| Abstract: Agriculture is the backbone of Indian economy. Up to 70% of the population is engaged in farm sector directly or indirectly. Growing Indian population needs sufficient farm product. Farming and the agriculture crops are susceptible attacks by various kinds of pests in form of insects, fungus, bacteria or virus or weeds and control of these has become necessary to reduce losses to a minimum. With the green revolution spreading in rural areas, the demand for both fertilizer and pesticides is on the increase.
According to current trends in world population growth and industrialization, waste and pollutants are released faster than the earth can absorb them. Natural resources are consumed faster than they can be restored. According to some assessments, reductions of over 90% on material throughput, energy use and environmental degradation will be required by the year 2040 to meet the needs of a growing population within the planet’s carrying capacity.
In the last half of the 20th century there has been a growing worldwide movement among government and industry to change the way industry interact with the environment. Cleaner production is outcome this progress. Cleaner production is a way of looking at what causes waste and then figuring out the best way to reduce the pollution before it is created.
Historically, people looked for ways to control pollution after it was created while here emphasis on “source reduction”. Try to reduce the waste first and then recycle. This approach can benefit the environment and save money. This is what industries are looking for profit. Cleaner production is best technique for environmental protection with economical benefit. |

| Abstract: In the present reduction process with iron powder and hydrochloric acid produce dasda plus ferrous chloride. The ferrous chloride is the by product of the DASDA process.
During the reduction process it produces the large quantity of solid ferrous chloride.
• The practically iron-free quality required for use as a starting product for optical brighteners can only be achieved with difficulty after the process of reduction with iron.
• In this process, after the reduction, a considerable technical effort is required in order to separate the reducing agent from the 4,4'-diaminostilbene-2,2'-disulphonic acid – hereafter referred to as diamino-acid -- the iron arising as an iron hydroxide sludge which is difficult to filter and which, in order that it can be dumped or utilised technically, must be worked up by drying or roasting
• It is a hazardous solid waste
• It reduce the efficiency of the rector
• Due to large quantity of by product it takes difficulty to dry.
• It operates high temperature.
• It reduces the quality of the product.
• It increases the reaction time.
• Due to increase in time period of reaction reduce the productivity of the company.
The subject of the invention is a technically simple processfor the preparation of 4,4'-diaminostilbene-2,2'-disulphonic acid by catalytic reduction of 4,4'-dinitrostilbene-2,2'-disulphonic acid in the form of the water-soluble alkali metal salts. 4, 4’-Diaminostilbene-2, 2’-disulphonic acid is an important intermediate product for the preparation of optical brighteners. The reduction of 4, 4’-dinitrostilbene-2,2'-disulphonic acid – here after referred to as dinitro-acid -- has hither to been carried out with iron in acid solution.
In this process, after the reduction, a considerable technical effort is required in order to separate the reducing agent from the 4, 4’-diaminostilbene-2,2'-disulphonic acid – hereafter referred to as diamino-acid -- the iron arising as an iron hydroxide sludge which is difficult to filter and which, in order that it can be dumped or utilised technically, must be worked up by drying or roasting. The practically iron-free quality required for use as a starting product for optical brighteners can only be achieved with difficulty after the process of reduction with iron.
It has been found that diamino-acid can be prepared by catalytic hydrogenation of dinitro-acid. The process according to the invention is characterised in that an alkali metal salt of dinitro-acid is hydrogenated on a cobalt catalyst, or catalyst containing cobalt, in particular on Raney cobalt, in the temperature range of 70.degree. To 180. Degree. C under a hydrogen pressure of 5 to 150 bars in an aqueous medium in the pH range of 6.0 to 8.5. This process gives a diamino-acid in more than 95% yield and in high purity. This is all the more surprising since hitherto no generally industrially applicable process for the selective catalytic reduction of nitro groups next to double bonds was available.
The literature contains contradictory statements on the hydrogenation of 3-nitrostilbene
(M. Freifelder: Practical Catalytic Hydrogenation, N.Y. 1971, page 193). Using nickel, 1,4-bis-(3-nitrostyryl)-benzene is attacked both at the nitro groupsand at the double bonds.
Again, when using platinum catalysts, selective hydrogenation of the nitro group next to the olefinic double bond is only possible in special cases (Rylander: Catalytic Hydrogenation over platinum Metals, N.Y. 1967, page 178 and F. Zymalkowski:Katalytische Hydrierungen im
Organischchemischen Laboratorium (Catalytic Hydrogenations in Organic Chemistry Laboratories),
Enke-Verlag, 1965). The catalytic reduction of p-nitrophenyl acrylate on various catalysts gives p-nitrophenyl propionate. Dinitro-acid is reduced on nickel catalysts to diamino-acid with large proportions of
4, 4’-diaminodibenzyl-2, 2’-disulphonic acid.
The cobalt catalyst employed according to the invention can be employed in the reduced form or be obtained by reduction from cobalt compounds under the conditions of the process. It can be advantageous to add to the catalyst promoters such as metals. |

