Funcionamiento del patín de dosificación y recirculación: Operation of the dosing and recirculation skate:
El patín de dosificación (100) es un equipo que tiene operación por lotes (discontinua), se carga una cierta cantidad de elementos geométricos en el cuerpo de dosificador (101 ) , se procede a llenar del hidrocarburo transportado y alinear con el ducto principal. Cuando su carga acaba, el dosificador se debe aislar del ducto por medio de la válvula de bloqueo principal (103) para ser drenado y retirar los posibles elementos remanentes. Luego el ciclo se reinicia volviendo a cargar al dosificador (101 ) una cantidad adicional de elementos geométricos. Para tal fin cuenta con tapas de apertura rápida para carga (108) y retiro (1 13). Esta operación se repite cuantas veces sea necesario de acuerdo con el requerimiento de concentración elementos geométricos a lo largo del ducto. The metering skid (100) is an equipment that has batch operation (discontinuous), a certain quantity of geometric elements is loaded in the metering body (101), the transported hydrocarbon is filled and aligned with the main duct. When its charge ends, the dispenser must be isolated from the duct by means of the main blocking valve (103) to be drained and remove any remaining elements. The cycle is then restarted by reloading the dispenser (101) with an additional quantity of geometric elements. For this purpose, it has quick-open lids for loading (108) and removal (1 13). This operation is repeated as many times as necessary according to the requirement of concentration of geometric elements along the pipeline.
El llenado del dosificador se realiza con el fluido transportado por la línea principal y para llenarlo se puede hacer directamente del ducto (alta presión) con la misma presión de operación utilizando la facilidad (102) y (1 19) o con el sistema de recirculación (150), utilizando la facilidad de llenado a baja presión (1 12). Esto último actúa como sistema de drenaje cerrado evitando degradación innecesaria de producto durante la operación, al permitir reinyectarlo al dosificador y por consiguiente a la línea principal. The filling of the dispenser is carried out with the fluid transported by the main line and to fill it it can be done directly from the duct (high pressure) with the same operating pressure using facility (102) and (1 19) or with the recirculation system (150), using the low pressure filling facility (1 12). The latter acts as a closed drainage system, avoiding unnecessary product degradation during operation, by allowing it to be re-injected into the dispenser and therefore into the main line.
El sistema de recirculación está diseñado con una configuración de bombas en paralelo 1 +1 (una de ellas operando y otra en modo stand by) con descarga a presión baja incluyendo protecciones por presión y flujo en succión y descarga. The recirculation system is designed with a 1 +1 parallel pump configuration (one of them operating and the other in standby mode) with low pressure discharge including pressure and flow protections in suction and discharge.
El tanque empleado para depósito del fluido recirculado está dotado de instrumentación para supervisar el nivel permitiendo realizar interbloqueos entre él y las bombas. El equipo dosificador incluye una caja de aguas aceitosas (preferiblemente conectada al sistema de drenaje abierto de la planta) que puede contener su volumen líquido en caso de requerirse. Además, el dosificador (101 ) debe ser diseñado para permitir su conexión al sistema de drenaje cerrado de la planta en caso de requerirse. En el diseño de tuberías de drenaje del dosificador se debe garantizar que la caída de presión sea tan baja que permita drenar de manera rápida haciendo más cortas las interrupciones de su operación. Por el contrario, para las líneas de carga y venteo es ventajoso llevar a cabo un diseño que permita estrangulación controlada para llevar la presión a un valor más bajo y seguro. The tank used to deposit the recirculated fluid is equipped with instrumentation to monitor the level, allowing interlocks between it and the pumps. The dosing equipment includes an oily water box (preferably connected to the plant's open drainage system) that can contain its liquid volume if required. In addition, the doser (101) must be designed to allow its connection to the closed drainage system of the plant if required. In the design of the metering drainage pipes, it must be ensured that the pressure drop is so low that it allows draining quickly, making interruptions in its operation shorter. On the contrary, for charging and venting lines it is advantageous to carry out a design that allows controlled throttling to bring the pressure to a lower and safer value.
Funcionamiento del patín de recolección y recirculación: Operation of the collection and recirculation skid:
El proceso de recibo de los elementos geométricos es un proceso continuo que requiere la extracción periódica y eventual de estos elementos de las unidades colectoras (201 ), a fin de evitar el taponamiento de estos equipos, lo cual puede generar presurización al sistema de transporte y reducciones en el flujo operacional. La extracción periódica de los elementos geométricos se realiza de acuerdo con los tiempos calculados de llenado de estas unidades, los cuales dependen de la dosificación de elementos en el sistema, la capacidad volumétrica y las restricciones operativas que limitan el proceso de dosificación. The process of receipt of the geometric elements is a continuous process that requires the periodic and eventual extraction of these elements from the collecting units (201), in order to avoid plugging of these equipment, which can generate pressurization of the transport system and reductions in operational flow. The periodic extraction of the geometric elements is carried out according to the calculated filling times of these units, which depend on the dosage of elements in the system, the volumetric capacity and the operating restrictions that limit the dosing process.
Adicionalmente, se realiza el retiro de los elementos geométricos cuando el diferencial de del cuerpo del colector (201 ) lo indique. Es importante tener en cuenta que, dado el carácter continuo de la operación de recibo, se requiere, de por lo menos, un colector (201 ) en espera“stand by” con el fin de no interrumpir la operación y poder realizar el proceso de extracción. Additionally, the geometric elements are removed when the differential of the collector body (201) indicates it. It is important to bear in mind that, given the continuous nature of the receipt operation, at least one collector (201) is required to be “stand by” in order not to interrupt the operation and to be able to carry out the extraction.
Cada uno de los patines de recibo, está compuesto por colectores conectados en paralelo, el número de colectores puede ser de uno o más. Este arreglo permite que, si uno de ellos se encuentra en mantenimiento o se hace el retiro de los elementos geométricos de él, por lo menos otro pueda continuar en operación. Una vez se cumpla el tiempo de recepción de los colectores (201 ), limitado por su capacidad o si se presenta alguna eventualidad, se debe realizar la extracción de los elementos geométricos. El colector (201 ) desocupado se deja en espera, es decir, cargado, pero no alineado, con el propósito que pueda entrar en operación tan pronto sea necesario. Each of the receipt skates is made up of collectors connected in parallel, the number of collectors can be one or more. This arrangement allows that, if one of them is in maintenance or the geometric elements are removed from it, at least one other can continue in operation. Once the reception time of the collectors (201) is reached, limited by their capacity or if any eventuality arises, the geometric elements must be removed. The unoccupied collector 201 is left on hold, that is, loaded, but not aligned, so that it can go into operation as soon as necessary.
Para su monitoreo, el patín de recirculación tiene instrumentación que registra la presión tanto del ducto principal como del cuerpo, así como de la presión diferencial de su cuerpo cargado. Esta última variable es monitoreada constantemente para evitar bloqueos y posibles sobrepresiones o pérdidas de succión en el sistema. La mayoría de las operaciones de apertura/cierre que se realizan en el colector son manuales, excepto la manipulación de las válvulas de bloqueo a la línea principal, las cuales por su tamaño están dotadas de actuador eléctrico. For its monitoring, the recirculation skate has instrumentation that records the pressure of both the main duct and the body, as well as the differential pressure of its loaded body. This last variable is constantly monitored to avoid blockages and possible suction overpressure or loss in the system. Most of the opening / closing operations carried out on the collector are manual, except for the manipulation of the blocking valves to the main line, which due to their size are equipped with an electric actuator.
