Zusammenfassung:	A heater coil for heating a feedstock comprises an inlet manifold and an outlet manifold having longitudinal extensions that are parallel. A plurality of process tubes are suspended from and in fluid communication with the inlet manifold and the outlet manifold. Each process tube comprises an inlet leg coupled to the inlet manifold, an outlet leg coupled to the outlet manifold, and a U-shaped portion disposed between the inlet leg and the outlet leg for passage of the feedstock therethrough. The inlet manifold and the outlet manifold are elevated with respect to the plurality of process tubes. Each of the plurality of process tubes is aligned such that a width of the plurality of process tubes extends along a direction that is not perpendicular to the longitudinal extensions of the inlet and outlet manifolds.
