Gas distribution plants (GRP) are a complex of process equipment and devices designed to reduce the inlet gas pressure to a predetermined level and maintain it constant at the outlet regardless of gas consumption.
Depending on the equipment location, the gas distribution plants are divided into several types:
cabinet-type gas distribution plant (GRPSh): the equipment is placed in a cabinet made of non-flammable materials;
gas distribution unit (GRU): the equipment is mounted on a frame and placed in the room in which the gas-consuming unit is located or in a room connected to it by an open doorway;
modular gas distribution plant (PGB): the equipment is installed in one or more container-type buildings;
stationary gas distribution plant (GRP): the equipment is placed in specially designated buildings, rooms, or outdoor areas.
The fundamental difference of GRP from GRPSh, GRU, and PGB is that GRP (unlike the latter) is not a typical factory-ready product.
Main parts of GRP
The following main units are part of GRP:
- gas purification unit,
- gas pressure reduction unit,
- gas flow measurement unit.
GRP Bunter are designed for inlet pressure of up to 1.2 MPa and outlet pressure from 1 kPa to 600 kPa.
GRP is equipped with a minimum amount of automation equipment in accordance with the requirements (usually with a set of local indicating devices).
Bunter Group designs and manufactures all types of industrial gas distribution plants.
