Chapter microsoft visio 2010raw.com free is concluded by selection of a suitable overall process for design and is justified based on the relative merits and demerits of available processes identified during the literature survey.

An appraisal of the process is carried продолжить under Chapter 02 by analyzing its economic, safety and environmental aspects. The economic feasibility of the production plant 2010eaw.com been evaluated in terms of estimated capital and running costs, and revenue projections based on forecasts. Possible physical, chemical and electrical hazards associated with the production process have been addressed under Chapter 02 as well, and safety standards to be used in design and construction have been pointed out.

The environmental impact of species involved in the production process is analyzed in chapter 02, along with references on 201r0aw.com limits. Detailed calculations of mass and energy balances conducted for the potential process streams of the plant using MS Excel are included in Chapter Mass flow rates frse the mass balance were calculated on a component by component basis, based microsoft visio 2010raw.com free process requirements.

The mass flow rates along with literature referred or assumed stream temperatures were used for the energy balance. Since equipment specific energy inputs such as energy transfer by work done imparted by pumps, compressors, agitators etc could not be determined 2010raw.com this stage of the design, which for the most part is an overall analysis, a percentage provision of the total energy transfer by mass transfer were allocated.

Utility requirements were evaluated based on the energy deficits or surpluses made apparent in the energy balance. Microsoft visio 2010raw.com free final chapter of the report contains the Process Flow Diagram PFD of the microsoft visio 2010raw.com free as well as mass and energy flow sheets as concluding submissions along with recommendations and key observations made in the design.

The report that follows contain a detailed methodology of the approach adopted in this нажмите для продолжения which includes a comprehensive survey of available literature and an overall selection of a manufacturing process; the feasibility of the design in terms of safety, environmental and economic aspects; a detailed balance of bisio and energy of process and utility microsoft visio 2010raw.com free required, and a set of diagrams depicting the process flow and flow sheets of mass and energy.

The initial review of literature revealed that the current production capacity of Sulfuric acid was around million tonnes per year, and is currently growing at about 1. A majority of its production is driven towards fertilizer and related products. The production was scaled up microsoft visio 2010raw.com free correspond to 35 MTPD of Sulfur input, to account for future growth in demand for oil refining in Sri Lank and the resultant petrochemicalsas well as increased local demand for Sulfuric acid itself which is likely to occur following the production of sulfuric acid locally.

It was calculated that the plant could be constructed microsoft visio 2010raw.com free a cost of USD 7. Microsoft visio 2010raw.com free group recommends that by the plant could be run at full capacity at which point, with the forecast rise in price per kg of Sulfuric acid, sales would produce up to USD In this set up the plant is expected to start accumulating profits in the first quarter ofdelivering a pay back of 7 years and 1 month.

In terms of economic feasibility, the project could be concluded as being viable; however, the group recommends that a more exhaustive calculation procedure be used to estimate 200raw.com flows if closer inspection is microsoft visio 2010raw.com free with reduced assumptions.

The group in its analysis for a suitable site has selected the general area of Sapugaskanda as a suitable location for installation of the plant, taking into account its close proximity to the CPC as well as the Colombo harbor as well as established infrastructure and availability of water and other microsoft visio 2010raw.com free.

Among the findings microsoft visio 2010raw.com free by the group during the mass and microosft balance was the fact that Oleum could be microsoft visio 2010raw.com free as a drying agent a form of chemical drying to dry air and Sulfur Dioxide streams instead of jacketing with steam.

The group was able to 201r0aw.com from the mass читать далее energy ffree that the cooling utility would amount to 2.

It is recommended that a detailed pinch analysis be conducted to determine this figure more accurately. Though energy could be recovered as saturated steam, the group has identified that due to the magnitude of the temperatures required for process heating, the saturated steam recovered would have to be superheated first. Alternatively it is recommended by the group is that thermic fluids be used in this regard, while the excess microsoft visio 2010raw.com free capacity could be utilized for in house generation of power.

The group recommends the conduction of a proper cost benefit analysis comparing the capital costs of installing a power plant and using thermic fluid for process heating, as opposed to those associated with using superheated steam entirely for process heating. As a concluding remark a reflection on the personal benefits and underlying reasons for performance could be made.

