Alonizing process

Processes and/or unit operations that fall under this classification include adsorption, ion exchange, stripping, chemical oxidation, and membrane separations. All of these are more expensive than biological treatment but are used for removal of pollutants that are not easily removed by biomass. Often these are utilized in series with biologic treatment but sometimes they are used as stand-alone processes. 

VX projectiles and rockets coprocessing, (4) VX rockets alone (after all VX projectiles are gone), and (5) HD projectiles alone. Processing rates have been selected, as shown in Table 5-6. 

ATR is a stand-alone process which combines POX and SR in a single reactor. The ATR process was first developed in the late 1950s by Topsoe, mainly for industrial synthesis gas production in ammonia and methanol plants [27].

Concerns about groundwater contamination and municipal water supply quality have driven much of the growth of various water treatment schemes involving nanofiltration as a stand-alone process or in combination with RO and/or UF in a broad range of water treatment systems delivering precise purity levels and attractive process economics. Other established applications include corn syrup concentration, recycling of water-soluble polymers, effluent treatment for the food and beverage industry, metal... 

Several different peroxygen-based systems exist, all of which are compatible with biological treatment. The peroxygen treatment can be used up- or downstream of the biotreatment unit, either as a pre-treatment to reduce toxicity and improve biodegradability or as a post/polishing treatment to remove remaining biorecalcitrant species from the effluent. All the peroxygen-based treatments can also be used as stand-alone processes for the total treatment of a waste stream. The most common AOPs are ... 

The stand alone process allows the direct production of high purity paraxylene. It works similarly to the process described in section 10.3.2.3. Generally two adsorbent towers of 12 beds each are required to achieve high performance... 

Metal coupons were inserted at various positions in the horizontal tubular reactor. The coupons had two types of surfaces an Incoloy 800 surface and an aluminized Incoloy 800 surface. To prepare these coupons, flat pieces of Incoloy 800 were aluminized (or alonized) by the Alon Processing, Inc. of Tarentum, PA. In this process, gaseous aluminum was contacted with the Incoloy 800, and aluminum diffused into the surface. The alonized samples as received from Alon Processing were cut in small coupons so as to expose an Incoloy 800 surface which was cleaned and polished before use. 

The pyrolysis reactors were similar to those used earlier (1,2) they were 1.1 to 1.26-cm i.d. tubes that were heated in an electrical resistance furnace over a length of about 48 cm. The materials of construction in the four reactors used in this investigation were as follows Incoloy 800, stainless steel 304, Vycor glass, and alonized Incoloy 800. The latter reactor was prepared by Alon Processing, Inc. of Tarentum, Pennsylvania. 

Though MD has provoked intense research activity that has led to numerous publications and patents, it finds relatively fewer commercial applications as a stand-alone process, as compared with other membrane processes. 

This option was tested and did not work as a stand-alone process because the DMSO was too dilute in these impurities. The measured adsorption isotherms indicated that unrealistically large amounts of adsorbent would be required, even for marginal results. 

For these reasons, it was evaluated as more cost-effective to implement the process in a dedicated unit optimized for renewable feedstocks to overcome the problems listed above. Therefore, the Ecofining technology is a stand alone process carried out... 

The present results support the general conclusion by Baker and Chludzinski (10T that certain surfaces can minimize coke formation on the surface. In the present case/ aluminized stainless steels as prepared by Alon Processing/ Inc. retained their surface characteristics over at least two coking sequences. It is known in addition that a tube prepared by Alon Processing was used successfully in an ethylene coil for at least a year and that appreciable aluminum was still present on the surface at the... 

Acknowledgment is made to the donors of the Petroleum Research Fund/ administered by the American Chemical Society, for partial support of the research. Alon Processing/ Inc. of Tarentum. PA also provided support. 

Alon Processing. Inc. provided financial support to the present investigation. 

Depending on the composition of the waste and its discharge or reuse requiranents, the following treatment processes can be applied, as stand-alone processes or as part of a treatment regimen ... 

Alonizing Process—diffusion of alvuninum into steel to form an iron-aluminum alloy, Alon Processing, Inc., Tarentum, Pennsylvania. 

In an effort to solve the problem of carbon fonna-tion without resorting to the use of high cost stainless steels, a sample of chrome-moly steel ws subjected to the alonizing process (aluminum impregnation). Table VII demonstrates the successful pacification of the surface ... 

Good. Part of technology package to dispose of stockpile chemical munitions that can be a stand-alone process for nonstockpile CWM can process either neat agent or neutralent. 

There are about 700 operational oil refineries in the world. A medium-sized refinery can typically process 100,000 barrels of oil per day. Jamnagar refinery in Gujarat, India, is currently the biggest refinery in the world it alone processes more than 1% of global output. The top 10 biggest refineries in the world are listed in Table 12.1. 

Extractive desulfurization (EDS) probably will be economically attractive as a stand-alone process in some refinery applications. However, it seems likely that many refineries also will look to employ a synergistic combination... 

In addition to its potential as stand-alone processes for ULSD production, the EDS processes, therefore, may find application as ancillary process units for the debottlenecking of HDS units by ... 

It should be noted that SwS is not the same as software reliability or SQA, and it cannot be achieved solely through these processes. The SwS methodology involves an independent stand-alone process that must be integrated with the software development process. The SwS process should be established at the start of a project and be documented in the SwSPP. The SwS program implements the SwSPP and carries out the SwS process.
