Description

This is a Turnkey project consisting of design, fabrication, supply, testing and commissioning of a process plant for increasing the ammonium perchlorate yield by recovering AP from Crude Mother Liquor. Ammonium perchlorate is used as a solid propellant for ISRO's launch vehicles.

The process plant consists of:

• Evaporators
• Crystallisers
• Pumps
• Piping
• Structural framework

The entire processing is controlled automatically by PLC.

Construction details

Materials:

• Evaporators: Titanium Gr2
• Crystallisers: SS316L
• Structure: SS 316L

Critical aspects

• Finite element analysis of the structure was carried out to ensure integrity under all loading conditions, including seismic loads.
• Design and routing of piping was carried out for entire plant.
• Control and instrumentation system is integrated in the process to enable remote control of process.
• Stainless teel fabrication for vessels and structures was carried out in isolated stainless steel bay
