SILICON-CONTAINING PRODUCT FORMING APPARATUS

According to one embodiment, a silicon-containing product forming apparatus includes a reaction chamber, an emission path, a process liquid tank, a supplier, and a flow path switcher. The emission path emits an emission material from the reaction chamber. The supplier includes a supply line configured to supply a process liquid to the emission path from the process liquid tank, and a byproduct generated by reaction is treated in the emission path by the supplied process liquid. The flow path switcher switches the communication state of the emission path with each of the reaction chamber and the supply line of the supplier.

Purification process

A process is described for removing halogen compounds, particularly chlorine compounds, from a process fluid, comprising the steps of (i) passing a process fluid containing hydrogen halide over a first sorbent to remove hydrogen halide and generate a hydrogen halide depleted process fluid and then, (ii) passing the hydrogen halide depleted process fluid over a second different sorbent to remove organic halide compounds therefrom. A purification system suitable for removing hydrogen halide and organic halide compounds from process fluids is also described.

Abatement system

Venturi Scrubbers are used to separate particulate from a large range of fluids. Many provide additional liquid and/or gas to drive the fluid and aid in the removal of particulate. The present invention provides a liquid ring pump through which the fluid to be treated is first passed and then exhausted, with additional work fluid to a Venturi scrubber such that the particulate can be separated from the exhaust fluid.
