Description

Kayser's Grand Refinery

The Most High-Tech Refinery Available

Combines Kayser's Compact Refinery and Kayser's Cracking Auto-Cracker into a highly advanced, versatile, auto-balancing refinery.
Compact, rectangular design for minimal space footprint.
Fully automatic balancing of Diesel, Naphtha, and Fuel Gas.
Highly efficient in terms of construction cost, workers, power, and maintenance.
Full Sour water stripping for maximum Ammonia, Fertilizer and Acid production and Water re-use.
Interconnected exhausts for easy connection to external exhaust filtration.
Readily accessible input/output storages for buffering, alerts, and easy mapping and connection of pipes and belts.
U3 UPDATE: Auto-Cracker updated to U3 recipes, added second F2 mixer, organic fertilizer boost, flames, burner. Simplified design to 2 stages (was 10).

Technical Features:

4 Crude Oil Distillation lanes with full capacity Sour Water stripping, balanced Acid and Fertilizer II production, Hydrogen Reformer, Dual "Boosted Fertilizer" Chem Plants that create their own Ammonia if there isn't enough. Possibility to convert excess Sulfur to Slag. See Kayser's Compact Refinery for full description. (https://hub.coigame.com/Blueprint/Detail/551)
2 Auto-balancing Heavy Oil -> Diesel <> Naphtha <> Fuel Gas crackers. See Kayser's Cracking Auto-Cracker for full description. (https://hub.coigame.com/Blueprint/Detail/560)
U3: Emergency overflow flames for Heavy Oil and Ammonia. Overflow Burner for Sulphur.

Stages:

Pausing or entering planning mode is recommended when placing blueprints.
U3 UPDATE: Because game now allows placing blueprint without requisite building technology, design has been simplified to 2 stages (but each stage must be applied multiple times to build new unlocked buildings).

Stage	Description	Technology Required	Upgrade Preparation	Upgrade Instructions	Other Notes
1	Starter / Pre-Naphtha Processing	Advanced Diesel, Transport Balancing (Pipes II recommended)	Clear land. Plan later expansion as per the pipe connectors.	Place the BP. Connect transports and unpause structures incrementally as required. Apply BP again after researching Boiler (Gas), Sour Water Stripper, and Fertilizers to add respective structures. Add recipes in Flare, Burner, Mixer, Chem Plant, and Smoke stack as needed.	Remove Sour Water tank when obsolete/empty. After Fertilizers + Chem Plants, remove overhead pipe from balancer TO Ammonia Buffer tank.
2	Post-Naphtha	Naphtha Processing, Biofuel, Fertilizers	Remove obstructing Light oil pipes.	Appy BP again after researching Reforming & Cracking, Hydrogen Production. Upgrade chemical plants and mixers to Mixer II as required.	Remove Light oil tank when obsolete/empty.

Input/Output

Maximum combined production of Diesel + Naphtha + Fuel Gas: around 250 (total depends somewhat on exact mix).
Given additional fuel and water, about 30 additional High Steam can be produced by the boilers and used for e.g. power, paper, or desalination.

Revision History:

Version	Comment
1	Initial Version
2	Minor bugfix
3	Removed dependency on Pipe III. Moved Sour water tank for simplicity. Fixed minor issues with supports being in the way on Stage 10 when having built incrementally.
4	Added Acid mixer. Re-routed some pipes to reduce cost. Added Hydrogen as an alternative Gas Boiler fuel.
5	Major overhaul for Update 3. Removed HO crackers (obsolete), updated Auto-cracker to include HO cracking. Added second F2 mixer, Organic Fertilizer, Flames, Burner.
6	Fixed issue with missing Hydrogen pipe. Downgraded to Chemical Plant I in Stage 2 due to Ammonia recipe not downgrading properly.

So its a very good design for the most part. In my use of it, I have only identified two potential problems. One is that the sulfur has to be manually managed. The fertilizer II does not use all of it, and it creates a flaw. I have to keep some sulfur in the storage because otherwise fertilizer I does not get used up, meaning ammonia backs up, meaning sour water backs up, and then the entire system jams. So i cannot take all of it out. However, I also cannot leave it all in because then the same thing happens as sulfur backs up. I have done some work to find a potential solution, and i believe i have found one. you just want two storages, linked to two different balancers. The first is priority to the internal system storage, the sulfur for making fertilizer II. The overflow goes on to another storage in priority for use in other projects, rubber, etc. If this overflows, there is a back-up burner attached. This would solve the problem. The problem is your build is such a maze of pipes (i honestly don't know how you did it) that I cannot add this fix to it in my world. The second problem is with heavy oil. The system does not currently prioritize turning heavy oil into the resource (diesel, naptha, fuel gas) to be used first. This results in me constantly having to watch it and flare it off when it gets too high because the system would rather turn crude into it, which would be fine, if it were not for the fact then the heavy oil backs up and jams the entire system. Other than these problems, very good build, i use it a lot.

I'm having an issue with the "auto balancing" of excess naptha, fuel, gas. The two cracking units seem to stop working as they aren't getting both of the inputs they need in any of the recipes at the same time. I've tried to work out why, but holy cow is it hard to follow those pipes. its constantly backing up in the diesel buffer and stalling the whole plant.

Kayser

Thanks for the comments, guys. Will keep them in mind if I update this, which I may do after U3 drops. See me on Discord for any other assistance. @Piraneous, you need to use at least 96 Diesel or else it will back up. Most people use more than that, especially if you use it for rubber or vehicle fuel. If you don’t, install an external cracking unit or use the diesel to Gold contract.

using this too and also saw some backing up in the fertilizer pipe. my solution was to install a flare fore excess in front of the 1st fertilizer plant.just had to shift the existing nh3 pipe above the fertilizer one and then you can attach it to the nh3 balancer which even is preconfiigured by priorizing the fertilizer plants, so you just flare the excess edit: actually it seems to have constant hickups... i assume one issue might be youre using a lot of long pipes with multiple products before separating. means hickup of one product can stall the full system.

Kayser

Update for U3 contains emergency overflow flame for Ammonia as well as Heavy Oil, and a burner for overflow Sulfur. There shouldn't be any long pipes passing multiple products left.
