Vertically mounted temperature connection

Altliough some reactors (e.g., those u.sed in methanol and catalytic reforming units) are. spherical, most are vertically mounted ve.ssels with elliptical heads. There are fewer connections for the plant layout designer to be concerned with than there are with the dLstillation tower. Generally, connections are limited to inlet and outlet, maintenance access, unloading,. sample, and temperature. Internally, reaaors are furnished with bed supptms, screens, inlet baffles, outlet collectors, catalysts, and inert materials. Exhibit 9-3 depicts a typical reactor and its principal components. 

In our institute we have developed a simple reciprocating piston engine by omitting mechanically operated control valves. In Fig. 1 a cross section of this new engine is shown. The cylinder (1) is mounted on a stainless steel tube (3) which is connected with the driving gear operating at room temperature. The piston (2), shown in its upper end position, is flexibly connected to the piston rod (4), which also consists of a stainless steel tube and works on a simple crankshaft. The upper end of the piston rod is constrained to move in the vertical direction in order to avoid lateral forces on the piston.
