CHAPTER-3 METHODOLOGY 3.1 Location: An audit has been made on VCRS at Dr. Reddy pharmaceutical Private LTD Hyderabad (A.P.). In this plant the compressor in vapour compression refrigeration system compresses the refrigerant. A semi-hermetic screw compressor is provided to ensure high operational efficiency and reliable performance. Capacity control is achieved through slide valve. The compressor is a positive displacement type characterized by two helically grooved rotors, which are manufactured
Description of the section The refrigeration process of mixed refrigerant cycle consists of three compression units and heat exchangers which are connected in the sequences of main cycle. In this part, the second compression process of the mixed refrigerant (MR) will be described in the primary cryogenic process. The stream that leaves the first heat exchange unit enters the second compressor. The large amount of energy is used in the compression process due to the high rotation and fluid movement
can be arranged, following schemes, which makes easier the prediction of the flow, issuing from a jet system with endless number of openings. In the case of “in-corridor” ordered nozzles, the jet system with endless number of opening is described by 9 jets (3x3), as shown in Fig. 1. Every 8 jets, that surround а central jet, are representative for the whole system and play the role of
activated or deactivated at a certain time. With this type of crystallizer, the flow direction of citric acid is always from top to bottom. As it enters the unit, the citric acid is uniformly distributed across the entire crystallizer cross section by a slowly rotation of hydrofoil impeller. The cooling water can be re-cooled in a separate cooling unit or in an air
vAs discussed above, India is a major producer of food (fruits, vegetables, wheat, pulse, milk, spices etc) in the world. India is addressed as the ‘Food Bowl’ of the world which may not be a fallacy (Figure 1.1). The production of food in India has shown a steady growth in the recent past and according to the Ministry of Agriculture of India, the trend will continue in the coming decade. The growth for food sector in India can be attributed to diverse habitats it offers. The country has rich spectrum
Chapter – 1 INTRODUCTION 1.1 Chapter Summary This chapter starts with the scope of improvement in sugar manufacturing process. Section 1.2 presents the objective of proposed research work. The historical background of sugar and statistics of Indian sugar industry is explained in section 1.3 and the chemical composition of sugar cane is described in section 1.4. The overview of sugar making process is explained in section 1.5. In section 1.6 of this chapter important terms used in cane juice extraction
in some form since people first began to write software. In its simplest form, two programmers sit down in front of one computer terminal and trade off use of the keyboard and mouse, talking out loud as they work through the software coding process.[9] This is a great way to train new programmers. But research also shows pair programming, when the coders work well together, increases productivity and code quality. This seems rather obvious on its face: two heads are better than one, whether it is
FLEXURAL BEHAVIOUR OF POTASSIUM BASED GEOPOLYMER CONCRETE. D.Vasuki1, A.Kalaivani2 1PG Student, Department of Civil Engineering – Paavai Engineering College. 2Assistant. Professor, Department of Civil Engineering – Paavai Engineering College. ABSTRACT The global usage of cement occupies the second position next to water. As the development of country and infrastructure, their materials needed get increased. Meanwhile for the development of the infrastructure concrete plays the
CHAPTER: 1 EXECUTIVE SUMMARY Petroleum is one of the primary sources of energy. It is the back bone of industries. It goes through a long chain from exploration to retailing- before it is available for usage in different forms. In our country, the Refining business is primarily dominated by Public Sector Undertaking Companies like Indian Oil Corporation Ltd. (IOCL), Bharat Petroleum Corporation Ltd. (BPCL), Hindustan Petroleum Corporation Ltd. (HPCL), etc. Apart from PSUs, major player in this sector
