摘要： A process for purifying nitrobenzene-contaminated wastewater stream WW1 includes stripping WW1 with stripping gas SG1 in a stripping column to obtain wastewater stream WW2 containing reduced concentration of nitrobenzene relative to WW1 (cNB,WW2), and purifying WW2 in a wastewater treatment plant, wherein a target value (cNB,WW2,TARGET) is specified for the nitrobenzene concentration in WW2. A set of linear mathematical relationships is stored in a database for a combination of boundary conditions of nitrobenzene concentration in WW1, temperature of WW1, and temperature of SG1. This set defines a range of concentrations of nitrobenzene in WW2 and includes a mathematical relationship corresponding to cNB,WW2,TARGET, a mathematical relationship for a value of cNB,WW2 corresponding to 98% of cNB,WW2,TARGET, and a linear mathematical relationship for a value of cNB,WW2 corresponding to 102% of cNB,WW2,TARGET. The concentration of nitrobenzene is controlled in WW2 (cNB,WW2) by adjusting the flow rate of SG1.

摘要： A rotary evaporator includes a sample flask having a reservoir for receiving a sample and a neck in communication with the reservoir. The neck extends along an axis and a purge tube extends within the neck of the sample flask along the axis. The purge tube includes a distal end and at least one opening formed in the purge tube at the distal end, the distal end being closed. Purge gas is supplied to the purge tube and injected into the sample flask via the at least one opening. The purge tube is movable along the axis via an actuator, between a retracted position, where the distal end of the purge tube is situated in the neck of the sample flask, and an extended position, where the distal end of the purge tube is situated in the reservoir of the sample flask.

摘要： A process for hydrocracking a petroleum feedstock involves:
(a) hydrocracking the feedstock to obtain a hydrocracked effluent;
(b) liquid/gas separation of the effluent to obtain a gaseous effluent and a liquid effluent;
(c) fractionating the liquid effluent at a pressure P1, producing a first distillate and a first residue,
(d) recycling a first portion of the first residue to hydrocracking,
(e) rectifying a second portion of the first residue at a pressure P2 lower than or equal to the pressure P1, to obtain a secondary distillate, a secondary residue and a vapor stream,
(f) purging a portion of the secondary residue, and
(g) recycling all or part of the secondary distillate to hydrocracking.-

摘要： A process for the recovery of a light boiler and a heavy boiler from a vapor stream, where the process includes: A1) introducing a vapor stream containing a light boiler and a heavy boiler into a column at a point at the bottom of the column, A2) withdrawing a vapor stream, enriched in the light boiler, from the top of the column, A3) withdrawing a liquid stream, enriched in the heavy boiler, from the bottom of the column, and splitting the stream into a partial stream and a partial stream, A4) recycling the stream back into the column at a point above the column, wherein the stream is kept essentially adiabatically during the recycling, A5) withdrawing a stream, enriched in a middle boiler, from the middle section of the column and splitting the stream into a partial stream and a partial stream, A6) cooling the partial stream in the heat exchanger to provide the cooled stream and recycling the stream as stream back into the column at an introduction point below the top of the column, and A7) withdrawing the partial stream, enriched in the heavy boiler, and the partial stream, enriched in the middle boiler.

摘要： A refiner device for refining of a liquid, wherein the refiner device includes a housing provided with a liquid inlet for unrefined oil or fuel, a liquid outlet for refined oil or fuel, an air inlet for supplying a flow of air into the housing, and an air outlet for discharging air and contaminants removed from the liquid. The refiner device further includes a liquid receiving plate arranged inside the housing, the refiner device arranged such that when liquid has passed through the liquid inlet during operation of the device, the liquid is contacted with an upper surface of the liquid receiving plate before it reaches the liquid outlet, and at least one heating element arranged to directly or indirectly heat the liquid while the liquid is in contact with the liquid receiving plate. The refiner device further includes a hollow air-guiding member arranged at the liquid receiving plate.

摘要： A biocidal treatment evaporates a liquid having biocidal properties. An absorption organ has absorbent strips suited to retain the liquid, each absorbent strip having a top first end and a bottom second end, The liquid is injected into the first end of each absorbent strip, the liquid flowing by gravity along the absorbent strip towards the second end, the liquid having biocidal properties being injected at a predetermined flow rate. The liquid is evaporated by producing a gas flow directed towards the absorption organ at a temperature below 50° C.

摘要： An air stripper apparatus is disclosed which incorporates a plurality of trays that are removably supported within a cabinet. A plurality of downcomers are also fixedly disposed within the cabinet, rather than on the trays. Removing the downcomer from each tray enables a simpler, lighter and easier to clean tray to be constructed.

摘要： An apparatus for extracting contaminants from a contaminated material, such as contaminated soil and animal manure, includes an extraction tank having an interior, a heating element that is adapted heat the contaminated material to a temperature where contaminants in the contaminated material are released therefrom to the interior of the extraction tank, and an agitator that is adapted to agitate the contaminated material as it is being heated by the heating element. The apparatus also includes an air pump that generates a series of positive pressure air pulses at an outlet thereof and a series of negative pressure air pulses at the inlet thereof. The apparatus further includes one or more contaminant retaining mechanisms, such as a sediment holding tank, a fluid holding tank, and a gas filter. The interior of the extraction tank, the air pump, and the contaminant retaining mechanisms are connected in a closed loop air circulation system such that the contaminants that are released from the contaminated material are stored in the contaminant retaining mechanisms.
