Calen Oil Refinery by trains

Original blueprint: https://coigame.com/Blueprint/350/Oil-Refinery

My version includes some staged features and improvements which I solved during my implementaions of Calen's original art.

Versions

1. Initial complete build
2. Staged version
3. Added Diesel to Gold and Gold to Oil cargo depots BP

Changes to original BP

Stage 1

Sour water dumpers moved to make space for 8 depots
Removed small diesel gen to separate BP (to be easily removed via the same BP) as part of upgrade to large gen)
Re-routed boiler exhaust for smooth upgrade to scrubber
Cargo depot fuel re-routed
One more balancer for crude oil to prioritise oil supply from train station.

Stage 2

Sulfur properly buffered
Added balancer for smooth upgrade with priority to Naphta

Separate add-on to reprocess ammonia to hydrogen

stage 9

Extra naphtha goes to diesel instead of smoke stack.
Optimised hydrogen flow to cracking units.

NOTE: Performance of that stage isn't sufficient to run all 6 distilling lines, so extra nahptaa still needs to be burned in flares or cracking units have to be boosted.
Cracking priority still set to heavy oil.

stage 12

Addon to reprocess CO² to Graphite

Train stations

Stage 1 - Separate BPs for ingress crude oil and egress diesel

Stage 2 - Egress stations for Rubber/Acid

Stage 5 - Egress water/brine

Stage 6/7 - Egress Salt/Chlorine

Stage 8 optional addons - Either egress or ingress Fuel Gas. Maps provide extra dirt which could be traded to Fuel Gas and it is better to reprocess it to hydrogen. In case of lack of fuel gas - it could be exported. Just place egress station over ingress to change direction.

Stage 9 - Hydrogen egress. Calen's Oil Refinery is a good place to begin migration to hydrogen vehicles, but late in the game its performance became insufficient. Try this solution https://coigame.com/Blueprint/2502/Fuel-gas-to-hydrogen-by-trains

Stage 10 - Egress plastic

Stage 11 - Stations for slag & limestone for exhaust filtration

Stage 12 - Egress Graphite, ingress Coal for it
Add-on to import CO² to be reprocessed to graphite. My BPs of train stations for Unified foundry, Concrete and Paper are exporting CO²

Add-on to balance Sulfur with automatic import/export when needed.

Add-on egress Gold (requires diesel-to-gold contract)
Cargo depots for 6/8 slots - BPs work in progress...
