Synthetic Detergents

Soaps, detergents, emulsions, moisture and penetrating agents are active agents of modern surface. Detergents are a complex mixture of many substances that increase the cleaning effect of water on solid objects. Detergents vary in their composition, depending on the desired cleaning effect. Detergents are used for bathing, laundry, cleaning of hard surfaces and specialized industrial cleaning. The various types of detergents contain ingredients such as surfactants that decrease surface tension of water. Another type of ingredient used in this production include reinforcing agents, inorganic salts or alkali that enhance the cleaning effect of the surfactants. Detergents also contain auxiliary agents that increase the performance characteristics of materials.

The composition of improved detergents is increasing due to the conditions of their environment. Some synthetic detergents cause water pollution because their surface active agents do not destroy the bacteria in the soil or plants in wastewater treatment. Have been developed and standardized tests to establish the requirement of many biodegradable detergents.

Homemade soaps detergents dominated the market for many years. However, many developing countries still use home-grown soaps. In most developed countries, most recently, non-soap detergents surfactants have been developed and have replaced homemade soaps in the world market. This situation changed with the rise in living standards makes the establishment of this plant in a safe and profitable investment.

Process Description:

The sulfated and neutralized section is designed to allow the raw material, alkylbenzene, oleum (fuming sulfuric acid), caustic soda solution and diluted water tanks to be contained in food, respectively, and raw materials are supplied through a dosing machine, which contains six-piston displacement pump, into the reaction containers.

The section of pipe circulation sulfatide, a container of reaction, and a heat exchanger. The dosing machine (pumps proportional) alkyl sends through the pipe circulation to the reaction container. The sulfating agent (sulfuric acid), which is supplied by its respective volume meter is also transported to the reaction container. The mixture to be sulfated, equal to the amount of reaction agents, are provided and passed continuously by a digestion system where the reaction is complete. The recirculation system temperature is controlled by a valve adjustment of cold water.

This acidic mixture passes from the digestive system into the system of adulteration. Adulteration system contains a reaction container, a heat exchanger and connecting piping. Diluted water, which is supplied from its respective bomb, is introduced into the reaction container. The temperature in the tamper circuit is controlled by a valve adjustment of cold water.

The diluted acid mixture enters the separation system where any leak acid is separated in layers. This separation is controlled by an interface level control, for example, to control the separation of the surface in two layers. Sulfated acid emerge to the top separator and enters the neutralization circuit consisting of a reaction container, a heat exchanger and circulation pipes to transfer the mixture to the pH adjustment tank. The caustic solution is pumped into the reaction container. Sulfated acid is transported to its storage tank and is then pumped into the reaction container. The temperature of this system is controlled by adjusting valves cold water. The pH adjustment tank causes the neutralized product having a uniform composition and homogeneous. The neutralized product is controlled by a continuous pH meter through electrodes placed in the fluid chamber and the pH indicator.

The section on preparing the paste is designed to allow the product neutralized (sodium sulfate) and additional agents (such as sodium triphosphate, sodium silicate, sodium sulphate, CMC, polish, etc..) Are mixed by a clutch at a low speed electric stirrer. The mixed paste is converted into a smooth paste through a colloid mill. Then this paste is passed through filters to remove solid impurities. After passing through the filters, the pulp is transported to its storage tank.

Once the spray tower is ready, the dough is transported to the spray nozzles (placed in the top of the tower spray) through a high pressure triplex pump. Bras, tanks, filters and pipes are heated by a steam device. The engines and the temperature of the process are handled by a central control panel.

The drying section consists of one spray tower, a generator of hot air oven, and a collector cyclone.

The oven using hot air generated from burning oil burning light (or a mixture of diesel and light oil) Hot air is blown and circulated in the spray tower using a blower, located next to the oven.

Detergent paste is sent to the tower and scattered spray from the injectors cutting off the flow of hot air to keep small volumes in tablet form. Then the paste is dried gently and descends into hollowed-out devices before reaching the outlet pipe of the spray tower.

After passing through the spray tower, hot air is released into the cyclone collector, which separates the detergent into a fine powder after it passes through hot air duct and is discharged into an open area.

As the dry powder discharged from the spray tower, is still hot then it is cooled in a pneumatic conveying duct. Then the cold air is separated in a separation chamber and stored in tanks.

Powdered detergent descend on a vibrating screen, separating the fine and coarse dust and going into an appliance where continuous scented perfume is sprayed from the nozzles, then be transported to the packing section.

Detergent powder is sent through a conveyor to the automatic weighing and packaging that is coupled with a continuous sealing machine for sealing the product in plastic bags. Once the bags are sealed, the products are transported to the warehouse for further marketing.
