Nitriding also may be done by gas or liquid methods. In carbonitriding, the steel may be exposed to a carrier gas containing carbon and as much as 10% ammonia (NH 3), the N 2 source, or a molten cyanide salt, which provides both elements. NH 3, from gaseous or liquid salts, is also the N 2 source for nitriding. Although low- and medium-carbon. Under standard conditions, methane is thermodynamically unstable above °C and decomposes to solid carbon and hydrogen. At appropriate CH 4 /H 2 ratio and temperature, carbon activity in the methane-containing gas phase can be well above unity relative to graphite, which provides favorable thermodynamic conditions for reduction. To maintain.

Gas phase mass transfer on top-blown liquid surfaces by Xuegang Dai Download PDF EPUB FB2

Studies of gas phase mass transfer between top-blown gas jets and liquid surfaces in the non-splashing mode were carried out using two room temperature processes:. There have been extensive heat transfer studies of impinging gas jets on solid surfaces, but few on impinging gas jets on a liquid bath.

In this paper, air-jet-induced transport in a heated liquid bath is by: 4. In the case of V oil /V w = (–) and Q T +Q B from 30 to (10 −3 Nm 3 /min), there was a positive correlation between liquid/liquid and gas/liquid mass transfer rates in spite of large scattering values.

The increasing rate of the liquid/liquid mass transfer to the gas/liquid one at D= Gas phase mass transfer on top-blown liquid surfaces book was larger than that at D= : Yuho Kawabe, Md. Azhar Uddin, Yoshiei Kato, Min Oh Seok, Sang Beom Lee.

Introduction. All operations in process metallurgy involve complex phenomena comprising momentum, heat, and/or mass transport. Transport phenomena, i.e., fluid flows, heat transfer, and mass transfer, play a dominant role, since their respective laws govern the kinetics of the various physical phenomena occurring in metallurgical processing : Kinnor Chattopadhyay, Roderick I.L.

Guthrie. The oxidation kinetics of molten copper sulphide were investigated by quantitative measurements and qualitative observations.

Off-gas analyses for SO2 and 02 were conducted to determine the oxidation rates of approximately gram samples, ofmolten % Cu2S. The molten sulphide was held in alumina crucibles (approximately 44 mm diameter and 75 mm height), and top Cited by: 8.

These phenomena comprise chemical reactions in liquid metal, slag, and gas phases and at their interfaces, heat effects, and fluid flow and mass transfer phenomena in different reaction zones as well as in the entire system. Oxidation of carbon and other impurities in the iron melt is controlled mainly by mass transport from the oxygen jet to.

Subsequently, CO 2 reacts with carbon in an iron droplet at the metal-gas interface, and the formed CO is transferred back to the slag-gas interface via the gas phase. It should be noted that there is disagreement among researchers about the description of the mechanisms and the rate-controlling step(s) under different operating conditions [ 26 ].

To determine the influence of volumetric gas flow rate on the kinetics of the oxidation reaction and to study the gas phase mass transfer, Gas Jets Impinging on Liquid Surfaces ^ 17 ^Convective Gas Liquid Contact-Top-blown and bottom-blown jets in bath smelting are the most common metallurgical examples of gas-liquid.

ISASMELT technology has been applied to lead, copper, and nickel smelting, and by fifteen plants were in operation in ten countries, with another five in various stages of development.

The installed capacity of the operating plants in was over 8 million tonnes per year (t/y) of feed materials, with additional capacity to come on line in and The temperature-composition curves for each phase in two-phase equilibrium are the two curves that separate the single phase from the two-phase region (see Figure ).

At temperature T 2, for instance, the liquid phase is richer in component B and the gas phase is richer in component A. The principle of distillation relies upon this fact.

Extractive metallurgy is the art and science of extracting metals from their ores and refining them. The production of metals and alloys from these source materials is still one of the most important and fundamental industries in both developed and developing economies around the world.

In a process for the gasification of solid carbonaceous material such as coal, powdered coal is top-blown onto a molten iron bath stored in a furnace through a non-submerged lance toward a hot spot formed by means of a jet of oxygen and steam top-blown through a non-submerged lance, coal being blown by means of a carrier gas, and flux is.

The mass transfer coefficient in the metal phase is k met in (m s −1). C scrap and C HM are the carbon concentrations in the scrap and hot metal in (wt.%). C liq describes the carbon concentration on the liquidus line. The density of the liquid hot metal is ρ liquid and of the scrap is ρ scrap, both in (kg m − ³) [3,27].Cited by: 2.

Calcium hypochlorite, Ca(OCl)2, and calcium chloride, CaC12, are formed. All containers have one or two internal pipes, so that either the gas or the liquid may be drawn.

If the gas is drawn, heat must be supplied to make up for the heat of vaporization, or else the process is very slow.The energy transfer occured when the gas phase entered into the liquid phase at a certain speed. The flow velocity in the upper part of the oxygen lance zone was relatively high while the flow velocity was slow on both sides in the bath.

With gas phase entering into liquid phase continuously, the distribution of velocity field and momentum. Domain decomposition (DD) is a powerful approach to numerically solve partial differential equations, and it has become popular and indispensable in simulations of fluid flows, especially those that arise from models of the real world that require large-scale, parallel computation.

Domain decomposition methods (DDMs) were originally introduced for problems Author: H. S. Tang, R. D. Haynes, G. Houzeaux.
