Safety and Risk Engineering Facility

Mission: To develop and dissipate knowledge of safer and cleaner process operation

Description

Process safety and risk management focuses on activities or events involving accidental release of chemicals and industrial wastes, and deals with the prevention of catastrophic and dangerous occurrences that have a negative impact on human safety, health, environment and the overall viability of an enterprise. It includes activities such as accident forecasting, impact assessment, quantification of risk to industry, human health, environment and business, and development of strategies for prevention and control of such occurrences. All these activities require precise information about chemicals, their behavior under different operating conditions, process upsets, and design parameters. Many of this information may be derived through experimentation. This lab provides basic infrastructure facilities for investigating chemical behavior in different operating conditions (especially in offshore operating conditions), process upsets leading to accidents, and setting up of design parameters for safety measures.

Objectives

The basic objective of this facility is to predict behavior of the process in order to:

  • judge the suitability of the proposed process or operation
  • produce data for engineering purposes including regular operation as well as operation under upset situation
  • investigate measures to prevent the upsetting situation that may lead to accidents.
  • design process safety measures to deal with eventualities.
  • test designed safety measures against unexpected side reactions, decomposition, or chemicals and mixtures.
This lab also aims to develop new models and methodologies for:
  • accident forecasting
  • probabilistic risk assessment
  • risk based safety measure design
  • risk based inspection and maintenance management
In process facilities (offshore or onshore) there may be many types of hazards present, however this facility focuses on three main types of hazards:
  • pressure hazards
  • thermal hazards
  • reactive hazards

Thermal Fluids Laboratory

The thermal and fluids laboratories within the mechanical engineering department contain a number of facilities for conducting experimental studies in fluid dynamics and heat transfer. In addition to those listed below, the ocean and naval engineering department also maintains a 58 m tow tank with wave generation capabilities and a deep water test tank. The civil department also maintains a water flume of approximately 2' cross-section. Facilities for conducting research in electronics cooling, process flow and heat transfer, and heat exchanger modeling include:

  • 36" Low Speed Wind Tunnel: Open circuit wind tunnel with a 3' x 3' test section. Airflow is controlled using a vane damper at the fan inlet. Air speed can be varied from 0-15 m/s (0 – 30000 CFM). Data acquisition is fully automated using a PC/Data logging system using Labview.
  • 12" Low Speed Variable Orientation Wind Tunnel: This unique, multi-purpose wind tunnel is designed for mixed and forced convection testing for horizontal, vertical and inclined geometries. By rotating the test section and duct assembly about a pivot axis coincident with the centre line of the blower, the test section can be set to any angle between vertical and horizontal. The contraction section in the inlet plenum has a 9:1 contraction ratio and a 10 cm (4 in.) thick honeycomb flow straightener that reduces non-uniformities in the mean flow field and produces a relatively uniform velocity profile at the entrance of the test section. The removable, 30 cm x 30 cm x 60 cm (12" x 12" x 24") test section is generally large enough to accomodate most common test specimens. Airflow velocities of 0 - 15 m/s (0 - 3000 CFM) are controlled using a TB Woods frequency-based speed regulator.
  • 6” Low Speed Multi-Purpose Wind Tunnel and Impingement Flow Facility: These two wind tunnels were designed for examining thermal performance of heat sinks and other air cooled assemblies such as automotive radiators. The flexible modular design allows for custom test sections to accommodate a number of applications including impingement flow in electronics cooling and air cooled automotive radiators. The tunnel is equipped with a 500 CFM variable speed fan. Maximum air velocity at open section is approximately 10 m/s. A companion facility allows for vertical jet impingement cooling studies to be performed.
  • 3” Multi-Phase/Two Phase Flow Loop: A 3" diameter two phase flow loop has been constructed at Memorial to investigate oil-water-gas flows. The facility was initially designed to support the development of an electro-quasi-static multi-phase flow meter (MPFM) to measure the individual oil-water-gas flow rates of unprocessed oil well streams. The flow loop is a 65 m re-circulating open circuit system, and is constructed of 3-inch diameter pipe. There are clear horizontal and vertical test sections for flow visualization and measurements. Instrumentation includes several pressure and temperature transducers, and flow meters on the gas and liquid lines to measure the individual gas and liquid flow rates. Electro-pneumatic control valves are installed on the liquid and air lines to facilitate control of the flow conditions, and a wide range of flow regimes can be generated. Operational control of the loop is implemented through a fully integrated computer system which is also used for data acquisition and high speed imaging. Quantitative flow visualization techniques, in combination with hot-film anemometry measurements have been used to study and characterize the different flow regimes. The system is also equipped with a laser based Particle Image Velocimetry (PIV) system to aid in velocity and flow composition analysis and a variable speed pump controller.
  • Mini Single and Two Phase Flow Loop: This new flow loop was designed to study single and two phase flow characteristics in minichannels and compact heat exchanger cores. It allows both the thermal and hydraulic characteristics of compact heat exchanger cores and liquid cooled electronics assemblies to be determined. Typical flow range would allow liquid flows to vary from 0.05 – 60 Lpm of liquid flow using a variable speed pump, 0 – 50 Lpm of air flow provided by a compressor, pressure measurement in the range of 0 - 60 psig, and fluid operating temperatures up to 120 C. Various test fluids will be used such as glycerin, glycol, automotive oils, water, and water/glycol mixtures. The facility also allows for liquid to liquid, liquid to air cooling, and liquid cooling only, studies to be conducted. Thermal input is provided through a constant temperature fluid reservoir or by means of electric heaters using a 1200 W power supply. Data acquisition is fully automated using Labview.
