Brown, P. et al., Offshore Engineer, Apr. 1995, p. 38. A number of options are being considered for extending the production life of BP’s Magnus field, which has been producing oil and gas from platform and subsea wells for over a decade. First component of the overall Magnus Exploitation Project is the Swift (subsea water injection facilities and tieback) project, whose key features are described by three members of the project team.

Effects of ovrolvsls conditions on Internal surface areas and densltles of coal chars prepared at hlgh heating rates In reactive and nonreactive atmospheres
&i/Q3374
Gale, T. K. et al., Energy & Fuels, May-Jun. 1995, 9, (3), 5131524. Concern about comparability and validity of different methods for producing coal chars for research has motivated this investigation of the effects of devolatilization conditions on the physical properties of coal chars. It is evident from the finding of this study that care must be taken to prepare char oxidation studies. Two different entrained flow reactors were used to prepare chars under a variety of different pyrolysis conditions at maximum particle temperatures between 840 and 1627 K and heating rates between lo4 and 2 X lo5 K/s.
Full scale treatment of phenolic coke coking waste 95103375 water under unsteady conditions
Suschka, J. et al., Water Sci. Technol., 1994, 29, (8), 69-79. The paper describes how the phenolic wastewater from the largest coking plant in Poland is treated at a full technical scale. From the very beginning it became evident that very high qualitative variations in short and long periods are to be expected. For this purpose, the biological treatment plant based on activated sludge is protected through preliminary physical-chemical treatment and the results are secured by a final chemical stage of treatment. The experienced gained over the last five years is described and improvements are presented.

A process where liquid hydrocarbons are blown into red-hot cokes under controlled liquid drop and blowing rate conditions so that the hydrocarbons are vaporized just before reaching the cokes. The process obtains metallurgical cokes with high cold strength and low thermal reactivity with CO,.
Offshore En ineer, Apr. 1995, 65, 67-68. The world’s f:lrst commercial subsea multiphase boosting system is a reality, following the successful start-up and early operation of Smubs - the Shell multiphase underwater booster station, on Norske Shell’s Draugen field. The results have seen significantly increased production from the Rogn South subsea production well.
Explanation of product distribution of hydrocracking reaction of aromatic hydrocarbons with nickel-loaded zeolltes based on CAMD study on interaction between zeolites and substrates 95/033&I
Matsui. H. et al., Energy & Fuels, May-Jun. 1995, 9, (3), 435-438. Simulaiion of difiusion &enomena of arbmatic hydrbcarbdns in the channel of three different zeolites (ZSM-5, mordenite, and Y-type zeolites) was carried out by using a commercial CAMD (computer-aided molecular design) software. The diffusion phenomena of model aromatic hydrocarbons, such as benzene, naphthalene, phenanthrene, and pyrene, were found to depend greatly on molecular sizes of both the channel of these zeolites and model compounds. The relationship between such diffusion phenomena in the zeolites and product distribution of these aromatic hydrocarbons in hydrocracking reaction is briefly discussed.

Reports on Monohulls which are still rare as production units in the North Sea, and all of them so far operating or planned are newbuilds - except one. This summer, the UK Fife field will go on stream through a converted tanker which represents the most ambitious floating production project yet undertaken by specialist Bluewater. The author reports on the project and profiles the company. 95103387

The process comprises delayed coking of coal-tar pitch to contain a raw coke, screening the raw coke to give a granular part, and a powder part, baking the granular part at SOO-lsb0” and cooling, baking the~powder~part at 1050-1450” 10 minutes or longer, and then mixing the 2 parts and rebaking at 1500-1800’ 10 minutes or longer to obtain a high-quality needle coke. Production of foundry coke in large capacity ovens 95103379 of Altal coke olant
Unterberger, O.‘G. et al., Koks Khim., 1994, (9), 11-16. (In Russian) The coking plant of interest has ovens with a capacity of 41.6 m3 and 410 mm wide. To produce foundry coke in these ovens, coal charges should contain 78% particles c3 mm. The reactivity of this coke is decreased 50% by changing coal charge properties, which decreases its consumption during casting by l-4%.
