Coke Quenching Plenum Equipment Corrosion and Its Dependents on the Quality of the Biochemically Treated Water of the Coke-Chemical Production

Abstract

Steel corrosion processes that occur due to the effects of the biochemically treated water in coke quenching plenums have been studied. Model investigations into the processes of the corrosion failure of carbon St. 3 steel and alloyed 18Х1MF steel were carried out to study the behavior of the metal exposed to the action of the primary but treated water used for the coke quenching after the metal is heated to 373 K and 773 K. Different types of the corrosion that results from the contact of the carbon steel and alloy steel with the sodium hydroxide biochemically treated water of the coke-chemical production have been described. It was shown that the corrosion failure of the steels results from the formation of the films of hydrated iron oxides that appear in all the test media and these films show different behavior of adhesion to specimen surfaces. It was proved that the water treatment results in a certain decrease of the values of the mass and in-depth corrosion factors for St.3 and 12X1MF steels, however it fails to produce an essential effect when the steel is in constant touch with hot water.

Experimental Evaluation of an Empirical Equation in a Gaseous Flow

“…( 3) in Eq. ( 2) and ordering we have: (4) In this last equation, the superior calorific value and the coefficient depend on the physical characteristics of the gas that circulates for the pipe, while K 1 depends only on the diameter of the pipe. Observation:…”

“…3 Therefore, the selection of pipe material grades with higher corrosion resistance and the treatment of the circulating water have been considered as preventive measures. 4 In the specialized literature, empirical equations such as those of Darcy Weisbach, Colebrook-White, Renouard, Weymouth, Cox, and others, have been identified; whose purpose is to provide the methodology to follow to estimate the pressure drop of gas flows. Likewise, and as the basis for this study, we highlight the empirical equation of Dr.…”

Modeling of Coke Distribution in a Dry Quenching Zone

“…Optimization of the CDQ process will allow minimizing the abovementioned disadvantages. Works on improving the CDQ process are carried out in various directions. − One of the directions for such optimization is the technology development for the uniform distribution of coke in the quenching chamber. Therefore, the research purpose described in the article is to find a solution in which each class of coke will be evenly distributed across the section of the quenching chamber.…”

Modern Use of Biochar in Various Technologies and Industries. A Review

“…Metallurgical production requires the use of carbon and hydrogen-containing reducing agents such as coke, coal and natural gas. The quality of coke is one of the main parameters that determine the progress and results of blast furnace smelting [6][7][8] . Given that coke is the most expensive component of the cast iron charge, the task of reducing its consumption is always relevant.…”
