Chemical Balance as a Rheometer for Biological Fluids

Journal of Pharmaceutical Sciences, 1970
Abstract The chemical balance provides a simple, cheap, and readily available method of assessing the consistency of biological fluids such as sputum.Scale reading at an arbitrary time provides a useful empirical parameter that can be employed in routine testing of clinical samples and in the assessment of mucolytic agents.It also correlates well ...

A Chemical Element Balance for the Pasadena Aerosol

Journal of Colloid and Interface Science, 1972
A method has been developed for calculating on a chemical element-by-element basis the contribution of various sources to the aerosol of a polluted atmosphere. Four major sources have been considered and their relative contributions estimated by employing certain trace elements characteristic of each source; sodium, aluminum, lead, and vanadium were ...

STEAM BALANCE OPTIMIZATION IN CHEMICAL PLANT

IFAC Proceedings Volumes, 1994
Abstract Mitsubishi Kasei Mizushima Plant accomplished steam balance optimization in power plant providing the required steam and electricity to the various processes at their maximum efficiency in real time using simulator and expert system. This paper describes the status of the project and the results obtained so far.

Chemical Mass Balance

1995
Various applications of the chemical mass balance technique to study source-receptor relationships for air pollutants deposited on particles are described. Examples of the technique used to study the physico-chemical behavior of trace elements during combustion of fossil fuels in electric power plants and wastes in waste incinerators are presented on ...

Mass Balance of Production Chemicals

Proceedings of SPE International Conference on Health, Safety and Environment in Oil and Gas Exploration and Production, 2002
Abstract Estimates of the amount of discharged production chemicals are most often calculated using octanol/water partition coefficients. This is due to the lack of any better methods to predict how much of the chemicals is water soluble and would thus follow with the produced water to sea.

On Some Chemical Balance Weighing Designs

Australian Journal of Statistics, 1971
SummaryThe present paper deals with certain chemical balance weighing designs. The incidence matrices of BIB designs and balanced ternary designs have been used to construct these designs. Conditions have been obtained to make some of these designs “optimum”.

Quick-acting chemical balance

Journal of Scientific Instruments, 1959
The balance described is particularly well suited for use in an analytical laboratory in which repetitive weighings are made to an accuracy of one part in 5000. It is characterized by rapidity of operation, and robustness of suspension. Its regular use should enble substantial savings in time and labour to be made. The beam is balanced by an electronic

Magnetic Operation of Chemical Balances

Review of Scientific Instruments, 1939
Two types of balance are described for measuring small weights by application of a magnetic force in place of the usual system of calibrated weights. One method is applied to an analytic balance, the other to a vacuum balance.

Material balances for chemical reactors

1997
This chapter discusses how material balances should be performed for the three fundamental reactor types used in reaction engineering. These include the plug flow reactor (PFR), the continuous stirred tank reactor (CSTR), and the perfectly mixed batch reactor.
