Your One-Stop Partner for Premium Chemicals, Lab Instruments & Process Solutions.
Khan Associates supplies process chemicals to sugar mills, sugar refineries and distilleries across Pakistan. We have served this industry since 1994, through more than thirty crushing seasons, and the range on this page reflects what mills actually order: mill sanitation biocides, juice flocculants, antiscalants, descaling aids, pan boiling aids, decolourizers, flotation aids and filter media, alongside antifoams and preservatives for distillery operations.
Sugar processing is a sequence of separations, and chemistry supports every one of them. A biocide at the milling tandem protects sucrose that has already been paid for. A flocculant at the clarifier decides juice clarity and mud settling rate. An antiscalant on the evaporators decides steam consumption. A penetration aid decides how long the plant stays down for cleaning. Getting these choices right compounds across a season.
We are an importer, stockist and authorized distributor, not a repacker. Products are supplied with technical data sheets and batch documentation, backed by application support from our technical team and by our own quality control laboratory.
Most sugar mills in Pakistan produce plantation white sugar through the double sulphitation route: mixed juice is heated, limed and treated with sulphur dioxide, heated again above boiling point, then settled in a clarifier before evaporation and pan boiling. Refineries add decolourisation and filtration stages on top.
That process creates a predictable set of chemical requirements:
The products below are organised the way a mill actually runs, not alphabetically.
Complete chemical solutions covering sanitation, clarification, scale control, and refining workflows.
Mill Sanitation and Microbial ControlCut cane arrives carrying bacteria that convert sucrose into dextran and other polysaccharides. The losses are direct, sugar that never reaches the pan, and indirect, through higher juice viscosity, slower clarification, filter blinding, slime formation and crystallisation problems. Cut-to-crush delays make it worse, which is why mill sanitation matters most in exactly the conditions Pakistani mills face during peak arrivals. Biocide SDD is a broad-spectrum microbiocide active against bacteria, fungi and algae. Controlling microbial growth and slime at the milling tandem and other stations protects sucrose that would otherwise be lost before clarification. Dosing points and rates should be set for your tandem and cane condition rather than copied from another mill. | Juice Clarification and FlocculationClarification determines the quality of everything after it. A flocculant is dosed just ahead of the clarifier so that suspended solids and precipitated non-sugars form settleable flocs, producing faster mud settling, shorter thickening time and clearer juice. Accofloc A 2125 is a sugar-grade juice flocculant developed for rapid clarification of both low- and high-brix cane juice. ACCOFLOC is the emulsion polymer flocculant series from MT AquaPolymer, Inc. of Japan, for whom Khan Associates is the authorized MT AquaPolymer distributor in Pakistan. Because flocculant performance depends on the specific juice, we select grade and dose through jar testing on your own samples rather than by catalogue. |
Foam and Evaporator Scale ControlAntifoam AD 50 controls foaming through the process. Foam wastes vessel capacity, interferes with level control and causes carry-over losses. Kemcide AP is a threshold-type antiscalant that retards scale formation in evaporators. Reduced scaling translates into steam economy and longer runs between cleaning stops. | Descaling, Cleaning and Acid ProtectionKafzol FN is a penetration aid. It helps caustic or acid penetrate through the scale thickness and reach behind the deposit, softening and loosening it. That reduces the caustic soda, acid, cleaning brushes and labour consumed per clean. Kafzol R is an acid inhibitor for use in hydrochloric, sulphuric or sulphamic acid pickling systems, giving inhibition against corrosive attack on base metal during cleaning. Aggressive cleaning without inhibition buys a clean surface at the cost of tube life. |
Pan Boiling and DecolourisationKafzol WN is a visc aid, also described as a pan boiling aid, used for the processing of intermediate and after-product strikes. Purefloc and Arquad are used as decolourizing agents in refining. They react with colour-forming impurities to form coagulated particles that can be separated, leaving a clear fine liquor. Arquad is a registered trademark of Nouryon for quaternary ammonium compounds; Khan Associates is the authorized Nouryon distributor in Pakistan. | Flotation and Filtration MediaAccofloc A 110 is developed for rapid flotation of scum in the sugar refining process, producing clear fine liquor. Kem Filter Media C is a coconut-based carbon media used for filtration of sugar liquor at the refinery, polishing the liquor after decolourisation. |
Distilleries attached to sugar mills ferment molasses, and their chemical requirements are shaped by a different constraint: the process depends on living yeast. Anything dosed into a fermenter has to control the problem without damaging the organism doing the work.
Three requirements come up consistently: keeping foam under control in the fermenters, protecting stored molasses between and during seasons, and keeping distillation columns free of scale.
Process chemicals are only part of what a sugar mill consumes. The same site runs bagasse-fired boilers, cooling systems, an effluent treatment plant and a process laboratory, and Khan Associates supplies all of them.
A sugar mill typically uses mill sanitation biocides at the milling tandem, flocculants for juice clarification, antifoams for foam control, antiscalants for evaporators, penetration aids and acid inhibitors for descaling, and pan boiling aids for crystallisation. Refineries add decolourizers, flotation aids and filter media. Khan Associates supplies all of these categories in Pakistan.
Clarification in a plantation white sugar mill uses lime and sulphur dioxide, with phosphoric acid where juice phosphate is insufficient, and a polymer flocculant dosed ahead of the clarifier to accelerate mud settling and improve juice clarity. We supply Accofloc A 2125, a sugar-grade juice flocculant for both low- and high-brix cane juice.
A flocculant is a high molecular weight polymer that binds fine suspended solids and precipitated non-sugars into larger flocs which settle quickly. Without one, mud settles slowly, juice clarity suffers and the filter station is overloaded. Grade selection depends on your juice, which is why we jar test on your samples.
An antiscalant retards scale formation on heat transfer surfaces, principally the evaporators. Scale reduces heat transfer, so steam consumption rises and crushing capacity falls. Threshold-type antiscalants such as Kemcide AP interfere with scale crystal growth, improving steam economy and extending the interval between cleaning stops.
Distilleries fermenting molasses use antifoams in the fermenters, preservatives for stored molasses, and antiscalants for the distillation columns. Khan Associates supplies Antifoam AD 50, Polymer C40 and Kemcide AP for these applications.
