590814 V. Description of the invention (1)-:-[Technical field to which the invention belongs] The present invention relates to a method for removing and treating a Shi Pei reaction tank. It has a built-in catalyst for refining crude oil required for crude oil. In the reaction tank, after the catalyst is cracked for a period of time, the safety / monthly removal treatment in the reaction tank is required. The method is to prevent the long-term segmented manpower from entering the manhole. Work-Shi Yu excavated for a fixed time to eliminate the dangerous work of the waste catalyst 'also avoids the accidental explosion caused by the rapid reaction caused by the temperature rise of the coke layer of the S catalyst because it is not combined with oxygen during work, and due to improper removal The compensation for the damage to the wall surface of the reaction tank is very high. Therefore, the implementation of extremely and safe processing steps can not only directly from the bottom of the reaction tank but the hole will be removed; the waste catalyst can be easily removed, and the inner wall can be quickly removed by using a high-pressure water gun. The solid, solid catalyst coking layer is cleared and discharged until it is on the bottom cushion layer, which can be safely entered manually and then removed by high-pressure water. It has a forced cooling effect in Trent processing, and greatly reduces Construction of the real benefits and costs. [Previous technology] Regarding the early stage of the development of the petrochemical industry to a period of high growth, it experienced technological innovations such as upgrading production technology, developing new products, and converting raw materials. The scale of machinery and equipment has increased, and the production scale has increased. Air pollution, water pollution, stench, noise and other environmental hazards. The petrochemical industry (hereinafter referred to as the petrochemical plant) has also constantly experienced explosions and other fire accidents, affecting society to attach importance to the safety of the petrochemical industry and require improvement; Historically, the manufacturing process of any chemical product has to evolve through various steps. Therefore, it is inevitable that terrible chemical catastrophes will occur, resulting in personal injury, property damage, and equipment damage.

In recent years, occupational safety accidents caused by fires and flammable gas explosions in Taiwan ’s petrochemical plants have accounted for 7 5 · 6 96, so preventive regulations The occurrence of explosion disasters is an important issue for disaster prevention today. Please refer to the first and second figures. The z-like petrochemical plant uses several channels of reaction tanks (1) for refining crude oil for pre-requirement. Each reaction tank (1) is filled with different components. "Catalyst" causes the external crude oil to be injected from the manhole (1 1) of the first reaction tank (1) as the first catalyst cracking reaction, and then connected to the outlet pipeline through the reaction tank (1). (1 2) The first refined oil product is introduced into the second reaction tank (1) The second catalyst cracking reaction is being performed, and the third reaction tank (1) is continuously stored until the first The four reaction tanks (1) wait for the predetermined catalyst cracking reaction, and finally refine to form the required oil resources. In the reaction tanks (1) between these channels, after long-term use of the catalyst, the heavy metals contained in the feed oil will adhere to the catalyst surface, resulting in a decrease in catalyst activity and a reduction in the required oil production and The increase in gas and carbon deposits also caused the internal catalyst to naturally form near the tens of centimeters thick flakes from the solidification and solidification of granules. The entire reaction tank (... inside: that is. Therefore, in order to maintain the activity of the catalyst in the reaction tank (丄) and reach the == = medium, the reaction tank (1) = must be cleaned for a period of time.)

To pull in during alternate use Area, in response to the casualties can only make it easier and more troublesome 6. In addition to handling the accurate control of the staff, the danger is coming, resulting in accidental operations or improperly compensated accidental injuries cleared out during the internal temperature transportation process It also aggravates the length of the staff when they enter the work, and the coking layer of the coke is peeled away inward, so that the coke must be held up to seventeen from the bottom, so the staff ’s psychological negligence will cause harm. The resulting coking layer is very large, especially when it is loaded into the reaction tank during the process of being transported by sunlight. The large-scale tank that is naturally peeled off and dropped in the middle layer must be unloaded at a slow speed. And a reaction tank needs to be cleared. It has to work continuously for several months, so waiting for all four reaction tanks to be completed will consume the entire year of operation time. It is not economical and the reaction tank of about twenty-four meters often faces heavy coking. The layer will be accompanied by the personnel often have to undergo training and promote mental overload, once it will be caused by the unknown consequences of the staff. Easily affected by the outside air and When the shadow of temperature enters the space bag, a considerable volume of bag fires and the heat storage generates the risk of high temperature and spontaneous combustion. The danger of internal shattering and vacuum suction is increased, which will cause slower work separation and easier production. It will cause high-risk coking layer. It is easy for the staff to soften and remove again. Therefore, it is extremely difficult for the staff to enter the reaction tank to perform the shattering work. Because they cannot control their strength, Once hit by the wall of the reaction tank

Person 1 said the princess: i = as shown in the first and fifth figures * One ... " Residual liquid place U! 6 3 4 3 "Residual liquid treatment system in the tank, tank", method for draining and recovering residual liquid in the tank, and tank In the main scope of the invention patent = the main scope of the invention patent case, the device is described as :: the suction tank and the pumping chestnut, so that the pressure in the suction tank is reduced: the residual liquid in the oil tank is discharged, and the sucked residual liquid is removed by The second mechanism includes an oil-water separation device, condensate j, and a pressure feed pump, and sends the oil from the residual liquid of the second mechanism to the oil storage: the U oil-water separation device and the agitation scum tank are treated. The spraying device of the pump is used to spray the pure liquid. 1 to slot

Because the device is designed to remove the residual liquid in the accumulation "oil tank", the liquid produced by dissolving the residual liquid sludge is discharged together with the jet liquid, so the object it is applied to is formed by the inside of the aforementioned petroleum reaction tank.

