In modern petrochemical terminals and bulk liquid storage facilities, the loading and unloading of hazardous liquids (like refined fuels, chemicals, and liquefied gases) is the most critical operational phase. Traditional, manually assembled loading racks are notorious for inefficiencies, high onsite construction costs, and—most importantly—significant safety and environmental risks.

To solve these challenges, Zhengzhou Yingjia Petroleum Engineering Technology Co., Ltd. has developed a state-of-the-art Automated Skid-Mounted Loading System (also known as a Bottom Loading Skid). Designed for precision and safety, this "plug-and-play" solution is transforming how tank terminals operate worldwide.

What is a Skid-Mounted Loading System?

A skid-mounted loading system is a highly integrated, modular unit that consolidates all necessary mechanical and electrical components for fluid transfer onto a single steel frame (the skid).

Instead of welding pipes, installing meters, and wiring electronics onsite, the entire system is engineered, assembled, and fully tested in Zhengzhou Yingjia’s factory. Once delivered to your terminal, it simply requires connecting the inlet/outlet flanges and power supply—reducing onsite installation time by up to 70%.

Core Components of the Yingjia Loading Skid

Our systems are engineered for Custody Transfer accuracy and HSE (Health, Safety, and Environment) compliance. A standard automated skid includes:

• Explosion-Proof Batch Controller: The "brain" of the skid. It interfaces with operators, controls the valves and pumps, and communicates with the Terminal Automation System (TAS).

• High-Accuracy Flow Meters: Depending on the fluid, we integrate premium Coriolis Mass Flow Meters or Positive Displacement (PD) meters to ensure exact custody transfer measurement.

• Digital Control Valves (Electro-Hydraulic): Crucial for preventing "water hammer" (hydraulic shock) in pipelines. The valve executes a multi-stage opening and closing profile (slow start -> fast flow -> slow stop) commanded by the batch controller.

• Safety Interlocks: Equipped with Static Grounding/Earthing monitors and Overfill Protection sensors.

• API Bottom Loading Arms: API-compliant loading arms with dry-break couplers for vapor recovery and leak-free operations.

Why Global Terminals Choose Zhengzhou Yingjia

At Zhengzhou Yingjia Petroleum Engineering Technology Co., Ltd., we understand that international EPC contractors and terminal operators care about reliability, compliance, and seamless integration. Here is how our automated control solution delivers:

1. Inherent Safety (Zero-Tolerance Interlocks)

Safety is non-negotiable when handling highly flammable or toxic media. Our system employs strict logic:

• No Grounding, No Loading: The pump and valve will not activate unless a safe static grounding connection (< 55Ω) is verified.

• Spill Prevention: If the high-level optic sensor in the truck compartment detects liquid, the system triggers an emergency shutdown within milliseconds.

2. High-Precision Custody Transfer (VCF Compensation)

To eliminate discrepancies caused by thermal expansion, our batch controllers feature built-in Volume Correction Factor (VCF) algorithms. By continuously monitoring the fluid's temperature and pressure, the system dynamically converts the gross volume to standard net volume (e.g., at 15°C or 20°C) in real-time, ensuring zero billing disputes.

3. Seamless SCADA/ERP Integration

Data silos belong in the past. The Yingjia automation control architecture supports standard industrial protocols (Modbus RTU/TCP, Ethernet). It integrates flawlessly with your existing SCADA or ERP systems, enabling automated order dispatching (via RFID cards or QR codes), real-time flow monitoring, and instant digital reporting.

4. Customization for Harsh Environments

Whether you are loading highly corrosive acids, highly viscous crude oil, or cryogenic LNG/Liquid Ammonia, we customize the metallurgy (e.g., 316L Stainless Steel) and instrumentation (ATEX/IECEx certified) to meet your specific site conditions.
