Thermal Process Hazards
Product Description : • A major hazard in chemical production and storage of chemicals is loss of thermal control, which can lead to destruction and release of toxic substances. A systematic risk analysis is essential in order to define the critical limits of temperature, dosing, storage temperature etc. A systematic risk assessment must include the following stages.
1. Compilation of basic data (physical and chemical properties, reactivity data, interactions between chemicals, equipment data etc.)
2. Define system (boundaries of safe process conditions)
3. Identify hazards (e.G. Check lists, hazard and operability studies (hazop))
4. Assess risks (estimate severity and likelihood)
5. Select risk reduction measures (e.G. Technical, organizational, personnel)
6. Remaining risks
thermal process safety data of chemical reactions requires knowledge of the thermodynamics and kinetic properties of both wanted and unwanted reactions. Thermal process safety for physical operations (e.G. Discharge, distillation) normally requires the thermodynamics and kinetic properties of unwanted reactions.
chilworth technology has a fully equipped laboratory to determine the thermal data necessary for thermal process safety and storage of chemicals, evolved gas collection and analysis, physical properties testing and transportation requirements testing under the united nations guidelines. The professionals at chilworth have many years of industrial experience and expertise in thermal process safety and can provide total solutions to process and operational hazard analysis from compilation of basic data to solving thermal process safety requirements.

Vent Sizing / Relief System
Product Description : • Vent sizing and emergency relief system studies are undertaken to verify the proper equipment and/or safety precautions utilized during the processing steps. To achieve this objective, the `study-scope` specification usually covers the aspects of vapour relief calculations, reaction hazard assessment and may include or exclude decomposition reactions depending on the requirement. The study consists of a number of discrete tasks shown below. The fire engulfment calculations form the most straight-forward aspect of the study. The chemical reaction hazards study is a considerably more detailed task and is usually broken down into a larger number of discrete tasks. This study requires basic data information on the processes also. Some indication of the tasks undertaken as part of the study are shown below
task 1: vent sizing for fire engulfment emergency relief vent sizing procedure
task 2: risk ranking of chemical reactions
task 3 : experimental characterisation of chemical reactions
task 4 : identification and selection of process deviation scenarios
task 5 : experimental characterisation of runaway reactions
task 6 : vent sizing for runaway reaction
