When designing ports, one important task is to predict sinoimeri port areas and approach channels sandy or pebbly silt. On the basis of this forecast are determined by the methods of protection from sinoimeri, as well as the frequency and volume of maintenance dredging works. Out at sea the river flow becomes turbulent inertial jet. Friction on the bottom and the interaction with sea water leads to an overall reduction of jet velocity and its spreading. An important regularity is also spreading muddy river flow on the surface of the denser seawater. This creates conditions for rapid deposition of large fractions of the sediment on the bottom. The bulk of the sediment particles larger than 5 mm is deposited on the surface of the river bar and further transported along the shore wave energy currents. Outside of the bar shall be made only fine-grained material. The particle size of sediment deposited on the bottom outside of the bar decreases sharply with depth. Thus, sinoimeri of harbors and access channels is mainly suspended river sediments. To calculate the distribution of the river flow, in the coastal zone in the presence of long chore currents developed a special method that implements the theory of turbulent planar jet in a drifting thread. The solid portion of the jet flow that enters the waters of the port or channel as a result of increasing depth and, consequently, reduce turbidity settles, causing shoaling waters. The example of calculation of sinoimeri berth 1a in the port of Tuapse by solid flow of Tuapse river.

Energy conservation in the design of a chemical plant is one of the most important considerations. In addition, to determine the minimum amount of hot and cold energy needed for a process is one of the main computations of determining the amount of stored energy. The heat integration (energy integrating) is an important factor in economic designs. In this paper, phases 9 and 10 of the gas condensate stabilization process of the South Pars gas are optimized using the integration design method. The results obtained showed the modified heat exchanger network, removal of existing both air fans, recovery of 2.5 MW of electricity and reduced operating costs.

The effect of the shape of impellers on the wastewater treatment process is investigated in this research. Wastewater from the desalination unit of petrochemical industry is used in treatment tanks. Experiments are held with three different types of impellers in the treatment tanks and the amounts of chemical oxygen demands, biological oxygen demands.

The article contains mathematical model and simulation of dynamics of raising the height of the bell from the gas mass flow. The results obtained for the three sizes gazgoderov GM-600 GM-6400 GM-24000. Assuming the law changes the mass flow rate of gas obtained by the functional dependence of the height of the lifting bell on the initial state.

The article contains mathematical model and the simulation results of liquid outflow from the reservoirs at alternating dynamic level. The results obtained for the three sizes of vertical steel tanks – PBC PBC-1000 -5000, -20000 PBC and horizontal tanks, wagon – tanks of 50 m3 and 100 m3 and 150 m3. Obtain a functional dependence of the liquid outflow from the tanks, depending on the diameter of the outlet nozzle. For horizontal tank volume of 50 m3 is given assessment of the impact of the coefficient of flow at the time of expiration.

Fortunately, in regions of greater potable and drinking water shortage like Middle East, renewable energies such as solar energy is more abundant during the year. The desalination method in this solar desalination still is evaporation distillation. Basically this solar desalination still is a batch stage for every day operation with saline wastewater. This paper describes the solar desalination still, discusses the used method for distillation and represents the experimental results, finally. The results show the feasibility of using the solar still.

With helping of soft "Thermodynamic" there was numerical researching of the thermodynamic combustion's parameters of watered gasoline for conditions of carbureted engine as function of coefficients of oxidizer's surplus and water ballast. It is shown that the water ballast of about 5 % can be useful, as it gives a stoichiometric combustion of nearly 10 percent increase in RT while reducing the CO by 42 %.
