Texaco-process, partial oxidation

Strelzoff, S. (1974), Partial oxidation for syngas and fuel (comparaison des precedes Texaco, Shell et Union Carbide) . Hydrocarbon processing, Vol. 53, No. 12, p. 79. [Pg.459]

The Texaco process was first utilized for the production of ammonia synthesis gas from natural gas and oxygen. It was later (1957) appHed to the partial oxidation of heavy fuel oils. This appHcation has had the widest use because it has made possible the production of ammonia and methanol synthesis gases, as well as pure hydrogen, at locations where the lighter hydrocarbons have been unavailable or expensive such as in Maine, Puerto Rico, Brazil, Norway, and Japan.

Heavy Hydrocarbon-Based Partial Oxidation Processes. Two major partial oxidation processes are commercially available, the SheU process (38) and the Texaco process (39). Operating conditions in the gas generator vary from 1200°C to 1370°C and from 3100 kPa to 8270 kPa (450—1200 psig). Generally, heavy oils are the hydrocarbon feeds however, the process can also accommodate feeds from natural gas to residual oils. [Pg.342]

The saturated, cleaned raw synthesis gas from a Texaco partial oxidation system is first shifted by use of a sulfur resistant catalyst. Steam required for shifting is already present ia the gas by way of the quench operation ia the generator. The shifted gas is then processed for hydrogen sulfide and carbon dioxide removal followed by Hquid nitrogen scmbbiag. [Pg.343]

The Texaco gasification process is a partial oxidation gasification process for generating synthetic gas, principally hydrogen and carbon monoxide. [Pg.404]

ER E has studied these alternatives for the utilization of coal liquefaction bottoms in the production of hydrogen and fuel gas and in doing so has had discussions of partial oxidation with Texaco and Shell. These studies have identified a potentially attractive processing sequence utilizing FLEXICOKING to produce additional liquids and plant fuel, and partial oxidation to produce hydrogen. [Pg.87]

Both FLEXICOKING and partial oxidation are commercial processes for petroleum residue (12,13). In addition, partial oxidation has been utilized to generate Synthesis gas with coal as a feed (14,15). Coal liquefaction bottoms have been processed in small pilot units in recent studies including Exxon s 2 B/D FLEXICOKING pilot plant (3) and Texaco s 12 T/D partial oxidation unit (16). Studies in Exxon s unit have included EDS bottoms from Illinois and Wyoming coals while SRC-I, SRC-II, H-Coal and... [Pg.87]

ER E discussions with Texaco and with Shell on bottoms processing are summarized herein. Texaco has indicated that its partial oxidation process could be applied to coal liquefaction bottoms on a commercial scale and that operation of their 12 T/D pilot plant with coal liquefaction bottoms representative of a projected commercial feedstock would be adequate to set the design basis for a commercial facility. Texaco indicated that three to four years after successful operation of the 12 T/D unit a commercial facility could be ready for startup. In initial discussions, Shell has indicated that development of the Shell/ Koppers partial oxidation process for coal liquefaction bottoms would involve operations of both their 6 T/D pilot plant and their 150 T/D demonstration unit. It was estimated that the 150 T/D facility might become available in the late 1980/early 1981 time frame for possible operation on vacuum bottoms. [Pg.89]

The Entrained system is a high temperature, high reaction rate process in which coal, oxygen (or air) and steam combine rapidly to produce LBG or MBG. The commercial processes aim primarily at the use of oxygen. Several developmental processes use oxygen or air. The most widely used commercial process (Koppers-Totzek) is operated at atmospheric pressure. The Texaco partial oxidation process used with oil and gas is under development for use with coal. Shell and Koppers are developing a pressurized version of the current Koppers-Totzek process. The advantages of the entrained... [Pg.185]

Non-catalytic partial oxidation (POX) of hydrocarbons from residual fuel oils to methane is commercially proven by two processes, one offered by Texaco and the other by Shell. Davy has experience with both processes. Each process has a large number of plants in operation, with feeds varying from natural gas to high sulfur residual oil. (In fact, so long as the feedstock can be pumped, it is a suitable feestock for a partial oxidation gasifier. [Pg.148]

Techniques of partial oxidation of petrolenm cuts, which are generally thermal and use burners (Texaco Shelly Some of them use contact masses whose catalytic effect is claimed by the process licensors ONIA GEGI Office National des Indusp-ies de VAzote MontecatinU Koppers Totzek). However, the Ugh temperatures employed and the danger of carbon deposits on the contact mass do not favor the spread of these technologies. [Pg.32]

The current producers of partial oxidation processes are BASF, Texaco, Shell, and Hydrocarbon Research. A process block diagram showing the three process steps can be seen in Figure 2.18 [30]. The first step is the gasification process with the addition of oxygen and water. A detailed schematic of the Shell Gasification plant (SGP) is shown in Figure 2.19 [28]. The most important features of the process are the reactor, waste-heat-boiler, carbon catcher,... [Pg.53]

Partial oxidation is another important method to convert the petroleum feedstocks to methane rich synthetic gas [20], There are three well-developed commercial processes available in the market the Shell Gasification Process (SGP), the Texaco Gasification Process (TGP), and the Ube Process. In the following text a description of the SGP is presented and this process is compared with the TGP. A description of the Ube process is not included. [Pg.328]

TABLE 1.3 Process conditions for Co-Mo catalysts based water-gas shift reactor for Texaco partial oxidation process... [Pg.17]

The commercial Co-Mo catalysts operate in the temperature range 250-350 °C and at pressures from atm to 40 bar. The typical process conditions for a Texaco partial oxidation process that generate syngas from heavy oil which use sour Co-Mo WGS catalyst are shown in Table 4.3. Three Co-Mo catalysts beds are used. The syngas from partial oxidation reactor contains 0.25% of H2S. The inlet CO concentration of 46% is reduced to 1% at the exit of third bed. However, the Co-Mo catalyst converts H2S and CO into COS. Hence, COS hydrolysis has to be performed after the water-gas shift reaction. However, if we... [Pg.120]
