C. The crude gas is withdrawn from the gasification reactor at a temperature of 1300.degree. to 1600.degree. C., quenched with a water spray to cool it until at a temperature of 700.degree. to 900.degree. C. and then further cooled by indirect heat transfer in a heat exchanger producing steam until at a temperature of from 220.degree. to 300.degree. C. The cooled crude gas is dedusted until a dust content of less than 20 mg/Nm.sup.3 of crude gas is reached and the dedusted gas is washed and desulfurized to form the product gas.

摘要： A circuit arrangement for determining the polarity and the magnitude of the load current in a reversible d-c controller includes a bridge circuit comprising two pairs of bridge arms connected to opposite terminals of the voltage supply bus. Each pair of bridge arms connected to the same side of the supply bus form a bypass circuit connected across the load. Two diagonally disposed bridge arms each contain a primary winding of a current transformer having two primary windings connected in opposite winding phase. Load current normally flows through either pair of diagonally disposed bridge arms, but during pauses in the load drive, circulates in one of the two bypass circuits. Electronic switches in each of the bridge arms are controlled so that the load current circulates in successive bypass periods in an alternating pattern in the two bypass circuits. When current flows in a bypass circuit, a phase sensitive voltage is induced in the single secondary of the current transformer. Signals from the electronic switches in one of the bypass circuits are fed via digital logic circuitry to a further electronic switch which causes an operational amplifier to invert pulses from that bypass circuit alone. A pulse train having a polarity corresponding to the polarity of the load current is thereby obtained. In a further embodiment, a sample-and-hold stage for determining the magnitude and polarity of the load current is provided.
摘要翻译： 用于确定可逆d-c控制器中的负载电流的极性和幅度的电路装置包括桥接电路，其包括连接到电压供应总线的相对端子的两对桥臂。 连接到电源总线同一侧的每对桥臂形成一个连接在负载上的旁路电路。 两个对角布置的桥臂各自包含电流互感器的初级绕组，其具有以相反绕组相连接的两个初级绕组。 负载电流通常流过任一对对角布置的桥臂，但是在负载驱动中的暂停期间，在两个旁路电路之一中循环。 控制每个桥臂中的电子开关，使得负载电流在两个旁路电路中以交替模式在连续的旁路周期中循环。 当电流在旁路电路中流动时，在电流互感器的单次级中感应出相敏电压。 来自旁路电路之一的电子开关的信号通过数字逻辑电路馈送到另一个电子开关，使得运算放大器单独地反转来自旁路电路的脉冲。 由此获得具有与负载电流的极性对应的极性的脉冲串。 在另一实施例中，提供了用于确定负载电流的大小和极性的采样和保持级。

摘要： A process for removing silicon compounds from aqueous NaCl brine includes, first, adjusting a weak brine to a pH value of less than 3 with hydrochloric acid. Iron(III) chloride or other trivalent iron ions are added to the acidified weak brine, the obtained weak brine is then continuously fed to a stirred dissolution vessel which contains undissolved salt in addition to brine. Fresh salt is charged batch-wise and intermittently to the dissolution vessel to produce strong brine. The obtained strong brine is fed to a stirred buffer vessel, the pH value in this buffer vessel being maintained at a level ranging from 5 to 8. A strong-brine flow is continuously withdrawn from the buffer vessel and filtered, and the filtrate containing the added iron and silicon is discharged. Also a system for carrying out this process is disclosed.

摘要： In the process for purifying an aqueous MDEA-solution the formate content of the MDEA-solution circulated in a main stream between the absorber and desorber of a hydrogen sulfide wash unit for gas produced by gasification of a carbonaceous material, e.g. coal, is measured. A partial stream of MDEA-solution is withdrawn from the main stream, passed over an ion exchange medium which removes some formate present to form a partially purified partial stream and subsequently the purified partial stream is returned to the main stream. The amount of the withdrawal from the main stream is controlled so that the formate content of the main stream is maintained between 10 and 30 g/l. Only from 0.5 to 0.08% by volume need be withdrawn from the main stream to form the partial stream. The ion exchange medium can be regenerated with a hydroxide-containing solution, which is subsequently fed to an ammonia separator column of a hydrogen sulfide wash apparatus.
