Vent Gas Recovery System Processes vent gases from CVD Reactor and STC-TCS Converter The centrotherm SiTec Vent Gas Recovery (VGR) System is specially designed to process vent gases generated from CVD Reactors and STC-TCS Converters during polysilicon production. The VGR separates these gases into three product streams to be reintroduced in different stages of the polysilicon production process: Recovered H2 to be re-used in the deposition and conversion process Recovered HCl to be re-used in the TCS synthesis Mixture of liquid chlorosilanes (TCS, STC) to be further separated by distillation and re-used in the deposition and conversion process The centrotherm SiTec VGR System can be adapted to any production capacity. The VGR System enables a closed-loop polysilicon production and provides highest recovery rates (> 99 %) for all compounds of the vent gas streams by applying ultra-low temperature processes. To prevent contamination during the process and to ensure very high purity of polysilicon, the VGR is specially designed with selected construction materials. In addition, the use of special activated carbon ensures high purification of recovered hydrogen. Fully integrated VGR System package to separate vent gases Highest recovery rates for all mixtures of vent gases (> 99 %) Average power consumption of 1,650 kW (3,100 kW maximum) Optimized design reduces operating costs Low investment costs Guaranteed performance parameters TÜV-proven equipment Manufactured according to customer specified standards Commissioning, supervision and start-up by experienced centrotherm SiTec team Laatst gewijzigd door E.

Nu wordt het al wat interessanter:
Ingot Furnace Grows ingots by vertical gradient directional solidification of silicon melt The centrotherm SiTec Ingot Furnace is a key equipment for photovoltaic silicon ingot and wafer facilities. After melting the polysilicon chunks, the furnace grows silicon ingots by vertical gradient directional solidification. The process consists of heating, melting, growing, annealing and cooling stages. Process temperature varies up to 1,550 ºC and process pressure ranges from 0.1 to 600 mbar. The furnace contains a graphite hot zone located in a stainless steel vacuum chamber supported by a base frame. The hot zone contains three independent active thermal elements – side resistive heater, bottom resistive heater and bottom active cooling unit. The hot zone is designed in modular structure and optimized for Gen5 ingots and 450 kg basic charge weight. The furnace has integrated water cooling, argon flow, vacuum pump, power supply, temperature monitoring and fully automated process control systems. The base frame is equipped with an electro-mechanical opening and closing mechanism with an integrated tool for top loading and unloading of the charged crucible. The centrotherm SiTec Ingot Furnace is delivered with a process know-how package. Fully integrated furnace package with power supply and automation system Low total energy consumption: < 10 kWh/kg of ingot Low process cycle time: < 60 h with an uptime > 92 % High productivity: > 60 metric t/a or 7.5 MWp/a Easy process control by PLC: Siemens S7/PCS7 Final safety barrier due to bottom graphite shield Charge weight from 450 kg up to 600 kg Delivered with process know-how package Laatst gewijzigd door E.

Nog ne leuke, "diamonds are forever":
Ingot Squaring Equipment Cuts multi-crystalline ingots into bricks using diamond wire technology The centrotherm SiTec multi-crystalline ingot squaring equipment is key equipment for integrated ingot and wafer facilities. The squaring equipment cuts multi-crystalline ingots [Gen5, Gen6 optional] into bricks using high speed diamond wire technology and cooling water only. The ingot squaring equipment is available in two versions: basic version and advanced version. The basic version consists of one cutting unit. The advanced version consists of two cutting units, buffer and handling system for fully automatic loading, transfer and unloading. No manual handling or gluing of ingot is necessary. A cooling water recycling unit can also be connected to cropping and grinding equipment. The fully automatic process consists of the following steps: Loading of ingot into first diamond wire cutting unit Cutting of ingot into slabs Automatic unloading and transfer of slabs to buffer and then to second diamond wire cutting unit Cutting of slabs into bricks Automatic transfer of bricks to brick line conveyor Advantages Fully automatic cutting and handling process High cutting speed from 10 to 15 mm/min High throughput from 5,7 to 12,5 bricks per hour at 270 mm ingot height Reduced overhead time Automatic clamping, no gluing necessary Modular expandable system Designed to handle Gen5 and Gen6 ingots up to 1,000 kg Cooling water recycling unit optional Zie ook weer niks van verbruik... |

Voor als je beu bent gekeken op koolstof briquetten:
Brick Cropping Equipment Crops multi-crystalline bricks using high-speed diamond wire technology The centrotherm SiTec multi-crystalline brick cropping equipment is a key system for integrated ingot and wafer facilities. The equipment crops multi-crystalline bricks using high speed diamond wire technology and cooling water only. The bricks are loaded manually or automatically by robot system and are automatically clamped. The cut-offs are removed by an appropriate handling system and can be recycled. The multi-crystalline brick cropping equipment cuts at a high speed rate of 20 mm/min, processing two bricks at a time. It is designed for integration into fully automatic production lines. Advantages High cutting speed of 20 mm/min with advanced diamond wire technology Parallel processing of 2 bricks High throughput of 5 bricks/hour [> 100 MWp] Small footprint Very short downtime due to fast exchange of diamond wire Automatic clamping technology Automatic handling of cut-offs Cooling water recycling unit can be connected to centrotherm SiTec fully automatic ingot squaring equipment verbruik? |

Ik denk dat de energievretende toestellen nu wel grotendeels gepasserd zullen zijn. Aanmaken van panelen is meer kwestie van knutselen dan van braden en stoven.
En nu maar beginnen rekenen... |

Maar da's dan nog een positieve situatie. 't Schijnt dat windmolens meer energie kosten om ze te bouwen en draaiende te houden, dan ze in feite opleveren aan energie, lol. Laatst gewijzigd door E. Migrant : 22 december 2011 om 22:13. |

http://en.wikipedia.org/wiki/Silane Nu : uw energie zal volgens mij vooral gaan naar hydrolyse van water om waterstof te produceren, en de goedkoopste waterstof komt gewoon uit een steam reforming van methaan (zal wel geen probleem zijn om te vinden in de woestijn) Dan het zuiveren van silaan, dat is ook iets waar energie zal in kruipen http://www.semi.org/en/IndustrySegme...erials/p044005 Timminco, whose stock has climbed to over 30, up from 70 cents last year, has claimed to have developed a low cost high volume method for creating solar cell grade silicon directly from metallurgical grade silicon. Their process reportedly can be carried out on 5-to-10 ton batches of molten silicon. In response to industry skepticism, the company hired Photon Consulting for a report on their metallurgical silicon production processes. “Operations and processes have potential for massive growth and, possibly, for reshaping the silicon industry”, declared Michael Rogol Managing Director of Photon Consulting. “The (Timminco) equipment is very impressive, very low-cost, beyond poly-scale. In interviews, several customers have reported cell efficiencies above 14% and some above 15% utilizing 100% (unblended) solar grade silicon from Bécancour.” http://en.wikipedia.org/wiki/Polycrystalline_silicon Upgraded metallurgical-grade (UMG) silicon (also known as UMG-Si) solar cell is being produced as a low cost alternative to polysilicon created by the Siemens process. UMG greatly reduces impurities in a variety of ways that require less equipment and energy than the Siemens process.[6] UMG is about 99% pure which is three or more orders of magnitude less pure and about 10 times less expensive than polysilicon ($1.70 to $3.20 per kg from 2005 to 2008 compared to $40 to $400 per kg for polysilicon). It has the potential to provide nearly-as-good solar cell efficiency at 1/5 the capital expenditure, half the energy requirements, and less than $15/kg.[7] |
