Bullet APPLICATIONS
Comp Engineering and Exports provides turnkey Detergent Making Plant for the following detergent applications.
The complete detergent powder processing essentially begins from slurry formulation and finishes with the packing of the perfumed spray dried detergent powder. These detergent processing plant are provided on turnkey Basis and are used in :


Applications

  1. Washing Powders (Detergents, Soaps, Surface Active Agents) :
    The free-flowing, non-dusty, non-caking products in bead form are produced in counter-current flow dryers with nozzle atomization is the preferred layout for high-bulk-density detergents. Feeds are homogenized and fine-filtered prior to passing to nozzles operating at high pressure. Hot air from direct-fired air heaters enters at the base of the cylindrical part of the tower with slight rotary motion. The exhaust air is drawn from the top of the tower. Inlet temperatures vary according to product. Up to 400°C (750°F) is used for some detergents, but lower temperatures are used for fine washing agents. Product recovery from the drying tower is high (99%). The fines fraction is usually returned to feed preparation. Open - cycle dryers are normally used, Co-current dryers are used for low - bulk - density detergents.

  2. Soda Products :
    Detergent formulations consist basically of (a) an active ingredient (b) sodium tripolyphosphate, (c) silicates, (d) sodium sulphate. Normally the active ingredients are fatty alcohol sulphates, primary and secondary alkyl sulphonates and alkyl aryl sulphonates. Synthetic detergents are currently based upon linear alkyl benzene sulphonates. Formulations are with variations as decided by each company.

  3. Heavy - Duty Detergents :
    Synthetic detergents are widely used in cleaning of all types and operate successfully with hard water. The coarse powder granules in bead form are free-flowing, non-dusty and readily dissolve in water. Shelf-life is excellent, with no tendency to instability or lumping. The feed can be formulated batchwise or continuously. Comp slurry preparation systems ensures the right preparation technique which improves the quality of the final dried detergent powder. Precise weighing / metering, mixing, homogenizing and de-aeration take place before spray drying. As high a solid content as possible is used (50 - 65%) to give the optimum powder bulk density and best economic use of the spray dryer.

    The product is dried in a counter-current-flow drying tower at inlet temperature 350 - 400°C (660 - 750°F). The dried powder leaves the base of the drying tower and is transported via a conveyor belt to an air lift. During passage on the belt, product dosing is carried out. Dosing materials can be products that would be damaged during spray drying, e.g. lauryl alcohol, enzymes. Bleach alongwith enzymes is also added at this stage. Perfume is added after the following air lift.

  4. Light Duty Detergents
    Light - duty detergents are used less than heavy duty. They find wide application only in dish washing and light household cleaning (janitoring). Light -duty detergents are produced in nozzle towers with either co-current or counter-current flow. Choice depends upon required bulk density. Inlet drying temperatures are also lower, 250 - 275°C (480 - 530°F).

  5. Detergent Allied Products
    Comp also provides state of art powder technology for detergent allied products like Sodium Lauryl Sulphate (SLS), Alfa Olefin Sulphonate (AOS), Optical Brightening Agents (OBA), Linear Alkyl Benzyl Sulphonate (LABSA), Sodium Silicate, Sodium Tri-polyphosphate (STPP)
