Chemical/ Liquefied hydrocarbons Metering and Loading Skid
Mainly used for loading and unloading various acids, alkalis, liquefied hydrocarbons and other room temperature medium. Due to different media properties, types of tanker and types of couplers, the technological principles and structural forms of chemical/Liquefied hydrocarbons loading and metering skids are also diverse.
Technical Features
Technical Features
For the top loading and metering skid, we generally design to place the process pipelines, instrument valves and electrical equipment on the ground for easy maintenance. Placing the loading arm, batch controller and foldable ladder on upper floor to facilitate loading and unloading operations.
The design of skid meets project specifications required by EPC and customer, and implements local standards and regulations. The skid is designed to meet SIS, HAZOP, and the electrical system is designed to meet ATEX or IEC and other explosion-proof requirements according to customer requirements.
The platform is highly integrated by upper and lower layers, saving time of on-site installation and commissioning. Only some flanges and cables need to be connected when skid is arrived at site, the installation and commissioning are simple.
Materials are base on customer requirements and media characteristics.
For the viscous medium which needs to keep at a certain temperature, heat tracing and thermal insulation layer are recommended. The heat tracing is optional with electric heating and steam heating.
For media with high airtightness requirements, Dry Coupler, API Coupler, ACME coupler, KJB coupler, etc., can be used on tanker, which can reduce the possibility of operator directly contacting with fluid and improve safety level of operations.
A level switch can be equipped on the loading arm to detect whether the tanker is full.
Equipped with electrostatic grounding controller to monitor the grounding status of tanker in real time.
Loading and unloading process and the standby state are automatically monitored. The audio and visual alarm and interlocking functions can be activated by abnormal signals detecting from temperature, pressure, flow, valve status, electrostatic grounding, and position switch.
Can be connected with DCS and SIS systems, and monitored by the main control system of factory.
Product Parameters
Product Parameters
| Liquid Pipeline | The loading line is used to load the medium from the storage tank to tanker. The pipeline is generally equipped with a pump, an emergency shut-off valve, a degassing filter, a flow meter, a flow control valve, a safety valve, and pressure and temperature instruments to achieve quantitative loading. |
|---|---|
| Vapor Return Pipeline | The vapor return pipeline is used to recover medium vapor in tanker, prevent it from leaking and polluting the atmosphere, and reduce pressure in the tanker. The pipeline is generally equipped with a shut-off valve, flame arrester and check valve. |
| Drain Pipeline | Used to drain residual liquid in the pipeline for convenient maintenance. |
| Nitrogen Purge Line | Generally used to purge the pipeline after loading, preventing residual medium in the pipeline from polluting atmosphere. |
| Instrument Air Line | Provides purified compressed air for the pneumatic actuator. Design pressure is 1.0 MPa. |
| Vent Pipeline | Exhaust vapor in the whole loading skid is collected. The collected exhaust gas can be directly vented and burned or reliquefied after treatment. |
