Jhbj. Hoebink et al., ECONOMICS OF THE OXIDATIVE COUPLING OF METHANE AS AN ADD-ON UNIT FOR NAPHTHA CRACKING, Chemical engineering & technology, 18(1), 1995, pp. 12-16
The feasibility of methane coupling as an add-on unit to a naphtha cra
cker was studied. The existing cold box was used for separation of eth
ylene and unconverted methane, but arrangements were made for separati
on of the coupling by-products. The cracker's methane was used as a fe
edstock. The concept is technically and economically feasible at sprin
g 1992 prices, provided the catalyst meets the assumed 30% conversion
and 80% C2 selectivity.
