General Infromation
Sulphonation Plant for
500 KGS/HR. 98% Sulphuric Acid Based Labsa Plant
A continuous process, skid-mounted plant consisting of day
tanks, storage tanks, flow control and proportioning
arrangement, sulphonation with a dominant bath technology,
complete with built-in heat removal and mixing arrangement. The
plant also contains ageing, dilution and separation sections for
stratification of the product and byproduct spent acid.
The plant is provided with appropriate instrumentation with
alarms /safety interlocks to warn the operator and /or prevent
any malfunction. A control panel allows remote plant operation.
Local and remote display of critical parameters enable ease of
operations and control.
The plant is constructed on a skid platform with built-in
ladders / operating platforms for easy operational and
maintenance access. The skid and plant construction allows quick
at-shop assembly, disassembly and at-site re-assembly as well as
easy relocation of the plant should the need arise.
Capacities available from 250kgs/hr. to 10,000 kgs/hr.
Advantages of
Sulphuric Acid based Sulphonation Plants
- Capital outlay-wise, these plants are considerably
cheaper than the sulphur burning plant.
- Sturdy, easily relocatable plants requiring little
maintenance as compared to the complicated, instrumented
sulphur burning plants which require round the clock
maintenance with skilled personnel both for mechanical
as well as instrument parts.
- Unaffected by sudden power outage. No off-spec
product generation. Sulphur burning plants are extremely
intolerant of any unscheduled shutdown with generation
of substantial qualities of off-spec product, and in
certain circumstances, badly charred product difficult
to blend.
- Better conversion due to very low NDOM (Non-Detergent
Oily Matter) and yet excellent colour of the sulphonated
product (and hence, of the finished detergent)
- Lower operating costs: Sulphur burning plants also
run a mini-sulphuric acid plant in addition to the
sulphonation plant. This requires substantial amount of
energy to drive the main air blower, dry air generation
unit etc.
- Much milder environmental impact. The sulphuric acid
based plant by-product is much sought after for making
super phosphated. Thus, there is no effluent stream. On
the other hand, the sulphur burning plant needs
extensive treatment of the exhaust gases including
scrubbing, electrostatic mist removal etc. All this not
only requires electricity but also leaves several
effluent streams requiring treatment.
- Easy to operate and control with just one operator
per shift as compared to the sulphur burning plants
requiring several skilled personnel per shift.
