Operation Procedure for Low-Temperature Natural Gas Storage Vessel

1.1 Introduction to Station Pressure Regulation Process

Anpartial process flow diagram for the pressure regulating area is attached, with the equipment requiring operation numbered in the process flow diagram.

1.2 Pre-Pressure Regulation Preparation

1.2.1 Tool Preparation

Explosion-proof wrench, two pairs of gloves, and two sets of protective gear.

1.2.2 Work Preparation

Wear personal protective equipment, including antistatic clothing, static-free shoes, and safety helmets, etc.

(2) Ensure that devices prone to static electricity, such as cell phones and computers, are placed in a safe area. Check if the surrounding environment is safe and meets the operational requirements.

(3) Before entering, touch the static discharge equipment with both hands to release static electricity.

(4) Ensure that all pressure-regulating tools, such as explosion-proof wrenches, are carried.

(5) Inspect the tank's pressure gauge, level gauge, thermometer, combustible gas detector, and safety valve to ensure they are functioning normally.

(6) Inspect that the pipeline valves, pressure gauges, and safety valves are in normal working condition.

(7) Prepare all explosion-proof tools
