Today’s topic is the design guidelines for tank truck loading terminals used for petroleum products. It is worth noting that liquefied petroleum gas and cryogenic liquids are exceptions. For clarity, we provide step-by-step guidelines. Step 1: Establish the road transportation of the product for the given design year. The following steps need to be determined: the peak annual production volume for each product and the frequency of peak times (number of trucks per hour) during those periods. Step two involves identifying the characteristics of the truck fleet as well as the local factors related to road transportation; the following sub-steps need to be determined: characteristics of the vehicles, capacity of the trucks, spacing between trucks, amount of product carried by each truck, whether loading and unloading take place at the top or bottom, total dimensions of the trucks (length, width, height), minimum turning radius, as well as local factors, preferences, regulations, and details regarding the type of terminal operations. Terminal daily working hours and daily operating time. Desired level of terminal automation. Guidelines or regulations for steam recovery. Filling of consecutive or simultaneous truck trailers. Rules (principles) for the transfer of measurement and regulation. Average/longest waiting time per truck during peak hours. End-user preferences or **rules regarding terminal operations. Step 3: Predict arrival patterns based on local experience to meet the needs of customers in the delivery area. Peak arrival cycle: trucks per hour and duration (for example, the morning queue can represent the highest arrival frequency in a relatively short period of time). Seasonal changes: For certain products such as automotive gasoline, heating oil, fuel oil, asphalt, etc., seasonal changes are significant. Step 4: Establish the design or basic case configuration. Group trucks are loaded by product. Calculate the average loading time for each product. Assume that loading should be stopped; unless otherwise advised, fill in the values in order. Calculate the filling time; allow for lower initial and final rise rates (see attachment). Establish a normal filling rate based on local conditions. 30 liters/second (500 gallons per minute): Truck capacity less than 15 cubic meters (4000 gallons). 50 liters/second (800 gallons): Truck capacity 15 cubic meters (4000 gallons) or more. Calculate the filling time for each compartment. (Total volume loaded – loading during slow start/recharge) / loading rate. ) (Assuming the start/filling rate is 10% of the normal filling rate) Total filling time = Filling time per car * Number of intervals.
