In 1997, UOP announced the PX-Plus process which also uses a selectivated catalyst to convert toluene to para-rich xylenes. Pina commercialized a TDP process known as the (T2PX) process in 1984 (70). It uses a proprietary catalyst to react toluene at 42—48% conversion with selectivities to benzene of 42 wt % and to xylenes of 46 wt %. The xylenes produced are at equiUbrium. Typical commercial operating conditions of 390—495°C, H2 partial pressure of 4.1 Mpa, H2/hydrocarbon molar ratio of 4 1, and LHSV of 1—2/h. Pina s first commercial implementation occurred in 1985 at their Port Arthur refinery. 

Toluene demand in 1996 increased because of the new Amoco and Mobil (Chalmette) disproportionation plants as well as other capacity changes at Coastal (Eagle Point), Phillips (Sweeney), Gulf Chemicals (Arochem plant, Puerto Rico), Koch, and Texaco (Huntsman, Port Arthur). Dewitt (71) forecasts continued increase for this appHcation at the rate of about 14% between 1995 and the year 2000. These will have a significant effect on toluene price and availabiUty in the later 1990s. On the other hand, toluene demand for gasoline blending is expected to decline by about 283 million Hters by 1997-1998.

The first and second highest annual average nickel concentrations in the air in Texas between 1978 and 1982, according to the Texas Air Control Board, were 49 and 34 ng/m at Port Arthur and Beaumont, respectively (Wiersema et al. 1984). The statewide 1978-1982 average was 1 ng/m. Mean nickel levels showed relatively little geographic variation in Ontario where concentrations in southern, central, and northern Ontario were 0.81, 0.91, and 0.58 ng/m, respectively (Chan et al. 1986).

The control scheme shown in Fig. 17.4 is certainly quite common. But is it the best Figure 17.5 is a copy of the crude charge system in a now-defunct refinery in Port Arthur, Texas. I saw it in operation many years ago. It worked fine. The required flow of crude directly controls the governor. The turbine speed is then always at its optimum. The AP across the process-control valve is always zero, because there is no process-control valve. This design is a direct descendant of the original method of controlling the steam flow to pumps. The steam inlet valve was opened by the operator, so that the desired discharge flow was produced. 

The pump shown in Fig. 25.8 is an illustration of an installation in Port Arthur, Texas. The difficulty with this pump was that it would lose its prime after being shut down for just a few moments. What is the problem ... 

To fix this problem in Port Arthur, I connected an external source of seal flush water to the pump, from a nearby washwater station. Pumps which have subatmospheric suction pressures, and which are not in continuous service, should not be self-flushed pumps. They should have an external source of seal-flush material connected to the mechanical seal.
