摘要： A method and a system for recycling spent ethylene or propylene glycol recovered from aircraft deicing solutions is described. The recovered spent ethylene or propylene glycol contains water and other undesirable substances which require to be removed to produce a solution free of these substances which can be further processed to remove substantially all of the water content and to blend-in additives required to certify the final glycol solution for aircraft deicing. The method and system employs a computer controller for continuous automatic batch processing of the spent glycol, including, in combination, filtering, distillation, blending and testing in specific sequences and achieves an improved quality recycled glycol of a purity of at least 99.5% and preferably between 99.6% to 99.9% glycol concentration.

摘要： A system of fluid sterilization is provided, which incorporates a heating section to heat pressurized fluid above prescribed thresholds for temperature, pressure, and duration (e.g., dwell time) to achieve desired levels of sterilization, including a heat exchanger to both (a) preheat fluid prior to entering the heating section and (b) cool outflow of the heating apparatus, in which fluid travels through the apparatus by operating valves forward and aft of the heating section in a controlled sequence to facilitate flow through the system while maintaining prescribed pressure and temperature profiles. The system operates within prescribed ranges of pressure and temperature to achieve the desired level of sterilization without need of maintaining a fixed temperature or a fixed pressure within any portion of the system, including the heating section.

摘要： An apparatus, system and method are provided for controlling fluid flow through a vacuum chamber of a dehydration system, the vacuum chamber having a temperature sensing device operative to measure a temperature of a fluid in the vacuum chamber. A temperature difference between a temperature setpoint for the fluid and the measured temperature of the fluid is determined, and fluid is recirculated through the vacuum chamber while the temperature difference is greater than a predetermined temperature difference. While the temperature difference is less than the predetermined temperature difference, the fluid is recirculated through the vacuum chamber for a predetermined time period, and upon the predetermined time period expiring inhibiting recirculation of the fluid through the vacuum chamber.

摘要： A method and a device for manufacturing lactide, whereby crude lactide, being prepared by means of depolymerization of lactic acid oligomers, is purified by means of a distillation step. The prepared crude lactide is maintained for a period of at least 5 hours in a reaction vessel at a temperature between 97° C. and 200° C. prior to the distillation step. Keeping the lactide during a period of time in a reaction vessel leads to a decrease of the lactic acid content and an increase of the lactic acid oligomer concentration, so that the resulting crude lactide can be more efficiently purified during subsequent distillation. A pre-distilling step gives additional advantages.

摘要： A method for precisely predicting phase equilibrium from existing phase equilibrium data on the basis of a wide range of phase equilibrium data including binary vapor-liquid equilibrium data; a method or apparatus for designing or controlling a component separator or a refiner using the prediction method; and a program for designing this design or control apparatus. Binary phase equilibrium measurement data is used to calculate an index of proximity ratio to critical points and infinite dilution pressure gradients. The obtained index is correlated with the infinite dilution pressure gradients to newly calculate infinite dilution activity coefficients from the respective index to infinite dilution pressure gradients correlations. The obtained infinite dilution activity coefficients values are used to predict phase equilibrium. Thus, the obtained values are used to design or control a component separator or a refiner, such as a distillation column.

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.
