HYPOCHLORITE SWEETENING

A petroleum refinery process to oxidize gasoline mercaptans by agitation with an aqueous, alkaline hypochlorite solution.

HYDROTHERMAL CRYSTAL GROWTH

Formation of simple crystals of quartz at elevated temperatures and pressures in an autoclave with an alkaline solution.

HOLOPULPING PROCESS

A process for making paper pulp by alkaline oxidation of extremely thin wood chips at low temperature and pressure and then solubilization of the lignin fraction.

DE-ALKALIZER

An apparatus or device used to remove the alkaline carbonate and bicarbonate ions from a water supply.

ACID CLEANING

The process of cleaning the interior surfaces of steam-generating units by filling the unit with a dilute acid accompanied by an inhibitor to prevent corrosion and by subsequently draining, washing, and neutralizing the acid by a further wash of alkaline water.

BOILING OUT

The boiling of a highly alkaline water in boiler pressure parts for the removal of oils, greases, etc. prior to normal operation or after major repairs.

ALKALINE (SULFATE OR KRAFT) PROCESS

A chemical pulping process that uses an alkaline cooking liquor, caustic soda, plus heat to break the bonds in wood between the cellulose and the wood fibres.

SULFATE PROCESS

BATTERY

An electrochemical device that stores electric current, often specialised as a cranking battery (for starting the engine) and house battery (for powering lighting and utilities), the latter often being the deep cycle type (capable of repeated full discharge and recharge with minimal degradation). The traditional wet cell lead acid battery (with dilute sulphuric acid as the electrolyte) is being increasing replaced by the newer maintenance free gel cell batteries. Technological advances from lead acid batteries include alkaline (ni-cad) and lithium electrolyte based batteries.

CAUSALITY

1. In classical mechanics, the principle that the specification of the dynamical variables of a system at a given time, and of the external forces acting on the system, completely determines the values of dynamical variables at causticization. 2. A process for converting an alkaline carbonate into lime.
