Commercial concentrated sulfuric acid (66° Baume) is usually used for cooling water pH control. When fed neat, it is nearly twice as dense as water and drops to the bottom of the cooling tower basin. This can damage basin concrete and cause poor pH control. For this reason, the acid should be well mixed with water prior to entering the basin.

Boilers In the sulfuric acid plants, a large amount of heat is generated in the sulfur combustion furnace for SO2 production and it is required to cool these gases. This cooling is done in a boiler system in which steam is produced as a by-product, which makes the sulfuric acid plants very efficient energetically.
into boiler feed water Steam generating boilers are com-monly used in sulfuric acid plants, for process gas cooling, waste heat recovery and steam usage at various locations. The steam—typically in the 450 to 900 psig range—drives turbines, and upon pres-sure reduction meets other heating needs in the plant. Upon extracting the useful
Table 3.16 Steam production from waste heat boiler Figure 2.1 Capital cost vs capacity relationship for Sulfuric acid plants It is also used as a gener al dehydrating agent in it s .
Steam Traps, Valves and Level Gauges Controllers and Instruments Acid Plant. Ensure a safe, reliable, and profitable process. The production of sulphuric acid from elemental sulphur is a delicate process that must be completed in a safe manner.
Boilers installed in sulphur burning plants should have a bypass valve and a valve located at the gas outlet. The outlet valve is used during plant preheating to force hot combustion gases through the open bypass directly to the converter beds.
Sulphuric Acid Plant Specifications . Google Search . Steam Systems - Piping Systems October 21, 2002. ASME B16.34 Valves-Flanged, Threaded, and Welding End. Steam Line Sizing. It is important that the steam generated in the boiler arrives at the end user at the desired pressure. Steam lines should be sized to ensure that the line losses
Nov 01, 2004 · Treatment of boiler feed water is required for preventing excessive heat transfer equipment fouling and erosion of turbine blades. Solution. Technological advances in membrane filtration systems create an opportunity for industrial boilers and steam power plants to treat boiler feed water streams to meet stricter system performance.
Oct 26, 2015 · FB-1 CECEBE Furnace By-Pass System The conventional system for sulfur burning in a sulfuric acid plant consists of a sulfur furnace, a waste heat boiler and a jug valve in the by-pass line around the waste heat boiler. In the sulfur furnace, liquid sulfur is burned in dry air to produce an SO2 gas.
Enmax Engineerind (India) Pvt Ltd an ISO 9001:2008 conmpany, located in Hyderabad, India are in to design, manufacture, supply of fired boilers, waste heat recovery system (Waste Heat Boiler, super heater, economizer, heat exchangers, etc.) for sulphuric acid plants.
Valves in sophisticated materials such as titanium, monel, and hastelloy are supplied for corrosive acids, aromatic anhydride, sulphuric acid, ethylene dichloride, and others. We can offer a complete line for almost all of these plants, including bellows seal and cryogenic valves in globe, gate, ball, and triple-offset variations, all from one

AVT (Advanced Valve Technologies) is pleased to announce the launch of its new Sulphuric Acid Valve, able to handle an unusually wide range of sulphuric acid duties. The new ANSI150 and PN16 valves, based on a proprietary Novolac material technology, will accept duties in concentrations from 1% to 99%, working at temperatures up to 190°F (90°C).
The main parameters that affect a steam boiler's efficiency are boiler load, combustion air, stack gas temperature, radiant heat loss, and acid dew point. In this article, natural gas fired conventional steam boilers are evaluated and potential savings are determined in the power plant of Tüpraş İzmir refinery.

Steam systems are most commonly associated with sulphur burning sulphuric acid plants, however, acid regeneration plants have steam systems and some metallurgical acid plants. When the process generates waste heat, the generation of steam is the simplest way to put the energy to use either for process uses or for the generation of electrical power.
Turnkey Solutions as well with Trim, Piping, Deaerator, Valves, Fiels Instruments, Electric etc. Sulphuric Acid production based on Sulphur combustion is an exothermic reaction generating a considerable amount of heat which can be recovered of heat which can be recovered as high-pressure steam which can be converted into electricity.
There are described a process and a plant for producing sulfuric acid by catalytic oxidation of SO 2 to SO 3 and subsequent absorption of SO 3 in sulfuric acid, wherein the SO 3 is introduced into a first absorption stage and absorbed there in concentrated sulfuric acid, wherein the sulfuric acid having a higher concentration due to the absorption is passed through a heat exchanger and cooled
Sulphuric acid recovery from sulphurous waste streams. The WSA process is a catalytic system for producing concentrated sulphuric acid from any sulphur-containing offgas, without the use of chemicals. Sulphur recovery has for many years been an integral part of a refinery or a petrochemical plant, and is in most cases based on production of
