Abstract: The Industrial solid waste samples were collected at the outlet of release channel of the “Oil and Gas Industry” at Kakinada, air-dried and was brought to the laboratory. The soil amendments were prepared for as Control, Amendment 1,2,3 and 4. The RGR values of Control plants recorded on 21-51, 51-81 and 81-95 day growth periods were 0.0921, 0.0460 and 0.0095 mg/g/d respectively. Both control and A1, A2, A3 and A4 soils showed an insignificant decreasing trend in RGR over the harvesting periods. The relative growth rate in A1, A2, A3 and A4 soils did not exhibit any definite pattern of variation. The high toxicity levels of the Copper, Zinc, Iron and Manganese heavy metals were accumulated in the industrial solid waste. The results of this study stress the need for environmental awareness, adequate regulations and proper management of waste sites by the local municipal authorities and Pollution control board take the necessary actions to control Industrial solid waste disposal site on the Kakinada, Andhra Pradesh and India.

Abstract: Investigated regularities and manifestations of the elastic deformations of the polymer flow under conditions are close to that of the real flows of the fire hoses at oilfield territories. The data obtained in this study shows that it is necessary to consider the possible effects of the elastic deformations when solving the problem of drag reduction of the fire suppressing liquid in the pipeline at oilfield territories by injecting the polymer solutions in the boundary layer and for the development of the optimum system of the introduction. The decreased effect in diminution of resistance to liquid flow when feeding polymer solution into boundary layer of a fire-hose is the result of combining deformation effect of longitudinal hydrodynamic field available in a feeding system and molecular-concentration properties of polymer solution. There have been outlined ways of increasing the effectiveness of systems for feeding polymer solutions into fire-hoses, and hence, fire-fighting systems with water, which increase the fire protection degree at oilfield territories and decreases the environment pollution with combustion products and heat.

Abstract: It has been analyzed solution to the problem of definition eccentric location of the drill string in the hole using analytical studies and modern systems of mathematical computer modeling. Practical implementation of technological problem solution was represented as calculated parameters of the formation and changes in the area of stagnant zones in the cross section of the annular space hole in certain baseline characteristics of the process of washing. As a result, studies have found that at lower eccentric placement of both direct and deformed drill string in the well drilling mud flow looks like sickle core flow. The maximum speed of mud while inside the nucleus, and the minimum - in the contact zones flexible pipe and the borehole wall. This change dependencies hydraulic pressure loss pumping mud pump flow rate and distribution of nuclei along the axis of the drill string at its eccentric location in the borehole. It has been determined the conditions of dead mud zones formation in the annular space and offered solutions to solve this problem.

Abstract: In this study, the adsorption of reactive yellow dye which is one of the most commonly used soluble dyes in textile industries was studied using modified wheat straw, the surface of raw wheat straw was modified with a cationic surfactant CTAB. to understand the adsorption behavior of the reactive yellow, dye the adsorption kinetics and the adsorption isotherm studies have been investigated. Batch experiments was carried out with an initial concentration of 10 mg/L with 0.5 gm of adsorbent to study the contact time of equilibrium and then the adsorption mechanism process using three kinetic models; Pseudo-first, second order and intra-particle model. Isotherm studies was carried out at three different adsorbent amounts (0.1, 0.2, 0.4, 0.6, 0.8 and 1.0) gm to predict the type of adsorption process on the surface (chemical or physical) using three isotherm models; Langmuir, Freundlich and BET models. The results showed that the pseudo-second order is best fitted, intra-particle diffusion kinetic model fitted well to experimental data and is not the only controlling step of adsorption rate, and the adsorption isotherm follows both Langmuir and Freundlich models referring to the chemical adsorption.
