The plant’s capacity is 126800 MTPY

P205, based on the following param­eters:

■Economical considerations

■   Future plans for Phosphate rock pro­duction in Iran

PLANT’S REQUIRED RESOURCES

In its full capacity, the plant needs:

■  425,000 MTPY phosphate rock.

■   340,000 MPTY sulfuric acid.

■  Anti foam and grain modifiers in small quantities.

■  Utilities, mainly 300,000 MTPY steam, 700,000 MTPY process wa­ter, 23,000,000 MTPY seawater and

20.0.000 kwh electricity.

LICENSE, DESIGNER AND EQUIP­MENT SELECTION

The Wet Process is the most common production method of Phosphoric Acid with concentrations of 52-54% P205 that is used to produce complementary animal feed and fertilizers.

“Prayon, DH, MK, LLFC” technology was chosen among different Wet Proc­ess technologies, based on the following criteria

■   Maximum extraction of P205.

■  Design adaptability for using different Phosphate rocks.

■   Minimum required investment.

■   Minimum consumption of steam.

■  Minimum Pollution of the environment.

Considering the background and experi­ence of different designers and suppliers “SNC LAVALIN EUROPE” was selected as the main contractor to supply License, Basic Engineering and main equipment for the following reasons:

■  Long term and vast experience in this field.

■Licensed in Prayon Technology.

■  Guarantied Conformity of the product with the international standards.

The following equipment which are the most modern and advanced in the in­dustry, have been supplied for the plant:

■  Slurry Filter by “PROFILE- BELGIUM"
