The flow diagram for a rich gas plant producing gas with a calorific value of 710 Biu/slandard cubic foot is shown in Fig. 1. The product is used to enrich lean gas from an IC1 (Imperial Chemical Industries) naphtha reformer which has a calorific value of about 320 Btu/standard cubic foot to the town gas standard of 500 Btu/standard cubic foot (56 Calories/cubic meter). Typical gas analyses arc given in Table 1. 

The preliminary simplified principal flow diagram of the MHR-T module (option with methane reforming) is given in Figure 3. The flow diagram for the option with water steam electrolysis may differ by components of intermediate helium circuit between RP primary circuit and chemical-technological sector.

A typical process flow diagram of a catalytic reformer is shown in Figure 3.17. Desulfurized naphtha is heated in feed-effluent exchangers and then passed to a fired heater, where it is heated to 850 to 1,000° F (455 to 540° C) at 500 psia (3,450 kPa) in a series of reactors and fired heaters. In the reactors, the hydrocarbon and hydrogen are passed over a catalyst (often platinum/rhenium based) to produce rearranged molecules, which are primarily aromatics with some isoparaffins. The reactor effluent is cooled by exchange and then passed to a separator vessel. The gas from the separator is recycled to the reactors. The liquid is fed to a fractionator.

A schematic flow diagram of the biomass pyrolyzer-reformer designed and constructed for Phase 2 is shown in Figure 3. The pyrolyzer is designed to process up to 188 lbs (85 kg) per hour of pelletized biomass into char and pyrolytic off-gas. 

The flow diagram for a steam methane reformer is illustrated in Figure 3, This is a conventional reformer designed to maximize the production of hydrogen, A plant designed for production of syngas or carbon monoxide would not include the high and low temperature shift converters and the... 

A simplified flow diagram of ATR process is shown in Figure 8 [14]. Preheated hydrocarbon feed and oxygen mixed with a small amount of steam enter the top of the reformer reactor. Partial combustion takes place in the... 

Figure 11 Oxygen secondary reforming block flow diagram.

A process flow diagram depicting the main features of an oxygen secondary reformer is shown in Figure 12 [6]. The process is a conventional steam reformer with the secondary reformer reactor and direct contact water quench downstream of the primary reformer.
