• CYLINDRICAL CONTINUOUS PAN (CCVP) The Tongaat Hulett Cylindrical Continuous Vacuum Pan (CCVP) 3 Cylindrical Continuous Pan Presentation
CYLINDRICAL CONTINUOUS PAN (CCVP) A new continuous pan has been developed by Tongaat Hulet in 2008. This new patented design consist of two stacked calandrias stacked inside a cylindrical vessel . Three new CCVP has been installed in Mozambique in year 2008-2009 consist of - 1 set of A pan 120 m3 - 2 set of A,B pan 100 m3 4 Cylindrical Continuous Pan Presentation
CYLINDRICAL CONTINUOUS PAN (CCVP) ➢ Cylindrical vessel ➢ Two floating calandrias ➢ Common vapor space ➢ Top and bottom each six compartments ➢ Each calandria can be boiled independently ➢ Massecuite flow similar to horizontal CVP 5 Cylindrical Continuous Pan Presentation

CYLINDRICAL CONTINUOUS PAN (CCVP) 14 January 2016 Sutech Group Presentation
CYLINDRICAL CONTINUOUS PAN (CCVP) New continuous pan technology More steam saving in pan boiling Can be installed in existing batch pan position Smaller footprint than horizontal pan Design can accommodate: ➢ Two separate massecuite grades in one pan ➢ Use of different grades of vapor in a single pan ➢ On-the-run boilout of pan. Improved circulation characteristics 15 Cylindrical Continuous Pan Presentation
• ROTARY LIME KILN Rotary Lime Kiln By SUTECH ENGINEERING CO., LTD. 16 Rotary Lime Kiln Presentation
ROTARY LIME KILN ➢ The wet cake (Calcium carbonate cake ) from sugar refinery is the solid waste which need to dispose in the specific area under the law/regulation of each country. ➢ The composition of wet cake consist of Calcium carbonate ( 65-70 %), water ( 30- 35 % ), organic matters, etc. ➢ SUTECH Rotary lime kiln is mainly used for “Calcining” the wet cake from sugar refinery to produce calcium oxide and reuse in Liming of Carbonation system. ➢ Wet cake is calcined in rotary kiln at temperature 900 to 1,200 degree C. water vapor(H2O) and Carbon Dioxide (CO2) will be released from kiln. 17 Rotary Lime Kiln Presentation
ROTARY LIME KILN ➢ SUTECH’s first unit of “Rotary Lime Kiln” is installing in sugar refinery 3,000 TRD in Bangladesh. CaCO 3(s) . H2O (l) CaO (s) + CO 2(g) + H 2 O (g) 18 Rotary Lime Kiln Presentation

• LACTIC ACID Study of Lactic Acid Production from Cane Molasses By SUTECH ENGINEERING CO., LTD. SURANAREE UNIVERSITY OF TECHNOLOGY 24 Lactic Acid Presentation
LACTIC ACID ➢ Lactic acid (CH 3 CH(OH)COOH) is an organic acid that can be produced by fermentative or chemical synthesis. The production by fermentation process has attracted interest due to its advantages, lower cost compared with chemical synthesis. 25 Lactic Acid Presentation
LACTIC ACID ➢ There are many cheap and renewable raw materials used for lactic acid production, such as - raw sugar molasses, - cassava, wheat ,corn,potato, rice - lignocelluloses - and others. 26 Lactic Acid Presentation
FEED STOCK ➢ Lactic acid is widely used in the food preservative, cosmetic, pharmaceutical and biodegradable plastic. ➢ Biodegradable plastic ➢ Cosmetic ➢ Pharmaceutical 27 January 2016 Sutech Group Presentation

LACTIC ACID “ PRODUCTION STUDY ” FROM CANE MOLASSE ➢ The study of Lactic acid production from cane molasses in laboratory is done by Suranaree University of technology in Thailand. The study consist of bacteria screening, fermentation & HPLC analysis. The study will be finished in 2019 and will continue with scale-up project with Sutech in year 2020 to develop the equipment and preliminary engineering design parameters for fermentation and purification. 31 Lactic Acid Presentation
