Formaldehyde (100MM LBS/YR) Plant

Specifications

100 MM LBS /Year

Process Details:

á   Silver Catalyst based conversion of methanol

á   Steam (at maximum rates the total steam consumed

    is approx. 12,600 KG/HR of 75# steam. 80% is used

    in the distillation column. The remaining is used in the

1987

    super heater and the heating coil in the top of the

    reactor. Approximately 7600 KG/HR of the steam

Year Closed:

    used was produced by the reactor).

á   Cooling water (2500 M3/HR at 100% capacity)

Feedstock:

á   Instrument Gas

á   Nitrogen Demineralized water

á   Stream Factor: 98%

Methanol (100%) 1.19 pounds of methanol to produce

1.0 pound of formaldehyde 50% formaldehyde with 0.7%

methanol and 0.010 PPM formic acid produced.

Dilution to other concentrations is possible.

Number of Instrument Control loops: 243

á   (9) PLATE EXCHANGERS

á   (1) SHELL/TUBE EXCHANGER

á   (18) PUMPS

á   (3) VACUUM PUMPS

á   (1) REACTOR

á   (2) DISTILLATION COLUMNS

á   (1) ABSORBER COLUMN

á   (1) SATURATOR COLUMN

á   (1) INTERMEDIATE VESSEL

á   (1) NITROGEN VESSEL

á   (1) FLAME TRAP

á   (1) GAS SUPER HEATER

á   (1) STEAM CYLINDER

á   (1) CONDENSATE VESSEL

á   (2) REBOILERS

á   (1) EXCESS METHANOL VESSEL

á   (1) CIRCULATION VESSEL ON VACUUM SYSTEM

In 1997, the used plant has a new distillation column and

saturator column, and replacing sections of the

absorption columns (to allow for higher throughput).
