Identification of reaction zones in a commercial Sasol-Lurgi fixed bed dry bottom gasifier operating on North Dakota lignite
(Elsevier, 2011)
The Sasol-Lurgi fixed bed dry bottom gasification technology has the biggest market share in the world with 101 gasifiers in operation. To be able to further improve the technology and also to optimise the operating plants, ...
High-glycolytic cancers and their interplay with the body's glucose demand and supply cycle
(Elsevier, 2011)
Many difficult-to-treat solid cancer tumours and metastases have high-glucose uptake, usually under hypoxic conditions. Hypoxic tumours suppress the immune system and are insensitive to traditional chemoradiotherapies. The ...
The design and development of a stented tissue mitral and aortic heart valve replacement for human implantation
(Clinics Cardive, 2012)
A study was conducted into the development of a mitral and aortic heart valve replacement that caters for patients having suffered valve damage due to stenosis or rheumatic fever. The appeal of the valve is that it is ...
Prelimanary application of a new Bolus Insulin model for Type 1 Diabetes
(Mary Ann Liebert, 2011)
Previous work derived a theoretically rigorous bolus insulin model. It was shown that the new model predicts insulin response of subjects without diabetes substantially better than the carbohydrate counting method (CHOcm). ...
Dataset on the carbon dioxide, methane and nitrogen high-pressure sorption properties of South African bituminous coals
(Elsevier, 2019)
The dataset presented in this article supplements the result and information published in the report “The carbon dioxide, methane and nitrogen high-pressure sorption properties of South African bituminous coals” (Okolo et ...
Pressure-drop predictions in a fixed-bed coal gasifier
(Elsevier science, 2011)
In the Sasol Synfuels plant in Secunda, Sasol-Lurgi fixed-bed dry-bottom gasifiers are used for the conversion of low-grade bituminous coals to synthesis gas (syngas). The gasifiers are fed with lump coal having a particle ...
Effectivity of phenol during solvent extraction of a South African bituminous coal under mild conditions
(ACS, 2017)
Solvent extraction of a South African bituminous coal was carried out under mild conditions (<400 °C) with a holding time of 20 min and an initial nitrogen (N2) pressure of 6 MPa. Thermal degradation of coal with phenol ...
Investigation and efficiency analysis: 405 km transmission line with series compensation
(Crown Publications, 2012)
This article presents an investigative case study and efficiency analysis of the 405 km, 420 kV transmission line between Insukamini substation
in Bulawayo, Zimbabwe and the Matimba thermal power station in South Africa ...
Design and heat flow analysis of a commercial energy efficient in-line water heating system
(Emerald, 2014)
In this paper, the authors provide the design, heat flow analysis and pressure analysis of a commercial energy efficient in-line water heating system in South Africa. The designed commercial in-line water heating system ...
Efficiency analysis of a three-phase power transformer
(EE Publishers, 2014)
Metal, chemical, cement, concrete automobile, mining and other industries struggle to increase the efficiency of the energy they use.
Three-phase power transformers play significant role in terms of energy saving, so one ...
