Plate and frame heat exchangers are preferred for crude oil cooling service. If your crude has Wax then depending on the wax appearance temperature a proper flow direction should be selected. As per NORSOK-P-100, generally cooler should be co-current to avoid/reduce waxing. But if the wax appearance temperature is less than the cold medium (generally sea water or sea water cooled medium) inlet temperature, a counter-current heat exchanger is recommended.

Let me know if it anwsers your question.
