My workplace (refinery) gets n-butane and isobutane (for alkylation) from CCR, AVU. It gets olefins from FCC.
We currently do not have enough amount of iso and n-butane for 100% capacity utilization.
My queries are:
1) Will buying butane from outside and having 100% capacity utilization be a good option?
Alkylate is added to Motor spirit. Should I sell less MS or shouls I buy butane?
2) What exactly should I buy? Pure isobutane? a mixture of Iso and n-butane.
3) What companies trade iso and n-butane? How can I get there prices?
