IPC: F28B3/04
Filed: 1978-06-06
Abstract: PURPOSE: To provide a direct contact type condenser which can obtain preferable heat transmission performance, extremely low pressure loss and collect smoothly non-condensed gas even when steam flow velocity distribution is not regular.  
     CONSTITUTION: Coolant water is flown from an inlet tube 33 into a coolant water chamber 34, and distributed therefrom into a pair or a number of pairs of coolant water reservoirs 35. Then, the coolant rises in an injection tube 38 to inject in conical shape from a spray nozzle 39, and partially collides with a buffle plate 43 to thereby drop into a hot well 37 and to thus thermally exchange with the steam to be thus heated and to be thereafter exhausted externally from and exhaust tube 44. The exhaust steam flown into a condenser body 31 via the inlet 32 thermally exchanges with coolant injected from the nozzle 39. Non-condensed gas thus thermally exchanged is exhausted from a passage 42 through a reservoir 40 into an extraction tube 41. In this case, the non-condensed gas rises without being obstracted by the coolant thus injected from the nozzle 39 to thereby provide low pressure loss.

Title: Manufacture of formic acid by hydrolysis of methyl formate
Inventor: JIYAKUSON DEII REONAADO
IPC: C07C51/09
Filed: 1979-06-05
Abstract: The invention provides a process for the preparation of formic acid by hydrolyzing methyl formate with water at high temperature and pressure in the presence of a formic acid catalyst. Methanol is also formed. The reesterification of the reaction products to methyl formate (a reaction favored by high temperatures) is minimized by flashing the reaction product at relatively low pressure and temperature and thereafter distilling the residual liquid. Thus procedure separates the methyl alcohol from the formic acid with a minimum contact time and at a low temperature which does not favor the reesterification reaction. High purity formic acid may be obtained by subjecting the bottom from the vacuum distillation of further distillation. 
<??>In a preferred embodiment of the invention, prior to the main hydrolysis, the methyl formate is partially hydrolyzed to form the small amount of formic acid needed to accelerate the main hydrolysis step. Accordingly, the necessary formic acid catalyst is formed in situ, thus eliminating the need to add formic acid or to recycle product formic acid.
