Scale tiodel of the $8.4 million fertilizer works being built by Scottish Agricultural industries at Leith on l a n d reclaimed by t h e L e i t h Dock Commission
Scottish Fertilizer Works A n e w fertilizer plant is being built b y Scottish Agricultural Industries at Leith. Cost of the entire project, including reconstruction work at the existing fertilizer works, is expected to b e approximately $8.4 million. T h e new factory will produce granular concentrated compound fertilizers on a large scale. T h e site (land reclaimed by the Leith Dock Commission) is situated to give a deep water berth to the west and a large railway marshalling yard to the southeast. A main feature is a 907 foot long by 100 foot wide storage building which will house some 56,000 tonj of raw materials. T h e works will consist of a SimonCarves/Monsanto sulfur burning contact sulfuric acid plant with a rated capacity of 175 tons per day. Waste h e a t from combustion of sulfur will produce high pressure steam at a rate of 17,000 pounds p e r hour. A second main process plant will manufacture phosphoric acid from phosphate rock a n d sulfuric acid by the Prayon reaction process. Waste gypsum will b e extracted from the phosphoric acid m a g m a by vacuum filtration. A triird process building will b e used to p r o d u c e the finished fertilizers.

Boots Cortisone Plant on Stream Cortisone (acetate), hydrocortisone, and delta-hydrocortisone are being produced in BoOv- Pure D r u g n e w Beeston plant, just outside of Nottingham, England. With emphasis o n safety, ail operations presenting any inherent fire hazards are conducted in t h r e e smaller buildings. This involves certain testing, process stage involving lithium aluminum hydride, a n d preparation of sodium medioxide. Illumination for latter operation comes entirely from outside lighting. Lithium aluminixrn hydride building is constructed in t w o halves so t h a t operators can supervise and remotely control actual operations occurring · in second half.
