STATEMENT OF WORK

Large Scale Calorimeter 25 October 2018

1.0 BACKGROUND

The Energetic Materials Research and Processing department of the Naval Air Warfare Center Weapons Division (NAWCWD) requires an update to the current chemical pilot plant in order to improve process safety and increase the scope of NAWCWD’s capabilities to produce fine chemicals and explosives. The laboratory update will provide NAWCWD with the capability to safely support the warfighter by making energetic chemicals as needed. This includes the ability to transition research discoveries from material readiness level 1 through material readiness level 8/9.

1.1 Scope

This requirement is for modern reaction calorimeters which are used by industry to both improve process efficiency and process safety. These devices are routinely used by industry to map chemical kinetics. This is done to both improve process yields and safety. The same devices map heat flow in chemical reactions. While this data is useful for improving chemical processes, it is vital for calculating safety margins. The proposed solution will provide reaction calorimetry capability at the sub-pilot scale.

2.0 APPLICABLE DOCUMENTS

System Engineering Plan: Chemical Pilot Plant Modernization CIP FY2019, Revision A, 12 September 2018.

3.0 REQUIREMENTS

The contractor shall provide an automated reaction calorimeter, meeting all the requirements and specifications detailed in the following sections. The system shall be compatible with certain equipment previously purchased by NAWCWD, as specified in the following sections; that equipment includes a Mettler-Toledo (MT) Focused Beam Reflectance Measurement Probe (FBRM) and a MT ParticleView Microscope (PVM) probe.

3.1 Automated Reactor

The contractor shall provide, as part of the automated reaction calorimeter system, an automated batch chemical reactor. This reactor shall be of a design and configuration to react reagents, and provide heat transfer to process fluid.

3.1.1 Capacity

The reactor shall have a nominal volume of 18 L. The reactor shall also include an agitator and motor.

3.1.2 Materials of Construction

The materials of construction for wetted surfaces should be compatible with reagents and solvents common to the direct nitration of polyols; including but not limited to: concentrated sulfuric acid, concentrated nitric acid, white fuming nitric acid, and oleum.

The materials of construction for all other non-wetted surfaces should be reasonable and prudent to the intent and scope of this SOW, and in keeping with industry standards.

3.1.3 Operating Conditions and Boundaries

The process side of the reactor system should be capable of full and unhindered operation within a reaction mixture temperature range of -5°C to 120°C, at ambient pressure.

3.1.4 Reaction Calorimetry

The system shall be capable of deriving from measurement the heat of reaction, in both adiabatic and isothermal modes.

3.1.5 Instrumentation

The reactor shall be configured for and capable of measuring the temperature and pH of the reactant mixture. The reactor vessel should be capable of physical integrating the MT FBRM and PVM probes.

3.1.6 Liquid Dosing Pumps

The contractor shall provide a total of two (2) pumps and associated equipment to provide gravimetric dosing of liquids into the reactor. The pumps should be capable of volumetric flowrates adjustable from 1 mL/min to 100 mL/min. The materials of construction for the wetted surfaces of pumps should have good corrosion resistance characteristics for common organic solvents, common inorganic solvents, common halogenated solvents, strong mineral acids, strong and weak bases, and common organic reagents. Where possible and prudent this might include the use of any one or combination of stainless steel (either 316 or 316L), chemical resistant glass, and fluorinated elastomers. The dosing pump system shall be controllable from the control system detailed in later sections.

3.2 Heater-Chiller Unit

The contractor shall provide a heat exchange fluid heater-chiller unit, designed to support the use of the continuous flow reactor for the intended purpose, described in previous sections.

3.3 Control System

3.3.1 Automation

The control system shall be capable of controlling the dosing pump system, described in previous section; to include the ability to start and stop pumping, and adjust the rate of pumping of each pump independently. The control system shall also be capable of controlling the temperature of the heat exchange fluid in both isothermal and adiabatic modes of calorimetry. The rate of agitation must also be controllable.

3.3.2 Control and Integration of FBRM and PVM Probes

The control system shall be capable of integrating and controlling the Mettler-Toledo FBRM and PVM probes.

3.3.3 Remote Operation

The control system must be capable of being physically separated from the rest of the system, i.e. housed in a control room. The control room will be no more than 100 linear feet from the operational room wherein the rest of the system resides. The control system must integrate with the rest of the system via a physical connection, e.g. fiber optical cable or wire, not through radio communication.

3.4 System Integration

The contract shall provide all appropriate fittings, connectors, adapters, cables, hoses, lines, and anything else necessary for the full assembly and integration of the system components.

3.5 Installation and Training

3.5.1 Installation and Start-Up

The contractor shall provide installation of the equipment at NAWCWD, to include an initial start-up of the system. The contractor shall allow NAWCWD personnel to observe the installation.

3.5.2 Testing and Verification

The contractor shall execute an acceptance test procedure, demonstrating and verifying the ability of the installed system to meet all of the aforementioned requirements. The contractor shall allow NAWCWD personnel to observe the testing and verification, and provide a record of the results.

3.5.3 Training

The contractor shall provide on-site training to NAWCWD personnel in the operation of the system.

3.5.4 Documentation

The contractor shall provide all relevant and pertinent documentation for all hardware and software provided.

4.0 Travel

Travel is required for the purposes of training/installation.
