Tank Venting

Gas Cleaning › Oleum + SO3 Tank Vents

SO3 / OLEUM TANK VENTS

Oleum and liquid SO3 is stored in tanks and when the tanks are being filled or emptied, there is an increase in vent vapour. Similarly, when loading into or from trucks & wagons there will be a SO3 fugitive vapour. This SO3 vapour...

Gas Cleaning › Tank Cleaning Emissions

TANK CLEANING EMISSIONS

In chemical and petro-chemical plants there are various storage vessels for raw materials and for finished products. When some tanks require to be cleaned, there can be a risk of volatiles and other vapours escaping from the tank and causing unacceptable emissions.

Detergent Sulphonation

Filter › Before Reactor

DETERGENT SULPHONATION / BEFORE THE SULPHONATION REACTOR

SO3 gas is used in a sulphonation reaction process. Fibre filters which are installed before the sulphonation reactor remove very fine oleum mists. The SO3 gas (6-7%) can contain up to 7,000 mg/m³ of oleum mists, and due to the...

Detergent Sulphonation

Filter › After Reactor

DETERGENT SULPHONATION / AFTER THE SULPHONATION REACTOR

SO3 gas is used in a sulphonation reaction process. Fibre filters which are installed after the sulphonation reactor remove up to 4,000 mg/m³ sulphonated hydrocarbon mist.
Due to the high viscosity liquid produced with over sulphonisation, it is recommended (a) to...

Phosphoric Acid

Filter › P205 Food Grade

PHOSPHORIC ACID / P2O5 FILTRATION SYSTEMS
A) FOOD GRADE P2O5 PODUCTION PROCESS

Candle Filters can be used in the dry process (electric furnace) described below; the phosphate rock is sintered or nodulized to facilitate escape of phosphorus vapours in the furnace and to prevent the blowing over of...

Phosphoric Acid

Gas Cleaning › Phosphor Bronze Processing

PHOSPHOR BRONZE PROCESSING – PHOSPHORIC ACID / P2O5 FILTRATION SYSTEMS

Phosphorous is injected into a bath of molten copper, to produce Phosphor Copper metal. There is then a fume produced from the reaction in the bath, which is extracted by a fan to a filter system, before the...

Hydrochloric Acid

Filters › Process/Tank Emissions

HYDROCHLORIC ACID / PROCESS FILTRATION

Hydrochloric Acid can be emitted from many industrial processes, where it is either used in that form, or generated from the process.
HCl will usually be in fine, sub-micron mist form.
The gas comes from the process or vapours are drawn to...

Compressed Gas

Gas Filter › Removal of Oil or Water in Gas Production

COMPRESSED GAS PRODUCTION PLANT

Gas is compressed into bottles for Industrial use.
Gas is compressed as part of an industrial process.
These compressors can entrain water or oil into the gas.
Examples :

Compressed CO2, H2 and CO – after compressing synthesis gas at 4,500 PSIG the...
