Crude oil and natural gas are naturally occurring hydrocarbons found in many areas of the world in varying quantities and compositions. In refineries, they are transformed into different products as: In order to manufacture these products, these raw materials are processed in a number of different refining facilities.

The combination of these processing units to convert crude oil and natural gas into products, including its supporting units and facilities, is called a refinery. The market demand for the type of products, the available crude quality and certain requirements set by authorities influence the size, configuration and complexity of a refinery. As these factors vary from location to location no two refineries are identical.

Refineries discharge waste water which originates from: These waters have been in contact with the process fluids, and apart from oil, will also have taken up hydrogen sulphide H2S , ammonia NH3 and phenols. The more severe the conversion processes, the more H2S and NH3 are taken up by the process water. The process water is treated in several, well-known steps before discharge to the environment.

General overview of the refinery processes Crude oil and natural gas are mixtures of many different hydrocarbons and small amounts of impurities. The composition of those raw materials can vary significantly depending on its source. Petroleum refineries are complex plants, where the combination and sequence of processes is usually very specific to the characteristics of the raw materials crude oil and the products to be produced. In a refinery, portions of the outputs from some processes are fed back into the same process, fed to new processes, fed back to a previous process or blended with other outputs to form finished products.

One example of that can be seen in Figure 2. The production of a large number of fuels is by far the most important function of refineries and will generally determine the overall configuration and operation. Nevertheless some refineries can produce valuable non-fuel products such as feedstocks for the chemical and petrochemical industries.

Nelle raffinerie, essi sono trasformati in diversi prodotti, quali: Ai fini della fabbricazione di tali prodotti, queste materie prime sono lavorate in un determinato numero di varie strutture di raffinazione. Le raffinerie scaricano acqua reflue derivanti da: Tali tipi di acqua sono state a contatto con liquidi di lavorazione e, a parte il petrolio, hanno anche assorbito solfuro di idrogeno H2S , ammoniaca NH3 e fenoli. In una raffineria, parti delle produzioni provenienti da alcuni processi sono alimentate nuovamente nello stesso processo, alimentate su nuovi processi, alimentate nuovamente a un processo precedente o miscelate con altre produzioni per formare prodotti finiti.

Ciononostante, alcune raffinerie possono produrre prodotti non combustibili preziosi, come i feedstock per le industrie chimiche e petrolchimiche. Freeze Dryer Use Manual General field: Instruments Source text - English 3. Operating Hazards The following points should be observed when operating the freeze dryer. Operators should read all instructions pertinent to the operation of the freeze dryer before starting any work on the unit.

Ensure all materials especially organic solvents are removed from the system before start up. Ensure all necessary pre-start and maintenance checks are performed before start up. When taking instrument readings, verify the gauges indicate true results and the values are not influenced by other factors as explained in the Operating manual.

Do not tamper with pressure switch or pressure relief valve settings or any hydraulic safety device. The accumulation or use of dangerous cleaning materials will damage the plant vacuum pump oil contamination and process, and possibly created a hazardous condition. The freeze dryer is NOT flameproof and not intended for the processing of volatile or flammable materials.

If there are any problems with the unit contact a service technician before attempting service.

Do not de-activate or override any safety devices. Wear proper PPE to load or unload the products in the chamber. If this machine is equipped for steam service, alarm line should be used around the machine during SIP cycle. Pay attention to the hot surface after SIP around the sterile filter, the pipes, the valve bodies and the vessel glasses. The alarm line can be taken away 1h after the completion of SIP 4. Mechanical Warnings Lifting - Operators should be trained in the techniques of lifting, handling the equipment and in the use of any lifting or handling devices.

This unit is NOT Explosion proof. Guards - Some refrigeration components are not insulated, because of need to service the component. These components can be hot or cold. Protect against skin contact near these pipes and components by the use of appropriate personnel protection equipment. Prevent accidental contact during loading and unloading of the chamber.

Note, loading cold shelves can be particularly hazardous, always wear appropriate gloves during this procedure. Note, only experienced refrigeration service technicians should work on refrigeration systems. Fire Warnings Silicone oil- there is a risk of silicone oil fire if the temperature switches do not work well.

If it happens, large fire: Extinguish with foam, water spray. Carbon dioxide CO2 , water spray. Do not use flammable materials in or around the freeze dryer. Some special designed equipment can be used to treat flammable solvent product. But still, the equipment is not explosion proof. If it happens, use different fire fighting solutions for different chemical solvent. Electrical Equipment Fire —there is a risk of fire that may be caused by some electrical equipment. Disconnect the power supply switch before servicing equipment.

Have only qualified Electricians connect the freeze dryer to electrical power sources. Chemical Warnings Toxic Products - Do not allow the vacuum pumps to emit oil mist, solvents or other toxic substances from the process, into the working atmosphere. Exhaust must be vented to a safe area and suitably treated to comply with local legislation.

Refrigerant gases - though low in toxicity can pose asphyxiation hazards and hazards to the environment. Do not expel refrigerant to the atmosphere during servicing of the system. Aggressive Fluids - Do not use cleaning fluids and process materials containing Chloride ions.

Safety and Handling Considerations General field: Such information should be requested from the supplier s of any product s prior to working with it them. The comments that follow are pertinent only to the resins discussed, as supplied. Various additives and processing aids used in fabrication will have their own safe use profile and must be investigated separately.

      Health and Safety Polyethylene resins are among the most inert commercial polymers and constitute no hazard in normal handling. Normal good housekeeping practice should be followed. Workers should be protected from possibility of skin or eye contact with molten polymer. Safety glasses are suggested as a minimal precaution to prevent possible mechanical or thermal injury to the eyes.

      Fabrication areas should be ventilated to carry away fumes or vapours; workers should be assured of supply of fresh air. Workplace environments should be kept clean and free of dust.
