Paper , Order, or Assignment Requirements

1. You will need to understand and explain the basic process for a sugar cane molasses distillery producing 95% ethanol as its main product. Identify the key components of safety and environmental legislation and regulations under which the facility will likely be captured. Develop preliminary process information to inform the safety and environmental hazard assessment. This may include:
a. A brief process description;
b. Description of key unit operations;
c. Process & instrumentation diagram;
2. Description of process materials including raw materials, process additives, products and waste streams. For the production rate given above and investigated ratios of chemical production, estimate the production rates of chemical flows (in kg/s). You do not need to calculate heating flow requirements. Undertake an initial safety hazard assessment of the proposed facility including:
a. Identification of key hazards;
b. Assessment of raw material, chemical storage requirements and product
transportation issues.
Please reference your source(s) of process information.
3. Once you have the above information, carry out a HAZOP of the equipment and process shown in the attached process flow diagram. Make the required additions to the diagram.
4. Describe the steps required leading up to an Environmental Impact Statement (EIS) as described in the Queensland Government website and as noted in your lecture notes. Carry out an EIS. Include
a. Assessment of potential impacts of the facility on water, land and air systems;
b.
Assessment of process waste streams; You will need to include the consideration of options for the disposal and/or reuse of the byproduct ‘vinasse’ after the mash is fully processed, as well as the product chemicals noted in the attached process flow diagram and
c. Mitigation options for the issues that have been identified including consideration of process alternatives.
