Development of Technology & Production of Crystallized fine Ammonium perchlorate.

Development of Technology & Production of Crystallized fine Ammonium perchlorate.

Project Description

The re-crystallization technology of fine AP is still in R & D stage and is pursued by select countries and has not been reported well in the open domain. Presently, a solvent / anti-solvent re-crystallization process has been established for manufacture of fine AP (10 ± 2 μm) and scaled up to 5-10 kg/batch level. However, for very high burn rate propellant, the required particle size range of fine AP is 6 ±1 μm. Therefore, it is essential to develop process for manufacturing crystalline fine AP (6 ± 1 μm) for application in very high burn rate propellants and to minimize experimentation before processing of motor

Feasibility Studies for each project shall be carried out with the involvement of all important stakeholders (Industry, Subject Experts, Industry Associations, etc.). The aim of this study is to identify the projects, which can be undertaken.

Feasibility study includes preliminary assessment of capability of industry to undertake the project, estimated cost and time for development, estimated cost of the component bearing the technology, etc. 

Formulation of Specifications

Based on the feasibility study, Qualitative and Quantitative specifications specifying the key parameters of the required technology will be drafted.  

Issue of Expression of Interest (EoI) and soliciting response

Project requirement will be posted on web-portal for soliciting EoI responses through online Mode.

EoI will consist of brief technical requirement, all evaluation criteria, sub-criteria, etc including respective weight-ages accorded to each of them for assessing responses from EoI recipients.

Industry shall have the choice to respond either in their individual capacity as EoI recipients or as an AoP (i.e. Consortium) of Indian Companies/ Organization/Academia.

Selection of Development Agency

Assessment of EoI responses will be undertaken as per shared criteria. Evaluation criteria relates to the indigenous research, design and development capabilities including past experience, other relevant parameters and performance of EoI recipients as may be required. In case of AoP i.e. consortium, the assessment shall be carried out with specific reference only to the roles and responsibilities of Individual members as mentioned in their AoP Agreements.

Development Agency shall be required to submit Detailed Project Requirement (DPR) including Cost Estimates against the EOI. DPR shall be examined with specific reference to project milestones against the evaluation criteria.

An interaction with the startup if deemed necessary will be carried out at the time of evaluation.

Development Agency (ies) selected post the examination of their DPRs will be issued a Project Sanction Order along with an Agreement.

Upon signing the Agreement, the successful applicant will be issued a grant letter.
