Sodium Chloride

Sodium Chloride

Calcium chloride has many uses in industry and differs from country to country due to existing industries. In Iran, calcium chloride consumption is highest for drilling of oil wells while in countries such as USA and Canada the highest consumption of this material is controlled by And there was dust and melting snow and ice.

Applications of Calcium Chloride

Calcium chloride has many applications in various industries. Here are some of them

As an ice and snow thawer (because of the harmful effects of sodium chloride on plants and the better efficiency of calcium chloride at very low temperatures, calcium chloride is preferably used for this purpose.
As an additive to liquids, complement the oil wells to increase density
Consolidate finished oil wells with cement for concrete acceleration
Addition to drilling mud to reduce petroleum rock swelling
Use of highway infrastructure that stabilizes the road and its soil sides by maintaining moisture and thereby increasing soil compaction
Prevent dust formation by absorbing air moisture
Control snow and ice on the surface of the passages with melting snow and ice

Lime production and purification process

First, live lime enters the factory lime storage silos with a purity of more than 5%, and then the live lime is introduced into the rotary reactor (Slaker) with the required amount of silo feeder. In this reactor, calcium oxide reacts with brackish water and lime is produced.

Purification of calcium chloride solution and production of impure magnesium hydroxide

The final brine, received from the K4 pool overflow and transferred to the storage tank at the plant, reacts in a separate reactor with the lime produced in the previous step, during which the reaction produces pure calcium chloride and impure magnesium hydroxide. The overflow of the reaction in the reactor enters the ticker to precipitate magnesium hydroxide, then the bottom of the ticker enters the filter and at this stage magnesium hydroxide is produced as a cake at 2% moisture. The filtrate filter solution, which is pure calcium chloride, also enters the condensation portion.

Concentration of calcium chloride solution

The purified calcium chloride solution enters the evaporator after passing through two scrubbers and absorbs the dust produced by the drive unit and, after heat exchange, part of the water vapor after heat exchange with the steam sent from the boiler. In order to achieve a suitable concentration, the concentrated solution of calcium chloride is sent from the lower part of the evaporator to the top of the evaporator and part of the solution which is concentrated is sent to the spray drive for drying.

Drying of calcium chloride solution and product packing without water

The concentrated solution of calcium chloride is sent to the spray drive. With the heat generated by the fan and the air blown by the fan, the water in the evaporation solution and the aqueous calcium chloride product are powdered by a screw converter equipped with a product cooling system after packing into the 1 and 2 kg or 2 kg bags. It becomes toned.