The group notes the personal benefits of obtaining valuable insights in to the financial side of process engineering as well as a holistic sense of plant design in terms of conducting mass and energy balances and investigating safety and environmental issues. The group observes that continuous feed back and coordination being the underlying current of successful performance of a project of this magnitude.

Material safety data sheet of sublime Sulfur Material safety 2010rawcom sheet of Sulfuric acid Direct contact of Sulfuric acid with anything from tissues e. Concentrated forms of the acid have strong dehydrating and oxidizing properties. According to the Encyclopedia Britannica, upon heating, partial decomposition of microsoft visio 2010raw.com free pure acid into water and SulfurTrioxide occurs, with SulfurTrioxide escaping as vapour, until the concentration of the acid fall to Its applications has a wide range- from the manufacture of fertilizers, pigments, dyes, drugs, explosives, detergents, and inorganic salts and acids, to petroleum refining and metallurgical processes, electrolyte in lead—acid storage batteries etc.

Beginning of Industrial scale production: In the s Sulfuric acid had been manufactured mainly for the Leblanc process for making Sodium Carbonate. Johann Glauber had pioneered the process of by burning Sulfur with saltpeter potassium nitrate microsofh the 17th century History of Sulfuric Acid, Where previous production had mainly been lab scale based, it was during this time that the economic value of Sulfuric acid has started being realized among industry visionaries.

But the best days of Sulfuric acid had still not come microsoft visio 2010raw.com free pass. Breakthrough: The development of the Lead Chamber Process by John Roebuck in the mid 18thcentury was a milestone in Sulfuric acid production, as it afforded the industry to increase production capacity; even more significant about this was that the process was deemed far more economically viable than any other processes hitherto developed for Sulfuric acid.

The 2010rw.com decades saw 2010ras.com improvements to the said process — where increased recovery of Nitrogen Oxide was achieved, thereby contributing towards the overall improvement of the Lead Chamber Process. Pinnacle: The evolution of Sulfuric frfe production microsoft visio 2010raw.com free its climax in the beginning of the 19th century, where Phillips, in Bristol, England, patented the oxidation of SulfurDioxideinto SulfurTrioxide over a Platinum catalyst at high temperature.

The popularity of the microsoft visio 2010raw.com free process also improved the lead chamber process, due to competitive advances of the production industry. The increased demand for more concentrated forms of the acid which was far easier and more possible with the Contact Process than the Lead Chamber Processcoupled with lower costs of production associated with using cheaper catalysts and the resulting lower price led to 2 This section contains information of alternative processes that are elaborated in detail in mmicrosoft sections.

Though the basic principle viio the contact process remains unchanged to this day, with the dawn of the 20th century, the contact process underwent the following improvements Lloyd, Vanadium Pentoxide. V2O5 also had the added advantage of being more robust to catalyst poisoning and subsequent deactivation. Further the air microsoft visio 2010raw.com free for oxidizing Sulfur Dioxide need not be dry. With this the capital and operation cost for the plant was reduced due to reduction of drying machinery equipment, heat recovery systems, reduction in cooling water and by-product production.

This phenomenon involves adding the elementary Sulfur Trioxide absorption step ahead the final catalytic stage. The introduction of environmental regulations during the period fuelled this development. Iron and steel manufacturing: Sulfuric acid is used to remove rust, scaling and other forms of oxidation from rolled sheet and billets before being used for the manufacture of automobiles увидеть больше other appliances.

SAR units have been incorporated in metal smelting plants, oil refineries, and other industries that require bulk quantities of Sulfuric acid. Also Aluminium Hydroxide which is used as a coagulant in water treatment plants is also manufactured from Sulfuric acid.

Manufacture of Ammonium Sulfate: An important nitrogen fertilizer, this is produced in mass scale by reacting Ammonia with Sulfuric acid where Ammonia is converted into Ammonium Sulfate which gets crystallized and is separated by centrifugation or filtering Gowariker, Ammonia being a byproduct in coking plants is often supplied to iron and steel making plants along with coke to produce the above as a byproduct, which is used as a form of disposal of waste Sulfuric acid.

The byproduct is then sold as an microsoft visio 2010raw.com free chemical. Application as a catalyst: Table 1. Sulfuric acid is also used as the electrolyte in lead-acid car batteries.
