Project
Cement Plant Kuwait

The evacuation of bypass dust from the preheater tower and the feeding into the five cement mills belong to the activities of Kuwait Cement Company KCC.

 

Because of the high percentage of chloride contained therein, special attention must always be paid to the characteristics of the bypass dust.

Given the reference projects and impressive expertise, KCC opted for STAG.

The engineering phase is backed by the Geneva-based consulting firm PEG.

Following the supply of the pneumatic and mechanical conveying systems, gravimetric dosing units, a flat bottom silo including all equipment and a discharge screw as well as of a complete compressed air treatment facility with adsorption dryers, STAG was also in charge of the assembly and commissioning of the plant in Kuwait.  

 

The plant is run via a STAG control system.

Bypass dust 3 - 5 µm - 0.6 – 0.7 t/m3 200 °C abrasive
Appropriate Topics
Dense Phase Pipe "DenseFlow"

In conventional conveyances of powdered bulk materials through smooth pipes, the irregularity of the flow rises with the increasing pipe length. This in turn, increases the wear of the system.

Pressure Conveying Vessel

The pressure conveying vessel is used by STAG when it comes to challenging tasks, high conveying rates and long con-veying distances. This pneumatic conveying application using the dense flow method combines energy-optimised conveying processes with perfect operational safety.

Water Treatment Seine Grésillons (GEREG)

In the area of water treatment and sewage sludge recycling, STAG implemented over the past years some pneumatic bulk material conveying and storing projects on behalf of the plant operator “SIAAP” in the Paris region.
