Title: Stabilisation and use of heterogeneous liquid compositions
Inventor: CHAMBERLAIN PETER
IPC: C09K23/00
Filed: 1994-09-15
Abstract: An oil in water emulsion comprises a continuous aqueous phase and a discontinuous oil phase which is either a hydrophobic liquid which is immiscible with the aqueous phase or is a solid phase obtained by providing an emulsion in the aqueous phase of a solution of potentially solid material in the hydrophobic liquid and converting this solution to a solid phase, and the emulsion is stabilised by the inclusion of water-soluble stabilising polymer in the aqueous phase and oil solubilising stabilising material, generally polymer, in the oil phase. The or each polymer is preferably a copolymer of hydrophilic and hydrophobic groups, preferably being formed by copolymerisation of water-soluble monomer and oil-soluble monomer that provide the desired groups in the polymer without further reaction.

Title: Ammonia production with enriched air reforming and nitrogen injection into the synthesis loop
Inventor: LEBLANC JOSEPH RAY
IPC: C01B3/02
Filed: 1996-08-26
Abstract: A retrofit method for increasing production capacity of an ammonia plant having a front end including in series primary and secondary reformers and a shift converter for reacting a hydrocarbon feed, steam and air to form a make-up syngas stream comprising hydrogen and nitrogen at about design stoichiometry, and a synthesis loop wherein a recycle syngas stream is combined with the make-up gas to form a syngas feed to ammonia converters. The retrofit involves the installation of an air separation unit to supply oxygen and nitrogen streams. The oxygen is used to enrich air supplied to the secondary reformer and increase the hydrogen content of the make-up gas substantially above the design stoichiometry and capacity. The nitrogen stream is supplied to the synthesis loop to obtain a desired hydrogen to nitrogen ratio in the syngas feed to the ammonia converters and compensate for the excess hydrogen in the make-up gas. The synthesis loop, if desired, is upgraded to include a high activity catalyst converter for increased ammonia production.
