Inventor: GULLICHSEN JOHAN ERIK
IPC: B01D19/00
Filed: 1982-06-07
Abstract: Pulp degassification is effected by a structure (10) that may be mounted on a pulp treatment vessel (12), such as an oxygen reactor blow tank. The degassifier includes a housing (14) that is substantially circular in crosssection end tapers from a first end (15) to a second end (16) along a central axis. A pulp inlet (20) is adjacent the first end and introduces pulp tangentially and an outlet (24) is adjacent the second end extending concentrically with the central axis. A blade assembly (26) is mounted for rotation about an axis (A-A) generally coincident with the housing central axis, and the blade assembly is rotated to impart a high speed rotational velocity component to the pulp as it enters the housing. A gas outlet (40) is adjacent the housing first end, vertically above the housing second end, and adjacentthe central axis. A conically shaped baffle (44) or the like is provided surrounding the gas outlet to prevent short-circuiting of pulp from the inlet to the gas outlet.

Abstract: A process for producing pig iron from iron ore concentrate, at which in a reactor vessel iron ore concentrate, coal, oxygen gas and slag formers are injected beneath the surface of a molten iron bath. According to the invention, the ratio CO2/CO in the waste gas (11) from the reactor (2) is caused to increase to a value higher than corresponding to the condition of equilibrium at atmospheric pressure. Hereby a greater heat development is caused to take place in the bath for a certain coal amount. The injected amount of coal in relation to injected amount of concentrate is predetermined to be sufficient for finally reducing pre-reduced iron ore concentrate (4) in the reactor (2). According to the invention, CO and H2 in the waste gas is passed to a pre-reduction step (1), where unreduced iron ore concentrate is pre-reduced and thereafter can be injected into the reactor. 
<??>According to a preferred embodiment, the reactor (2) is pressurized to cause the CO2/CO ratio to increase.

Abstract: ''FORMULAçãO APERFEIçOADA PARA CONCENTRADO DE ADITIVO DE FERTILIZANTE''. Sistemas solventes para a formulação de inibidores de uréase de triamidas N-alquil tiofosfóricas. Estas formulações possibilitam a preparação de soluções concentradas estáveis de triamidas N-alquil tiofosfóricas para armazenamento, transporte e impregnação eventual sobre fertilizantes contendo uréia sólidos e a incorporação nas composições de fertilizantes contendo uréia líquidas. Essas formulações são compreendidas, basicamente, de um solvente selecionado do grupo consistindo de glicóis e derivados de glicol. Opcionalmente, a formulação também pode conter pelo menos um outro solvente pertencente ao grupo consistindo de amidas líquidas, 2-pirrolidona e N-alquil 2-pirrolidonas e/ou um tensoativo não iónico selecionado do grupo consistindo de poli (éteres-álcoois de alquilarila). Verificou-se que presença do co-solvente e/ou tensoativo confere as propriedades desejáveis às formulações sob determinadas condições. As triamidas N-alquil tiofosfóricas são conhecidas há algum tempo como sendo inibidores efetivos da atividade das enzimas de uréase, embora, o uso comercial tenha sido inibido pela falta de um veículo aceitável. São, freq³entemente, térmica e hidroliticamente instáveis e difíceis de manusear. O uso dos sistemas solventes oferece várias vantagens, tais como: (1) estabilidade aperfeiçoada do inibidor de uréase do ingrediente ativo; (2) excelentes caracterísiticas de solubilidade; (3) inflamabilidade e toxidez extremamente baixas dos solventes, o que simplifica bastante o manuseio e o armazenamento do concentrado; (4) excelentes características de armazenamento em baixa temperatura, com a adição do co-solvente de amida líquida e (5) boas características de adsorção sobre os fertilizantes contendo uréia sólidos e excelente miscibilidade com as formulações de fertilizantes contendo uréia líquidas.
