Process Design

drawings can join customers' engineering design projects and use professional drawing software such as Auto CAD, SmartPlant P & ID, COMOS P & ID to assist customers in drawing and modifying PFD and PID drawings. Using process calculation software such as Aspen Plus, Aspen EDR and FRI, assist customers to complete material balance and energy balance, equipment design and calculation, pipeline hydraulics calculation, etc.; Assist customers to complete the preparation of equipment list, pipeline list, instrument condition table, etc.

Accessory Services:

◆ Professional software consulting: SmartPlant P & ID, Aspen Plus, etc.

◆ Training support: SmartPlant P & ID, Aspen Plus, etc

-Nanjing-SP P & ID

in the actual production and operation of the factory, the maintenance and transformation of the production site is in the process of continuous progress, and at the same time, the annual overhaul will involve the continuous update and increase of the P & ID diagram. At the same time, new devices are also increasing, which need to reflect the field information to the P & ID intelligent system in time, so that the system is consistent with the field information.

, in 2010, the customer put forward a demand for adding and updating nearly 2000 drawings from 6 factories, and at the same time, it is necessary to improve the relevant process equipment information and pipeline attributes. After nearly five months of hard work, the finished product documents including equipment data sheet, pipeline table, online instrument list, valve list and all attribute change list were finally submitted. The project was completed on time and delivered to the customer. At the same time, one or two process engineers are assigned from time to time for on-site real-time maintenance, and then P & ID data conversion and update work are carried out periodically according to the amount of tasks.

-Nanjing-SP P & ID

customer proposed the need to convert more than 1000 drawings of olefin and polyethylene plants, and need to improve relevant equipment parameters and pipe properties. After more than one year's efforts, a number of finished products including P & ID system backup files, equipment list, pipeline list, etc. were finally submitted, and all P & ID diagrams were successfully released to SPF system, and related documents of equipment, pipelines and instruments with corresponding tag numbers were associated. The project was completed on time and delivered to customers.

Heat Exchanger Process Design and Accounting Case 2013-Nanjing-Aspen Plus, Aspen EDR

a reboiler fouling is serious and the shell side cleaning is difficult. The tube spacing is changed from 32mm to 36mm without changing the inner diameter of the reboiler shell and tube specifications. The process accounting of the original reboiler and the transformation scheme was carried out by using Aspen EDR software, and the transformation scheme met the process requirements. (screenshot)

Distillation Column Condenser Retrofit Case 2012-Nanjing-Aspen EDR

, the product has been unable to meet the requirements. After the process simulation calculation and analysis, it is found that the main reason for the unqualified product of the tower top is that the cooling water of the top condenser tube side cannot reach the design flow rate and cannot meet the condensation needs. The condenser is changed from the original 8 tube to 4 tube, and the heat exchange tube is changed from a smooth tube to a high-efficiency heat transfer tube. After the transformation, the operation is stable, and the purity of the top product reaches the standard.
