Bed length of adsorption unit

Input(s)

x: Maximum Desiccant Useful Capacity (kg water/100 kg desiccant)

$\mathrm{x}_{\mathrm{s}}$: Dynamic Capacity at Saturation ( $\mathrm{kg}$ water $/ 100 \mathrm{~kg}$ desiccant)

$\mathrm{h}_{\mathrm{z}}$: MTZ Length $(\mathrm{ft})$

Output(s)

$h_{b}$: Bed Length $(\mathrm{ft})$

Formula(s)

$$ \mathrm{h}_{\mathrm{b}}=\frac{0.45 * \mathrm{~h}_{\mathrm{z}} * \mathrm{x}_{\mathrm{s}}}{\mathrm{x}_{\mathrm{s}}-\mathrm{x}} $$
