Regulating Sector

Regulating Sector at City Gas Distribution System – Understanding

This is the forth post of city gas series. Check my previous post about how to calculate city gas flow rate, city gas network part 1, and understanding metering and regulating station. In this post, I want to share you about regulating sector. 

Before being distributed to house, gas pressure and gas flow from tapping point will be monitored in metering and regulation station (MRS). After leaving MRS, gas will be distributed via distribution pipeline which is usually MDPE pipe.

In my project we use 63 mm pipe or 90 mm pipe for distribution pipeline.

Gas distribution is usually grouped. Each group covers several houses, which can be as low as 900 houses to 2000 houses. In each group, we installed regulating sector.  (more…)

Understanding Metering and Regulating Stations and Its Part

This is the third post of city gas series. Please check the first post about how to calculate city gas requirement and the second post about city gas distribution network part 1

In previous post, I share you one important part of city gas distribution equipment which is Metering and Regulating Stations (MRS). For review, the function of MRS is to monitor flow rate of gas and to reduce gas pressure thus it meets requirement. Gas pressure is reduced from more than 16 bar to 5-15 bar in MRS. I checked in “City Gas Network Handbook” published by Indonesian Government, maximum pressure of city gas distribution system is 7 bar, although in reality, gas operating pressure is not that high.

City gas network

City Gas Distribution Network (Part 1)

This is second post of city gas network series. For the first post, please check “City Gas Flowrate Requirement”.

City gas distribution is one of Indonesia national priority program which purpose is to diversify energy, to reduce energy subsidiary, to provide clean and cheap energy, and as complementary program to convert cerosene into Liquified Petroleum Gas (LPG).

The total installed city gas until now is 56,888 house connection. It will be increased year by year. For example in 2013, the government planned to installed 16,000 connection. (more…)
