In high concentrations Hydrogen Sulfide can be lethal. It occurs in natural gas, oil, volcanic emissions, and some mineral springs. In oil refining processes its presence is undesirable, and it must be removed. The Clause process is one of the methods used to remove the hydrogene sulphide, and while doing so, recover elementar sulfur.
In pactice this sulfur removal process requires a gas-tight, zero leakage, high temperature and high pressure blower for intermittent duty that must handle toxic gases and must be capable of being brought on line immediately upon demand. To do this the following features on the blower must be provided:
- Double welded casing construction;
Steam jacketed construction can also be used in other thermally critical chemical processes. As to air-tifgt and zero-emission construction, it is used in the following industries:
* Pollution Control
for containment of hazardous organic and inorganic compounds in industrial process plants and other critical applications. Special construction and shaft sealing devices are available for blower service requiring zero or minimal gas leakage into and out of casing.
CBC Canada Co. has a lot of experince with gas-tight and zero-leakage construction on fans and blowers, including: multistage lip shaft seals; Buna-N, Viton and Teflon seals; mechanical shaft seals; special fan housing gasketings; single and double carbon ring seals; hermetically sealed blowers; magnetofluidic and ferrofluidic seals; and packed stuffing boxes with barrier liquids and purgeable seals.
Specific code welding processes and special fan design features are used too - to ensure complete gas tight integrity.
Some special materials and alloys frequently used in gas tight fans, especially for service in hazardous, abrasive, corrosive and high temperature environments, include:
Corten, ASTM A36 Carbon Steel, Hastelloy, Inconel, Stainless Steels of different kinds, Titanium, Monel, Aluminum, Teflon, Rubber LIning. These materials are typical for industrial applications requiring high strength alloys and super alloys too.
Canada Fan Co. is a world wide distributor of industrial process ans OEM fans and blowers, as well as fan components; including high pressure blowers, high temperature fans, spark resistant and explosion proof ventilators, tubeaxial and vaneaxial high pressure ventilators. CBC Canada Co. also does existing fans and blowers repairs, re-build, as well as dynamical wheels balancing.
