DCS automatic control

2020-09-21View Original

Thread Content

Our facility has a process that requires a temperature reduction of 1° within one hour; this degree of cooling is too small. What type of instrument can be used in a DCS system to achieve this? I’m seeking advice from experts.

It’s stated in very general terms: DCS is DCS, and instruments are instruments; control should be carried out using instruments with high precision. The DCS does have certain functional blocks such as those for controlling ramps, but to determine exactly how much the temperature needs to drop per hour, programming would be required – yet this may not be feasible, as the precision is too low

"The process requires a temperature reduction of 1° within one hour; this reduction is too small.” Isn’t it needed? Why do you think it’s too small again? It’s recommended to first clarify the process requirements and the methods for cooling.

From the DCS perspective, it is a control program. The key is measuring the temperature at the site, and that’s not too difficult either ; The key is how this cooling is achieved: how is heat removed?
