摘要： PROBLEM TO BE SOLVED: To improve the convergence in the simulation work for simulating a distillation apparatus equipped with a combined distillation tower. SOLUTION: The simulation of the distillation apparatus equipped with the combined distillation tower is carried out using a simulation program for the distillation apparatus equipped with a main tower and a side tower. The simulation work is carried out by inputting the liquid distribution ratio of the combined distillation tower as the liquid distribution ratio of the flow rate of each liquid which distribution ratio has been set for distribution the liquid descending from the top of the main tower into the liquid descending through the feed side and the liquid descending through the side cut side and calculating the steam distribution ratio of the combined distillation tower corresponding to the liquid distribution ratio for distributing the steam ascending from the tower bottom into the steam ascending through the feed side and the steam ascending through the side cut side.

摘要： PROBLEM TO BE SOLVED: To prevent a product from being affected in terms of color, odor, and the like by recovering the product in which impurities do not remain. SOLUTION: This distillation apparatus has a column main body, an internal partition wall, the first distillation part to which an original liquid adjusted by adding an additional component is fed through a feed nozzle 41, the second distillation part, the third distillation part, a condenser 81 disposed on the column top, the first discharge system which is disposed at the column side for discharging the liquid rich in high-boiling point component, the second discharge system which is disposed at the column bottom for discharging the liquid rich in the additional component as a bottom liquid and an evaporator 82. The boiling point of the additional component is made higher than that of the high- boiling point component. In this case, since the degenerated component to be formed by decomposing the high-boiling point component is accumulated in the vicinity of the column bottom, the degenerated component is not brought into contact with the high-boiling point component in liquid states. Thus, the product is not recovered as it contains the degenerated component or the like as impurities.

摘要： PROBLEM TO BE SOLVED: To bring a liquid and steam into sufficient contact with each other. SOLUTION: This liquid collecting apparatus comprises an outer box, an inner partition dividing the inside of the outer box to form a plurality of chambers neighboring one another, a collector box 72 forming a liquid collecting channel 91 along the inner circumferences of the outer box and the inner partition, and a plurality of collector laminas 93, 94 installed on the collector box 72 at prescribed pitches in parallel to one another. Each lamina is provided with an inclination part 74 and a groove part 75. One end of each groove part 75 is set face to face to the outer box side of the liquid collecting channel 91 and the other end is set face to face to the inner partition side of the liquid collecting channel 91. Since the flow of the liquid and the flow of steam do not get uneven, the liquid and steam can sufficiently be brought into contact with each other in the upper and the lower chambers.

摘要： PURPOSE:To collect a crude low-boiling oil contained in a coke-oven gas in a high yield, by feeding a coke-oven gas from a bottom portion of a column packed with a thin and lightweight metallic stacked packing material by lamination and, at the same time, applying an absorbent oil from the top thereof for countercurrent contact. CONSTITUTION:At least one packed column packed with a thin and lightweight metallic stacked packing material by lamination is used in collecting a crude low-boiling oil contained in a coke-oven gas. A coke-oven gas is fed from the bottom of the column while an absorbent oil is applied from the top thereof, thereby conducting countercurrent contact. Examples of the thin and lightweight metallic stacked packing material include one having a specific surface area of about 250m /m , a weight of about 100kg/m , and a porosity of 95% or more. The packing material may be made of structural carbon steel, stainless steel, titanium alloy, or the like. However, it is pref. to use stainless steel having excellent resistance to the absorbent oil.

SOLUTION: This liquid collecting apparatus comprises an outer box 70, an inner partition 23 dividing the inside of the outer box 70 to form a plurality of chambers neighboring one another, a collector box 72 forming a liquid collecting channel 91 along the inner circumferences of the outer box and the inner partition, and a plurality of collector laminas 93, 94 installed on the collector box 72 at prescribed pitches in parallel to one another. The collector box 72 and the collector laminas are previously assembled and the collector box 72, the outer box 70, and the inner partition 23 are engaged one another. In this case, since the collector box 72 and the laminas are previously assembled, collectors 62, 65 can easily be attached to the outer box 70. Consequently, since it is no need to assemble the collectors 62, 65 in a distillation tower, the installation work can be simplified.
