Title: Thermally-insulated pipe string
Inventor: FEDOSEEV A V
IPC: E21B36/00
Filed: 1995-12-13
Granted: 1998-06-10
Abstract: FIELD: oil and gas production industry. SUBSTANCE: this can also be used in other industries for thermal insulation of pipelines. Space created between plunger and inner pipe is filled with thermal-insulating material. Rigidly secured is guiding steady rest which is movable in inner tube. After that, inner pipe together with housing-plunger is inserted into outer pipe with flange and sealing unit. Installed on upper end of inner pipe is cap-body carrying preliminarily installed and clamped down sealing device. Cap-body is secured to flange of outer pipe of first section of string. This is done after connecting final section to sinking intermediate section and lower section of thermally-insulated pipe string. This string is rigidly secured by installing it on casing pipe at well head through flange of string outer pipe. Ready thermally-insulated sections are connected together to produce string which is lowered into well in same procedure as applied to pump-and-compressor pipes. In this case, initially coupled are inner pipes of sections, and placed at joint of two sections between guiding steadyrests is thermal-insulating material. Then, after preliminarily lowering of outer pipe, it is connected by means of power-operated pressure nut with tipping coupling sleeve, with nut located on upper part of outer pipe of string, and they are tightly clamped together, so as to seal off coupling joint of string section. EFFECT: higher efficiency. 2 cl, 5 dwg

Title: Method of recovering mono-and diethylene glycols from stillage residue resulting from process of recovery of monoethylene glycol
Inventor: SAFIN D KH
IPC: C07C31/20
Filed: 1996-08-19
Granted: 1998-05-27
Abstract: FIELD: chemical industry. SUBSTANCE: present invention describes method of treatment of stillage residue resulting from process of rectifying monoethylene glycol recovered from aqueous solution of ethylene glycols formed as by-product in ethylene oxide production by addition of triethylene glycol or tetraethylene glycol or mixture thereof in amount of 10.0-30.0 wt % to stillage residue to be treated, and the desired products are then recovered by vacuum rectification. Addition of tri-and tetraethylene glycols to said stillage residue causes mobility of the resulting stillage liquid when mono-and diethylene glycols are recovered from said stock and excludes formation of solid precipitales of alkali metal salts in said stillage liquid. In order to reduce costs for treatment of said stock, tri-and tetraethylene glycols should be desirably replaced by stillage residues resulting form rectification of di- and triethylene glycols resulting from desired synthesis of monoethylene glycol by reaction of hydration of ethylene oxide. Use of the claimed method affords high degree of recovery of mono-and diethylene glycols from said product and solves problem of utilization of stillage residues resulting from rectification of monoethylene glycol. EFFECT: more efficient recovery method. 2 cl, 1 dwg , 1 tbl