Page 10 590814 V. Explanation of the invention The method of media coking layer is that the oil film of the residual liquid is attached to the coke tank of twenty-four, which is compared with the high contact weight of several people (7). Because of this device, it stays in the oil and stays in the wall. Meters, and the straight layer can only continue to work traditionally up to a few medium solid objects without clearing, thousands of mouths, completely different ways to ignore the oil tank's proportion in the tank, of course, but the aforementioned. The petroleum reaction diameter is in the order of ten The front line of the left side of the ruler was almost manually cleared for an anti-month, and the danger of the internal cause can be moved and can not be moved, and the removal of the techniques and fluids applied by the two is = when less, such as A thin layer is aimed at a behemoth that is adjusted to seventeen right, and the state of 111 is filled in the reaction tank. The coke layer obtained is spontaneous combustion. Especially the overall volume cannot be made by automated procedures. It can only absorb when the waste effect and explosion are different due to the different reaction tanks. This category is actually clear about the small size of the accessory I used to create small hard catalysts. The improvement in the processing capacity of the row of clearing is that the invention and the clearing of the disclosed work cannot be hardened and lifted. The method of adjusting the recovery of the tank is special, so the theory is that people have learned experience. The purpose is to clear the oil tank in the liquid state and remove hard pieces. The suction method used is used to suck large hard pieces to contact the coking hard body. Whether the suction tube is rubbed or not can easily cause the waste catalyst to form oxygen and accelerate friction. It will also easily cause the residual liquid treatment system in the fire and the residual in the tank. "Liquid treatment method and cleaning method in the tank" and "Petroleum" are different. The objects to be removed are: the method of solution is even more unique and cannot be studied in detail. Here, we adhere to the characteristics of petroleum reaction tanks and their conventional methods for many years.

590814, Invention Description (8) The deficiency of the method shall be researched and improved to provide an innovative method of removal and treatment, and all the missing persons who are used to improve the month shall be improved. [Summary of the Invention] The present invention is directed to a method of reducing oil production for a period of time to prevent internal production for a certain period of time. The coking layer is caused by industrial reactions to cause damage to the tank wall surface. Water scavenging is less during the construction period and does not spontaneously ignite or explode during the operation provided by the high-pressure water scavenging of the present invention. The invention 'ensures that the catalyst is mainly to provide a small amount of fluid contact between crude oil refineries, so it is necessary to stop During the construction excavation, the high compensation of the explosion accident is not so high. The pressure water gun under the reaction tank quickly reaches the bottom of the pad, and the substantial removal of the cost of the service is followed by the strong removal of the water source and the danger of the cold catalyst temperature. Because the temperature of the high-pressure water will not be a kind of petroleum that requires oil and the internal media is cracked, it is caused by the long-term separation of the oxygen combination of the spent catalyst in the reaction tank, and because it is not, the unloading at the mining end will The inner wall has a strong benefit on the solid ball layer. The method cooperates with the role of the original decomposition tank to raise it. Of course, the advancement of the construction is directly and strongly protected. During the construction process, the tank should be cleared and the catalyst should be cleaned. When the temperature rises, using a very hard part of the catalyst with a light and hard contact can safely cool the coking layer of the catalyst due to the cooling effect. It can ensure that there is no safety due to high performance. Remove the ascending south in the decomposition tank, and the processing method and reaction tank are lowered and required to be removed. The manhole enters it. It also avoids the catalyst to cause a sharp reaction which causes the reaction to be easily taken out. Then, after the large injection reduction, the water produced by the high pressure water as the cleaning treatment temperature is sprayed under high pressure.

The water itself determines the temperature of the water grabbing, so it will hardly be half the construction period during construction, which can save considerable cleaning. The high pressure water grabbing is used to remove the part removed from the coking layer. To identify the danger of collapse, for the safety of the construction, and the sprinkled catalyst knots are sprinkled with water, the safety of the required transportation time can be maintained. [Embodiment] The cooling can be used to ensure the temperature of the construction is stable and the performance can be performed. The whole can quickly recover the progress of the reaction tank and reduce the cost. The method of removing the coking layer can be quickly divided into small pieces, which makes it difficult to produce large staff. It also guarantees that the remaining pieces of the coking layer will no longer need humidity and low temperature during transportation, which can effectively improve the load. The technical means, inventive features, purpose and effect of the invention are easy to understand. The detailed description of the drawings and numbers are as follows: f First, please refer to the sixth to tenth drawings. The present invention is designed and applied in built-in.

(2); 3 · Then use high pressure water to grab (3) and continue to wash and remove the coking layer (2) in the wall with high pressure until the coking layer (2) is completely removed, and the waste catalyst removed at this time It is naturally cooled by the water medium and maintains a considerable humidity; 4 · The artificial hole and the high-pressure water (3) are used to reach the reaction tank (1) from the bottom unloading hole (1 3), and the drop at the bottom end The coking debris and cushion layer (1 4) should be removed. 5. Then start with a high-pressure water gun (3). Enter the reaction tank (1) and wash it under high pressure from the top to the bottom, and then leak it out through the bottom unloading hole (1 3). 6 · Finally, the entire wall surface of the reaction tank (1) that has completed the waste catalyst removal treatment is cleaned with pure water. In addition, the present invention is to emphasize that the technical scope of the subject is intended to be solved. The present invention is directed to the use of a reaction tank (1) filled with a catalyst for refining crude oil (petroleum) required oil products, because it belongs to The volume is extremely large and the overall weight is nearly several thousand tons, and the built-in catalyst is also granular. After the catalyst is cracked with crude oil [petroleum], there will be 0 crude oil [petroleum] on the catalyst surface. Organic solvents and heavy metals are attached, so the catalyst will gradually form a coking layer (2) towards the wall of the reaction tank (1) and facing inward after using for a period of time, so the activity of the coking layer (2) is reduced to With continuous thickness accumulation, solid-state hardness naturally forms.
