Process Licensors. Some of the well-known nitric acid technology licensors are fisted in Table 3. Espindesa, Grande Paroisse, Humphreys and Glasgow, Rhfyne Poulenc, Uhde, and Weatherly are all reported to be licensors of weak acid technology. Most weak acid plant licensors offer extended absorption for NO abatement. Espindesa, Rhfyne Poulenc, Weatherly, and Uhde are also reported (53,57) to offer selective catalytic reduction (SCR) technology. 

BYAS [Bypass ammonia synthesis] An economical process for expanding existing ammonia synthesis plants by introducing the additional natural gas at an intermediate stage in the process. The additional nitrogen in the air, which has also to be introduced, is removed by PSA. Developed and offered by Humphreys and Glasgow, UK. 

CPG [Clean Power Generation] A version of the IGCC process which incorporates the Texaco coal gasifier. Developed and offered by Humphreys and Glasgow. 

In practice to-day there are two methods of making er gas, one the English or Humphrey and Glasgow...

Sulpel [Sulphur pelletization] A process for making sulfur pellets. Molten sulfur is injected through nozzles into water containing a trace of a proprietary additive, which gives the resulting pellets a smooth, waterproof surface. Developed and offered by Humphreys and Glasgow, UK nine plants had been engineered as of 1992. 

Conventional processes CF. Braun, Fluor, Humphreys and Glasgow (Lead and MDF processs), KeOogg, Lummus, etc. 

An indirect method to convert methanol selectively into ethanol has been reported recently by Halcon [61] and Humphreys and Glasgow/ BASF [62]. In the first stage methanol is carbonylated according to eq. (1) to give acetic acid, which is subsequently hydrogenated to ethanol as shown in eq. (30) ... 

While in the Halcon SD process a non-noble metal halide catalyst is used for methanol carbonylation, and acetic acid is converted to methyl acetate prior to hydrogenation, the ENSOL process of Humphreys and Glasgow/ BASF utiUzes the rhodium/iodide-based Monsanto technology to produce acetic acid which is directly hydrogenated to ethanol. For the ENSOL process an overall thermal efficiency of 50% and a carbon efficiency of 74% is claimed for the conversion of natural gas into ethanol [62]. 

The genesis of the LO-CAT process is found in the early work by Humphreys and Glasgow in London. The initial British process, named the C.I.P. (Chelated Iron Process), used Ethylene Diamine Tetra Acetic Acid (EDTA) to keep the iron in solution. The first application of the process in an oil refinery in Landarcy, Wales, in 1964, was unsuccessful because of the instability of the chelated iron solution. The instability problem was due to a combination of two factors The precipitation of hydrated iron oxides at elevated pH, and the degradation of the chelating agent over time (Meuly and Ruff, 1972 Meuly. 1973). 

Contractors offering downfired furnaces for methanol applications include ICI licensees, such as Davy Technology (division of John Brown) and Humphreys and Glasgow, Uhde, KTI, and The M. W. Kellogg Company. (See Figs. 25 and 26.)...
