Title: Distillation plus ion exchange processing of a brine stream
Inventor: SCOGGINS LACEY E
IPC: B01D3/40
Filed: 1991-11-14
Abstract: ABSTRACT   A method for recovering a liquid diluent having a low salt content from an organic/aqueous phase mixture which contains significant quantities of the diluent, an alkali metal salt, and water comprises an integrated process which joins extractive distillation and ion exchange steps with a subsequent reaction for the conversion of an alkali metal hydroxide.  In the initial step the diluent is extracted from the original mixture employing a suitable extractant material.  The extract from the initial step containing diluent, extractant material, along with reduced quantities of water and salt, is passed to an ion exchange column for conversion of the alkali metal salt to its hydroxide.  In a following fractional distillation dewatering column the extractant material begins to react with the alkali metal hydroxide to form an alkali-metal salt of aminocarboxylic acid which can pass harmlessly through the dewatering column for removal in further following fractional distillation step.

Inventor: STUDER DAVID W
IPC: C07C31/04
Filed: 1992-02-24
Abstract: Methanol is produced frog synthesis gas comprising hydrogen, carbon monoxide, and carbon dioxide in a two-stage liquid phase reactor system. Each reactor is operated in an optimum temperature range to maximize methanol productivity, and once-through product conversion of up to 9.1 moles methanol per 100 moles of synthesis gas can be achieved with reasonable catalyst utilization. Overall catalyst utilization is increased by countercurrent catalyst transfer. In an alternate mode of operation, the liquid phase reactor system is integrated with a coal gasification combined cycle (CGCC) power generation process wherein the unreacted synthesis gas is used as fuel in a gas turbine-driven electric power generator. Operation of each liquid phase reactor in the optimum temperature range maximizes the available heat of reaction which is recovered as steam; the steam is utilized in the gas turbine combustor or the CGCC steam turbine. Methanol from the liquid phase reactor system can be used as peak shaving fuel for the gas turbine.

Abstract: The invention relates to a method for thickening and clarifying fine particle suspensions, wherein the suspensions are thickened and clarified in combination with a back-pulse filtration process. The method is characterized by partially submerging one or more filter modules in the fine particle suspension concerned, in open vessels or reservoirs. The suspension is backpulse filtered in these open vessels or reservoirs with the aid of the filter modules. The invention also relates to a filter module which includes one or more parallel working, vertical hollow-tubular filters, and a device for delivering liquid and optionally air to the filter module and removing the liquid and air therefrom during filter operation, this device being common to all filters. The filter module is characterized in that the filters are mounted in a plate and that the plate is covered by an easily opened lid which, when closed, seals against the plate. The lid also includes connectors through which liquid and air are delivered to and removed from the module. <IMAGE>

Filed: 1992-05-05
Abstract: ABSTRACT OF THE DISCLOSURE         A mobile racking system for installation in a trailer van which is fitted on the inside sidewalls with a number of load retaining strips at different elevations to define different elevation loads.  A number of clamping bracket assemblies are releasably attached to the retaining strips, each assembly being provided with a releasable engagement device for accepting a C-shaped track member to provide a pathway for accepting and supporting a carriage in the form of a roller pallet.  The releasable engagement device has a cam member for securing the C-shaped track member to the load retaining strip.  The roller pallet extends substantially across the width of the trailer van, the roller pallet having at least on one side, a pair of rollers which are rigidly secured to axles which are adapted to move laterally on the pallet to accommodate differences in the spacing between the two side walls of the trailer.  The clamping bracket assembly has a "["-shaped body having upper and lower arms joined by a bight.  A sleeve is secured to the bottom of the lower arm and extends towards the bight.  A releasable engagement device, cooperatively supported by the sleeve, supports a cam member. By rotating a handle to an unlocked position, the clamping bracket assembly can be releasably fastened to the load retaining strip.  In the mid-position of the handle, a camming portion of the cam member is raised upwardly to prevent accidental dislodgement of the clamping bracket assembly, and in the locking position, a high camming surface is wedged between the body of the clamping bracket assembly and the load retaining strip to lock the C-shaped track member in the bracket assembly.

Abstract: A  steering  system  is  provided  for  steering  a plurality of conveyor vehicles connected together in the form of a train.  The vehicle has a first pair of wheels which can be steered by an operator as the train moves.   There are further pairs of steerable wheels connected to the second and subsequent vehicles in the train and supporting same.  There are hydraulic cylinders for steering each of the pairs of steerable wheels on the second and subsequent vehicles and a control mechanism for controlling these cylinders in order to set the steering angle of each further pair.   This control mechanism includes means for determining the current steering angle of the first pair of wheels and generating an electrical signal indicative thereof and means for storing a series of these electrical signals as the train is travelling.  Further means determine the amount of time the wheels in the train have been travelling and there is a calculator for determining the location of each of the further pairs of wheels on the basis of the determined travel time.   A second electrical signal is generated for each further pairs of wheels in order to control its respective hydraulic cylinder and thereby set the steering angle of each pair at the same steering angle that the first pair of wheels had when they were at that location.
