Heat exchanger performance

(OP)
Good Morning guys,

I'm wondering if you can help, I'm relatively new to the hydrocarbon processing industryand I would be the first to admit to not having a chemical engineering degree so my under standing of the physics or the chemistry does sometimes prove problematic but in advice given would be greatly appreciated

We have a heat ex-changer that's over efficient, this creates a problem down stream as the temperature of the process gas coming discharging of the heatrix is to cold and is creating problems ef further down stream. The process team have suggested that we drop the operating pressure of the cooling medium system thus increasing the temperature on the outlet of the heatrix. The mechanical issues are getting ironed in terms of valve replacements but this is there interim solution.

My issue is perhaps " simple" to you boffins but am I understanding that by dropping the pressure through the ex changer, i m actually decreasing the flow rate thus less heat transfer or is it connect to the boiling properties of the Cooling medium system when under pressure thus less heat transfer when pressure decreased.

I'm aware that this question is relatively simple in relation to the rest of questions on this site but I would really appreciate some advice or even a gentle push in the right direction.

Cheers
