COMPARATIVE STUDY OF HIGH PRESSURE AND …

The purpose of this study was to compare the high pressure acid leaching (HPAL) with agitated atmospheric leaching (AL) to obtain better extraction efficiencies of nickel and cobalt from refractory nickel laterite ores of Gördes.

SYNTHESIS AND OPTIMIZATION OF DEMETHANIZER …

The process performance is strongly dependent on the operating pressure of the distillation column. At medium to low pressures, i.e. 2000 kPa or lower, the recompression horsepower requirement will be so high that the process becomes uneconomic. However, at higher pressures the recovery of

Article Research on high-pressure hydrochloric acid ...

high-pressure leaching using HCl and H 2 SO 4 have shown that high-pressure hydrochlo-ric acid leaching allows to extract more than 90% Al and above 95% Y, La, and Nd, as well as up to 80% Sc with the co-dissolution of Si and Ti below 5% [29]. The use of hy-drochloric acid for HPAL for the aluminum extraction in different high-silica materials,

The high-pressure column C2 has 16 stages and the distillate from C1 is fed on Stage 6 after being preheated by the bottoms stream from 43 °C to 124 °C (634 kW). The pressure is 11.3 bar, which gives a base temperature of 167 °C …

ALTERNATIVE FLOWSHEETS FOR THE SULFUR-IODINE ...

One of the most promising cycles for the thermochemical generation of hydrogen is the Sulfur-Iodine (S-I) process, where aqueous HI is thermochemically decomposed into H2 and I2 at approximately 350 degrees Celsius. Regeneration of HI is accomplished by the Bunsen reaction (reaction of SO2, water, and iodine to generate H2SO4 and HI).

A proposal of the nip zone angle determination in high-pressure grinding rolls (HPGR) crushing process is presented in the paper. Knowledge of the nip zone angle value makes it possible to ...

Flowsheets - an overview | ScienceDirect Topics

Flowsheets may be drawn by hand at preliminary stages of a project, but with process simulators and CAD software packages, it is a simple matter to develop flowsheets with a consistent set of symbols for equipment, piping, and operating conditions contained in software packages. There is no generally accepted set of standards, although attempts have been made with little success.

ALTERNATIVE FLOWSHEETS FOR THE SULFUR4ODlNE …

The Sulfur-Iodine cycle was studied extensively in the 1970's and 80's. Two flowsheets were developed, the 1979 flowsheet [4], which matched the cycle to an advanced High Temperature Gas-cooled Reactor (HTGR) and a 1981 flowsheet [4,5] that was open ended, permitting the cycle to be matched to a number of thermal sources.

Deterministic global optimization of process flowsheets in ...

Deterministic global methods for flowsheet optimization have almost exclusively relied on an equation-oriented formulation where all model variables are controlled by the optimizer and all model equations are considered as equality constraints, which results in very large optimization problems. A possible alternative is a reduced-space formulation similar to the sequential …
