详细介绍
生物乙醇工艺
从农作物(原料)生产生物乙醇的过程,大致分为以下几个步骤:培养、发酵、蒸馏、脱水、储存和装载。首先,将原料放入到制备罐中,在这里用温水稀释。然后,将其放入发酵罐中,将糖浆和酵母混合拌入原料,以发酵原料中的糖。将发酵的糊状物移至调节塔中以增加乙醇浓度,之后移至蒸馏塔中,其中乙醇含量增加至体积的95%。进入脱水流程除水,使乙醇含量至少达到99.5%(体积百分比),以便乙醇作为燃料添加剂使用。
流程:
培养发酵
- 酵母罐/发酵罐温度控制
- 发酵管理
- 清洗管理
- 发酵液含糖量测定
蒸馏和脱水
蒸馏
- 输入流量控制
- 排放流量控制
- 回流流量控制
- 罐水平控制
- 底部液位控制
- 塔温度控制
脱水

- Batch processes that require careful automated control for maximum efficiency and product quality
- CENTUM VP Batch package improves productivity.
- Reduction of operator workload and safe operation.
- Yokogawa provides STARDOM and FAST/TOOLS for biomass pilot plant.
- FAST/TOOLS is an "all in one" SCADA solution that functionsa a data historian.
This introduces a system that uses Ethernet communications to acquire measured values, target values, and control output values from a controller installed on site into a PLC at high speed (ten units' worth within one second).
The worlds of process automation and production management have been converging for some time. What once used to be islands of automation and production management functionality connected through highly proprietary integration schemes that were costly to maintain have developed into integrated platforms that provide seamless data exchange between the world of automation and the plant floor, the functions of production and operations management, and integration with business level systems.
The automation suppliers that will be successful in the long term will be those that effectively address application or industry specific problems for end users with a value proposition that cannot be ignored. These problems exist throughout the process industries today, and they won't be solved by simply offering a product, but through a combination of hardware, software, services, application expertise, and knowledge.
In ARC's view, customers need a compelling business value proposition to justify investment in any kind of automation. Vigilance and VigilantPlant were created with this in mind. Yokogawa's vision with VigilantPlant is to create an environment where plant personnel and operators are well informed, alert, and ready to take action.
Yokogawa has come a long way in making its message clear to the world of process automation. Last year, the company embarked on a full-scale global marketing campaign to make customers aware of the company's focus on system reliability, security, dependability, and robustness. Dubbed "Vigilance", the campaign created a unified message for the company and greatly helped expand awareness of the Yokogawa brand and corporate philosophy.
Process automation end users are under more pressure than ever to do more with less. The current economic climate means that many automation capital projects are on hold. With capital budgets tighter than ever, users instead focus on operational budgets (where cost cutting is also a key concern), or on automation investments with a very rapid return on investment.
In today's dynamic industrial marketplace, the only constant is change. Raw material costs, energy costs, market demands, environmental and safety regulations, technology, and even the nature of the labor force itself are constantly changing, and not always in predictable directions.
