I haven't thought of any alternative recipes for that yet. I have been thinking of just adding a alt recipe that is more efficient but takes ammonia though. If you have any recipe suggestions feel free to share :D
Sure. I ended up just making one. I did an ammonia one funnily enough. I made it take carbon, ammonia, and heavy oil. I made it so it is made in the Cryogenic plant. I'm debating changing it from ammonia to ammoniacal solution for ease of use.
