Process description for the H2 example simulation

This example reproduces the published case of the reference case by Sumaria2. The process consists of the following:

• Cooling water on the tube side cools the methanator effluent gas on the shell side.

• The low-pressure side of the heat exchanger has two passes with half-circle shaped inlet channels and a full circle shaped return channel.

• The relief valve is on the inlet channel. The relief valve size has an area of 7135 mm2 (11.06 in2) and the mass of its moving parts is 50.8 kg (112 lb).

• We assume a 298.5 mm ID (11.75 in) cooling water header supplies the cooling water. It connects to the heat exchanger through 154 mm ID (6.065 in) laterals. The cooling water returns to a return header in a similar way through 154 mm ID (6.065 in) lateral and back into the 298.5 mm ID (11.75 in) cooling water return header.

• A single tube ruptures at the heat exchanger tubesheet, thus immediately introducing gas to the front channel.
