produces noodles of white soap.
The glycerine produced
by the saponification is diluted and contains various impurities
(spent lyes). Spent lyes will be refined, concentrated and
distilled in three subsequent glycerine plants (Purification, Concentration, Distillation)
to obtain pharmaceutical/food grade glycerine.
VIA FATTY ACIDS The alternative route
to soap involves a simple neutralization of fatty acids.
However the main raw materials are again oils and fats that
are first transformed into fatty acids and glycerine by a Splitting
Plant. Fatty acids are
then distilled to
obtain the necessary purity.
In this case the Saponification
Plant is very simple
but glycerine is more diluted (sweet waters). Sweet waters
will be processed in three subsequent glycerine
Also in this
case the soap produced is liquid and with high
moisture therefore a Soap
Dryer is necessary.
