[CNG, LPG and biogas distribution](https://www.materialinsights.org/energy/e_cng_lpg/) (energy) and [Refining and reforming](https://www.materialinsights.org/energy/e_refining/) (energy): 2 relationships.

## How they are linked

### 1. Energy flow

*Physical flow · 4% of flow · Refining and reforming → CNG, LPG and biogas distribution*

Refineries produce LPG for cylinders.

- **4%** of Refining and reforming's energy goes this way

### 2. Price link: co-product

*Cost and price · Strong · Both ways*

Refineries produce LPG as a by-product of crude processing, so refinery runs add supply. The refinery products index correlates with propane at 0.51 for monthly and 0.76 for yearly moves, since oil markets set both.

- **0.51** monthly change correlation
- **0.76** 12-month change correlation
- **0.83** fitted elasticity
