The condensation-adsorption Vapor Recovery Unit is recoery vapor for
the loading gantry and tankers . The condensation + adsorption process combination can generally condense vapour to -75℃ (multi-stage cooling) according to the medium properties. Alkanes above C3 are basically condensed and recovered, with a recovery rate of more than 90%. The remaining small amount of alkanes is sent to the adsorption system for adsorption treatment, and the qualified tail gas is discharged after adsorption; after desorption, a small amount of vapour returns to the system inlet for circulation. The VRU overall recovery rate can reach more than 97%. The Vapor Recovery Unit（VRU）setting of the refrigeration temperature is designed and formulated according to different working conditions.

To enhance packaging quality, strengthen packaging management, and prevent product loss or damage during transit resulting from packaging-related issues, this Export Packaging Specification has been specifically formulated.
This specification applies to the packaging of all products exported by this Company.
| Requirement | Responsible Dept. | |
| Before Packaging | Confirm that the product has been tested and is free of defects. Confirm that the product’s exterior is clean and free of stains, standing water, or similar issues. | Quality Dept. |
| Product Packaging | 1. Skid-mounted and Containerized Packaging: A three-layer packaging system—comprising inner, intermediate, and outer packaging—is required. The packaging must be securely fastened and stable, providing effective protection for the product. a. Individual instruments on the skid must be protected with bubble wrap and tightly bound with stretch film. b. The entire skid must be protected with bubble wrap and tightly bound with stretch film. . Containers equipped with racks must be securely fastened using strapping bands. d. Loose piping must be wrapped in protective fabric to prevent paint damage from impact, and then placed onto a dedicated packing rack. Legend 2. Individual Packaging A three-layer packaging system—comprising inner, intermediate, and outer packaging—is required. The packaging must be securely fastened and stable, providing effective protection for the product. Inner Packaging: Foam wrap must be used to fully enclose the items, ensuring that no direct collision or friction occurs between products or between the products and the carton. Each individual item must bear both Chinese and English labels to facilitate inventory verification by the customer. Intermediate Packaging: Packed in cartons. Outer Packaging: Wooden crate packaging. The materials used must consist of plywood crates (fumigation-free) reinforced with steel strips. Any remaining space inside the box must be filled with cushioning material. For heavier products, particular attention should be paid to packaging strength to prevent damage during transit. | Production Dept / Warehousing & Logistics Dept |
| packaging | 1. Steel strips / wide wooden slats to wrap the 8 legs. Note: Wooden slat width: mm; thickness: mm. 2. 6–8 reinforcement points inside the box. 3. For any face exceeding 2 CBM, cross-bar or I-beam steel reinforcement is required. Note: The spacing between cross-bars/I-beams must be less than or equal to mm. 4. All packaging must include forklift access points to facilitate loading and unloading. 5. Packaging must be designed based on the dimensions of the container; under no circumstances should it exceed the container’s length, width, or height. | Warehousing & Logistics Dept |
