HOMOGENIZER

Homogenizers are used to modify the physical properties of a liquid or mixture, in our case slurry or SLES paste, by creating emulsions or dispersions.

The homogenization process utilizes a combination of force of high pressure and mechanical properties of a special mixing pump head at high velocity to obtain reduced size particles and globules, resulting in more uniform and consistent mixture of products.

SULPHONATION
REACTOR

The reactor is the heart of any sulphonation process.
By sulphonation, the industry identifies a set of processes based on reaction between a sulphur trioxide stream in air and an organic base. A large number of end products may be manufactured for use in detergent, toiletry and cosmetic industry.
The largest applications are for production of sulphonated alkylbenzene, for sulphonation of fatty alcohols, the latter in the alcohol form or extended with a 2-moles or 3-moles ethoxylated tail, or for sulphonation of alpha olefins.

Reaction takes place in a multi-tube reactor where the sulphur trioxide stream and the organic are conveyed in co-current. In each tube, a thin film of liquid falls down along the tube inner surface.
The gaseous stream runs along the tube in contact with the organic as necessary to react almost all the sulphur trioxide with the organic base.

To obtain a high quality product, vital features are the formation of the film by experienced calibration, the uniform and homogeneous falling rate in the tubes and the contact time SO3/organic to avoid early contact between the two reacting chemicals.
These features require high accuracy in the machining and in the construction, as well as a step-by-step approach to the manufacturing process, whereby each piece of the reactor is subject to accurate dimensional and constructional appraisal before green light be given for the progress of the construction.
The quality of the product is specified under a set of parameters, linked to the unreacted organic, to the formation of undesired side reaction products, such as sulphuric acid, and to colour.
These deviations from the performance are however caused more often by insufficient process control than by the reactor itself.
In general, a well constructed and calibrated reactor is the last factor causing a trouble in a troublesome sulphonation process.

The reaction develops heat that has to be removed to protect the integrity of the process and to limit the temperature of the product.
At this aim, the tube bundle is enclosed in a stainless steel envelope, behaving as a shell in a heat exchanger. The shell is full of cooling water held in circulation by a dedicated pump. The circulation is maintained at different rates in different segments of the shell in order to match the heat removal requirement along the reaction tubes. A well controlled temperature profile along the reaction path is obtained by a good reactor shell segmental control.

 

VERTICAL
GRANULATOR

The No Tower Granulator (shortly NTG) is an equipment able to manufacture wet granulated product from powdered raw materials fed into the granulator along with set amount of liquids, normally water solutions.

Specially designed conditions must be met in order to allow for the formation of granules.  Such conditions are: the correct balance of powdered and liquid raw materials, the turbulent effect of an excess air flow inside the granulation chamber  and the agglomeration  effect given by specific  mechanical elements in the reaction room.

Compressed air is used to keep the flexible granulation chamber at a sustainable processing condition and to provide for atomization of the liquid injections.

A friendly Control Panel enables the operator to control the process from local or remote station. All production parameters such as motor rotation speed, liquid and powdered raw material intakes shall be controlled by a multipoint control  system, able to allow the operator for provide timely and efficient  adjustment should any upset occur.

The granulator is built at variable geometry by use of deformable materials in order to avoid any sticking of wet materials on the wall of the chamber. The key element are the deformable tubular chamber and the central shaft, driven by an electrical motor at variable speed. The shaftis provided with bolted in rotating devices at variable geometry. Outside the reaction chamber a set of 48 roller keeps the tubular chamber under flexible motion.

VIBRATING
SIEVE

The Marsina Vibrating Sieve is a high capacity industrial vibratory sieve machine . 

The Equipment receives the produced detergent powder and,through a net, it allows to separate the product with standard glanulometry from lumps. 

The Vibrating Sieve is equipped with two vibrating motors ,with adjustable position that make it possible to optimize the amplitude of vibration. 

This unique Vibrating Sieve offers a simple and effective design that does not require high maintenance .
