National Research Council Canada has a requirement to purchase a High Pressure Heated Stirred Reactor to be delivered to 4250 Wesbrook Mall, Vancouver, BC V6T 1W5.
General Description and Usage The high pressure heated stirred reactor will be used in corrosion and corrosion/erosion studies with various environments that are typical in mining, oil, gas and power generation industries. Some of these environments may be viscous fluids with viscosities of 2000 cp. Given the nature of the studies, the capability of the apparatus to vigorously stir such fluids is important - in fact, the higher the rotation speed that can be achieved, the better it is.
Suspended abrasive particles may be present in the environment. To prevent erosion of the vessel, a liner must be used every time when suspensions are present, hence borosilicate glass or stainless steel liners need to be available. The liner will not prevent the erosion of the internal wetted parts like the thermowell and the stirrer. Therefore these parts must be removable and replaceable by the user.
Corrosion studies involve electrochemistry, hence the need to pass electrical wires through the head and into the vessel. The wires, obviously, need to be insulated from the lid and between them. The wires are low current and low voltage, but need to withstand the most aggressive environments and be compatible with the experiments. Typically, they are bare (non-insulated) and made of gold or platinum. Ideally, the glands used to seal the wires would allow for these wires to be replaced by the user. If non replaceable contacts are to be provided, they must be platinum or gold wires (not plated) and allow spot welded contacts on both ends.
A high pressure liquid pump will be used to bring he vessel at the operating pressure, therefore a high pressure liquid connection with a dip tube is needed on the autoclave's head.
General Construction Some of the environments that will be used during experiments and tests may contain significant amounts of dissolved chlorides and/or sulphides, hence a high temperature corrosion resistant construction material is paramount for the vessel, head and wetted parts.
The system must be designed to allow full, unobstructed access to the vessel, head and their interior surfaces for cleaning, inspection and maintenance.
After the assembly process is completed, the autoclave system shall be shop tested to insure proper operation before shipment.
General Practices All electrical equipment, wiring, conduit, panels, motors, etc. shall comply at the time of the bid with the current editions of the National Electric Code (NEC) and the Occupational Safety and Health Act (OSHA).
All electrical components shall bear either the UL label, the label of a nationally recognized laboratory, or the label of the local governing authority where required. Bidder shall list any item or area where compliance is not possible.
Properly sized circuit breakers, fuses and thermal overloads shall be furnished with all starters, disconnects, and control circuits as required Delivery Date: Above-mentioned