| Abstract: This project report includes detail study of the process plant manufacturing of perfumes intermediates such as phenyl ethyl alcohol, phenyl ethyl methyl ether, styrene oxide, and sterile acetate. Also includes material balance, energy balance, & equipment design, etc. with special emphasis on vacuum distillation in process plant. There are many types of distillation are used for the purification of compounds having different properties. But, for these type of thermally sensitive materials, vacuum distillation is mostly favorable. Vacuum distillation works on the principle that boiling occurs when the vapour pressure of a liquid exceeds the ambient pressure. Utilizing vacuum distillation can reduce the height & diameter and thus the capital cost of a column. But the main engineering problem in utilizing vacuum distillation is to control the vacuum pressure into column. Vacuum pressure in column can be measured by using pressure relieving devices such as Capsule Gauge, McLeod Gauge, Bell type pressure Gauge, etc. & many electronic devices are also available which measures from 10 mbar down to 10-11 mbar vacuum. By using such type of devices and other methods we can control vacuum in column and thus reduces the energy required for separation. |

| Abstract: Due to the pressure for profitability, but also due to the need to address environmental issues inherent to cement production, the number of cement plants using alternative fuels has increased dramatically over the last few years. Management goals are to reduce thermal energy costs, but also to be more environmentally friendly by substituting traditional fossil fuels. Alternative fuels, albeit interesting in economical and environmental sense, are difficult to dose, have high calorific value variability, and thus impose the need for automatic control to ensure good process conditions in the kiln.
The controllers presented in this work were implemented on Expert Optimizer, a commercial advanced process control and optimization platform. The underlying controller technology is Model Predictive Control, which is implemented in a graphical modeling environment. The graphical interface allows the model to be constructed from easily understandable and configurable sub-models. The modeling environment is such that the optimization problem is constructed by dragging generic modeling elements from the library, and dropping them on the model space. The model predictive control problems are then generated from this graphical representation. The goal is that the complexity of the mathematical formulation can be hidden from the users, increasing the ease of use and decreasing the cost of ownership.
Energy costs and environmental standards encouraged cement manufacturers world-wide to evaluate to what extent conventional fuels can be replaced by alternative fuels, i.e. processed waste materials. Clinker burning is well suited for various alternative fuels. In order select a suitable alternative fuel a commercial modelling tool is used to model the four stage pre-heater kiln system of a full-scale cement plant (clinker production ~ 2900 tons/day), using petcoke as fuel. The goal is to optimise process control and alternative fuel consumption while maintaining clinker product quality. |

| Abstract: In PTA-1 Plant, during manufacturing of PTA, there is necessary to give a caustic wash of rotary vacuum after each 3 days in filtration process in oxidation section. It is caused due to cloth blinding after certain time of continuous operation of rotary vacuum filter. So this operation of caustic wash is carried out to clear the filter cloth of RVF. But while giving caustic wash, at that time filtration is not running on and hence it affects on production. On other side production cost of caustic soda (NaOH) is high and hence it affects on production cost. Therefore it is required to reduce the caustic wash frequency of rotary vacuum filter. Caustic wash frequency can be reduced by solvent wash and also by improving quality performance that is done by decreasing the level of impurities such as high color or 4CBA. As a solution of this problem, I had chosen that Caustic wash frequency can be reduced by solvent wash which is better solution than any other and I had worked on that in detail. |

| Abstract: The goal of carbon sequestration is to capture CO2 that would otherwise accumulate in the atmosphere and put it in safe and permanent underground storage before they contribute to climate change.
Most proposed methods would capture CO2 from concentrated sources like power plants. Indeed, on-site capture is the most sensible approach for large sources and initially offers the most cost-effective avenue to sequestration. The challenge is to separate CO2 at a low cost and continuously isolate it safely and securely over the long term. CCS technology is garnering attention as a bridging technology in the new energy society of the next generation. Carbon capture and storage (CCS) involves the responsible utilization of fossil fuels without endangering the planet.
CO2 absorption technology is well understood and widely used. Experimental work and simulation using ASPEN PLUS has been carried on various aspects of the absorption process. In such experiments the system pressure and temperature is set. The CO2 partial pressure and CO2 concentration in the liquid is then determined. Results from such experiments are used to generate plot to study the effect of various parameters like amine concentration, gas flow rates on CO2 absorption process. |
