This paper describes characteristics of combining the acid making system with blast furnace gas and acidmaking system with converter gas into one (i.e. the gases from blast furnace and converter flow together into gas mixing drum for making acid) and economic benefit and environmental protection benefit achieved by successful adoption of a new equipment - petrin - type heat exchanger.
This paper reviewed the application and effect of membrane technology for oxygen enriched air in production(e.g.gas making,acid making,oxidation reaction),medical treatment and environmental protection.
The article mainly introduces applications and process characterisitic of the technology that mercury-removal by chlorination in making acid in Zhuzhou smelter.
The method is based on the extraction of a Mo(V)-ferron (7-iodo-8-hydroxyquinoline-5-sulphonic acid) complex into trioctylamine-chloroform in a sulphuric acid medium using ascorbic acid as a reductant.
Key parameters (pyrrole, aniline, dopant and sulphuric acid concentrations and deposition potential) influencing the coating's mechanical stability and surface homogeneity were optimised and thermostability of the coating was investigated.
Corrosion resistant iron-titanium alloys have also been developed, which may find use in the hardware of phosphoric acid making plants and other equipment.
The proportion of vaccenic acid in the 18∶1 fraction was 60, 50, 20, and 25% for phosphatidylethanolamine, phosphatidylcholine, triglycerides, and cholesteryl esters, respectively, with oleic acid making up the balance.
