摘要： A liquid sample 3 held in an open container 2 and including a volatile solvent, is evaporated by continuously removing inert gas rich in vapor by means of a suction tube 5 whose open end is held close to the top surface of the liquid. Vapor in the gas is then extracted in a refrigerated condensing vessel 6, from where the purified gas is fed by a pump 7 for recirculation back into a sealed chamber 1 in which the container is mounted. In a modification, the inert gas is fed directly through a nozzle 17 into the container 2 wile the gas/vapor mixture is extracted from the chamber 1 for recirculation, after passing through a condenser 6 or the like.

摘要： A control method and apparatus for regulating the rate of vapor flow in the two adjacent sections of a dividing wall fractional distillation column are presented. The liquid level on a tray at the top of each section is used to control the rate of vapor flow through the tray. The liquid level is controlled by measuring the pressure differential across the tray in each section and varying the flow of liquid to this tray in response to the differential.

摘要： Problems generated by heat transfer through the vertical dividing wall of a trayed “dividing wall column” and into a downcomer of a tray are mitigated by providing a separate vertical isolation wall between the downcomer and dividing wall. The isolation wall forms one side of the downcomer and is spaced a short distance outward from the dividing wall to form an isolation volume which thermally insulates the downcomer from the dividing wall. The added wall is parallel to the dividing wall and supplants the dividing wall as a part of the downcomer. It eliminates a need to insulate the dividing wall.

摘要： The present invention is directed to an apparatus and method for the distillation of a readily polymerizable vinyl aromatic compound employing a polymerization inhibitor. The vinyl aromatic compound is subjected to distillation in at least one fractionation column having at least one reboiler for maintaining the bottoms of said column at a proper temperature. The reboiler includes a heating section and a vapor phase section. The bottoms fraction from the fractionation column is cycled to the reboiler and subjected to heat to vaporize at least a portion of the bottoms fraction to form a vapor phase in the vapor section, A slip stream of the bottoms fraction is introduced to the vapor phase section of the reboiler. The slipstream contains polymerization inhibitor that had been added to the process at the fractionation column. The invention reduces fouling at the reboilers. The slipstream is optionally introduced to the reboiler using one or more spray nozzles. The polymerization inhibitor is added to the fractionation column in sufficient amounts to maintain a concentration of at least 400 parts per million by weight in the bottoms fraction.

摘要： A perforated tray without downcomer in accordance with the present invention satisfies following conditions: (a) The hole has a diameter of 10 mm to 25 mm. (b) Two adjacent holes are spaced by a distance of 1.2 d to 3 d, measured between the two centers. (c) The tray thickness is 2 mm to 8 mm. (d) The opening ratio is 10% to 30%. A perforated tray tower without downcomer fitted with two or more such perforated trays without downcomer in accordance with the present invention satisfies following conditions: (g) Perforated trays are spaced by a distance of 0.1 D to 0.5 D (D denotes the tower diameter). (h) The levelness of each perforated tray is 8 mm or less. (i) If a plurality of perforated trays are used at the same stage, the two most closely located holes that respectively belong to adjacent perforated trays are spaced by a distance of 50 mm to 150 mm, measured between the two centers. By using the perforated tray tower without downcomer, an easily polymerizable compound, such as an (meth)acrylic acid, or a liquid containing such an easily polymerizable compound can be distilled in a stable manner over an extended period of time with the formation of polymers being effectively prevented.
