Patent GB-619574-A (GB)
Title: Improvements relating to the distillation of coal tar or mineral oils
IPC: C10C1/04
Filed: 1945-09-10
Abstract: <PICT:0619574/III/1> In a continuous distillation process in which coal tar or mineral oil is completely dehydrated and then passed through a pipe still, the hydrocarbon vapours being submitted to fractionation, some of the pitch produced in the process is mixed with the dehydrated oil by using a pump, the delivery of pitch from which is controlled by a pressure-responsive device in the downstream-pipe from the pipe still, so that there is turbulent flow through the pipe still.  The pitch is preferably mixed with the dehydrated oil in an injection chamber.  Coal tar is heated to a temperature between 150 DEG  and 180 DEG  C., preferably by a series of heat-exchangers which are heated by hot liquids and gases leaving the plant.  The preheated tar is introduced into a flash chamber where the steam and lightest oils are vaporized, and separated. The dehydrated tar flows into a reservoir from whence it is pumped to the tar chamber 113 of the injection chamber shown, which it enters through inlet 115.  The injection chamber has annular recesses 118, 119 and 120 to each of which steam is supplied.  Hot pitch is injected into the tar through tapering pipe 114; the arrangement being such that there is indirect heat exchange between the pitch and tar, and that when they actually mix, they have approximately the same temperature.  The mixture which leaves the injection chamber enters a pipe still where it is heated to a temperature of 330 DEG to 350 DEG  C.  It then flows through a pipe to the main flash chamber which has a connection leading to the fractionating column, and another to the pitch reservoir.  This pipe, leading the mixture from the pipe-still to the main flash chamber, contains an orifice plate which is connected to a valve in the steam-line of the pump which delivers pitch to the injection chamber; and by these means the amount of pitch delivered is controlled in accordance with the liquid flowing through the pipe-still.  The line which leads that pitch which is not pumped to the injection chamber, to the pitch bays, has a valve which is automatically controlled by a level controller actuated by the level of pitch in the pitch reservoir. Specification 608,301 is referred to.

Filed: 1945-05-25
Abstract: 594,833. Direct-acting engines ; combustionproduct plant. SULZER FRERES SOC. ANON. May 25, 1945, No. 13121. Convention date, June 3, 1944. [Classes 7 (i) and 7 (ii)] In a direct-acting engine intended particularly for generating products of combustion of . the type in which a precompressed gas from an external source is fed to at least one cylinder during normal operation and is further compressed therein by a free piston and in which a surface of a free piston is exposed to the precompressed gas when preparations are made for starting a pressure medium can be supplied through a regulating valve to a space partly bounded by a surface of the free piston which faces in a direction opposite to the exposed surface so that the loading on-the piston in one direction can be substantially balanced by a loading in the opposite direction. As shown, a precompresser 9 driven by a gas turbine 10 on electric motor 11 delivers compressed air to compresser cylinders 5 of a free piston gas generator. Pressure medium supply pipes 26, 27, 28 are provided communicating with the various engine spaces and these pipes include regulating valves 30-35 so that it is possible to substantially equalise the forces acting on the free pistons when preparations are made for starting. By means of the valves the engine spaces can be brought under the precompression pressure. In a modification, the invention is applied to an opposed piston free piston engine having at the right hand end a double-acting compressor supplied with air from a precompressor set and at the left hand end a doubleacting compressor which compresses air and supplies it to a consumption main. The compressor at 'the right hand end supplies compressed air for scavenging to the engine cylinder. In a further modification a free piston engine has a double-acting compressor supplied with precompressed air or gas, delivering to a consumption main while a second double-acting compressor draws in air at atmospheric pressure and supplies it to the engine cylinder for scavenging. It is stated that the regulating valves may be non-return valves with means for holding them open from time to time. The pressure medium supplied to the engine spaces may be the power gas. Some of the spaces may be supplied with the medium through reducing valves. One precompressor set may supply several free piston engines or a batch of free piston gas generators can be connected so that each supplies through a valve to a common delivery main.
