REFINERIES / OIL & GAS FACILITY – Deha Tech. An oil refinery or petroleum refinery is an industrial process plant where crude oil is processed and refined by complex chemical engineering processes, into more useful products such as petroleum naphtha, gasoline, diesel fuel, asphalt base, heating oil, kerosene, and liquefied petroleum gas.
Wind energy is used in wind mills which converts the kinetic energy of the wind into mechanical or electrical energy. The kinetic energy of wind can be used to do mechanical work like lifting water from wells or grinding grains in flour mills. It can also be used to rotate the turbines of generators to produce electricity.

Cement Manufacturing. 277. Air Emissions. A maximum emissions level of 50 milligrams per normal cubic meter (mg/Nm. 3), equivalent to a maximum of 0.2 kg/t of clinker, for particu-lates in stack gases under full-load conditions is to be achieved. This emissions level is based on values that are routinely achieved in well-run plants.

Recycled concrete aggregate (RCA) possess high water absorption, due to the porosity of the attached hardened cement paste they contain. Fine particles of RCA are composed of larger amounts of hardened cement paste, which makes their valorization even more difficult in concrete or mortar. One way to valorize these fine particles could be to use …

The reported average mine water consumption for slurry tailings in arid climate is between 0.4 and 0.7 m³/tonne. The estimated mean required make up water from the developed model in this reaserch was 0.70 m³/tonne. Water withdrawal in dry climate conditions can decrease to 0.18m³/tonne when a filtered tailings option is implemented.

The designer should size the diameter of the upward sloping portion of the exhaust piping – between the water lift muffler and the highest system elevation – such that the velocity of the exhaust-gas-and-water droplet mixture is not below 5000 ft/min (25.4 m/sec), with the engine running at rated load and speed.
The liquid percentage at 1450 0 C can be estimated using the formula. % Liquid content (1450 0C) = 3.0 x A+2.25 x F+S. Where A=Al 2 O, F=Fe 2 O 3, S= MgO+K 2 O+Na 2 O+SO 3 In Clinker. The normal range of liquid phase is 22-27%. Burnability is a reference value for raw meal indicating how difficult it is to burn.

material is separated in a classifier that is re-circulated and returned to the mill for additional grinding to ensure a uniform surface area of the final product. (Coito et al., 2005, and others.) Figure 1 presents a diagram of the cement manufacturing process using a rotary kiln and cyclone preheater configuration.

About 4 t of ore or tailing is ground in "chanchas" (without mercury) and agglomerated in a cement mixer with 12 kg of cement, 1 kg of quicklime, 500 L of water and 3–4 kg of sodium cyanide. The pelletized material proceeds to a stack and cures for 4 days covered with plastic before being added to the 15 to 20-t percolation tanks for 10 ...
The EZ30D engine had sequential, multipoint fuel injection via 'air assist' fuel injectors; the injection and firing order were 1-6-3-2-5-4. Dual air/fuel sensors were used to monitor fuel mixture after combustion and continual adjustments were made to reduce exhaust gas emissions.
A method for treating cement kiln dust is provided. The method includes the steps of receiving cement kiln dust (CKD) from a kiln; heating the collected CKD; forming a gas stream of vaporized metal and CKD by sufficient heating to separate at least one heavy metal from the collected CKD stream to create a cleaned CKD stream and a metal stream; providing a water soluble alkaline …

Particulate matter emission from a stack attached to the kiln and raw mill in a cement plant was studied. Elemental (As, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb and Zn) and ionic (Ca 2+, NO 3 −, SO 4 2−) composition and particle size distribution of stack particulates, principal raw materials and products were determined.The feed rates of raw meal were found to be 144 and …

Grinding down biomass helps to reduce the horsepower the pellet mill must produce. If the biomass is high in moisture, it must be dried to approximately 10 percent moisture content.
