Abstract

The invention relates to the technical field of LNG gasifying stations, in particular to a modular and standardized small LNG gasifying station and a design method thereof. The design method includes the steps that 1, a gasifying station is designed, the volume of each LNG storage tank is 20 m<3>, the gasifying capacity is 800 m<3> / h, LNG gasifying process flow is designed, and the gasifying station is divided into four modules for design according to the LNG gasifying process flow, and the four modules are the control system module, the LNG storage tank prizing module, the unloading gasifying pressure regulating metering prizing module and the connecting pipeline module; 2, the LNG storage tank prizing module is designed according to the LNG gasifying process flow; 3, the unloading gasifying pressure regulating metering prizing module is designed according to the LNG gasifying process flow; 4, the connecting pipeline module is designed according to the LNG gasifying process flow; 5, the control system module is designed according to the LNG gasifying process flow; 6, all the modules are integrally installed, wherein the plane layout of the LNG storage tank prizing module and the unloading gasifying pressure regulating metering prizing module are in an L shape, and design is completed.

Description

technical field [0001] The invention relates to the technical field of LNG gasification stations, in particular to a modularized and standardized small-scale LNG gasification station and a design method thereof. Background technique [0002] In real life, LNG gasification stations generally have two purposes: 1. In areas where pipeline gas transmission cannot reach, LNG gasification stations are often used as transitional gas source supply stations; 2. As emergency services in pipeline gas supply areas Used by peak shaving stations. [0003] The main work content of the LNG gasification station is to receive LNG into the LNG storage tank for storage, and then transport it to the municipal gas supply network after gasification, pressure regulation, metering, and odorization. , [0004] The design of a conventional LNG gasification station mainly includes general engineering structure design, gasification process design, gasification station control system design, building s...
