What should be considered in the design of unloading areas on the general layout?
Thread Content
I just started working at an engineering company; I have a background in construction, and for now I’ve been assigned to work on site planning. I’m the only one handling this task, with no one to turn to for advice. Now I need to design 6 unloading areas, using hoses instead of boom pumps, and I can’t find any guidelines regarding the dimensions required. I asked some seniors from other departments, who said that a pit should be created to collect any leaked liquid, but I still can’t find any relevant standards. I hope those who specialize in site planning can give me some guidance
A newbie in construction is really helpless! !
Hoses are generally used only for temporary loading and unloading, and are not suitable for long-term use in these purposes. As for the spacing requirements, those for hoses equipped with dip tubes can be referred to. Regarding the specific regulatory requirements and whether a liquid collection tank is necessary, the relevant standards should be consulted
Sorry, I just arrived and don’t quite understand the rules yet! I’m sorry! The boss said to use a hose, so there’s probably no way to change that. Are there any regulations regarding leaks during loading and unloading? It seems that I’ve only found regulations related to the liquid collection ponds within the tank area. Is it necessary to make the unloading area sloped? Thank you
Conventionally, the process engineering department is responsible for specifying the layout conditions within the loading and unloading area. The electrical, instrumentation, water supply and drainage, and structural engineering departments (and possibly the architectural department, depending on the division of tasks) are then involved. The landscape design department aggregates the feedback from all these departments, and determines the safe distances between this area and other facilities in accordance with relevant building codes and petrochemical industry standards. It is also necessary to verify the safety and fire protection distances within the loading and unloading area. Additionally, the landscape design department handles its own tasks, such as determining the roads that connect to the entire plant, the elevation of the ground surface, areas designated for vehicle turnaround within the loading and unloading area, the layout of the area based on the plant’s logistics needs, and the placement of weighing scales. The collection tank is usually handled by the water supply and drainage team, who calculate its volume and requirements; its location is determined through consultation with the overall layout plan. The things you mentioned are not something that the general layout department takes into account; of course, I’m referring to the division of responsibilities within the company where I work. .

The collection tank should be considered by the water supply and drainage specialists, as it needs to be integrated into the sewage system – should it flow by gravity into the main sewage pipe, or is it necessary to use submersible pumps or self-priming pumps to transfer the water there? These are all system-related issues; just setting up a collection tank isn’t enough – one also has to consider the direction in which the fluid will flow. The unloading area requires a site with a certain slope; it depends on whether gravity flow or pumping is used, but the material must be unloaded completely. When setting the slope, it is necessary to consider installing sewage ditches at the lower points to connect to the sewage system and integrate with the water supply and drainage services. Static grounding, vehicle barriers, crash pillars, and the like also need to be given careful consideration.
