A vaporizer is provided for vaporizing liquid in a fluid stream. The vaporizer includes at least two heat exchangers serially arranged in a direction of flow of the fluid stream through the vaporizer for vaporizing liquid in the fluid stream in stages. The heat exchangers each comprise a first plurality of thermally conductive flow channels through which the fluid stream flows and a second plurality of thermally conductive flow channels through which a heating stream flows and which are in heat exchange relationship with the first plurality of thermally conductive flow channels. A liquid supply means is provided for adding liquid to a downstream heat exchanger. The added liquid mixes with the vaporized stream exiting an upstream heat exchanger for vaporization in the downstream heat exchanger.

A heat exchanger design is provided for optimal transfer of thermal energy between a primary reactor-out reformate and a primary reactor-in steam and air. In particular, one embodiment of the present invention comprises a prime-surface true counterflow heat exchanger positioned around the primary reactor. It is emphasized that this abstract is provided to comply with the rules requiring an abstract, which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that is will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1. 72().

Two types of optical liquid level sensor are disclosed. In the first refractive-type (20,65), light is selectively refracted by the particular fluid(s) in a plug recess between primary and secondary detectors (D. sub. 1,D. sub. 2). The output signal from either detector indicates whether the sensor is above or below the liquid level. The signals of the respective detectors are cross-compared and used to corroborate one another. In the second absorptive-type (100), light at a particular wavelength is passed through a body chamber (86'), which is exposed to the liquid whose level is to be sensed. Such light is selectively absorbed by the liquid. A detector (D) is arranged to measure the intensity of such light as has passed through the chamber, and to indicate the level of liquid in said chamber.
