A brief discussion on the level control technology for high-efficiency oil-gas-water three-phase separators. Currently, crude oil extraction techniques involve injecting fluid underground simultaneously with oil extraction in order to maintain a constant pressure underground. It facilitates continuous mining. But this raises a problem: as the extraction process continues, the water content in the crude oil extracted later increases, which requires specialized equipment to separate oil from water during the extraction process. At the same time, since gaseous by-products are inevitably produced during the long formation process of crude oil underground, some amount of oil and gas will always be produced during its extraction. This also requires specialized equipment to separate oil and gas. The use of oil-gas-water three-phase separators fundamentally solves the problem of separating these two substances with different properties! The normal process is as follows: the oil-gas-water mixture enters the separator, where, under high pressure, gas-liquid separation occurs first, and the gas is discharged. In oil-water separation using the density difference between oil and water, the less dense oil enters the oil chamber! Thus achieving the goal of continuous separation! In the process of oil-gas-water three-phase separation, maintaining stable liquid level is the most important first step! Only when the liquid level is stable can the equipment operate properly, thereby ensuring the smooth progress of operations upstream! If the liquid level cannot be maintained stable, a \"caving in\" accident will occur, affecting production upstream! Regarding level control, the vast majority of oil-gas-water three-phase separators in use today still rely on float-type level regulators! Change the product to a purely mechanical version with no energy consumption! Moreover, it can be adjusted to equal percentages or proportions as required by the customer, offering wide applicability! Most importantly: this product controls the liquid level by regulating the outflow of liquid. In other words, as long as the inflow volume is below the specified requirement, no matter how the content of the inflow stream changes, this product will always be able to find the appropriate valve opening time in the shortest possible duration! Moreover, as the demands for this product on the market increase, some companies with R&D capabilities stand out and gain an advantage in competition! For example, Jiangsu Huai’an Huanyu Machinery Co., Ltd., in response to market demands, independently developed a special float level regulator for high-pressure oil-gas-water three-phase separators. Special float level regulator for anti-corrosion oil-gas-water three-phase separators.! After years of use, it has received positive reviews from users! And exported to Sudan and the Far East! With the continuous advancement of electronic technology, some combined stations now use automatic control methods to regulate liquid levels! However, from what the author knows, the performance is not very satisfactory; the main problem is instability! The normal mode of a control system is as follows: the sensor sends a signal to the processor, which then controls the actuator; after the actuator completes its action, it sends feedback information back to the processor. That completes one adjustment! There are two issues here: “1. In the process of transmitting an electrical signal until its execution is completed, there are three execution units, and if just one of these units fails, it will affect the entire system!” 2. For the final actuator, excessive frequent operation can easily cause damage! Therefore, the control system currently in use is not ideal!
