生物乙醇工業

從農作物(原料)生產生物乙醇的製程,大致分為以下幾個步驟:培養發酵蒸餾脫水儲存和裝載。首先,將原料放入到制備罐中,在這裡用溫水稀釋。然後,將其放入發酵罐中,將糖漿和酵母混合拌入原料,以發酵原料中的糖。將發酵的糊狀物移至調節塔中以增加乙醇濃度,之後移至蒸餾塔中,其中乙醇含量增加至體積的95%。進入脫水流程除水,使乙醇含量至少達到99.5%(體積百分比),以便乙醇作為燃料添加劑使用。

  • Yokogawa Brazil completed the commissioning of these systems ahead of schedule and the production of green polymer was started just one week later
摘要:

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).

摘要:

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.

摘要:

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.

摘要:

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. 

摘要:

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.

摘要:

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.

摘要:

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.
