Classification studies of lead–zinc ore fines using Water-Injection cyclone
International Journal of Mineral Processing, 2005Co-Authors: K. Udaya Bhaskar, B. Govindarajan, J. P. Barnwal, K. K. Rao, B. K. Gupta, T. C. RaoAbstract:Classification studies to recover liberated particles of lead and zinc minerals from a ground lead–zinc ore were carried out using a 100-mm Water-Injection cyclone. The effects of variables on the performance of Water-Injection cyclone are discussed. The results indicated that the Injection Water rate has a complex interaction with the other variables like spigot opening, feed inlet pressure, and vortex finder opening. A set of empirical equations for slurry throughput, corrected cyclone cut size, minimum distribution point, and reduced efficiency numbers was developed for predicting the performance of Water-Injection cyclone. Finally, the results obtained in Water-Injection cyclone are compared with the data obtained on a similar diameter (100 mm) hydrocyclone.

Modelling Studies on a 100 mm Water-Injection Cyclone
Physical Separation in Science and Engineering, 2004Co-Authors: K. Udaya Bhaskar, B. Govindarajan, J. P. Barnwal, K. K. Rao, T. C. RaoAbstract:Test work on a 100 mm Water-Injection cyclone was carried out using a ground lead-zinc ore. Experiments were conducted varying the vortex finder diameter, spigot diameter, feed inlet pressure and Injection Water rate. The effect of variables on the performance of the Water-Injection cyclone in terms of slurry throughput and corrected cut-size are presented. A set of equations have been developed for predicting the performance of a Water-Injection cyclone. Further, the reduced efficiency curve was quantified to predict the size distribution of Water-Injection cyclone products.

Performance evaluation of Water-Injection cyclone treating a synthetic mixture
2000Co-Authors: Udaya Bhaskar, B. Govindarajan, J. P. Barnwal, T. C. RaoAbstract:The effect of change in operating variables i.e., vortex finder diameter, spigot diameter and Water Injection rate on different performance numbers is studied in Water-Injection cyclone treating a synthetic mixture of atomized Ferro-silicon and ground silica sand. Suitable empirical models relating the operating variables and fines (below 25 microns) recovery, ferr-o-silicon and silica recoveries in the overflow product and the separation efficiency at 25 microns size are developed. At comparable levels of operating throughput, the performance numbers obtained in a 100mm Water-Injection cyclone and a 100mm normal hydrocyclone are discussed. An overall fines recovery of 85.6% was obtained in the overflow product of Water-Injection cyclone whereas in a normal hydrocyclone the combined fines recovery in the overflow product was 46.2%. Similarly the ferro-silicon recovery at fines below 25 microns in the overflow product from Water-Injection cyclone was 55.5% while that of hydrocyclone was only 9.8%. Also, silica recovery at fines below 25 microns in the overflow product of a Water-Injection cyclone was 98.6% in comparison to 82.1% in a normal hydrocyclone. Separation efficiency values obtained between coarse and fine products at 25 microns in the overflow product of Water-Injection cyclone and hydrocyclone were 83.5% and 45.8% respectively which indicates sharper classification in Water-Injection cyclone.

Layout Optimization of the Star Oilfield Water Injection Network
Energy Conservation Technology, 2013Co-Authors: Wang Mei-weiAbstract:Oilfield Water Injection network system plays an important role in the normal development and production of the oil.Massive investment,planning and design of Water Injection network oil directly affects the investment of Water Injection network oil construction.In order to seek the optimal design method for oilfield Water Injection network effectively,with oil satellite Water network system as the research object,the shortest total length of the pipeline as optimization objective,the uniqueness of the relationship between the wells and stations,the numbers of Injection wells connecting to station and other restrictions as constraint conditions,we establish the mathematical model of oilfield Injection network layout optimization based on electromagnetism-like mechanism algorithm,and numerical example is also given.The results show that it is feasible for the oilfield star Injection network layout optimization using electromagnetism-like mechanism algorithm.

Calculation method of Water Injection forward modeling and inversion process in oilfield Water Injection network
2018Co-Authors: Long Liu, Wei LiuAbstract:A forward modeling and inversion algorithm is adopted in order to determine the Water Injection plan in the oilfield Water Injection network. The main idea of the algorithm is shown as follows: firstly, the oilfield Water Injection network is inversely calculated. The pumping station demand flow is calculated. Then, forward modeling calculation is carried out for judging whether all Water Injection wells meet the requirements of Injection allocation or not. If all Water Injection wells meet the requirements of Injection allocation, calculation is stopped, otherwise the demand Injection allocation flow rate of certain step size is reduced aiming at Water Injection wells which do not meet requirements, and next iterative operation is started. It is not necessary to list the algorithm into Water Injection network system algorithm, which can be realized easily. Iterative method is used, which is suitable for computer programming. Experimental result shows that the algorithm is fast and accurate.A forward modeling and inversion algorithm is adopted in order to determine the Water Injection plan in the oilfield Water Injection network.
