摘要： PURPOSE:To contrive the stabilization of liq. surface in a tower by a method wherein a crude oil to liq. ratio obtained by the estimated yields resulting from a separation made of a newly-fed crude oil within the standard distillation range when a switching is performed between crude oil tanks is multiplied by a crude oil flow amt. to obtain a signal and, by this signal, the flow amt. of the liq. fed from a preflash tower is controlled. CONSTITUTION:When a considerable change takes place in the property of crude oil by a switching performed between crude oil feed tanks 1 and 2, a gas to liq. separation ratio in a preflash tower 8 is estimated from the estimated yields of LPG and light and heavy naphtha separated from the crude oil after the tank switching and a preset crude oil temp. at the outlet of a heating furnace 11. The estimated ratio in this tower 8 is multiplied by a crude oil feed flow amt. to obtain a feed forward signal and this signal is then added to an outlet signal of a liq. surface adjusting meter 34 acting to retain the liq. surface in the tower 8 in a predetermined position to obtain a signal, from which the crude oil flow amt. fed from the tower 8 to the heating furnace 11 is determined. As a result, this method can stabilize the liq. surface in the preflash tower as well as the operations of the heating furnace 11 and a crude oil distillation tower 12.

摘要： PURPOSE:To prevent the overload of a brine discharge pump at the start time of operation, in the titled water making apparatus provided with a final stage brine level regulator, by determining the set value of the aforementioned regulator by using the signal of a separate high temp. stage brine level detector. CONSTITUTION:In a multi-stage flash evaporation apparatus consisting of plural stages of evaporation chambers 4 each having a weir 15 vertically provided to the bottom plate thereof, a final stage brine level is detected by a detection meter 27 and made equal to a set value on the basis of the detection signal by a final stage brine level regulator 41. Herein, a brine level meter 50, a constant signal generator 51, an adder 52 and a level set value correction and operation apparatus 100 are additionally provided. The apparatus 100 gradually increases output (the input of the adder 52) corresponding to the reduction in the output of the first stage level meter 50 (capable of being substituted by second and third stage ones) at a start time and imparts the same to the adder 52. On the other hand, the generator 51 outputs the final stage level set value at the time of steady operation to apply the same to the adder 52. The adder 52 applies said output to the regulator 41 as the final stage brine level set value.

摘要： PURPOSE:To set lower pressure resistance at the downstream side than that of the upstream side of a gas pipeline and to reduce the cost, by providing cutoff valves at the middle of the pipeline to control the gas pressure. CONSTITUTION:The gas is transported from a supply base 4 to a receiving base 12 by means of pipelines 5, 8 and 11 along with cutoff valves 6 and 9. Pressure detection controllers 7 and 10 detect the pressure of the downstream side of the cutoff valve. Then the valves 6 and 9 are fully closed when the downstream pressure exceeds the level set individually and then fully opened when the downstream pressure is less than the set level, respectively. As a result, the pressure never exceeds the set level for the pipelines 8 and 11. Thus it is possible to set the pressure resistance of the pipeline lower at the downstream side than that of the upstream side. This process makes it possible to use a thin-walled pipeline material to reduce the cost of a gas pipeline.

摘要： PURPOSE:To eliminate complicated manual operation or the trouble by pump overload, by making it possible to change over the mode of a brine level regulator from an automatic mode to a fixed mode when the brine level of a high temp. part was lowered at the time of start operation. CONSTITUTION:Prior to the start of flash evaporation at a start time, the flow amount of supplied seawater is equal to a blow-down flow amount but, as flash evaporation is promoted, the blow-down flow amount becomes much by the action of a brine level regulator 25 or a regulation valve 19 and the brine level of a high temp. part is lowered. When the lowering in the brine level is detected by a brine level detector 30, the regulator 25 is held and fixed in the vicinity of the output value at that time and the brine level of a final stage is lowered before long and, at the point of time when said level reached the almost steady objective value prior to change-over, the brine level regulator 25 is returned to an automatic mode. By this method, the blow-down flow amount by a brine discharge pump 28 is prevented from becoming excessive and uniform flow is achieved.

摘要： PURPOSE:To enable to stably supply the steam produced at solar heat absorbers by a method wherein the difference between the pressure in a steam separator drum and the pressure in a heat accumulator is kept constant by means of a control valve and a circulating pump for a downcomer is driven when the percentage of void in an absorber and the temperature in a boiler section exceed the predetermined values. CONSTITUTION:When heat absorbing boiler surfaces 4 absorb heat by receiving the solar heat (a) concentrated by a concentrating type solar heat collector, the natural circulation (b) of water generates, resulting in causing to rise the pressure in an absorber. At the time, when the difference between the pressure in a steam separator drum 1 and the pressure in a heat accumulator 12 reaches the predetermined value, which enables to transport steam, a control valve 7 is brought into actuation in order to supply the steam (c) through the heat accumulator 12 to load. If the detected percentage of void in an evaporating tube 6 or the detected temperature at the upper part of the boiler surface shows the excess over the predetermined value, a controlling circulating pump 8 is driven, resulting in preventing the boiler section including the heat absorbing boiler surfaces 4 and the evaporating tube 6 from overheating.

摘要： PURPOSE:To easily enable corresponding to the interstage pressure difference in a wide range by providing a buffer, a controller for the amount of fresh water to be produced and various arithmetic units. CONSTITUTION:Seawater introduced from a cooling water pump 24 is passed through a distiller 8 and thereafter one part thereof is discharged outside and the remainder is passed through a branched water feed pipeline 39 and introduced into a brine reservoir 14n of a final-step evaporation chamber 4n. Brine is allowed to flow through a circulation route 26 and while it is passed through the distiller 7, vapor ascending from the lower part is condensed thereby. Then brine reaches the first-step evaporation chamber 4a and is subjected to flash evaporation. After generating vapor, the brine retained in the brine reservoir 14a is passed through an interstage brine flow passage 13 and introduced into a low-pressure evaporation chamber 4b and subjected to flash evaporation. The liquid surface 16n of brine incorporated in the brine reservoir 14n is detected by a detector 27 for the liquid surface of brine and compared with the preset value and excess brine is discharged through a control valve 29 outside.
