IPC: D21F3/08
Filed: 1987-04-01
Abstract: A pulp dewatering apparatus is constructed of two press rolls arranged juxtaposed to define a nip region. At least one of the press rolls is constructed of a perforated metal outer shell surrounding a substantially rigid inner roll body. A layer of elastic material is disposed between the rigid roll body and the perforated metal shell to provide a resilient member. As a result of the elastic material, this press roll will deform during the dewatering operation to provide an extended nip region of about 3 to 5% of the overall press roll diameter.

IPC: B65D83/14
Filed: 1988-05-20
Abstract: A flexible gas-tight, hermetically sealed pouch (11), in which a likewise closed cartridge (8) filled with a propellant in the liquid phase is disposed, is introduced into the outer envelope (1) of a container (1a), and the container (1a), which includes a valve (7) for distributing fluid (13) contained in it or introduced via the valve (7) is plugged. The cartridge (8) used has a wall capable of degrading at least partially from simple contact with the propellant, until the cartridge opens, within a period of time at least equal to that necessary to assure the packaging and closure of the container (1a ). The propellant then spreads within the pouch (11), changing at least in part to the gaseous phase, at a pressure suitable to assure the dispensing of the fluid (13). By the judicious choice of the characteristics (type, thickness) of the degradable zone of the cartridge (8), heating or other more complicated or expensive means proposed heretofore for putting the container under pressure are avoided.

Abstract: Secondary pulp is deinked and bleached by contacting the pulp simultaneously with oxygen, alkali, and a surfactant in a reaction zone followed by washing to recover a secondary fiber product. Simultaneous contacting with oxygen and surfactant yields higher pulp brightness than sequential contacting in oxygen bleaching and washing stages, and enhances bleachability in further bleaching stages.

Abstract: The invention relates to a method for packing bitumen, especially road bitumen, in bulk disposable transport units for the cold transportation of bitumen. The aim of the invention is to be able to fill and recycle such disposable transport units (13) in a targeted manner. To this end, said disposable transport units are produced from a flexible plastic material having a melting point of between 20 DEG and 50 DEG C above the softening point of the bitumen, the bitumen being cooled almost to the softening point of the respectively processed bitumen before the units are filled. The invention also relates to an installation for carrying out said method, said installation comprising a plate heat exchanger (6) for cooling the bitumen, at the output of which a temperature difference between the coolant and the bitumen is maintained between 10 DEG and 25 DEG C.

Title: Additives to enhance metal and amine removal in refinery desalting processes
Inventor: NGUYEN TRAN M
IPC: C10G33/04
Filed: 2003-08-28
Abstract: It has been discovered that metals and/or amines can be removed or transferred from a hydrocarbon phase to a water phase in an emulsion breaking process by using a composition that contains water-soluble hydroxyacids. Suitable water-soluble hydroxyacids include, but are not necessarily limited to glycolic acid, gluconic acid, C 2 -C 4  alpha-hydroxy acids, poly-hydroxy carboxylic acids, thioglycolic acid, chloroacetic acid, polymeric forms of the above hydroxyacids, poly-glycolic esters, glycolate ethers, and ammonium salt and alkali metal salts of the hydroxyacids, and mixtures thereof. The composition may also include at least one mineral acid to reduce the pH of the desalter wash water. A solvent may be optionally included in the composition. The invention permits transfer of metals and/or amines into the aqueous phase with little or no hydrocarbon phase undercarry into the aqueous phase. The composition is particularly useful in treating crude oil emulsions, and in removing calcium and other metals therefrom.
