Green3Power International and Togo Technologies are well into process of developing a 144 MW, 4,800 tonnes/day (Tpd) Gasification Facility in Kakamega, Kenya. The Gasification Facility will receive approximately 4,800 Tpd of municipal solid waste, hazardous medical waste, industrial waste as well as approximately 10 tonnes/day of used tires, and generate a nameplate capacity of more than 144 MW, with available power of 120 MW, and a minimum average of 108 MW to the Grid 24 hrs/day, 365 days/yr. The Gasification Facility includes a Sorting Facility to remove recyclables and heavy metals, an in-line jacketed Waste Dryer, a Gasifier, a Cyclone to remove particulate matter from the synthesis gas, a Slagging Unit, a high efficiency, a high temperature and high pressure HRSG Boiler, a four-stage Steam Turbine/Generator, and a highly effective flue gas treatment system. When in full operation, the new ~ $600 million power plant will deliver an average of 120 MW of electrical energy to the Grid, while earning revenues of more than $260 million annually. The power plant will feature an effective flue gas clean up train to ensure that regulated emissions are far below the concentrations allowed under both Kenyan and U.S. Federal air quality standards. The fluidized bed gasifiers to be used at the new facility are of the type shown above and have been in waste to energy service for more than 33 years.
The waste is sorted to remove recyclables such as metal and glass to be sold to recycling companies, as well as unacceptable waste such as e-waste, dirt, and rocks. Acceptable materials are fed through a shredder to reduce the particle size prior to entering the dryers which reduce the water content.
From the dryer, waste is fed into the Rotary Kiln Gasifiers which convert the solid waste into synthesis gas and ash at a temperature of 1,000 deg. C. The Synthesis gas is combusted in a reducing environment to prevent NO2 formation, and then processed through an HRSG Boiler to produce high temperature and pressure steam. The Steam is fed to a high efficiency steam turbine to generate clean, green, renewable electric energy. The flue gas is processed through a Cyclone to remove particulate matter, an Acid Gas Removal Unit to remove HCl, H2S, and HNO3, an Electrostatic Precipitator to remove sub 2.5-micron particulate matter, a Bag House with carbon injection to remove particulate matter, heavy metals, and organics, and is then discharged out the stack at a temperature of 140 deg C, which prevents condensation. Therefore, there is nothing visibly discharged from the stack. The constituent concentrations in the stack are more than 1,000 times lower than EU and USEPA Air Quality Standards, some of the most stringent in the world. The project includes the collection of waste. A total of 267 compaction trucks and 10 crane trucks will operate 7 days per week to collect and transport waste to the sorting facility.
The project includes the purchase of 8,638 1.1 liter bins, 1,728 3.0 cu m bins, and 1,152 5.0 cu m bins. The trucks and supervision vehicles will be fitted with GPS and communication systems to track the progress of the collection vehicles at all times during the collection and transport process. In addition, 300 mobile street sweepers will be employed to sweep and clean the streets in Kakamega and the surrounding areas. When in full operation the power plant will directly employ approximately 2,350 people and indirectly create another 4,000 jobs. It also plays a crucial role in the USD $2 billion Mwale Medical and Technology City (MMTC) as the main source of power and proper waste disposal.
USD $2 billion Mwale Medical and Technology City (MMTC)
The Green3Power Gasification facility is an important component of the overall MMTC facility and community, providing much needed waste service, and power.
MMTC is the largest single private development in Kenya and includes the 144 MW Gasification Power Plant, a 5,000 bed hospital with 8,000 staff treating 12,000 patients per day, two world class shopping malls, a 1,500 room 5-star golf resort, an airstrip, and over 4,000 new homes. As of July 2016, over 90,000 square feet of upscale residential homes and apartments have been constructed, furnished and occupied. Hamptons Mall, a multi-billion shilling residential and shopping complex and the first of the 2 shopping malls at MMTC, (see photo below or read more at www.hamptonsmall.com) is complete and fully occupied. A strong international community has made Hamptons Mall its home, including the UK based Barclays Bank, the American restaurant Hamptons Café, known for upscale service, and Mwal-mart, a supermarket stocked full with thousands of American brand-name products. Additionally, the foundations of the 1,500 room 5-star golf resort and 5,000 bed hospital are fully underway; with the construction sites operating into the night with the aid of over 600 hundred solar and grid based lights transforming night into day.
Can the good people of Kakamega confirm this mega project please.
