• calcium oxide (15) or calcium hydroxide may be added to sugar process liquid (4) to raise the pH allowing certain dissolved materials to come out of solution as solids, flocculent, or floes.
• Calcium oxide is typically obtained through calcination of limestone a process in which the limestone is heated in a kiln in the presence of oxygen until carbon dioxide is released resulting in calcium oxide. Calcination can be expensive because it requires the purchase of a kiln, limestone, and fuel, such as gas, oil, coal, coke, or the like, which is combusted to raise the temperature of the kiln sufficiently to release carbon dioxide from the limestone.
• Ancillary equipment to transport the limestone and the fuel to the kiln and to remove the resulting calcium oxide from the kiln must also be provided along with equipment to scrub certain kiln gases and particles from the kiln air exhausted during calcination of the limestone.
• calcium oxide generated by calcination must be converted to calcium hydroxide for use in conventional sugar process systems. Again this involves the purchase of equipment to reduce the calcium oxide to suitably sized particles and to mix these particles with water to generate calcium hydroxide.

• the amount of recalcined lime required to neutralize the same amount of hydronium ion in juice may be correspondingly higher.
• the carbon dioxide content of spent lime can be much higher than limestone.
• Another significant problem with conventional sugar process systems may be an incremental decrease in sugar process system throughput corresponding with an incremental increase in the amount of lime (15) used in processing sugar process liquid (4).
• One aspect of this problem may be that there is a limit to the amount of or rate at which lime (15) can be produced or provided to sugar process steps.
• lime stone must be calcined to produce calcium oxide (15) prior to its use as a base in sugar process systems.
• the amount of lime (15) produced may be limited in by availability of limestone, kiln capacity, fuel availability, or the like.
• the rate at which lime (15) can be made available to the sugar process system may vary based on the size, kind, or amount of the lime generation equipment, available labor, or the like.
• Another aspect of this problem can be that the amount of lime (15) used in the sugar process system may proportionately reduce volume available for sugar process liquid (4) in the sugar process system. Increased use of base, such as lime (15), may also require the use of larger containment areas, conduits, or the like to maintain throughput of the same volume of juice.
• Another significant problem with conventional sugar process systems can be limesalts in sugar process liquid (4) which are not precipitated during the steps of preliming (123), mainliming (17), and carbonation (18)(19), but none-the-less, must be removed from sugar process liquid (4) prior to evaporation of water from "thin juice” to prevent or reduce scale formation in the evaporator.

• the process of removing scale from the surfaces of equipment can be expensive, including, but not limited to, costs due to production slowdowns and efficiency losses, or the reduction in the effective life of equipment.
• sugar process liquids (4) can be passed through an anion exchanger (34) which binds calcium ion to anion exchange resin in exchange for the release of two sodium ions which are transferred to the sugar process liquids (4) (certain conventional process systems do not remove limesalts prior to evaporation).
• anion exchanger (34) which binds calcium ion to anion exchange resin in exchange for the release of two sodium ions which are transferred to the sugar process liquids (4) (certain conventional process systems do not remove limesalts prior to evaporation).

• the spent regenerant (35) primarily made up of calcium ion and hydroxide ion in solution(when sodium hydroxide in solution is utilized as a regenerate) has a high pH and can be recycled prelimer (14) to supplement to the milk of lime (18). This can be a benefit by reducing the amount of milk of lime (18) needed to increase pH of the sugar process liquid (4) in the prelimer (14) to achieve a pH in the range of 11.5 to 11.8.
• limesalts increase the amount of spent regenerant (35) produced also increases and can cause problems in balancing the prelimer (14) to operate consistently. Shifts in alkalinity and pH in the prelimer (14) can result in poor removal of non-sucrose materials and higher limesalts which in turn requires more frequent regeneration of the anion exchanger. All of which add cost to the production of sugar.

• RBU reference base units
• the "white centrifugal wash” (32) must be adjusted to bring the color of the "white pan” sugar crystals (33) from 43 RBU to 40 RBU. Adjustment of the centrifugal wash (32) to reduce color also reduces the amount of sugar (33) produced by about 0.65 tons/hour.
• Another significant problem with conventional sugar processing systems may be low purity of sugar process liquids (4) expressed as a percent ratio of sugar to total dry solids of sugar process liquid (4).
• concentration of total dry solids in sugar process liquid (4) including any of the above-described materials or other materials, relative to the amount of sucrose in the sugar process liquid (4), the less desirable the sugar process liquid (4).
• any decrease in the total dry solids relative to sucrose in the sugar process liquid (4) yields a comparatively better juice for subsequent purification.
• Soluble non-sucrose materials in sugar process liquid (4) can interfere with subsequent processing or purification steps or adversely impact the quality or quantity of the resulting sugar or other products produced. It has been estimated that on average each pound of soluble non-sucrose substances reduces the quantity of sugar produced by one and one-half pounds. As such, it may be desirable to have all or a portion of these soluble non-sucrose substances separated from or removed from the sugar process liquids (4). For example, in the sugar process system above described, a thin juice color of about 2,500 RBU with a "thin juice" purity of about 92.00 can produce about 57 tons of white sugar per hour at 30 RBU. If "thin juice" purity can be increased to about 92.40 white sugar yield can be increased by 0.54 tons per hour.
